T1600 Router Description

The T1600 Core Router is a complete routing system that provides Gigabit Ethernet, SONET/SDH, and otherhigh-speed interfaces forlargenetworksand networkapplications, such as those supported by Internet service providers (ISPs). The T1600 router accommodates up to eight Flexible PIC Concentrators (FPCs), each of which can be configured with a variety of network media types. The router provides up to 800 gigabits per second (Gbps), full duplex (1600 Gbps of any-to-any, nonblocking, half-duplex) switching.

The router architecture cleanly separates control operations from packet forwarding operations. This design eliminates processing and traffic bottlenecks, permitting the router to achieve high performance.

•

Controloperations in the router are performed by thehost subsystem,which runsJunos operating system (Junos OS) to handle routing protocols, traffic engineering, policy, policing, monitoring, and configuration management.

•

Forwarding operations in the router are performed by the Packet Forwarding Engines, which consist of hardware, including ASICs, designed by Juniper Networks. Application-specific integratedcircuits (ASICs) are a definitive part of the router design; they enable the router to achieve data forwarding rates that match current fiber-optic capacity. The T1600 router provides up to a total of 1600 million packets per second (Mpps) of forwarding.

T1600 System Architecture Description

The T1600 Core Router has two main architectural components:

•

Routing Engine—This component provides Layer 3 routing services and network management.

•

PacketForwardingEngines—Thesehigh-performance,ASIC-basedcomponents provide Layer 2 and Layer 3 packet switching, route lookups, and packet forwarding.

Documentation

The Routing Engine and the Packet Forwarding Engines perform their primary tasks independently, although theyconstantly communicate through multiple 100-Mbps links. This arrangement streamlines forwarding and routing control and runs Internet-scale backbone networks at high speeds. Figure 3 on page 7 shows the relationship between the Routing Engine and the Packet Forwarding Engines.

T1600 Routing Engine Functions

The Routing Engine handles all routing protocol processes, as well as the software processes that control the router's interfaces, the chassis components, system management, and user access to the router. These routing and software processes run on topof a kernel that interacts withthe Packet Forwarding Engine. For more information about the processes, see the Junos OS System Basics and Services Command Reference.

The Routing Engine includes the following functions and features:

•

Processing of routing protocol packets—The Routing Engine handles all packets that concern routing protocols, freeing the PacketForwarding Engine to handle only packets that represent Internet traffic.

•

Softwaremodularity—Becauseeach software process is devoted to a different function and uses a separate process space, the failure of one process has little or no effect on the others.

•

In-depth Internet functionality—Eachrouting protocolis implemented with acomplete set ofInternet features and provides fullflexibility for advertising, filtering, andmodifying routes. Routing policies are set according to route parameters (for example, prefix, prefix lengths, and BGP attributes).

•

Scalability—The Junos OS routing tables have been designed to hold all the routes in current networks with ample capacity for expansion. Additionally, the Junos OS can efficiently support large numbers of interfaces and virtual circuits.

•

Management interface—Different levels of system management tools are provided, including the Junos OS command-line interface (CLI), the Junos XML management protocol, the craft interface, and SNMP.

•

Storage and change management—Configurationfiles, system images, and microcode can be held and maintained in primary and secondary storage systems, permitting local or remote upgrades.

•

Monitoring efficiency and flexibility—The router supports functions such as alarm handling and packet counting on every port, without degrading packet-forwarding performance.

The Routing Engine constructs and maintains one or more routing tables (see Figure 4 on page 9). From the routing tables, the Routing Engine derives a table of active routes, called the forwarding table, which is then copied into the Packet Forwarding Engine. The design of the ASICs allow the forwarding table in the Packet Forwarding Engine to be updated without interrupting forwarding performance.

T1600 Packet Forwarding Engine Architecture

The Packet Forwarding Engines provide the Layer 2 and Layer 3 packet switching, forwarding,and route lookup functions.The Packet Forwarding Engines are implemented in ASICs that are physically located on the FPCs and the PICs.

Each Packet Forwarding Engine consists of the following components (see “Data Flow Through the T1600 Router” on page 10):

•

Layer 2/Layer 3 Packet Processing ASIC, which performs Layer 2 and Layer 3 encapsulation and de-encapsulation, and manages the division and reassembly of packets within the T1600 router.

•

Queuing and Memory Interface ASICs, which manage the buffering of data cells in memory and the queueing of notifications.

•

T-series Internet Processor, which provides the route lookup function.

•

Switch Interface ASICs, which extract the route lookup key and manage the flow of data cells across the switch fabric.

•

Media-specific ASICs on the PICs that perform control functions tailored to the PIC media types.

Data Flow Through the T1600 Router

To ensure the efficient movement of data throughthe T1600 router,the routeris designed so that ASICs on the hardware components handle the forwarding of data. Data flows through the T1600 router in the following sequence (see Figure 5 on page 10):

Figure 5: Data Flow Through the T1600 Router

1. Packets arrive at an incoming PIC interface.

2. The PIC passes the packets to the FPC, where the Layer 2/Layer 3 Packet Processing

ASIC performs Layer 2 and Layer 3 parsing and divides the packets into 64-byte cells.

3. The Switch Interface ASIC extracts the route lookup key, places it in a notification and

passes the notification to the T-series Internet Processor. The Switch Interface ASIC also passes the data cells to the Queuing and Memory Interface ASICs for buffering.

4. The Queuing and Memory InterfaceASICs pass the data cellsto memoryfor buffering.

5. The T-series Internet Processorperforms theroute lookup and forwards the notification

to the Queuing and Memory Interface ASIC.

6. The Queuingand MemoryInterfaceASIC sends the notification to the Switch Interface

ASIC facing the switch fabric, unless the destination is on the same Packet Forwarding Engine. In this case, the notification is sent back to the Switch Interface ASIC facing

Page 35

Chapter 2: T1600 Router System Architecture Overview

the outgoing ports, and the packets are sent to the outgoing port without passing through the switch fabric (see Step 13).

7. The Switch Interface ASIC sends bandwidth requests through the switch fabric to the

destination port. The Switch Interface ASIC also issues read requests to the Queuing and Memory Interface ASIC to begin reading data cells out of memory.

8. The destination Switch Interface ASIC sends bandwidth grants through the switch

fabric to the originating Switch Interface ASIC.

9. On receipt of each bandwidth grant, the originating Switch Interface ASIC sends a

cell through the switch fabric to the destination Packet Forwarding Engine.

10. The destination Switch Interface ASIC receives cells from the switch fabric. It extracts

the route lookup key from each cell, places it in a notification, and forwards the notification to the T-series Internet Processor.

11. The T-series Internet Processor performs the route lookup, and forwards the

notification to the Queuing and Memory Interface ASIC.

12. The Queuingand MemoryInterfaceASIC forwards thenotification, including next-hop

information, to the Switch Interface ASIC.

Documentation

13. The Switch Interface ASIC sends read requests to the Queuing and Memory Interface

ASIC to read the data cells out of memory, and passes the cells to the Layer 2/Layer 3 Packet Processing ASIC.

14. The Layer 2/Layer 3 Packet Processing ASIC reassembles the data cells into packets,

adds Layer 2 encapsulation, and sends the packets to the outgoing PIC interface.

15. The outgoing PIC sends the packets out into the network.

T1600 Component Redundancy

The T1600 Core Router is designed so that no single point of failure can cause the entire system to fail. The following major hardware components are redundant:

•

Switch Interface Boards (SIBs)—The T1600 router has five SIBs.

•

Host subsystem—The host subsystem consists of aRouting Engine functioning together with a control board. The router can have one or two host subsystems. If two host subsystems are installed, one functions as the master and the other functions as the backup. If the master host subsystem (or either of its components) fails, the backup can take over as the master. Tooperate,each host subsystem requires aRouting Engine installed in an adjacent slot to a control board.

If the Routing Engines are configured for nonstop active routing, the backup Routing Engine automatically synchronizes its configuration and state with the master Routing Engine. Any update to the master Routing Engine state is replicated on the backup

Page 38

T1600 Core Router Hardware Guide

•

Routing Engine. If the backup Routing Engine assumes mastership, packet forwarding continues through therouter without interruption.For moreinformation about nonstop active routing, see the Junos OS High Availability Configuration Guide.

NOTE: Nonstop active routing is supported for standalone T1600 routers

in Junos8.5 and later. Nonstop active routing is supported forT1600 routers in a routing matrix in Junos 10.0 and later.

SONET Clock Generators (SCGs)—The router has a standard configuration of one SCG. A second can be purchased to function as backup. If one SCG fails, the other becomes the masterSCG.Mastershipof the SCGs isindependent of the host subsystem, so routing functions are not affected.

Power supplies—The router has two power supplies, which share the load evenly. If one power supply fails, the other power supply can provide full power to the router indefinitely.

Cooling system—Thecooling system has redundantcomponents, whichare controlled by the host subsystem. If one of the fans fails, the host subsystem increases the speed of the remaining fans to provide sufficient cooling for the router indefinitely.

T1600 FPC Function

FPCs house the PICs that connect the T1600 Core Router to network media. The main function of an FPC is to connect the PICs installed in it to the other T1600 router components. The Packet Forwarding Engine receives incoming packets from the PICs installed on the FPC and forwards them through the switch planes to the appropriate destination port. In a maximumconfigurationwith eightType4 FPCsinstalled,the Packet Forwarding Engines can forward up to 1600 million packets per second (Mpps) for all packet sizes. The T1600 Core Router provides up to 800 gigabits per second (Gbps), full duplex switching (1600 Gbps of any-to-any, nonblocking, half-duplex switching).

When you install an FPC into a functioning router, the Routing Engine downloads the FPC software, theFPC runs itsdiagnostics, and the PICs housed on the FPC, are enabled. Forwarding on other FPCs continues uninterrupted during this process.

T1600 FPC Slots

Up to eight FPCs install vertically in the front of the router. The FPC slots are numbered

FPC0 through FPC7, left to right. If a slot is not occupied by an FPC, an FPC blank panel

must be installed to shield the empty slot and to allow cooling air to circulate properly through the router.

T1600 FPC Components

Each FPC consists of the following components:

•

FPC card carrier.

•

One ortwo Packet ForwardingEngines, consisting of Layer 2/Layer 3 Packet Processing ASICs, Switch Interface ASICs, T-series Internet Processor ASICs, and a Memory Mezzanine Board (MMB) which includes the Queuing and Memory Interface ASICs.

•

Each Type 1 FPC has one Packet Forwarding Engine

•

Each Type 2 FPC has one Packet Forwarding Engine

•

Two LEDs, located on the craft interface above the FPC, that display the status of the FPC.

•

FPC online/offline button, located on the craft interface above the FPC.

T1600 FPC Terminology

Regardless of whether you are holding an FPC vertically or horizontally, this document uses the same terms for all four edges of the FPC (see Figure 9 on page 19):

•

Faceplate—Edge of the FPC that has slots into which you insert the PICs

•

Connectoredge—Edge opposite the faceplate;this edgehas the connectorsthat attach to the midplane

•

Top edge—Edge at the top of the FPC when it is vertical

•

Bottom edge—Edge at the bottom of the FPC when it is vertical

Figure 9: FPC Edges

Identifying the T1600 FPCs

Check the label on the faceplate to identify the FPC. For FPCs without a label on the faceplate, check the location of a PIC's offline button and how the PIC is secured to the FPC. See Table 3 on page 20.

T1600 PIC Description

PICs provide the physical connection to various network media types, receivingincoming packets from the network and transmitting outgoing packets to the network. During this process, each PIC performs framing and line-speed signaling for its media type. Before transmitting outgoing data packets, the PICs encapsulate the packets received from the FPCs. Each PIC is equipped with an ASIC that performs control functions specific to the media type of that PIC.

T1600 Front Cable Management System Description

The front cable management system (see Figure 18 on page 31) consists of a row of nine semicircular plastic bobbins mounted on the front of therouter below the FPC card cage. The PIC cables pass between the bobbins and into the tray, keeping the cables organized and securely in place. The curvature of the bobbins also helps maintain the proper bend radius for optical PIC cables.

You can pull the front cable management system up and outward to lock it into the maintenance position. This allows you to access the lower fan tray and the front air filter.

T1600 Rear Cable Management System Description

NOTE: The rear cable management system is not needed for standalone T1600 routers with T1600-SIBs and T-CBs.

For T1600 routers connected to a TX Matrix Plus router, you can use the rear cable management system to organize, support, and provide strain relief for the fiber-optic array cables connected tothe TXP-T1600SIBs, and the cablesconnectedto theLCC-CBs. The cables are routed to the left side of the T1600 router, and then toward the top of the chassis, where you can route the cables to the TX Matrix Plus router. The cable management system adds 9.5 in (24.1 cm) to the depth of the T1600 chassis, and 2.4 in (6.2 cm) to the left side of the chassis.

See the TX Matrix Plus Router Hardware Guide for instructions on installing and using the T1600 rear cable management system.

T1600 Host Subsystem Description

The host subsystem provides the routing and system management functions of the router. You can install one or two host subsystems on the router. The host subsystem consists of a Routing Engine and an adjacent control board. To operate, each host subsystem functions as a unit; the Routing Engine requires the corresponding control board, and vice versa.

Page 61

Chapter 3: T1600 Router Hardware Components Overview

NOTE: We recommend that you install two host subsystems for redundant

protection. If you install only one host subsystem, we recommend that you install it in slot RE0.

Each host subsystem has three LEDs, located on the upper right of the craft interface, that display its status. In addition, there are LEDs on each Routing Engine and control board..

T1600 Routing Engine Description

The Routing Engine runs the JunosOS. Software processes that run on the RoutingEngine maintain therouting tables, manage the routing protocols used on theT1600 Core Router, control the T1600 router interfaces, control some chassis components, and provide the interface for system management and user access to the router.

You can install one or two Routing Engines in the router. The Routing Engines install into the upperrear ofthe chassisin the slots labeled RE0 and RE1. Each Routing Engine requires a control board to be installed in the adjacent slot. RE0 installs below CB0, and RE1 installs above CB1. A Routing Engine does not power up without a control board present in the adjacent slot.

If two Routing Engines are installed, one functions as the master and the other acts as the backup.If the master Routing Engine fails or is removed and the backup is configured appropriately, the backup takes over as the master. If the host system is redundant, the backup Routing Engine is hot-removable and hot-insertable, but the master Routing Engine is hot-pluggable. A Routing Engine that is not redundant requires that you power down the router before replacement.

These functions include determining Routing Engine mastership, controlling power and reset for the other T1600 router components, monitoring and controlling fan speed, and monitoring system status.

You can install up to two control boards in the chassis. Control boards install into the upper rear of the chassis in the slots labeled CB0 and CB1 (referred to as CB-0 and CB-1, top to bottom). If two control boards are installed, one functions as the master and the

Page 70

T1600 Core Router Hardware Guide

other as its backup. If the master fails or is removed, the backup restarts and becomes the master.

Each control board requires a Routing Engine to be installed in the adjacent slot. CB0 installs above RE0, and CB1 installs belowRE1. Controlboards cannotfunction ifa Routing Engine is not present in the adjacent slot.

If the host system is redundant, the backup control board is hot-removable and hot-insertable, but the master control board is hot-pluggable. A control board that is not redundant is hot-pluggable.

The T1600 Core Router supports these control boards:

•

The T Series control board (T-CB) is supported in Junos OS Release 8.5 and later.

NOTE: The T-CB is required for a standalone T1600 router.

The line-card chassis control board (LCC-CB) is supported Junos OS Release 9.6R2 and later.

T1600 SONET Clock Generators (SCGs) Description

The SONET Clock Generators (SCGs) provide 19.44-MHz Stratum 3 clock signal for the SONET/SDH interfaces on the router (see Figure 31 on page 50).

One SCG is shipped as part of the standard router configuration, but up to two SCGs can be installed to provide redundancy. SCGs are installed into the upper rear of the chassis in the slots labeled SCG0 and SCG1.

A nonredundant SCG is hot-pluggable. For redundant SCGs, the master SCG is hot-pluggable. The backup SCG is hot-removable and hot-insertable if the master SCG is functioning. Removing the backup SCG does not affect the functioning of the router. Taking the master SCG offline might result in a brief loss of SONET clock lock while the backup SCG becomes the master.

T1600 Craft Interface Alarm LEDs and ACO/LT Button

Two large alarm LEDs are located at the upper left of the craft interface . The circular red LED lights to indicate a critical condition that can result in a system shutdown. The triangular yellow LED lights to indicate a less severe condition that requires monitoring or maintenance. Both LEDs can be lit simultaneously.

A condition that causes an LED to light also activates the corresponding alarm relay contact on the connector interface panel (CIP). The LCD on the craft interface reports the cause of the alarm.

To deactivate red and yellow alarms, press the button labeled ACO/LT (for “alarm cutoff/lamp test”), which is located to the right of the alarm LEDs. Deactivating analarm turns off both LEDs and deactivates the device attached to the corresponding alarm relay contact on the CIP. However, the LCD continues to report the alarm message until you clear the condition that caused the alarm.

T1600 Cooling System Description

The cooling system components work together to keep all router components within the acceptable temperaturerange. Figure 47on page 69shows theairflow through the router.

Figure 47: Airflow Through the Chassis

On steadilyYellowOVER

Off–

Power supply has exceeded recommended temperature.

If the DC OK and AC OK are on steadily, this LED indicates that power supply is within the recommended temperature.

The host subsystem monitors the temperature of the router components. When the router is operating normally, the fans function at lower than full speed. If a fan fails or the ambient temperature rises above a threshold, the speed of the remaining fans is automatically adjusted to keep the temperature within the acceptable range. If the ambient maximum temperature specification is exceeded and the system cannot be adequately cooled, the Routing Engine shuts down some or all of the hardware components.

Page 94

T1600 Core Router Hardware Guide

The cooling system consists of the following components:

•

All fan trays and filters are hot-insertable and hot-removable.

Two front fan trays—The standard front fan trays each contain six fans and are interchangeable. The standard front fan trays cool the components installed in the front card cage (the FPCs, PICs, CIP, and midplane).

Front air filter.

Rear fan tray—The rear fan tray contains eight fans and is not interchangeable with the front trays. The rear fan tray cools the components installed in the rear card cage (the Routing Engines, control boards, SCGs, and the SIBs).

Rear air filter.

Each power supply contains one fan that cools that power supply.

Rack Requirements for the T1600 Router

The router can be installed in many types of racks, including four-post (telco) racks and open-frame racks. An example of an open-frame rack is shown in Figure 48 on page 77.

For open-frame racks, center-mounting is preferable to front-mounting because the more even distribution of weight provides greater stability.

The router is designed for installation in a 19-in. rack as defined in Cabinets, Racks, Panels, and Associated Equipment (document number EIA-310-D) published by the Electronics Industry Association (http://www.eia.org).

With the use of adapters, the router can fit into a 600-mm-wide rack, as defined in the four-part Equipment Engineering (EE); European Telecommunications Standard for Equipment Practice (document numbers ETS 300 119-1 through 119-4) published by the European Telecommunications Standards Institute (http://www.etsi.org). Use approved wing devices to narrow the opening between the rails.

The rack rails must be spaced widely enough to accommodate the router chassis's external dimensions: 37.45 in. (95.1 cm) high, 31 in. (78.7cm) deep, and 17.43 in. (44.3 cm) wide, excluding the front and rear cable management systems. The outer edges of the mounting brackets extend the width to 19in. (48.3cm). The spacing of rails and adjacent racks must also allow for the clearances around the router and rack.

The mounting holes for connecting the mounting brackets to the chassis are spaced

0.984 in. (25 mm) apart.

The chassis height of 37.45 in. (95.1 cm) is approximately 21.4 U. A U is the standard rack unit defined in Cabinets, Racks, Panels, and Associated Equipment (document number EIA-310-D) published by the Electronics Industry Association. You can stack two routers in a rack that has at least 42.8 U (74.9 in. or 1.90 m) of usable vertical space.
