M-series Routing Platforms

Juniper Networks M-series routers deliver the same features and predictable performance
across platforms. This consistency accelerates time to revenue, improves cost efficiency
while scaling the network, and decreases operational overhead.

M-series Routing Platforms

Juniper Networks M-series Multiservice Edge platforms are deployed in the world's largest networks
delivering advanced IP/MPLS services at scale, enabling service providers to reduce costs through network
consolidation while simultaneously generating new revenues. Constructed with a clean separation between
control plane, forwarding plane, and services plane, M-series routers support multiple services over any type
of access connection without compromise on a single platform - maximizing revenue and minimizing
operational and capital costs. These services include a broad array of VPNs, network-based security, real-time
voice and video, bandwidth on demand, rich multicast of premium content, IPv6 services, granular
accounting and much more. This service portfolio continues to grow with every release of JUNOS software,
leveraging the tremendous flexibility and performance headroom of the service-built architecture.

Enhanced for the Edge

The M-series platforms are extremely versatile as they can be deployed at the edge of provider networks, in
small and medium cores, and in peering, route reflector, and data center applications. However, recent M­series platforms innovations have dramatically expanded their edge capabilities by leveraging the highly
programmable Internet Processor II ASIC and IP/MPLS-rich JUNOS software. M-series routers are now
deployed and scaling services at the edge of some of the world's largest production networks.

Consistent Services to All Customers

The M-series platforms boast a portfolio that spans from 5 Gbps up to 320 Gbps of throughput, including
the M7i, M10i, M20, M40e, M160, and M320 platforms. Because the same scalable and production­hardened JUNOS software runs on all M-series platforms, a consistent set of capabilities is available at all
network locations regardless of customer connection or serving area density.

Access Agnostic with Leading Density

With its broad interface portfolio, a single M-series platform can provide a single point of edge aggregation
for thousands of customers over any access type including ATM, Frame Relay, Ethernet, and TDM as well as
at any speed from DS0 up to OC-192/STM-64 and 10 Gigabit Ethernet. Leveraging dense Ethernet and
highly channelized interfaces, the M-series platforms boast leading densities for virtually all port types.

Most Comprehensive VPN Portfolio

The M-series platforms also support the industry's most comprehensive VPN portfolio with the ability to
simultaneously run and scale Layer 2 virtual circuits, Layer 2 VPNs, Layer 2.5 Interworking VPNs, Layer 3
2547 VPNs, VPLS, IPSec, GRE, IP over IP and other tunneling mechanisms with no performance
compromise. This broad set of VPNs meets the needs of the widest possible set of customers, maximizing
the service provider's revenue while minimizing required infrastructure. For example, a provider can use
Layer 3 VPNs to deliver an outsourced routing service and can also use Layer 2 VPNs to provide a point-to­point ATM service over a common IP/MPLS infrastructure.

Granular QoS and Statistics

Rich packet processing enables the M-series platforms to support multiple levels of granular QoS per-port,
per-logical circuit (DLCI, VC/VP, VLAN), and per-channel (to DS0) for traffic prioritization. These
comprehensive QoS functions include classification, rate limiting, shaping, weighted round robin scheduling,
strict priority queuing, weighted random early detection, random early detection, and packet marking. For
network convergence applications, Layer 2 CoS can be mapped to Layer 3 CoS on a per DLCI, per VP/VC, or
per VLAN basis. Simultaneously, extensive statistics can be collected and diagnostics performed at this same
level of granularity to enable flexible billing, traffic planning, and rapid troubleshooting.

Rich Packet Processing

A broad portfolio of services can be layered on top of VPNs for additional
revenue generation. A comprehensive suite of multicast capabilities, including
multicast over MPLS VPNs, enables efficient distribution of premium content.
Hardware-based IPv6 and a number of IPv6 migration tools such as IPv6 over
MPLS ease access to the benefits of this next-generation IP protocol without
performance compromise. NAT and stateful firewall can be configured per VRF
to enable network-based security for additional revenues and IPSec can be
used to support a premium security service for end users with high security
requirements. The M-series Service-Built Edge is continuously enhanced with
new packet processing capabilities to ensure maximum revenue generation
opportunities.

Highly Reliable

The M-series service-built architecture has been fundamentally constructed with
scale and stability in mind, including the modular and fault-protected design of
JUNOS software along with a rigorous system testing process. Furthermore, all
M-series routers offer redundant power and cooling and the M10i, M20, M40e,
M160, and M320 offer fully redundant hardware including redundant Routing

Key Components

Key components of each M-series router are the Packet Forwarding Engine
(PFE) and the Routing Engine.

• The PFE is a logical entity that is responsible for packet forwarding. It
physically consists of the PICs, FPCs, FIC, control/system/forwarding
board, and state-of-the-art ASICs

• Physical Interface Cards provide a complete range of fiber optic and
electrical transmission interfaces to the network. For a listing of
available PICs, see the M-series PICs and FPCs datasheet.

• Flexible PIC Concentrators house PICs and connect them to the rest of
the PFE. FPCs parse, prioritize, and queue the packets before
forwarding them across the midplane to the appropriate destination
interface. On egress, FPCs prioritize, queue, re-assemble, and forward
packets out through the appropriate port. Up to four PICs can be
mixed and matched within a single FPC slot, increasing configuration
flexibility and network scalability, while maximizing POP efficiency.

The FPC required depends on the platform and on the PICs that are
needed. For a listing of available FPCs, see the M-series PICs and FPCs
datasheet.

• The Fixed Interface Concentrator is available only on the M7i and
contains either 2 fixed Fast Ethernet interfaces or 1 fixed Gigabit
Ethernet Interface. The Gigabit Ethernet interface requires Small Form
factor Pluggable optics (SFP ordered separately).

• On M7i, M10i, M20, M40e, and M160 platforms, the
control/system/forwarding board performs route lookup and switching
to the destination FPC. It makes forwarding decisions, distributes data
cells throughout memory, processes exception and control packets,
monitors system components, and controls FPC resets. There are
different names for this component on various platforms:

• M7i/M10i Compact Forwarding Engine Board

• M20 System and Switch Board

• M40e/M160 Switching and Forwarding Module

• M320 uses a distributed architecture, where the PFE is contained
entirely within the FPC. Route lookup and packet processing occurs
on the ingress PFE, and is then switched across the Switch Interface
Board (switching fabric) to the egress PFE for final route lookup and
packet processing. The feature-rich programmable ASICs deliver a
comprehensive, hardware-based system for packet processing and
support uncompromising 40 Gbps performance per PFE. To ensure a
non-blocking forwarding path, all channels between the ASICs and
between ingress and egress PFEs are oversized, dedicated paths.

• The feature-rich programmable ASICs deliver a comprehensive,
hardware-based system for packet processing. To ensure a non­blocking forwarding path, all channels between the ASICs are
oversized, dedicated paths.

• The Routing Engine maintains the routing tables and controls the routing
protocols, as well as the JUNOS software processes that control the router's
interfaces, the chassis components, system management, and user access to
the router

• The Routing Engine processes all routing protocol updates from the
network, so forwarding performance is not affected.

• The Routing Engine implements each routing protocol with a
complete set of Internet features and provides full flexibility for
advertising, filtering, and modifying routes. Routing policies are set
according to route parameters, such as prefixes, prefix lengths, and
BGP attributes.
