What is the Centillion 1200N Switch?

The Centillion 1200N is a compact desktop 2.5 Gbps ATM Switch.
At the core is an input/output buffer switch that realizes a 2.5 Gbps nonblocking

throughput. The ATM Switch can accommodate up to four lines of 622 Mbps
interface conformi ng to the ATM Forum and ITU-T recommendati ons and up to 16
lines of 155 Mbps interface.

XATOM (eXpandable ATM Output Modula r Switch), the core of the ATM Switch,
is equipped w ith a la rge-capac ity buffer to ensu re the smoot h flow of mul timedi a
traffic and provide a powerful support to multimedia communications.

The ATM Switch supports both fixed path, or permanent virtual connections
(PVC), and var iable path, or switch ed virtual connec tions (SVC), and featur es such
functions as ATM cell priority control, congestion control, and traffic monitoring.
In addition, by using the SNMP protocol, the ATM Switch can interface with a
network management system (NMS).

Features

2

The ATM Sw itc h is a de skt o p ATM switch used for su ch ap pli c at ion s a s LAN - to­LAN connection. The ATM Switch serves as the core of an ATM users' network.

The features of the ATM Switch are described below.

Realizes 2.5 Gbps throughput

■

As the ATM Switch employs an output buffer type ATM switch with a

random access input-output buff er, it realizes high-capacity switching at a

high-speed total throughput of 2.5 Gbps of maximum switching capacity (at

155 Mbps × 16 lines maximum). Consequently, the ATM Switch can be used

to build a high-speed multimedia network.

Has redundant configuration

■

Redundant configuration of power unit ensures high reliability.

Centillion 1200N ATM Switch User Manual 2-1
NTP 297-8103-903

Features What is the Centillion 1200N Switch?

Accommodates various ATM lines

■

The ATM Switch can interface various ATM lines by accommodating both
optical lines and metall ic li nes , different throughputs, and different pr ot ocol s.
Because the A TM Switch is equipped with interfaces for various A TM lines, it
can be used for a wide range of multimedia applications depending on the
need.

Structure of the ATM Switch

■

With its compact dimensions, the ATM Switch can be placed on a desktop or
on a standard 19-inch rack. To facilitate on-site maintenance after the
operation begins, the ATM Switch is designed to allow service access from
the front of each unit.

Supports various connection functions

■

As the ATM Switch supports both fixed connections (PVCs) and switch
connections (SVCs), it provides various connection formats.

Connections may be set to one of five levels of control priority

■

Total management of network

❑

Because the ATM Switch is equipped with a network management agent
function based on SNMP, it can be managed along with such LAN products
as routers and hubs.

Traffic control

■

When competit ion occurs in sending out cells, this traffic control function
prevents the cell with a higher priority from being delayed or discarded.

Each connection may be set to one of five levels of control priority.
Supports PNNI Ver.1.0

■

The ATM Switch is the world's first ATM switch to support PNNI Ver.1.0 that
conforms to the ATM Forum. This ensures that network construction is made
simple.

Provides server function

■

By installing a server card (option) in the line card slot, the ATM Switch can
be used as a LAN emulation server or an ARP server.

Total management of network

■

As the ATM Switch is equipped with a network management agent function
based on SNMP, it can be managed along with such LAN products as routers
and hubs.

Interworking with other types of networks

■

Interworking between ATM network and other types of networks can be
realized by installing an interworking line card (Frame Relay card FR-DS1)
and a Circuit Emulation card (CE-DS 1) in the AT M Switch.

What is the Centillion 1200N Switch? What is ATM?

Method of Expansion

The number of lines accommodated can be increased by connecting a number of
ATM Switch units. Line interface ca n be used to connect the ATM Switch units. An
interface dedicated to connections between units is not necessary. When a number
of the ATM Switch units are connected to increase the number of lines, the actual
number of lines accommodated is the total number of lines les s the number of lines
between the units.

What is ATM?

ATM, or Asynchronous Tra nsfer Mode, i s a communicati on method that wi ll serv e
as the basis for tomorrow's communication network, B-ISDN.

In ATM, all data in the network are exchanged in fixed-length, 53-byte blocks
called "cells." This allows much faster and broader communications compared to
the conventional STM or packet switching method.

The communication channels for cells are such virtual connections as VP (Virtual
Path) and VC (Virtual Channel). These are identified by the VPI (Virtual Path
Identifier ) and VCI (Virtual Channel Identifi er) st ored i n the 5-by te head er of eac h
cell.

Figure 2-4 is a conceptual diagram of VP and VC in an ATM network, and the

format of ATM cells.

What is the Centillion 1200N Switch? What is a Server Card?

What is a Server Card?

The Server Card is a CPU built-in card for realizing seamless connection with
existing LAN in an ATM network environment.

The card is mounted on ATM Switches, which serves as the core of an ATM
network, to provide LANE server, ARP server, and NHRP server functions.

Following are features of the server card:

Provides server functions conforming to various specifications

■

The software that provides the LA N emulation server functions is installed in

the card with a built-in CPU to facilitate the cons truction of LA N emulation.

By installing software with ARP server and NHRP server functions, it is

possible to eliminate bandwidth waste caused by conventional broadcast

address solution and improve the capacity of the network as a whole.

Hot-Swappable

■

The server card can be inserted into or removed from the ATM switching

system without affecting its switching functions.

Processor-to-processor communication function

■

Reciprocal communication is realiz ed between th e CPU in the serv er car d and

the CPU in the switching system. This function allows the switching system

to control the server card and also to control in an integr ated fashion the

switching system, along with other network equipment, with an NMS

(Network Management Syst em).

Allows the installation of several server cards

■

A number of server cards can be installed on a single ATM Switch.

Consequently, this facilitates the scalabl e expans ion of the serv er accor ding to

network size and enables the server to be operated in a redundant

configuration. In addition, this feature makes it possible to distribute the

traffic that had concentrated in the server with conventional networks.

LAN Emulation What is the Centillion 1200N Switch?

LAN Emulation

LAN emulation refers to the technology of using the existing infrastructure of a
LAN and connecting the LAN to a n ATM network on a br id ge level to emul ate th e
connection. The speci fication of LAN emulation has been standar dized by the ATM
Forum in its “LAN Emulation Over ATM Specification Version 1.0.”

LAN emulation allows existing LAN terminals to reciprocally communicate with
ATM terminals and make it possible to construct a virtual LAN that is free of
physical rest raints.

Figure 2-6 and Figure 2-7 show the LAN emul ation protocol stack between an ATM

terminal and an existing LAN terminal and its frame format when IP protocol is
used as the network layer.

ARP What is the Centillion 1200N Switch?

ARP

Address Resolution Protocol (ARP) is an address conversion protocol used to
resolve the MAC address (or ATM address) of a terminal from its IP address in a
subnet. ARP provides IPOA function which conforms to RFC 1577.

The ARP function pro vided by the Serv er Car d i s t o r es olve the ATM addresses o f
terminals in ATM-LAN. This function, in particular, is referred to as ATM ARP.

At least one ARP server is pla ced in a logical IP subnet (LIS) . Having an ARP table
(IP address-ATM address chart) that is periodically updated, the ARP server
resolves addresses of terminals in that LIS.

Shown in Figure 2- 9 is the addr ess resolu tion proced ure using an ARP serv er. (The
numbers correspond with the procedures that follow.)

2-10

Figure 2-9: Address Resolution Procedure Using an ARP Server

Each terminal, when connected to A TM-LAN, re gisters its o wn IP address and

ATM address with the ARP server. The ARP server uses the registered
addresses to prepare an ARP table.

When the transmission terminal has no connection with the destination

2.

terminal and has not cached the ATM address of the destination terminal, it
sends to the ARP server an address resolution request with the destination
terminal's IP address.

The ARP server , after rece iving the addr ess resolution request, checks the ARP
