AGENDA

¢ What is B-RAS? ¢ Why we use it? ¢ Its functions/tasks¢ Brief view of network topology which consist of B-RAS

3

¢ Broadband Remote Access Server is a specialized server based at an ISP network that facilitates the convergence of multiple Internet traffic sources. � (These sources include cable, DSL, Ethernet or

broadband wireless)� It routes traffic to and from broadband remote access

devices, including DSL access multiplexers and theISP's network.

WHAT IS B-RAS?

¢ The BRAS sits at the core of an ISP's network, and aggregates user sessions from the access network.

[So far as I am aware of and lazy to research RedbackNetworks is a company which provide powerful BRAS/BNG(SmartEdge service gateway). This company was acquired byEricsson in December,2006]

WHAT IS B-RAS? (CONT.)

¢ The key benefits of using it are:� They provide a single point for change control� B-RAS is a common, access-agnostic operational

model� It is multiservice access node (MSAN) independent

<If network changes are required, it’s better to make changes at a single B-RAS server than at dozens of devices.

☻Sometimes we do not need to have WHY to everything. It is just something has to be used!

WHY WE USE IT?

¢ Aggregates the circuits from one or more link access devices

¢ Provides layer 2 connectivity through either transparent bridging or PPP sessions over Ethernet or ATM sessions

¢ Enforces quality of service (QoS) policies¢ Provides layer 3 connectivity and routes IP traffic

through an ISP’s backbone network to the Internet…
