System Overview
The SmartEdge 100 router is a carrier-class product with an architecture that supports packetized traffic.
The SmartEdge 100 router can be used as an edge aggregation router and simultaneously as a broadband
remote-access server (BRAS) to directly connect customers to the network. It supports a variety of
interfaces and vital services, such as routing protocols, quality of service (QoS), and inbound and outbound
access control lists (ACLs). New services can easily be added with software upgrades.
Because of the optimized packet forwarding capabilities and support of high-bandwidth uplink interfaces,
the SmartEdge 100 router can also be used in the metropolitan core to aggregate traffic from other routers
into the long-haul transit core. The SmartEdge 100 router supports a wide variety of interfaces, such as
Ethernet 10Base-T, 100Base-TX, 100Base-FX, 1000Base-FX, and 1000Base-T.
