Glossary

PVP

PXF

Permanent virtual path. Virtual path that consists of PVCs.

Parallel Express Forwarding. Also referred to as fast forwarder. A pipelined, multiprocessor parallel packet engine, optimized for fast packet forwarding.

R

RADIUS

RBE

Remote Authentication Dial-In User Service (RADIUS). A client/server security protocol created by Livingston Enterprises. Security information is stored in a central location, known as the RADIUS server.

Routed bridge encapsulation. The process by which a stub-bridged segment is terminated on a point-to-point routed interface. Specifically, the router is routing on an IEEE 802.3 or Ethernet header carried over a point-to-point protocol such as PPP, RFC 1483 ATM, or RFC 1490 Frame Relay.

S

SESM

Subscriber Edge Services Manager (SESM). Successor product to the Cisco SSD. The SESM is part

 

of a Cisco solution that allows subscribers of digital subscriber line (DSL), cable, wireless, and dialup

 

to simultaneously access multiple services provided by different Internet service providers, application

 

service providers, and corporate access servers.

 

SESM works with the Cisco 10000 router (as the SSG node) to provide subscriber authentication,

 

service selection, and service connection capabilities to subscribers of Internet services. Subscribers

 

interact with the SESM web application using a standard Internet browser. The SESM functionality

 

provides a flexible and convenient graphical user interface (GUI) for subscribers and enables service

 

providers to bill subscribers for connection time and services used, rather than charging a flat rate.

SSD

Service Selection Dashboard. The SSD is a customizable web-based application that works with the

 

Cisco SSG to allow end customers to log in to and disconnect from proxy and passthrough services

 

through a standard web browser. After the customer logs in to the service provider’s network, an HTML

 

dashboard is populated with the services authorized for that user. See also SESM.

SSG

Service Selection Gateway. SSG is a switching solution for service providers who offer intranet,

 

extranet, and Internet connections to subscribers using broadband access technology such as digital

 

subscriber lines (DSL) lines, cable modems, or wireless to allow simultaneous access to network

 

services. SSG provides subscriber authentication, service selection, and service connection capabilities

 

to subscribers of Internet services. SSG provides connectivity to corporate networks and differential

 

service selection to users with access to multiple simultaneous services. Users can dynamically connect

 

to and disconnect from any of the services available to them.

SVC

Switched virtual circuit. Virtual circuit that is dynamically established on demand and is torn down

 

when transmission is complete. SVCs are used in situations where data transmission is sporadic. Called

 

a switched virtual connection in ATM terminology. Compare with PVC.
