Glossary
Permanent virtual path. Virtual path that consists of PVCs.
PVP
Parallel Express Forwarding. Also referred to as fast forwarder. A pipelined, multiprocessor parallel
PXF
packet engine, optimized for fast packet forwarding.
R
Remote Authentication Dial-In User Service (RADIUS). A client/server security protocol created by
RADIUS
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
RBE
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
Subscriber Edge Services Manager (SESM). Successor product to the Cisco SSD. The SESM is part
SESM
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.
Service Selection Dashboard. The SSD is a customizable web-based application that works with the
SSD
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.
Service Selection Gateway. SSG is a switching solution for service providers who offer intranet,
SSG
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.
Switched virtual circuit. Virtual circuit that is dynamically established on demand and is torn down
SVC
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.
