A security feature that allows access to information to be granted on an individual basis.

The range of frequencies a transmission line or channel can carry. The greater the bandwidth, the greater the information-carrying capacity of a channel. For a digital channel this is defined in bits. For an analog channel it is dependent on the type and method of modulation used to encode the data.

A packet delivery system where a copy of a given packet is given to all hosts attached to the network. For example: Ethernet.

A server that is programmed to respond to redirected packets. Captive portals enable service providers to capture a subscriber’s attention with targeted messages such as authentication, requests for per-service payment, and blocked access to a particular service. A captive portal group consists of one or more servers. A captive portal group is identified by its unique name. Each server in a captive portal group is identified by its IP address and TCP port. SSG selects one server from the group in a round-robin fashion to receive the redirected packets. Servers can be in the SSG Open Garden or default network.

Cisco Express Forwarding. An advanced Layer 3 IP switching technology. CEF optimizes network performance and scalability for networks with large and dynamic traffic patterns such as the Internet, on networks characterized by intensive Web-based applications, or interactive sessions.
