Extended Binary Coded Decimal Interchange Code. This 8-bit encoding scheme for character data was developed by IBM. See also ASCII.
Exterior Border Gateway Protocol. This is the part of the BGP protocol that ASBR devices use to communicate with other ASBR devices from different Autonomous Systems.
Exterior Gateway Protocol. Generically, an exterior gateway protocol is a dynamic routing protocol used to connect two or more Autonomous Systems. A good example is BGP. However, an older protocol called EGP performs a similar function.
Enhanced Interior Gateway Protocol. Based on the earlier IGRP protocol, EIGRP is a dynamic routing protocol developed by Cisco systems. It uses a Distance Vector algorithm and is capable of providing dynamic routing for TCP/IP, IPX, and Appletalk.
Emulated LAN. In ATM LAN Emulation, an ELAN is the equivalent of a VLAN.
Device that does not take part in any network functions such as bridging or routing.
Extended Service Set. In 802.11 wireless LAN technology, an ESS is a collection of BSS units. It may or may not support roaming, depending on the architecture.
A LAN technology defined by the IEEE in the 802.3 specification. In one common set of implementations, Ethernet uses a bus topology with the CSMA/CD collision mechanism for handling congestion. Alternatively, Ethernet can be configured as a star topology using full-duplex communication to avoid collisions.
Ethernet II is an older version of Ethernet that predates the more modern 802.3 specification, although it interoperates well with it. Almost all TCP/IP implementations use Ethernet II.
Early Token Release. In Token Rings, Early Token Release is the ability of some devices to distribute a new token on the ring after they have finish sending but before they received confirmation that all of their frames were received.
