EGPExterior Gateway Protocol. A reachability routing protocol used by gateways in a two-level internet. There is also a routing protocol called EGP defined in RFC 904. See core gateway.
EIAElectronic Industries Association. A national trade organization that publishes hardware oriented standards for data communications.
EIA-232is a specification of the EIA for what was previously known as RS232. Frequently these terms are inter-changed.
EKTSElectronic Key Telephone Service
EMIElectrical Magnetic Interference
EFMEthernet in the First Mile
EMSElement Management System
EN 50121-4Electromagnetic Compatibility Part 4 - European standard for railway applications. Emission and immunity of the signaling and telecommunications apparatus.
encapsulationThe technique used by layered protocols in which a layer adds header information to the protocol data unit (PDU) from the layer above. As an example, in Internet terminology, a packet would contain a header from the physical layer, followed by a header from the network layer (IP), followed by a header from the transport layer (TCP), followed by the application protocol data.
encryptionEncryption is the manipulation of a packet's data in order to prevent any but the intended recipient from reading that data. There are many types of data encryption, and they are the basis of network security. See DES, DEK, RSA, PGP.
end systemAn OSI system which contains application processes capable of communicating through all seven layers of OSI protocols. Equivalent to Internet host.
entityOSI terminology for a layer protocol machine. An entity within a layer performs the functions of the layer within a single computer system, accessing the layer entity below and providing services to the layer entity above at local service access points.

ESSElectronic Switching System
EthernetA 10Mbps standard for LANs, initially developed by Xerox, and later refined by Digital, Intel and Xerox (DIX). All hosts are connected to coaxial cable where thy contend for network bandwidth using a Carrier Sense Multiple Access with Collision Detection (CSMA/CD) paradigm. See l0Base-T.
Ethernet MeltdownAn event that causes saturation, or near saturation, on an Ethernet. It usually results from illegal or misrouted packets and typically lasts only a short time.
EunetEuropean UNIX Network. (Original name). Now a major European Internet Service provider.
EUUGEuropean UNIX Users Group. Now called EurOpen.
