Information Technology - Telecommunications and Information Exchange between Systems - Local and Metropolitan Area Networks - Technical Reports and Guidelines - Part 5: Media Access Control (MAC) Bridging of Ethernet V2.0 in Local Area Networks
|Publication Date:||15 August 1997|
For the purpose of facilitating the interoperability of ISO/IEC 10038 MAC Bridges and end stations in bridged LANs comprising CSMA/CD networks containing a mixture of ISO/IEC 8802-3 and Ethernet end stations and other types of LANs, this Technical Report specifies extensions to the behavior of MAC Bridges. To this end this Technical Report
a) Extends the Bridge service interface model to support multiple MAC services on a single LAN and to add a Bridge-Tunnel service interface.
b) Defines the Selective Translation Algorithm used by a Bridge to convert between Ethernet and ISO/ IEC 8802 frame formats.
c) Defines the protocols used by a Bridge to convey Ethernet frames across ISO/IEC 8802 LANs, the Bridge-Tunnel Encapsulation Protocol, and the RFC1042 Encapsulation Protocol.
Additionally, for the purpose of avoiding future incompatibilities, this Technical Report provides guidelines for the development of nonstandard ISO/IEC 8802 protocols, with particular emphasis on conversion of existing Ethernet protocols and the behavior to be expected from a Bridge.
