11、elopment of IEEE Std 802.1DTM-1993 introduced the concept of Filtering Services in Bridged Local Area Networks, and mechanisms whereby filtering information in such LANs may be acquired and held in a Filtering Database. IEEE Std 802.1DTM, 1998 Edition, a revision of IEEE Std 802.1D-1993, extended th
12、is concept of Filtering Services to define additional capabilities aimed at a)The provision of expedited traffic capabilities, to support the transmission of time-critical information in a LAN environment. b)The use of signaled priority information as the basis for identifying expedited classes of t
13、raffic. c)The provision of filtering services that support the dynamic definition and establishment of Groups in a LAN environment, and the filtering of frames by Bridges such that frames addressed to a particular Group are forwarded only on those LAN segments that are required to reach members of t
14、hat Group. d)The provision of a Generic Attribute Registration Protocol (GARP) that is used to support the mechanism for providing Group filtering capability and is made available for use in other attribute registration applications. This standard, first published as IEEE Std 802.1Q-1998, makes use
15、of the concepts and mechanisms of LAN Bridging that were introduced by IEEE Std 802.1D, and it defines additional mechanisms that allow the implementation of Virtual Bridged Local Area Networks. The following mechanisms are described: e)Virtual LAN Services. f)The operation of the Forwarding Process
16、 that is required. g)The structure of the Filtering Database that is required. h)The nature of the protocols and procedures that are required to provide Virtual LAN services, including the definition of the frame formats used to represent VLAN identification information, and the procedures used to i
17、nsert and remove VLAN identifiers and the headers in which they are carried. i)The ability to support end-to-end signaling of priority information regardless of the intrinsic ability of the underlying MAC protocols to signal priority information. j)The GARP VLAN Registration Protocol (GVRP) that all
18、ows distribution and registration of VLAN membership information (the protocol described makes use of the GARP protocol defined in ISO/ IEC 15802-3). k)The management services and operations that are required to configure and administer networks. The 2003 Edition of the standard incorporated three a
19、mendments, IEEE Std 802.1uTM-2001, IEEE Std 802.1vTM-2001, and IEEE Std 802.1sTM-2002, into the text of IEEE Std 802.1Q-1998. These amendments describe enhancements to the standard to allow l)Dynamic Group and VLAN registration to be restricted, based on the contents of static filtering entries. m)V

22、of the standard is the result of balloting the 2003 Edition, along with maintenance changes to align the text with improvements made to IEEE Std 802.1D. This standard contains state-of-the-art material. The area covered by this standard is undergoing evolution. Revisions are anticipated within the n
23、ext few years to clarify existing material, to correct possible errors, and to incorporate new related material.
