Embodiment Construction

[0034] The Generic Framing Procedure (GFP) is defined in ITU-T G.7041 / T1X1.5 / 2001-024r4, which is a new type of data link framing protocol, mainly for block coding based on bit-synchronous transmission channels or for Packetized data flow.

[0035] GFP uses flexible frame encapsulation to support fixed or variable length data. GFP can fully encapsulate variable length user protocol data units (PDUs), eliminating the need for data splitting, reassembly and frame filling, simplifying It improves the operation of the system and improves the processing speed and stability of the system; at the same time, unlike the advanced digital link control (HDLC), GFP uses specific characters to fill the frame header to determine the frame boundary. GFP draws on the asynchronous transfer mode (ATM) frame positioning Method, using the self-describing technology based on frame header error check (HEC), through the two-byte payload length of the current frame and the two-byte frame header error ...

Abstract

This invention discloses one method on common frame rule to realize virtual local network, which uses the channel label and group label in the linear expansion frame probe of the common frame rule as 802.IQ agreement virtual local network label and uses the GFP linear expansion frame probe priority as the one in the 802.IQ agreement and uses the specimen frame indicator codes in the GFP linear expansion frame probe as 802.IQ agreement specimen indicator to divide the frame forms. This invention also discloses one common rule to realize virtual private network method.

Description

technical field [0001] The invention relates to the general framing procedure (GFP) technology in the field of communication, in particular to a method for realizing a virtual local area network (VLAN) and a virtual private network (VPN) on the GFP. Background technique [0002] The convenience and quickness of WEB business development has made people more and more aware of the benefits of the Internet, and many enterprises and companies have transferred many of their original businesses to the Internet, which has greatly increased the business volume of the network and further driven the Internet, especially WEB business. flourishing. Traditional voice telephony is also being transferred to voice over IP (VOIP), which is simple to manage, so the tariff can be lower, so it is clearly in an advantageous position in the competition with the traditional public switched telephone network (PSTN), which also drives the Internet development of. In addition, some new applications ...
