Description

A kind of adaptation method that is used for Ethernet and SDH (Synchronous Digital Hierarchy) or Synchronous Optical Network fusion

Invention field

The data that the invention belongs to Ethernet and SDH (Synchronous Digital Hierarchy) or Synchronous Optical Network transmit the field, it is a kind of adaptation method that Ethernet and SDH (Synchronous Digital Hierarchy) or Synchronous Optical Network merge that is used for, be specially a kind of how in SDH (Synchronous Digital Hierarchy) (english abbreviation is SDH) or the last method that transmits Ethernet and on Ethernet, how to transmit SDH (Synchronous Digital Hierarchy) or Synchronous Optical Network of Synchronous Optical Network (english abbreviation is SONET), be that conception of the present invention is mainly used in various communication equipments such as various router (core or the high-end switch router with various Ethernets or SDH (Synchronous Digital Hierarchy) or Synchronous Optical Network interface how in the method that transmits Ethernet/Fast Ethernet/gigabit Ethernet/10G Ethernet on the SDH/SONET network and how to transmit SDH/SONET on Ethernet/Fast Ethernet/gigabit Ethernet/10G Ethernet more specifically, edge or converge switch router, insert switch router), various high/medium/low end Ethernet switch based on grouping (bag) exchange, multi-service transport platform (english abbreviation is MSTP), the user side integrated access equipment, the equipment that Ethernet and SDH (Synchronous Digital Hierarchy) or Synchronous Optical Network are interconnected and with the relevant any equipment that interconnects of communicating by letter.

Background technology

According to relevant documents and materials, the technology that transmits Ethernet on SDH/SONET has three kinds, and the technology of transmission SDH/SONET is not also reported at present on Ethernet.The English saying that transmits Ethernet on SDH/SONET is Ethernet overSDH/SONET, abbreviates EOS as.The method that realizes EOS on the document has following three kinds:

(1) adopt " peer-peer protocol " (english abbreviation is PPP) to add " high-level data link rules " (english abbreviation is HDLC);

(2) adopt SDH Link Access Procedure (english abbreviation is LAPS);

(3) mode of employing Generic Framing Procedure (english abbreviation is GFP).

Wherein first kind of adaptation method with PPP+HDLC is a kind of method that is used for realizing internet (english abbreviation is IP) and SDH/SONET fusion that internet engineering task group (english abbreviation is IETF) defines, this scheme is by RFC2615, RFC1662, the RFC1661 definition of IETF, RFC can realize the transmission of Ethernet on SDH (Synchronous Digital Hierarchy) or Synchronous Optical Network in this way for request comment (English is Request For Comments); Second kind of method that adopts LAPS is X.85 and the X.86 a kind of Ethernet and the adaptation method of SDH determined of suggestion of ITU-T, and it is a kind of first method to be simplified the method for processing, and key element of its employing LAPS has replaced two key elements of PPP+HDLC; It is G.7041/Y.1303 a kind of adaptation method of standard of ITU-T that the third method promptly adopts the adaptation method of Generic Framing Procedure (GFP), in this adaptation method, use GFP as data link layer protocol, it can realize the adaptive of Ethernet and SDH, IP and SDH, IP and optical transfer network (english abbreviation is OTN), and this adaptation method still is that a kind of point-to-point connects the adaptation processing scheme in essence.

As everyone knows, Ethernet and SDH/SONET are the two big main flow communication technologys of present communication network, wherein Ethernet is main relevant with the internet, Ethernet be for data services particularly internet service be a kind of local area network technology that IP operation designs, owing to characteristics such as Ethernet has simply, standardization level is high, the paroxysmal IP operation of suitable transmission have occupied the local area network (LAN) market of the whole world more than 90%, and developing to Access Network and metropolitan area network direction; On the other hand, the SDH/SONET technology is the present main tranmission techniques of telecommunications backbone net in the world, and the interconnected tranmission techniques that communication network adopted in the whole world that people set up for the transmission voice service is exactly SDH (SDH is SONET the North America correspondence).In order to reduce network layer, reduce the networking cost of network, the transmitting range of expansion Ethernet, people's nature has just expected how transmitting the problem of Ethernet on SDH/SONET, this has just caused the generation of EOS technology, therefore above-mentioned three kinds of EOS adaptation techniques have been produced, but because Ethernet and SDH/SONET technology are two kinds of distinct tranmission techniques, Ethernet is fit to transmit Packet Service on the one hand, and SDH/SONET is a kind of time-division multiplex technology, suitable platform transmits the traditional voice transmission that adopts time-division multiplex technology, Ethernet all has different interface rate ranks with SDH/SONET on the other hand, because what above-mentioned three kinds of adaptation methods mainly solved is the Ethernet problem that point-to-point transmits on SDH/SONET, therefore above-mentioned three kinds of adaptation methods come with some shortcomings and defective:

What (1) above-mentioned three kinds of adaptation methods mainly solved is the point-to-point connectivity problem, because Ethernet belongs to different transmission technologys with SDH/SONET, the both has interface rate system separately, therefore there is the unmatched problem of speed in above-mentioned three kinds of adaptation methods, and need use the Virtual Concatenation of higher order virtual container and Lower Order Virtual Container at SDH/SONET, increased the complexity of an equipment.

(2) above-mentioned three kinds of adaptation methods all are the schemes that transmits Ethernet on SDH/SONET, along with Ethernet is expanded to the metropolitan area network direction, metropolitan area network backbone network in the future may adopt ethernet technology, the problem that may require SDH/SONET how to transmit on Ethernet this moment, the adaptation method that these three kinds of Ethernets and SDH/SONET merge all can not be used for transmitting SDH/SONET on Ethernet.

(3) Wei Lai unified public network will adopt packet-switch technology, adopt above-mentioned three kinds of adaptation methods to be difficult to realize packet-based Dynamic Bandwidth Allocation.

(4) only support point-to-point to connect, upper-layer service is every need carry out a series of processing through a node, can not directly transmit upper-layer service.

(5) the adaptive mode that promptly adopts PPP+HDLC and adopt LAPS for first and second kind, because what HDLC frame and LAPS frame adopted is that specified byte (0X7E) achieve frame is delimited, need carry out transparent processing to the ethernet mac frame, this mode has two defectives, the one, network security problem, if those spiteful people all are set to those specific two bytes (0X7D, 0X7E) to payload information, this doubles with regard to the flow that causes network so, gang up against if adopt, may cause network congestion; In addition, because these two kinds of adaptive modes all do not have error correction, if the frame delimiter byte occurs that wrong (theoretical probability that mistake occurs is 1/2 like this⁸=1/256=0.00390625 promptly is about 3.9/1000ths), just may cause packet loss.

(6) adopt in the network of above-mentioned adaptation method, traditional voice service is what to be separated with the IP network business, can not realization and the compatibility of IP network and packet voice network, and generally believe that now following unified public network should will adopt packet-switch technology, how these adaptation methods are for realizing the voice service packetizing, and the aspects such as the integration of three networks that promote speech, data and video network are without any help.
