Problems solved by technology

[0012] 1. The transmission method of IPoA requires that the IP header contained in the IP data packet and the TCP / UDP header in the IP packet data content (if carrying these two protocol messages) also need to be transmitted on the ATM network, which reduces the network cost. Utilization of
[0013] 2. The IPoA transmission method needs to increase the decomposition of IP datagrams into ATM cells and the framing process of ATM cells into IP datagrams at both the source and destination, which greatly reduces the processing rate of datagrams. Data streams with high real-time requirements, such as business and voice data streams encapsulated in UDP data packets, obviously cannot meet the requirements

Embodiment 1

[0033] The embodiment of the present invention provides a system for exchanging data between an ATM network and an IP network. As shown in Figure 5, described system comprises ATM network and IP network, wherein, also comprises a data processing unit, and this data processing unit is set up at the boundary place of ATM network and IP network, is used for the ATM data packet or Analyzing the IP data packet and performing data packet type conversion on the data packet requiring route conversion, and sending the converted data packet to the IP network or the ATM network; wherein, the IP data packet is an IP data packet encapsulating UDP.

[0034] In this embodiment, the data processing unit at least includes a data conversion unit 501, an IP side processing unit 503, and an AAL side processing unit 504; wherein,

[0035] The IP side processing unit 503 receives the IP data packet sent by the IP network, and directly analyzes the IP data packet and sends it to the data conversion ...

Embodiment 2

[0059] The embodiment of the present invention provides a method for exchanging data between an ATM network and an IP network. The method for realizing data exchange between the ATM network and the IP network will be described in detail below by taking the system of Embodiment 1 as an example.

[0060] As shown in Figure 5, the method includes the steps: the ATM network or the IP network sends the ATM data packet or the IP data packet to the data processing unit set up at the boundary of the ATM network and the IP network, wherein the IP data packet is a UDP After receiving the ATM data packet or IP data packet, the data processing unit analyzes the ATM data packet or IP data packet and performs data packet type conversion on the data packet that needs to be converted, so as to realize the ATM cell and IP data packet exchange between packages. Then, the data processing unit sends the converted data to the IP network or the ATM network.

[0061] In this embodiment, analyzing ...

Abstract

A method for exchanging data of ATM network to IP network includes send ATM or IP data packet to data processing unit set at boundary of ATM network and IP network, setting IP data packet to be IP data packet carried with UDP, carrying out analysis on ATM or IP data packet and carrying out data packet type conversion for data packet requiring route conversion by sad data processing unit for realizing exchange between ATM signaling and IP data packet.

Description

technical field [0001] The invention relates to data exchange and transmission technology, in particular to a method and system for data exchange between an ATM (Asynchronous Transfer Mode; asynchronous transfer mode) network and an IP network. Background technique [0002] ATM protocol and IP protocol are two different protocol formats. The ATM protocol is implemented using ATM switching technology, which is a fast packet switching technology, and the length of the packet is fixed at 53 bytes, called ATM cells. As shown in FIG. 2, it is a schematic diagram of an ATM cell format. ATM cells contain 5 bytes of header information and 48 bytes of payload information. In the header information, it contains the VPI and VCI information marking the ATM address and some other marking contents. [0003] The ATM protocol layer is divided into the physical layer, the ATM layer and the ATM adaptation layer (AAL: ATMAdapter Layer) layer from bottom to top, and the application layer on ...
