Method and device for realizing data package transmission on synchronous digital system

Abstract

The unit is composed of POS-PHY level 12 and MII interface switching module and Ethernet interface network processor module. The method is at the follows: 1) PPP data frame transmitted from POS physical layer chip is converted to be Ethernet frame by interface switching module; 2. Ethernet frame from the interface module is processed by the Ethernet interface network processor to divide it into cell net charge and to regenerate cell head being sent to exchange net according to processed packet address; 3 the cell stream from exchange net is reorganized for packet by the Ethernet processor andthen to send it to the interface module; and 4. Ethernet data packet is converted to PPP data frame by the interface switching module and to send it to POS physical layer.

Description

technical field [0001] The invention belongs to methods and devices of network processors in communication technology, in particular to interface methods and devices for broadband data access products. Background technique [0002] Since the 1990s, the Internet has achieved tremendous development, and the number of users has grown explosively. Since 1989, the number of hosts on the Internet has doubled approximately every 56 weeks. In the past three years, the number of WEB servers on the Internet has almost doubled every 23 weeks, and this growth is exponentially doubling. With the advancement of communication technology and the drive of market demand, the voice services transmitted by the traditional telephone network and the video services transmitted by the cable TV network are gradually transferred to the computer network in the form of packets, such as IP Phone, VOD and so on. With the sharp increase in the number of users, the bott...
