P2P link and sharing link bridging connection system and method thereof

Abstract

The invention discloses a bridge connection system of a point-to-point link and a shared link, comprising one or a plurality of remote devices and one or a plurality of computers, wherein, the system also comprises a bridge connection device which realizes the connection of the point-to-point link by a transmission facility and the remote device and realizes the connection of the shared link by an Ethernet and the computer. The invention also discloses a method for bridging the point-to-point link and the shared link. The invention and the bridge connection device of the point-to-point link and the shared link realize the safe and reliable transmission of the IP protocol between the remote device on the point-to-point link and the computer on the shared link, effectively use the prior E1 / T1 point-to-point link resources and lower the maintenance and investment cost.

Description

technical field [0001] The invention relates to the field of computer network communication, more specifically, to a bridging device for Internet protocol forwarding between a point-to-point link and a shared link and a method for realizing Internet protocol forwarding based on this. Background technique [0002] Integrated access equipment (Multi-Service Access Node, MSAN) and integrated access gateway (Multi-Service Access Gate, MSAG) are next-generation access network equipment that provide voice services and data services at the same time, and their network management is usually based on Internet Protocol (Internet Protocol, IP) standard Simple Network Management Protocol (SNMP), traditional access network equipment is a pure voice service system, and its network management is often based on non-standard custom protocols. [0003] Because the traditional pure voice service access equipment and the MSAN / MSAG network management protocol are not unified, usually do not supp...

AI Technical Summary

Problems solved by technology

[0005] Data services are mainly based on Ethernet, and network management mainly adopts Simple Network Management Protocol. Simple Network Management Protocol information and data service information are usually transmitted on the same Ethernet. As we all know, Ethernet based on shared media is vulnerable to virus infection or malicious attacks, so that the security of network management information cannot be effectively guaranteed

In addition, it is necessary to assign a public Media Access Control (MAC) address to each remote device on the Ethernet. Since telecommunication devices usually have two boards, the main board and the backup board, the assignment and management of the master board and the backup board The MAC address of the board increases the complexity of management and maintenance

[0006] If the network management protocol information and broadband service information are isolated in two independent Ethernet networks, although the security of the network management protocol information can be guaranteed, laying two independent Ethernet networks will greatly increase the investment cost of equipment
