Problems solved by technology

[0006] It can be seen that the technical solution adopted at present is that the Ethernet private line service is sent in the form of broadcast in the RPR ring network, and the realization of the EVPL function is completed by the Ethernet layer. In this way, on the one hand, the Ethernet virtual private line service is The path and bandwidth on the RPR ring cannot be fixedly allocated, resulting in a huge waste of network bandwidth. On the other hand, the use of broadcasting to send virtual private line services makes the security of service transmission unable to be guaranteed, so it cannot reflect the private line. Advantages of business safety and reliability

Embodiment Construction

[0040] The core idea of ​​the present invention is to transmit the Ethernet virtual private line service based on MPLS technology in the RPR ring network, so that the Ethernet virtual private line service can still be transmitted on a certain path with a certain bandwidth on the RPR ring network, thereby ensuring that the Ethernet It ensures the security and reliability of virtual private line services transmitted in the RPR ring network, and can effectively utilize network bandwidth resources.

[0041] The present invention performs MPLS encapsulation processing on the Ethernet message before the Ethernet service on the RPR ring, and then establishes a label switching path on the Ethernet and the RPR ring network, through which the EVPL service is transmitted on the RPR ring network. In the present invention, for the LSP of the Ethernet service on the RPR ring, not only need to determine its ingress port, egress port and MPLS label, but also determine the MAC address of the pu...

Abstract

The invention relates to realization method and system for transmitting Ethernet affair in RPR net. When receives Ethernet affair waiting for transmission, RPR net transmits affair based on MPLS protocol. This invention realizes to transmit private line Ethernet affair still in RPR net, which ensures well security of private line affair during transmission, and exhibits the advantage of safety and credibility in private line; meantime, as soon as determination for transmission route and bandwidth of Ethernet affair in RPR net, also ensures utilization efficiency of network bandwidth of transmission network.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method and a system for realizing Ethernet service transmission on an RPR network. Background technique [0002] RPR (Resilient Packet Ring) technology is an emerging data transmission technology, which can add a layer of ring service management between the physical layer {such as SDH (Synchronous Digital Hierarchy)} and data equipment. Through this loop service management layer, functions such as space reuse, fair access, intelligent switching, and path optimization can be realized. The RPR technology improves the traditional IP over SDH (IP based on synchronous digital sequence) networking mode, realizes the fair statistical multiplexing of the ring network bandwidth, and provides a relatively complete protection switching mechanism. Therefore, the RPR described above The technology can be applied to the business transmission of efficient bandwidth utilization ...
