Problems solved by technology

[0014] As shown in Figure 5, when using RPR dual-board positions to enhance the reliability of the RPR ring network and prevent the failure of the entire network caused by single-board failures, the RPR protocol must be distributed to span two single-boards, so that the corresponding protocol The implementation complexity is high
At the same time, two RPR boards are interconnected through a pairing (mate) interface, because the pairing interface itself may fail, which will increase the unreliability of the corresponding RPR ring network
In addition, for the system shown in Figure 5, since the system performance depends on the perception of single board faults, it is difficult to guarantee stable system performance

Embodiment Construction

[0040] Based on the specification description and the consideration of easy reading, the terms appearing in the patent application documents of the present invention are defined one by one as follows:

[0041] The RPR (Resilient Packet Ring, Resilient Packet Ring) ring network is a network with a reciprocal double-ring topology, and one RPR ring network includes at least two RPR sites.

[0042] The RPR logical ring is a complete double-ring ring data transmission link in the RPR ring network, and the so-called double ring specifically includes a physical ring 0 for clockwise data transmission and a physical ring 1 for counterclockwise data transmission.

[0043] The RPR logical interface is the logical interface used to access the RPR logical ring on the RPR site; and corresponds to the double-ring structure of the RPR logical ring. An RPR logical interface includes two physical interfaces, which are used to access the corresponding physical 0 ring and physics 1 ring.

Abstract

The method comprises: setting n (n larger than 2) RPR logical ports on each site in RPR ring network, which are used for respectively accessing n RPR logical rings being independently each other; balancing the traffic load on n RPR logical ports by making the link aggregation for n RPR logical ports on said each site, and making link switch when said any PRP logical port on said any site failures. The invention also reveals an apparatus used for creating RPR ring network and RPR sites, which comprises n RPR logical ports and a link aggregation unit.

Description

technical field [0001] The present invention relates to a metropolitan area network, in particular to RPR (Resilient Packet Ring, Resilient Packet Ring) networking technology in the metropolitan area network. More specifically, the present invention relates to a method for establishing a reliable RPR ring network, and related RPR site equipment used to establish the reliable RPR ring network. Background technique [0002] RPR (Resilient Packet Ring) technology integrates the intellectualization of IP (Internet Protocol, Internet Protocol) network, the economy of Ethernet, and the high bandwidth efficiency and reliability of optical fiber ring network. Network operators provide a flexible and efficient networking solution. The RPR technology makes it possible for operators to provide carrier-class services at low cost in the metropolitan area network, and reduces transmission costs while providing SDH (Synchronous Digital Hierarchy, Synchronous Digital Hierarchy)-level netwo...
