Problems solved by technology

If the physical interfaces on both sides of the RPR site are down (down), the site becomes an isolated node isolated from the RPR ring. Therefore, RPR cannot protect the traffic going out of this node.

Embodiment Construction

[0038] An embodiment of the present invention will now be described in detail, Figure 5 with Image 6 A flowchart of these embodiments is shown.

[0039] The main implementation method of the present invention is, through the broadcast of the site attribute discovery (ATD) control frame of regular broadcast, utilize the virtual MAC address of VRRP carried by the Secondary MAC ATT in this ATD frame, let all nodes on the ring all be able to know VRRP The position of the group master device, the traffic sent to the virtual IP address of the VRRP group is only sent to the VRRP group master device, and this change can be sensed in time after the VRRP master / standby switchover, so as to avoid broadcast methods such as foolding.

[0040] Figure 5 A flowchart of a method for implementing a VRRP redundancy protocol in a resilient packet ring according to an embodiment of the present invention. from Figure 5 It can be seen that when the VRRP-configured site becomes the master dev...

Abstract

The method includes following steps: virtual MAC address load-bearing redundant router protocol on Secondary MAC ATT of ATD control frame is found at site attribute; informing all sites on the ring the location of main device in redundant router protocol group; the flow unicast of the virtual MAC in redundant router protocol group is sent to main device in redundant router protocol group. The invention can support application of VRRP protocol, provide protection for redundant device, effectively utilize bandwidth, and avoid mass broadcast flow in application of VRRP.

Description

technical field [0001] The invention relates to an elastic grouping ring, in particular to a method for realizing redundant router protocol on the elastic grouping ring. Background technique [0002] Resilient Packet Ring (RPR) is a new medium access control (MAC) layer technology being standardized by the IEEE 802.17 working group. It is a MAC protocol working on the second layer of the OSI (Open Systems Interconnection) protocol stack. It has nothing to do with the physical layer and can run on Synchronous Optical Network / Synchronous Digital Hierarchy (SONET / SDH), Ethernet (Ethernet) and Dense Wavelength Division Multiplexing (WDM). RPR technology absorbs the economy of Gigabit Ethernet, SDH's carrier-class features and Ethernet's data service-oriented high-bandwidth distribution, flexibility, scalability, and high reliability of APS fault self-healing. RPR Not only support IP business, but also support traditional TDM business. RPR will be used to replace SDH to build a...
