Problems solved by technology

In this way, limiting the entire RPR to the broadcast domain will cause some nodes in the RPR to receive broadcast packets or unknown packets that have nothing to do with their own business needs, which will waste the bandwidth in the RPR

Embodiment Construction

[0025] In this application, the entire RPR is no longer limited to be a broadcast domain, but the broadcast domain is set according to actual service requirements.

[0026] As an embodiment, in this application, when setting the broadcast domain according to actual business needs, you can refer to the service domain to which each node belongs, so that the message is only effectively broadcast in the service domain to which it belongs, rather than broadcast in the entire RPR, which can avoid A large number of packets are flooded in the RPR broadcast to maximize the utilization of RPR bandwidth.

[0027] In this application, the service domain to which each node belongs can be realized through configuration. Seen from the business level, the business domain here is equivalent to a logically independent business ring (also called logical business ring). Nodes on the RPR can belong to multiple different service domains at the same time. Preferably, in this application, the entir...

Abstract

The present application provides a message broadcasting method and device applied in a resilient packet ring (RPR). This application does not broadcast the message in the entire RPR when broadcasting the message, but first determines the broadcast mode of the message in the RPR according to the topology information of the first service domain corresponding to the first service domain to which the message belongs. The broadcast mode in the RPR is determined depending on the topology information of the first service domain corresponding to the first service domain to which the message belongs, which makes this application finally broadcast the message in the RPR according to the broadcast mode, and the message can be limited to the RPR in the The nodes in the first service domain broadcast among the nodes, realizing effective broadcasting of messages only in the service domain to which they belong, reducing the broadcast domain of messages, avoiding the flooding of a large number of messages in RPR broadcasting, and maximizing the utilization rate of RPR bandwidth.

Description

technical field [0001] The present application relates to network communication technology, in particular to a message broadcasting method and device applied in a resilient packet ring (RPR: Resilient PacketRing). Background technique [0002] RPR is a new type of media access control (MAC: Media Access Control) protocol, which can run on synchronous optical network (SONET: Synchronous Optical Network) / synchronous digital series (SDH: Synchronous Digital Hierarchy), dense wavelength division multiplexing (DWDM: Dense Wavelength Division Multiplexing) and Ethernet, providing flexible and efficient networking solutions for broadband IP MAN operators. [0003] RPR adopts a reverse double ring structure. The so-called reverse double-ring structure refers to ring 0 (also called Outer Ring (outer ring)) in the clockwise direction, and ring 1 (also called Inner Ring (inner ring)) in the counterclockwise direction. figure 1 The reverse bicyclic structure of RPR is shown. [000...
