Abstract

The invention discloses a data transmission method based on segmentation by domain in an elastic packet ring network, comprising the steps of: A1, dividing nodes on the elastic packet ring network into different domains by setting domain addresses; B1, uploading a The domain address of the source node is added to the elastic packet ring data packet; C1, the node on the elastic packet ring network receives the elastic packet ring data packet, when the domain address and destination address are respectively the same as the domain address and MAC address of the node. When they are consistent, the current node is determined as the destination node; D1, the destination node removes the domain address to obtain the elastic packet ring data message. The invention utilizes the VLAN function similar to the two-layer Ethernet, realizes the domain segmentation of the RPR ring network from the MAC layer, and limits the communication (broadcast, multicast and unicast) of the data message within a certain domain range. Segmentation has a certain effect of restricting broadcast packets, which can reduce the upper layer's processing burden on irrelevant packets.

Description

technical field [0001] The invention relates to a data packet processing method in an elastic packet ring network, in particular to a data transmission method based on division by domain in an elastic packet ring network. Background technique [0002] RPR (Resilient Packet Ring, Resilient Packet Ring) is a MAC (Media Access Control, Media Access Control) layer protocol, and the position of its layered structure in the OSI reference model is as follows: figure 1 As shown, the RPR layer corresponds to the data link layer, which is further divided into a MAC data path sublayer, a MAC control sublayer and a logical link control sublayer (also known as a MAC client layer). Realize fair algorithm, topology and protection, operation management and maintenance functions in the MAC control sublayer. The MAC data path sublayer communicates with the physical layer through the PHY service interface, and the MAC control sublayer communicates with the link layer through the MAC service i...
