Problems solved by technology

[0006] Aiming at the problem in the related art that the broadcast originating node needs to send the message to all other nodes in the overlay network separately when sending the broadcast message, which causes the load of the broadcast originating node to increase, and the same network link repeatedly transmits the sent message during the message sending process , the present invention provides a scheme for joining a new node in an overlay network and a scheme for sending a broadcast message in an overlay network, so as to at least solve the above-mentioned problems

Embodiment 1

[0093] Figure 7 is a schematic diagram of an overlay network according to Embodiment 1 of the present invention, and all nodes in the overlay network are NM nodes. The number of the multicast island where each node is located is determined by configuration or detected, and the nodes in the multicast group with the same number must be located in the same multicast island. A multicast island refers to a continuously deployed network environment that supports IP multicast message sending and receiving, that is, multicast messages sent by nodes in an island can be received by all nodes in the same island that join the multicast group. The nodes shown in 701, 702, and 703 in the figure belong to three multicast islands respectively, and the positions of the nodes in the overlay network have nothing to do with the multicast islands where they are located.

[0094] Figure 8 is a schematic diagram of yet another overlay network according to Embodiment 1 of the present invention, a...

Embodiment 2

[0096] Figure 9 It is a flowchart of a method for NM nodes to join an overlay network according to Embodiment 2 of the present invention, such as Figure 9 As shown, the method may include the following steps (step S902-step S910):

[0097] Step S902, through the manual configuration of the administrator, the joining node obtains the global configuration and local configuration of the overlay network through a request from the boot server, or detection, etc., which should include the node identification; if the joining node is an NM node, the configuration should also include the node user ID. The IP multicast address for sending and receiving routing update messages, the number of the multicast island where the node is located, etc.

[0098] Step S904, if the joining node is an NM node, then bind and configure the specified IP multicast address, join the multicast group, and listen to the relevant ports, and all messages sent to the multicast address can be received subsequ...

Embodiment 3

[0103] Figure 10 is a flowchart of a method for an overlay network node to send a broadcast message in an overlay network according to Embodiment 3 of the present invention, as shown in Figure 10 As shown, the method may include the following steps (step S1002-step S1010):

[0104] Step S1002, when a node needs to send a broadcast message in the overlay network, for example: the node detects that an overlay network adjustment occurs, and needs to send a routing update message to the overlay network;

[0105] Step S1004, the broadcast originating node selects the destination node to send the routing update message according to the node information in the locally stored routing table, and prepares to initiate the routing update broadcast. Specifically, it may include: 1. Group the nodes (NM nodes) capable of sending and receiving IP multicast messages into groups according to their multicast groups, and select a node randomly or according to a certain algorithm from each grou...

Abstract

The invention discloses a method, device and system for sending superimposed network broadcast messages. The method includes: when the first node in the overlay network needs to send a broadcast message to other second nodes in the overlay network, the first node queries the local overlay network routing table to obtain routing information of all second nodes, and the routing information includes: Whether the second node is in a network environment that supports IP multicast, and the IP multicast address of the second node in a network environment that supports IP multicast; the first node determines that it is in the support IP group according to the routing information of the second node The IP multicast group to which the second node in the broadcasting network environment belongs; for the second node belonging to the same IP multicast group, the first node sends a message to the part in the IP multicast group according to the multicast address of the IP multicast group The second node sends a broadcast message, and the part of the second nodes forwards the broadcast message to other second nodes in the IP multicast group. Through the present invention, the node processing load is reduced.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, device and system for sending broadcast messages of an overlay network. Background technique [0002] An overlay network (overlay network) refers to a computer network built on another existing network (for example, an IP (Internet Protocol, Internet Protocol) network). It can be considered that there is a logical connection between two adjacent nodes in the overlay network, that is, the direct connection path between two nodes in the overlay network may correspond to a multi-hop connection at the IP layer, and may correspond to multiple physical connections physically. From the perspective of network structure, overlay networks can be divided into two types: structured and unstructured. The structured overlay network is an organizational method for maintaining the interconnection between nodes on the application layer. It interconnects the nodes in the system accordi...
