Embodiment Construction

[0056] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0057] refer to figure 2 , which shows a flow chart of a message forwarding method according to an embodiment of the present invention. This embodiment may specifically include the following steps:

[0058] Step 101, receiving a message sent by a previous node, where the message includes: forwarding hop count and / or optional node address. It should be noted that, and / or includes the following three situations: (1) the message includes forwarding hops and optional node addresses; (2) the message includes forwarding hops; (3) the message includes optional node addresses.

[0059] The forwarding hop count of the message is used to indicate the number of times the message is forwarded. The initial value of the forwarding hop count i...

Abstract

The invention provides a message forwarding method and device for solving the problems of broadcast loops and broadcast storms in the message forwarding process. The message forwarding method comprises the steps of receiving a message sent from a previous node, distinguishing the type of the message, judging whether the message is forwarded or reaches the maximum forwarding hop when the message is distinguished to be a broadcast message, abandoning the message if the message has been forwarded or has reached the maximum forwarding hop, updating the message if the message is not forwarded and does not reach the maximum forwarding hop, forwarding the updated message to other nodes, judging whether a selectable node address of the message is the address of the current node or whether the message is replied when the message is distinguished to be a unicast message, abandoning the message if the selectable node address of the message is not the address of the current node or the message is replied, and replying the message if the selectable node address of the message is the address of the current node and the message is not replied. The method and device avoid broadcast loops and broadcast storms.

Description

technical field [0001] The invention relates to the technical field of testing, in particular to a message forwarding method and device. Background technique [0002] A broadcast loop is a phenomenon in which packets are continuously transmitted between network nodes but never reach the destination node. When the network topology changes, if the network convergence is slow and uncoordinated or contradictory path selection occurs, nodes will ignore the routes that cannot reach the destination node, which will cause user packets to be sent in a loop and occupy a large amount of network bandwidth. [0003] Combine below figure 1 Describe the broadcast storm, such as figure 1 The shown node S wants to send a message to node F, the middle ABCDE node will forward the same message multiple times, even nodes S and F receive multiple same messages and forward them again, and the entire network nodes are constantly forwarding and repeating packets, resulting in a large occupation o...
