Timing transmission packet method and packet transmission module

Abstract

The method includes steps: placing the pointer to a list item (LI) of message list (ML) to be sent, and considering address of LI as resetting address of the pointer; when detecting that unit time of timer is arrived, the method determines whether to send out message corresponding to LI based on current timing value (CTV), and option of LI the pointer points to (PLIPP); placing the pointer to next LI, and determining whether the value of pointer is larger than length of ML to be sent; if yes, then placing the pointer to first LI of ML to be sent, and gong to step (1): detecting whether unit time of timer is arrived; otherwise, going to step (2): determining whether to send the message corresponding to LI the pointer points to based on CTV of the timer, and PLIPP. The invention also discloses a module for sending out message. The invention can smooth paroxysmal flux in network at same time, reduce rate of losing packets, and raise performance of system.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for regularly sending messages and a message sending module. Background technique [0002] Ethernet technology is easy to use, low in price, and its bandwidth is constantly increasing. Whether it is a business or a network structure, it has been widely used in enterprise networks, metropolitan area networks, and wide area networks. However, traditional Ethernet can maintain , The operability is relatively weak. As the scope of Ethernet promotion continues to expand, the functional requirements for Ethernet operation / management / maintenance (Operation, Administration, and Maintenance, OAM) are also becoming stronger. [0003] Ethernet OAM can be divided into two parts: fault management and performance management. Among them, the fault management is to send detection packets to detect the connectivity of the network through timing or manual triggering. [0004] In the implementa...

Problems solved by technology

In the process of implementing the present invention, the inventor found that in the prior art, when the number of entries (generally 2k or 4k) is large, there will be many messages with the same fixed length, which will cause burst traffic. The formation of instantaneous flow imbalance will affect the normal business flow, such as: may cause packet loss, etc.
