Method, terminal port and system for packet transmission

Abstract

The embodiment of the invention discloses a method, a port and a system for transmitting messages, which belong to the communication field, wherein the method comprises assigning a relevant serial number for each message in a plurality of messages, adding the serial number to relevant messages, sending the messages, wherein the serial number is used to receive the sequencing of the port to a plurality of messages. A sending port comprises a dispatching module and a sending module. A receiving port comprises a receiving module and a sequencing module. The system comprises a sending device and a receiving device. The invention enables a receiving end to sequence for a plurality of messages according to the serial number of each message through assigning a relevant serial number for each message in a plurality of messages, and guarantees the sequential consistency of a plurality of messages in end-to-end transmission.

Description

technical field [0001] The invention relates to the communication field, in particular to a method, port and system for transmitting messages. Background technique [0002] In recent years, with the rapid development of enterprise data communication services and related fusion services, Ethernet switches, as indispensable key equipment, have not only greatly improved in quantity, but also have been continuously improved in terms of quality and performance. . Speed ​​is the main indicator of network performance. From 10M to 100M and then to Gigabit, Ethernet transmission bandwidth is constantly increasing, but due to the rapid growth of data traffic, Gigabit bandwidth cannot meet the high demand between switches or between switches. Therefore, link aggregation technology that uses multiple physical links as a logical link appears. Through the link aggregation technology, multiple Ethernet physical links can be simulated as a virtual aggregation port through static binding o...

Problems solved by technology

[0007] 1) In the first method of the prior art, multiple messages are transmitted to the opposite end through different physical links of the aggregation port, and the congestion levels of different physical links are different. If multiple messages pass through different physical links of the aggregation port When the physical link is transmitted to the opposite end, it is inevitable that the multiple packets received by the opposite end are in the same order as the multiple packets received by the sending end.

[0008] 2) The second method of the prior art requires business flow matching at first, but there is no unified business flow matching method at present; in addition, the length difference of multiple messages of different business flows can reach 20 to 30 times at most, Transmission is carried out at the granularity of business flow, and the bandwidth between different physical links is prone to imbalance, resulting in a decrease in the utilization of physical links
