Method, apparatus and system for sending message

Abstract

The present invention discloses a method, an apparatus and a system for sending a message, belonging to the field of network transmission. The method comprises: receiving a message and acquiring a message keyword used to identify the message from the message; acquiring a message eigenvalue corresponding with the message keyword; acquiring an egress port from a port mapping relationship list according to the message eigenvalue, wherein the port mapping relationship list include the mapping relationship between the range of the message eigenvalue and the egress port; sending the message via the acquired egress port. The apparatus includes a receiving module, a message keyword acquiring module, an eigenvalue acquiring module, a egress port acquiring module and a sending module. With the method, the apparatus and the system for sending a message, the phenomenon of imbalance flow caused by acquiring an egress port based on port numbers and message eigenvalues in the prior art can be prevented, a bandwidth utilization rate of an aggregate group is improved, and the consistency among egress ports is ensured.

Description

technical field [0001] The invention relates to the field of network transmission, in particular to a method, device and system for sending messages. Background technique [0002] Link aggregation is a technology that treats multiple physical links (such as electrical ports, optical ports, etc.) as a single logical connection. It allows two switches to transmit data simultaneously through multiple links in parallel to provide more High bandwidth, greater throughput and recoverable technology. A link aggregation may include multiple physical links. When the packet egress is a link aggregation, the egress selection of multiple links is involved. [0003] At present, the HASH method is generally used to establish the mapping relationship between the message keyword set and the HASH index value, and the final physical outbound port is obtained according to the HASH index value and the number of ports, so that the same flow is mapped to a fixed outbound port. Port selection met...

Problems solved by technology

[0005] When the modulo values ​​of multiple different HASH index values ​​(such as 0x1fe, 0x456) are the same, the corresponding outgoing ports are the same, which means that different packet flows will select the same outgoing port at the same time. In this case, the traffic between the ports will be unbalanced, so that the effective bandwidth of the aggregation group cannot be fully utilized, and when the online status of the member ports in the aggregation group changes, the value after the modulo of the packets of the same flow may be caused different, there is no guarantee of egress selection consistency for streams
