Embodiment Construction

[0052] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments . Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0053] The embodiment of the present invention provides a kind of message transmission method, comprising: when needing to send flow control transmission protocol SCTP protocol handshake message, judge whether there is any IP inconsistent with the IP in the out-of-band IP pool in the local IP list; If there is an IP inconsistent with the IP in the out-of-band IP pool in the machine IP list, add the IP inconsistent with the IP in the out-of-...

Abstract

The invention discloses a message transmission method and device and relates to the field of SCTP network application. The method is characterized by, when a handshake message of a stream control transmission protocol (SCTP) needs to be sent, judging whether a local internet protocol list has IPs not same with IPs in an out-of-band IP pool; if the local internet protocol list has the IPs not same with the IPs in the out-of-band IP pool, adding the inconsistent IPs to the handshake message; and after all of the IPs, not same with the IPs in the out-of-band IP pool, in the local internet protocol list are added to the handshake message, sending the handshake message. The message transmission method and device guarantee normal connection of links, and solve the problem that in the prior art, when a plurality of devices are connected to one server in a distributed networking environment, connection of a plurality of multi-homed hosts is refused due to having the same internal debugging IP.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a message transmission method and device. Background technique [0002] SCTP (StreamControlTransmissionProtocol, Stream Control Transmission Protocol) is a connection-oriented stream transmission protocol, which can provide stable and orderly data transmission services between two endpoints. SCTP is an extension and improvement of TCP (Transmission Control Protocol, Transmission Control Protocol), which inherits the congestion control mechanism of TCP; the biggest difference between SCTP and TCP is that SCTP supports multi-homing and multi-flow. Supporting multi-homing is an important feature of SCTP. When a device at one end of an SCTP link has multiple IP (Internet Protocol, Internet Protocol) addresses available for data transmission, the device is considered to be multi-homing. One of the IP addresses is used as the main transmission channel. By default, data will be sent ...
