Abstract
The present disclosure discloses an SCTP-based communications method and system, and an apparatus. The method includes: A network element selector receives an SCTP packet that includes a plurality of SCTP data chunks of a plurality of user terminals. Because each SCTP data chunk carries index information, the network element selector may select a service providing device for each user terminal based on the index information carried in each SCTP data chunk. Therefore, application layer messages of different user terminals in the SCTP may be routed to different servers based on LBI parameters, and corresponding session persistence is implemented in a subsequent interaction process.

A Stream Control Transmission Protocol (SCTP)-based communications method, comprising:
- receiving, by a network element selector, an SCTP packet, wherein the SCTP packet comprises a plurality of SCTP data chunks of a plurality of user terminals, and each SCTP data chunk carries index information;
- and
- selecting, by the network element selector, a service providing device for each user terminal based on the index information carried in each SCTP data chunk, wherein selecting, by the network element selector, a service providing device for each user terminal based on the index information carried in each SCTP data chunk comprises:
- when index information carried in a first SCTP data chunk sent by a first user terminal in the plurality of user terminals has a first value, selecting, by the network element selector for the first user terminal based on network load statuses of a plurality of service providing devices, a first device in the plurality of service providing devices to serve as the service providing device.
An apparatus, comprising:
- a receiver, the receiver configured to receive a Stream Control Transmission Protocol (SCTP) packet, wherein the SCTP packet comprises a plurality of SCTP data chunks of a plurality of user terminals, and wherein each SCTP data chunk carries index information;
- and
- at least one processor, the at least one processor configured to select a service providing device for each user terminal based on the index information carried in each SCTP data chunk, wherein when index information carried in a first SCTP data chunk sent by a first user terminal in the plurality of user terminals has a first value, the at least one processor is configured to select, for the first user terminal based on network load statuses of a plurality of service providing devices, a first device in the plurality of service providing devices to serve as the service providing device.
A Stream Control Transmission Protocol (SCTP)-based communications system, comprising:
- a plurality of service providing devices;
- and
- a network element selector separately connected to the plurality of service providing devices and configured to:
- receive an SCTP packet, wherein the SCTP packet comprises a plurality of SCTP data chunks of a plurality of user terminals, and each SCTP data chunk carries index information, and
- select a service providing device for each user terminal from the plurality of service providing devices based on the index information carried in each SCTP data chunk, wherein when index information carried in a first SCTP data chunk sent by a first user terminal in the plurality of user terminals has a first value, the network element selector is configured to select, for the first user terminal based on network load statuses of the plurality of service providing devices, a first device in the plurality of service providing devices to serve as the service providing device.
