Embodiment Construction

[0020] exist figure 1 , shows TCP / IP message processing.

[0021] The process receives messages from multiple sources via a communication network operating using the TCP protocol.

[0022] Sockets SC are associated with each source and are individually labeled SC1, SC2 and SC3.

[0023] Each socket SC includes a receive list RX listing the buffer stores SKB containing received data.

[0024] Each socket also includes a send list (not shown), which lists buffers containing data streams to be sent.

[0025] exist figure 2 In, the receive list RX is structured such that each buffer store SKB includes a "previous" pointer PP for indicating the buffer store SKB preceding the current buffer store in the corresponding list and a "previous" pointer PP for indicating the buffer store SKB preceding the current buffer store in the corresponding list The second "next" pointer to the buffer memory following the buffer memory.

[0026] For selected sockets, buffer memories are linked ...

Abstract

The invention relates to a method and a device for communication between several connection interfaces, wherein one (SC3) of the connection interfaces (SC) is designated able to receive the stream of data received by each connection interface associated with a chosen process. Said connection interface thus designated (SC3) furthermore comprises a supplementary reception-list (RXS) cataloguing buffer memories containing the stream of data received by the set of connection interfaces participating in a chosen process. The buffer memories (SKB) of each connection interface (SC1, SC2, SC3) belong at the same time to two reception lists (RX1, RXS) and each furthermore comprise a supplementary preceding-pointer indicating the buffer memory which precedes the current buffer memory in the supplementary reception-list (RXS) and a supplementary following-pointer indicating the buffer memory which follows the current buffer memory in the supplementary reception list (RXS), thereby making it possible to access the stream of data received by the set of connection interfaces participating in said process, in the order of arrival of said stream of data received.

Description

technical field [0001] The present invention relates to communication between multiple sockets within a communication network, which is applicable to processes that receive messages or data from multiple sources over an Internet communication network and operate using a protocol such as TCP (Transmission Control Protocol). Background technique [0002] Typically, a socket includes a receive list for listing buffers containing streams received and a send list for listing buffers containing streams to be transmitted. [0003] The receive list and the send list are said to be "doubly linked" because each of the buffer memories constituting the receive list and the send list has a "previous A structure of a "pointer" and a second "next" pointer for indicating the buffer memory following the current buffer memory in the corresponding list. [0004] Using only one socket, the process can receive messages or data while waiting for them to arrive on said socket's receive list. [...
