Problems solved by technology

[0008] The technical problem to be solved by the present invention is to provide a method and system for improving the performance of SSCOP sending data, which is used to solve the problem of wasting bandwidth due to the delay in updating the sending window at the sending end and causing the data waiting to be sent by the sending end to not be sent in time

Embodiment Construction

[0035] The specific implementation manner of this solution will be further described in detail below in conjunction with the accompanying drawings.

[0036] Fig. 1 is the schematic flow chart of the method for improving SSCOP transmission data performance of the present invention, and this flow process specifically comprises the following steps:

[0037] Step 100, setting two network elements as network element 1 and network element 2 respectively, and using the SSCOP protocol for data transmission;

[0038] Step 101, the SSCOP protocol entity of network element 1 receives a request for sending data from the application layer, and then adds the requested data to the sending queue;

[0039] Step 102, the SSCOP protocol entity checks the sending window size, and judges whether the sending window size has reached the maximum sending window boundary given by the receiving end, if it has reached, then proceed to step 103; otherwise directly carry out data transmission, and proceed ...

Abstract

The invention discloses a method which improves SSCOP data transmission property and the system thereof. The method includes: step (1), establish the data transmission link between the data sending side and the data receiving side by SSCOP protocol; step (2), the data sending side sends data to the data receiving side and when the sending window size reaches maximum boundary of the data receiving side, probe the stage of data receiving side window state and send state request message to the data receiving side within the POLL timer period set on the stage; step (3), the data receiving side receives the state request message and returns the response message to the data sending side, which will send data to the data receiving side according to response message. The invention can reflect the update of the receiving window on the receiving side to the data sending side as soon as possible and improve the data transmission capacity of the link finally.

Description

technical field [0001] The present invention relates to ATM (Asynchronous Transfer Mode, asynchronous transfer mode) transmission method and system, particularly relate to a kind of when adopting SSCOP protocol to carry out data transmission on AAL5 (ATM Adaptation Layer Type 5, ATM Adaptation Layer Type 5) to improve SSCOP sending Method and system for data performance. Background technique [0002] SSCOP (Service Specific Connection Oriented Protocol, Service Specific Connection Oriented Protocol) The sender sends data is limited by the send window. The sending window size of the sending end is changed by the receiving end notification. At present, the sender of SSCOP has three methods to update the send window size of the local end. [0003] 1) In the process of sending data, SSCOP will periodically send POLL (status request) packets to query the status of the peer receiving data when the timer expires. After receiving the POLL packets, the peer will respond with STAT (...
