Problems solved by technology

[0004] In order to solve the problem that the L2TP control concurrent processing method in the prior art is at the back end of the protocol process processing, the request processing exceeding the concurrent processing performance causes resource waste and affects the concurrent processing efficiency of the LNS device, and provides a method in front of L2TP forwarding End identification processing, reducing the impact of packets that exceed the concurrent processing performance of the L2TP control plane on the L2TP control plane

Embodiment Construction

[0026] In order to make the technical solution of the present invention clearer, the present invention will be described in further detail in conjunction with the accompanying drawings:

[0027] An embodiment of the present invention provides a concurrency control method, which uses a virtual input queue to queue all tunnel or session request messages to implement concurrency control on an LNS device. The application scenario of the embodiment of the present invention includes multiple LAC devices and one LNS device, such as figure 1 As shown, the specific implementation steps of the method include:

[0028] S101. Create a virtual input queue, and set the queue length of the virtual input queue to the maximum number of concurrent request packets that can be processed by the L2TP control plane of the LNS device; and the queue length of the virtual input queue can be modified. The request message includes opening a control connection request SCCRQ (Start Control Connection Requ...

Abstract

The invention discloses a concurrency control method. The specific implementation of the method includes: creating a virtual input queue and setting its queue length; identifying the SCCRQ message or ICRQ message from the messages received by the L2TP forwarding plane of the LNS device. text; judging whether the quantity of SCCRQ message and ICRQ message in the virtual input queue reaches the queue length of the virtual input queue at this moment, if the quantity of the SCCRQ message and the ICRQ message in the virtual input queue does not reach the virtual input queue at this time queue length of the queue, enqueue the SCCRQ message or ICRQ message to the virtual input queue. The present invention also provides a concurrency control device. The beneficial effects of the present invention are: the present invention uses a virtual input queue mechanism to enable SCCRQ messages or ICRQ messages to enter the virtual input queue on the L2TP forwarding plane of the LNS device, avoiding exceeding the L2TP Packets with concurrent processing performance on the control plane impact the L2TP control plane, reducing the load on the L2TP control plane and improving the concurrent processing efficiency of the LNS device.

Description

technical field [0001] The invention belongs to the field of data communication, and in particular relates to a concurrency control method and device. Background technique [0002] With the development of data communication technology, the Layer 2 Tunneling Protocol (Layer 2 Tunneling Protocol, L2TP for short) is widely used and recognized, especially with the arrival of the third generation mobile communication technology, the L2TP protocol has been more widely used. In view of this, customers pay more attention to the usage characteristics of L2TP access to L2TP Access Concentrator (LAC) and L2TP Network Server (L2TP Network Serer, LNS). In practical applications, multiple LACs or dial-up The client corresponds to an LNS device, so the performance requirements for the LNS device to handle concurrent connections are higher, because this involves the convergence of the L2TP protocol control of the LNS device in the case of large concurrent connections. [0003] At present, ...
