Problems solved by technology

[0006] (1) The port bandwidth buffer capacity of the receiving device is limited, and too many repeated simulation packets occupy limited bandwidth resources
[0007] (2) The data volume of repeated simulation messages is too large, resulting in some beneficial simulation messages that can only be discarded
[0008] (3) A great burden on the work of the device CPU

Embodiment Construction

[0050] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0051] like figure 2As shown, it is a schematic diagram of a network for transmitting simulation packets in an MPLS network according to an embodiment of the present invention. The simulation packets enter the MPLS network at the access side and are transmitted in the MPLS network. The MPLS transmission network is a narrowband transmission network. It should be noted that the method for detecting repeated emulation messages in the present invention needs to enable the pseudowire (PW) control word function on the system equipment, and the serial number in the pseudowire control word is defined by the standard rather than customized.

[0052] like image 3 As shown, a method for detecting repeated emulation packets includes:

[0053] Step S100, obt...

Abstract

The invention provides a method and device for detecting repeated simulation messages. The method comprises that a first simulation message received in a first period and a second simulation message received in a second period are obtained; a serial number field value in a pseudo-line control word of the first simulation message and a serial number field value in a pseudo-line control word of the second simulation message are detected; and the serial number field value in the pseudo-line control word of the first simulation message is compared with the serial number field value in the pseudo-line control word of the second simulation message, and when the second simulation message includes the serial number field value the same with that of the first simulation message, it is determined that the second simulation message includes the simulation message which repeats at least part of the first simulation message. Thus, repeated simulation messages transmitted in the network environment are detected, the detected repeated simulation messages are deleted, and the network reliability is improved greatly.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for detecting repeated simulation messages. Background technique [0002] Today's society is an information society. The highly developed information society requires that the communication network can provide a variety of telecommunication services, and the amount of information transmitted, exchanged and processed through the communication network will continue to increase. development in the direction of automation, intelligence and personalization. [0003] The transmission system is an important part of the communication network, and the quality of the transmission system directly restricts the development of the communication network. One of the key points of the current information highways developed by countries all over the world is to build a large-capacity transmission optical fiber network, continuously increase the signal rate on the trans...
