Problems solved by technology

[0008] The invention mainly solves the problem that the time stamps are easily reversed and out of order when the data packets collected by the multi-service board (more than 2 kinds of services) collection machine in the field of signaling collection are sent to the upper-layer processing system
The solution of the present invention can solve the hidden trouble caused by the physical loopback of the master-slave boards for the time stamp synchronization of data packets, and the synchronization mechanism between different types of boards is inconsistent, so it is impossible to ensure that all different types of business boards are sent to the upper analysis system. Packets are in order problem

Embodiment Construction

[0031] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0032]Boards with various types of services are plugged in, and a method is required to solve the problem of reverse and out-of-order timestamps, and at the same time avoid the possibility of physical line loopback connections increasing the hidden dangers of failure points. This program has been implemented on the company's SuperCAP-E that can insert 12 boards, and the effect is good.

[0033] The structural diagram of this technical solution can be found in figure 1 .

[0034] In the present invention, the multi-service signaling collecting board data packet sorting device is composed of a boar...

Abstract

The invention provides a multi-service signaling collection board data packet sorting method and device, which are used to correctly process the order in which data packets collected by a multi-service board collection machine are sent to an upper-layer processing system. The multi-service signaling acquisition board data packet sorting device is composed of a board target module and a computer host module, and the board target module and the computer host module cooperate to operate; the board target module is composed of multiple board links, each The board link includes an FPGA module and a buffer buffer module for storing packets; the computer host module is composed of multiple buffer modules, and each buffer module corresponds to a board link.

Description

technical field [0001] The invention relates to the field of signaling transmission, in particular to the correct timing processing when the data packets collected by multi-service boards (more than 2 kinds of services) in the field of signaling collection are sent to an upper-layer processing system. Background technique [0002] In the field of data collection, with the diversification of application services, different signaling protocols will be used between network elements, such as HDLC protocol, ATM protocol, IMA protocol, and TCP / IP protocol. Moreover, the data traffic varies among different network elements. Some use PCM 2M transmission, some use optical fiber STM-1 / 4 155M / 622M transmission, and some have Gigabit 10 Gigabit Ethernet transmission. For such diverse links, different companies use different boards to collect corresponding link signaling. However, due to the increase in data traffic, associated data services are often shared among multiple links for tra...
