Embodiment 1

[0049] see figure 2 , figure 2 It is a schematic structural diagram of a first preferred embodiment of an apparatus for implementing multi-link load sharing according to the present invention. As shown in the figure, the device includes: 8 PPP links, wherein each PPP link has an LCP processing module 200, and a plurality of LCP processing modules share one NCP processing module and Multilink Control Protocol (MLCP) processing Module, NCP processing module and MLCP processing module constitute point-to-point multi-link (PPP MP) processing module 230 together, also comprise a failure detection module 210 and a load sharing calculation module 220 in addition, wherein PPP MP processing module 230 and load sharing calculation module 220 together constitute a load sharing scheduling module. In addition, in order to completely describe the transmission process of data and voice, the device also includes an IP protocol processing module 240 .

[0050] Among them, the LCP processi...

Embodiment 2

[0074] see Figure 4 , Figure 4It is a schematic structural diagram of a second preferred embodiment of an apparatus for realizing multi-link load sharing in the present invention. In the device of this embodiment, each PPP link of the multiple PPP links included includes: an LCP processing module and an NCP processing module, and forms a separate module 400, and in addition, only the MLCP processing module is included in the PPP MP processing module 410 , the functions and connections of other modules are related to figure 2 Same in the shown embodiment.

[0075] Wherein, the PPP MP processing module 410 is used to gather multiple links to form a single high-bandwidth bundle, that is, to generate an MP bundle comprising multiple PPP links; Send a query to query the available link channels allocated for the current IP data packet. This query method can be realized by calling the function provided by the load sharing calculation module 220, and then select and send the cur...

Embodiment 3

[0078] see Figure 5 , Figure 5 It is a schematic structural diagram of a third preferred embodiment of an apparatus for implementing multi-link load sharing in the present invention. This example is in figure 2 Based on the illustrated embodiment, in order to completely describe the signaling transmission process, a TCP / SCTP processing module 500 is added to implement data retransmission to ensure that the data is completely received. When sending data, the TCP / SCTP protocol processing module 500 packages the data that needs to be sent to the opposite end, and sends it to the corresponding IP processing module 240; when receiving data, the TCP / SCTP protocol processing module 500 sends the received IP processing module Analyze the data and check whether the receiving sequence number is normal. Once a data packet is found to be lost, it will send a data retransmission request to the other party until the complete data is received; or give up the retransmission request afte...

Abstract

A load sharing device of multilink transmission distributes load sharing dispatch module of usable link channel dynamically for IP data packet by adding fault detection module used for dynamically detecting quality of each link according to report result of fault detection module in order to let said device realize load sharing of multilink transmission for effectively relaxing load pressure on each single link.

Description

technical field [0001] The present invention relates to multi-link transmission technology, in particular to a device and method for realizing load sharing of multi-link transmission. Background technique [0002] In the communication system, IP technology is based on the address (IP Address) and best-effort forwarding (BE, Best Effort) mechanism, which has the advantages of flexibility and versatility, so it has been more and more widely used in the transmission of signaling, data and voice. application. In theory, IP technology can be used on any physical medium, but in fact, IP was first and most used on Ethernet, because there is a MAC address on the Ethernet card, which can correspond to the IP address one by one. In this way, the link layer on the Ethernet is very simple, which is to implement a media access control (MAC) function, do some channel processing, conflict detection and the like. [0003] If IP technology is to be applied to physical media not based on ad...
