Problems solved by technology

In the past, it was only possible to lay or rent dedicated lines (Ethernet, E1, etc.). In recent years, with the improvement of technology, MPLS transmission mode has become a possibility, but the high cost of network construction (such as the load of equipment of various equipment manufacturers Allocation algorithms are different and not compatible) has been an unsolvable problem

Embodiment Construction

[0023] The present invention will be described in further detail below in conjunction with accompanying drawing:

[0024] Figure 1 and Figure 2 are the connection diagram and implementation process of adaptive load distribution.

[0025] As shown in Figure 1, the private network device is connected to each device of ② through ①; ② is connected to ⑤ through ③, and ③ is aggregated into ④ through the link aggregation function on ⑤;

[0026] Since ① of connection ② corresponds uniquely to each physical line, a state of multi-tunnel link aggregation can be realized, and through the reverse principle of multi-tunnel link aggregation transmission, each node device on the network will eventually default to the private network end device There is a logical physical connection with ⑤, and finally the link aggregation on ⑤ can be realized;

[0027] Due to the link aggregation between the private network device and ⑤, when the tunnel of a certain connection is disconnected, the data traf...

Abstract

The invention relates to a Multi-tunnel Adaptive load distribution Transmission technology (MALT) which is suitable for connecting a private network to a backbone network by a plurality of tunnels, finally finishing the tunnels flow aggregation of lines of a core transmission equipment group in the backbone network, adaptively distributing the line loads by main core exchange equipment and finishing data transmission among equipment. The multi-point multi-tunnels adaptive load distribution transmission technology is characterized in that private network end transmission equipment is connected with the core transmission equipment group in the backbone network by different tunnels and totally joins in the main core exchange equipment with the load-distributing function so that on one hand, transmission bandwidths are aggregated by link aggregation, and meanwhile, under the peak value stacking state of the transmission bandwidths, different physical lines between the core transmission equipment group and the private network end transmission equipment can automatically distribute flows according to the jamming condition of the network or actively distribute flows as required. Operators and service providers during providing service for clients can effectively improve the line quality with the client ends and provide more personalized services.

Description

Technical field [0001] The invention relates to the field of communication transmission, in particular to a data center terminal adaptive load distribution and transmission technology through multi-point and multi-tunnel when a service provider provides services to customers. technical background [0002] Load Balance Based on the existing network structure, it provides a cheap, effective and transparent method to expand the bandwidth of network devices and servers, increase throughput, strengthen network data processing capabilities, and improve network flexibility and availability. Load balancing has two meanings: first, a large amount of concurrent access or data traffic is distributed to multiple node devices for separate processing, reducing the time for users to wait for a response; secondly, a single heavy-load operation is distributed to multiple node devices for parallel processing Processing, after the processing of each node device, the results are summarized and...
