Network traffic collaborative offloading method and cooperative offloading controller

Abstract

The invention provides a network traffic collaborative unloading method and a controller, and relates to the technical field of the computer network communication. The method comprises the following steps: sensing and recording user node state information in real time according to request data sent by a user node, and classifying and storing the user node state information; selecting one user nodeas an unloading source node according to the classified user node state information, and taking other user nodes except the unloading source node as a subscription node; sending the node informationof the unloading source node to all user nodes in a communication subset, wherein the unloading source node establishes connection with a server to receive network data traffic after confirming the own identity, and the unloading source node can sufficiently utilize the direction communication between the equipment to distribute the data. An unloading source is selected by adopting a collaborativeunloading source selection policy, the unloading source node can sufficiently utilize the direct communication between the equipment to distribute the data, the network resource is sufficiently utilized, the transmission efficiency is effectively improved, the traffic transmission pressure of a core network is lightened, and the user experience quality is guaranteed at the same time.

Description

technical field [0001] The invention relates to the technical fields of computer network and communication, in particular to a network traffic cooperative unloading method and a cooperative unloading controller. Background technique [0002] With the continuous development of science and technology, modern wireless communication technology has undergone earth-shaking changes, gradually showing the following prominent features. [0003] The first feature is that the heterogeneity of the network is prominent, and a single network communication technology can no longer meet the personalized service needs of users. Therefore, heterogeneous networks have become a research hotspot in future technologies. The second feature is the huge amount of mobile data. The third feature is that the mobile terminal presents a multi-homing form. The multi-homing feature of the terminal device can realize the transformation of the user from the original single network communication to the multi...

Problems solved by technology

Therefore, the improvement of transmission quality cannot be completed in a short period of time by only relying on the transformation of the network architecture

[0006] However, the multi-path transmission mechanism has the following defects: if the multi-path transmission mechanism is directly applied in a heterogeneous and asymmetric network environment, serious out-of-order and cache blocking phenomena will occur

However, caching of large amounts of data can lead to cache blocking, severely degrading application performance

[0007] For network traffic offloading techniques, which are currently still imperfect, in D2D offloading strategies, the probability of successfully retrieving desired content through opportunistic communication is rather small, resulting in very low offloading gain

At the same time, this solution cannot complete the selection of offloading links based on the real-time status of business traffic

In addition, the above solutions do not reasonably match the QoS (Quality of Service) requirements of network services and the service provision capabilities of optional offload links, so that the quality of service for offloading and the load balancing of the entire network cannot be guaranteed.
