Method for ensuring quality of end-to-end service

Abstract

The invention discloses a method for guarantying the quality of terminal-terminal service, comprising: presetting a relative logical carrying network for each network and storing the information of logical carrying network into carrying control entity of each network; negotiating and building the logical channel between two networks; the first user terminal sends service request to the first network to request processing service conversion with the second user terminal of second network; the carrying control entities of first and second networks individually distribute the resource of route and bandwidth between self-network and the boundary port; and retransmitting said service flow between the logical carrying networks of said two networks according to the paths distributed by the carrying control entities of first and second networks. Said method can make the operators hide the self-network topology to solve the problem of communication failing caused by the un-trust between operators and meet the interconnection request between different operators.

Description

technical field [0001] The invention relates to end-to-end service quality (Qos) control technology, in particular to a method for ensuring end-to-end service quality. Background technique [0002] With the continuous expansion of the scale of the Internet (Internet), a variety of network services are emerging, and advanced multimedia systems are emerging in an endless stream. Since real-time services are sensitive to characteristics such as network transmission delay and delay jitter, when there are services such as file transfer (FTP) or hypertext transfer (HTTP) containing image files on the network, the real-time service will fail. In addition, because the multimedia service will occupy a large amount of bandwidth, it will also make it difficult to obtain reliable transmission of key services that need to be guaranteed in the existing network. Therefore, in order to ensure reliable transmission of key services, various QoS technologies emerge as the times require. The ...

Problems solved by technology

Although there is business execution control, but there is no reliability design and key node multi-homing features, the scalability is very poor, the network scale is limited, and it cannot meet the end-to-end service requirements of a national public network

[0010] A network with an independent bearer control layer or a centralized resource control layer uses a logical path, such as a label switching path (LSP), as the path of service data flow, when delivering flow mapping and policy configuration information, it is necessary to deliver the entire end-to-end path information To the edge device at the source end, when interoperating between operators, it is unacceptable for the operator to tell the path information of the operator’s network to another operator. At the same time, due to the trust problem between operators, the existing technical solution The intermediate resource manager (RM) in the network does not interact with the business layer or the management layer, and there will be loopholes such as cheating and attacking the other party when operators communicate with each other. For example, if operator A applies for a certain bandwidth from B, the actual operator B The network of operator A uses a relatively small bandwidth when transmitting data in operator A's network, which affects the communication quality of users in operator A's network, so steps need to be taken to make up for it
