Method for realizing IP telecommunication network based on tunnel

Abstract

The invention relates to technology of network communication, in particular to a method for realizing an IP telecommunication network based on a tunnel. Aiming at the defects in the prior art, the invention discloses the method for realizing the IP telecommunication network based on the tunnel, which smoothly transits under the condition of lower cost and not changing the prior network structure so as to realize end-to-end service quality guarantee for users and provide service of multiple IP QoS levels according to requirement for users. The invention adopts a technical proposal that: a plurality of independent resource domains are formed through planning a physical network. A resource tunnel of a domain is established in the resource domain, and data traffics with different service quality requirements are classified into different resource tunnels, thereby realizing that user data traffic can be transmitted in a resource tunnel in accordance with the user requirement on IP QoS level, and ensuring the QoS requirement of user service. For communication service for a specific user, a full range user tunnel is established inside the resource tunnel, and the user tunnel passes through the resource tunnel to form a multilayer tunnel.

Description

technical field [0001] The invention relates to network communication technology, in particular to a tunnel-based IP telecommunication network realization method. Background technique [0002] With the rapid development of the Internet today, businesses on it emerge in an endless stream, but the existing Internet architecture uses a best-effort mechanism for data transmission, which lacks management and control capabilities. For the current voice, video, private line and other business requirements that require high bandwidth guarantee and real-time performance, the quality cannot be guaranteed. Moreover, the following network uncertain phenomena have also occurred: [0003] One is the uncertainty of the communication path: multiple data packets from the source to the destination may pass through different network paths, and different time periods may also have different network paths; [0004] The second is the uncertainty of communication traffic: Since the existing IP n...

Problems solved by technology

[0003] One is the uncertainty of the communication path: multiple data packets from the source to the destination may pass through different network paths, and different time periods may also have different network paths;

[0004] The second is the uncertainty of communication traffic: Since the existing IP network does not have the ability to control the number of network accesses, nor does it have the ability to control the network access traffic, there may be a large amount of traffic at a certain node in the network at a certain point in time. Exceeds the capacity of the node, but there may still be new user access or new traffic injection at this time. This uncertain traffic will cause local congestion in the network, causing the communication of the connected users to be affected;

[0005] The third is the uncertainty of communication delay: due to the above two uncertainties, the delay of data packets passing through the network is affected by the network path and network congestion, and has uncertainty.

The standard recommends only deploying border gateway devices in the network, but to achieve real resource control, in addition to deploying related functional entities, it also expands many new requirements for the data device itself. These new requirements may lead to deployment of resource control. New data equipment or transformation and upgrading to replace existing network data equipment may require a large amount of investment to enable the bearer network to have a relatively complete resource control capability

In fact, the upgrade of the entire network equipment, especially the upgrade of some core systems, will become an obstacle to implementation
