Active measuring system and method

Abstract

In use for testing quality of load-carrying network in next generation network, the active testing system includes testing gateway device and conversation control device. Testing gateway device is pointed as gateway device in next generation network for treating practical service. Under control of testing module, the testing gateway device builds testing service channel. Testing service streams are transmitted each other through the said channel to carry out testing quality of load-carrying network. Conversation control device pointed is pointed as conversation control device in next generation network. According to protocol, cooperated with the said testing module, the conversation control device takes part in operation for building testing service channel. Through testing gateway device and conversation control device to carry out service testing, the invention simulates practical quality of load-carrying network.

Description

technical field [0001] The invention relates to the next generation network technology, in particular to an active test system and method for testing the quality of the bearer network in the next generation network. Background technique [0002] With the rapid development of telecommunication technology, the Next Generation Network (NGN, Next Generation Network) with the packet network as the core bearer network is changing the concept and system of the traditional telecommunication network. [0003] In the network architecture of NGN, the core bearer network adopts the Internet Protocol (IP, Internet Protocol) packet network, and the IP packet network distributes packet data packets in the business mode of Best Effort (BE, Best Effort), which is impossible like traditional circuit Domain bearer network can also guarantee the real-time and integrity of the business; in the process of business transmission, abnormal situations such as packet loss, network delay and network ji...

Problems solved by technology

[0009] 1) The foundation of this test plan is to assume that the test service flow and the actual service flow take the same route in the bearer network. At present, many gateway devices provide service level classification functions at the service flow egress. Therefore, for bearer networks that support differential service processing Generally speaking, the unclassified test traffic flow and the classified test traffic flow actually take different routes, and in this prior art, the generation of the test traffic flow has nothing to do with the gateway device, that is, when the test starts, the two Two test endpoints directly send test service data packets to each other through the service switching point in the bearer network, and the routers in the bearer network complete the data packet forwarding, and the gateway device does not participate in the whole process, that is, the test service flow cannot reflect The working status of the actual service flow cannot reflect the real bearer network quality

[0010] 2) In the so-called NGN application, the sending process of the service flow data message is: the sender (such as the sending gateway) takes the IP address of the receiver (such as the receiving gateway) as the destination IP address, and puts it in the data packet to be sent. The header of the message is directly sent to the bearer network, and the entire transmission process is routed by the bearer network according to the destination IP address, so there are multiple feasible routes at the same time, and the overall QOS quality cannot be controlled

The business process of establishing a connection is completely different from the actual business process. The test service flow and the actual service flow will pass through different paths. Therefore, the analysis of the test service flow can only reflect the quality of the bearer network path that the test service flow passes through, and cannot reflect the quality of the test service flow. The quality status of the bearer network path that the actual service flow passes through

[0013] 3) This technology requires external test endpoints, test management centers and other equipment, which is expensive, and the test endpoint must be as close as possible to the gateway device to be tested, which is inconvenient to install, and it also brings inconvenience to construction and maintenance due to the addition of new equipment
