Problems solved by technology

[0004] In the process of the present invention, the inventor finds that adopting the ICMP Ping method, due to the relatively low processing priority of the router to the Ping message, queuing delay is generated, and the error of the measurement result is relatively large
Moreover, some routers will filter out ICMP packets to prevent DOS attacks. When the destination host receives ICMP Ping messages, it is easy to be attacked; the measurement method using the IP performance measurement protocol IPMP is a measurement protocol for routers. To achieve IPMP measurement goals, routers must support it

Embodiment 1

[0029] Embodiment 1. A method for measuring IP transmission network QoS, see figure 2 , the measurement initiator communicates with the measurement responder through the IP network. The measurement initiator may be a user end device, such as a user host, an AP, and the like. The measurement response end may be a router, or a host, an access gateway AG or a network server.

[0030] Method flow see image 3 , including the steps:

[0031] A1. The measurement initiator establishes a measurement connection with the measurement responder.

[0032] Establishing a measurement connection between the measurement initiator and the measurement responder includes that the measurement initiator sends a measurement start request message to the measurement responder, and the measurement responder responds to the measurement initiator with a measurement start response message to determine the measurement establishment information of both parties. The measurement establishment The informa...

Embodiment 2

[0044] The specific implementation steps of embodiment two are as follows:

[0045] B1. Similar to A1, the measurement initiator establishes a measurement connection with the measurement responder.

[0046] B2, similar to A2, through the established measurement connection, the measurement initiator and the measurement responder perform measurement.

[0047] B3. After performing the measurement, the measurement initiator and the measurement responder disconnect the measurement connection. The specific process of this step includes:

[0048] B31. The measurement initiator sends a measurement end request message to the measurement responder;

[0049] B32. After receiving the measurement end request message, the measurement responder closes the measurement connection established in the B1 step;

[0050] B33. The measurement responder sends a measurement end response message to the measurement initiator, and the message includes the measurement results collected by the measurement ...

Embodiment 5

[0097] Embodiment 5, a measurement initiating device for measuring the QoS capability of an IP transmission network. see Figure 7 , including the following units: a first measurement connection establishment unit 71 , a first measurement unit 72 and a first calculation unit 74 .

[0098] The first measurement connection establishment unit 71 is configured to establish a measurement connection with the measurement response device, specifically including sending a measurement start request message, where the measurement start request message includes measurement establishment information of the measurement initiation device, and the measurement establishment information includes The measurement connection information may also include the information of the measurement traffic model; receive the measurement start response message sent by the measurement response device, the measurement start response message includes the measurement establishment information of the measurement r...

Abstract

The embodiment of the invention discloses a method and a device that measures quality of service of Internet network protocol IP. The embodiment of the invention includes the steps of: establishing a measuring connection among the measuring responding terminals; carrying out measurement among the measuring responding terminals by an upper layer message of transmitted IP layer according to the measuring connection; calculating QoS index of the IP transmission network according to measured result. In the embodiment of the invention, measuring the request message and the responding message adopts the upper layer message of transmitted IP layer with high priority to the message of the router, which enables the measurement to be accurate without support of the router and is universal and convenient by the measuring method.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and a device for measuring the service quality QoS (Quality of Service) of an Internet Protocol (IP, Internet Protocol) transmission network. Background technique [0002] IP transmission network plays a very important role in today's data communication. For example, there are multiple devices at home or in an enterprise that want to connect to the network wirelessly. They need to access the IP transmission network through an access point AP (AccessPoint). For the network diagram of the AP, see figure 1 , the AP is connected to the IP transmission network through the home gateway HGW (Home Gateway), and then connected to the access gateway AG (Access Gateway) of the mobile core network through the IP transmission network. The service of the AP is carried on the IP layer, and the service quality of the AP largely depends on the QoS capability of the IP transmissio...
