Measuring apparatus and measuring method for IPTV access network

Abstract

The invention discloses a measuring device for an IPTV access network, wherein, the IPTV access network comprises an operation support system, a fluid media service system, a video resource system and a user terminal; the fluid media service system comprises a center fluid media server and a marginal fluid media server; the measuring device comprises a NAT network measuring channel setting module, a network delay module and a measuring module for message-losing rate, wherein, the NAT network measuring channel setting module is used to build up a measuring channel between the marginal fluid media server in the public network and a client terminal in the private network and generate the measuring message and test the network quality; the network delay module is used to calculate the network delay while testing the network quality; the measuring module for message-losing rate is used to calculate the data of message-losing rate by periodically counting the number of measuring messages sent from the sending end to the receiving end within a set system cycle. The invention also discloses a measuring method for the IPTV access network. The invention can quickly locate and resolve network problems, thereby improving the service quality of the IPTV network.

Description

technical field [0001] The invention relates to the field of network quality diagnosis, in particular to a device and method for measuring network quality of an IPTV (Internet Protocol Television, Internet Protocol Television) access network. Background technique [0002] With the rapid development of the Internet (Internet), the network has gradually entered people's life, study and work, and has become an indispensable and important tool in modern society. Taking families as an example, users use the Internet to obtain information, watch IPTV, and use VoIP (Voice over IP, Internet telephony) communication, all of which are inseparable from the network. The network has become an important link between the family and the outside world. However, while the network has brought convenience to people, it has also brought new problems. With the development of network services, home users have stricter requirements on network bandwidth and network transmission quality, but IPTV acc...

Problems solved by technology

However, while the network has brought convenience to people, it has also brought new problems. With the development of network services, home users have stricter requirements on network bandwidth and network transmission quality, but IPTV access for families network, but there are complex network structures, various types of equipment, and unreliable network quality. Therefore, a convenient measurement tool is needed. Measurement positioning

[0003] Although such measurement tools currently exist in the industry, due to the special circumstances of the IPTV access network, for example, the IPTV access network is located at the terminal part of the Internet. This part is different from the backbone network, and its topology is complex. The following behaviors of the access network are dominant, so the downlink bandwidth is greater than the uplink bandwidth; and the terminal link of the access network is often inside the NAT (Network Address Transfer, Network Address Translation) network, and the equipment outside the NAT network cannot directly communicate with the intranet Features such as terminal communication

[0004] In summary, the existing IPTV access network network quality measurement technology obviously has inconvenience and defects in actual use, so it is necessary to design A Better Measurement Solution
