Embodiment Construction

[0042] The basic thought of the present invention is: by setting DNS, cooperate VoIP client side to do DNS service (SRV, Service) record query request and response by DNS by DNS, carry the IP address of a plurality of VoIP servers in the DNS SRV query response message, each IP address With different priority and weight values, the VoIP client will preferentially select the VoIP server with the highest comprehensive calculation value of priority and weight value to register, if the registration fails, it will continue to register with the VoIP server with the next priority and weight value Request registration until the registration is successful.

[0043] The technical solution of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0044] Such as figure 1 As shown, the present invention guarantees the method for VoIP QoS from VoIP server load balancing aspect and comprises the following steps:

[0045] Step 101 , a...

Abstract

The invention discloses a method for guaranteeing quality of service (QoS) of a voice over internet protocol (VoIP), which comprises that: a client of the VoIP sends a DNS service record inquiry request message to a domain name system (DNS), and the request message carries a preset uniform resource locator address of servers of the VoIP; the DNS returns a DNS service record inquiry request response message to the client of the VoIP, and the response message carries an internet protocol IP address list of the servers of the VoIP and the priority and weighted value of each IP address; the client of the VoIP initiates a registration request to a server of the VoIP with the highest value for comprehensive calculation of the priority and the weighted value; and when the registration is failed, the registration request is initiated in turn to a server of the VoIP with the next level of the priority and weighted value until the registration is successful. The invention also discloses a system for guaranteeing QoS of VoIP. The method and the system can provide more stable service quality.

Description

technical field [0001] The present invention relates to the quality of service (QoS, Quality of Service) technology of VoIP (Voice over IP) voice communication, in particular to a method and system for guaranteeing VoIP QoS. Background technique [0002] At the end of the 20th century, the Internet (Internet) achieved great success and became a worldwide communication network following the Public Switched Telephone Network (PSTN, Public Switched Telephone Network). ) as the core packet switching data network has become one of the mainstream directions of the evolution of today's communication network. [0003] At present, multimedia communications such as audio and video on the Internet, which is dominated by data transmission, has become a hot spot in the development of communication technology. Among them, the successful development and application of IP telephony makes it possible to carry out voice services on IP networks, that is, VoIP services, and also heralds a brig...
