Domain name resource records management method and device

Abstract

The embodiment of the invention provides a domain name resource records management method and device. The domain name resource records management method comprises the steps of receiving a subscription request message sent from a Domain Name System (DNS) server by a Network Function Virtualization Organizer (NFVO); and when a change event of an NS example changes, sending a notification message to the DNS server by the NFVO, wherein the notification message is used for notifying the DNS server of modifying domain name resource records based on the notification message. Consequently, the NFVO can notify the DNS server in time when a network changes (the NS example changes), so that the DNS server can update the domain name resource records automatically, thereby realizing dynamic adjustment of a service flow based on network change and responding demands of network services rapidly.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a domain name resource record management method and device. Background technique [0002] The network function virtualization (Network Function Virtualization, NFV for short) technology can be simply understood as migrating the functions of each network element used in the telecommunication network from the current dedicated hardware platform to a general-purpose server. Through NFV technology, each network element used in the telecommunications network is transformed into an independent application, which can be flexibly deployed on a unified infrastructure platform based on standard servers, storage devices, switches and other equipment, and through virtualization technology, the basic Facility hardware device resource pooling and virtualization, providing virtual resources for upper-layer applications, realizing the decoupling of applications and hardware...

AI Technical Summary

Problems solved by technology

[0004] After the telecom network becomes NFV, the network service (NetworkService, referred to as NS) can automatically expand or shrink to quickly meet business needs. After the expansion or shrinkage, the topology of NS will change accordingly, and the domain name system (Domain Name System, referred to as DNS) can be used. The server is used for network topology selection. The DNS server can realize the conversion between all computer names and IP addresses on the Internet, and realize business distribution. Network elements quickly and automatically complete route selection, but manual configuration is required according to NS network topology changes, resulting in the DNS server being unable to quickly respond to network service needs
