Technical field
The present invention relates to communication technical field, particularly relate to a kind of method of information updating, device
And system.
Background technology
At present at SIP (the Session Initiation of terminal with many network elements server composition
Protocol, Session initiation Protocol) in network, use DNS-SRV (Domain Name
System-SRV, server resource record) inquire about the load balancing realizing server.DNS-SRV
Record be DNS (Domain Name System, domain name system) server data base in support
The type of a kind of resource record.
In the prior art, the dynamics of load balancing depends on the DNS request of sip terminal own
Cycle.In existing DNS request model, the burden of comprehensive dns server considers, for DNS
Record all has ageing time T1 of a default, and the repetitive requests in T1 directly returns system
, meanwhile, in sip server, there is registration period T2 in the data in system buffering simultaneously,
Before registration period T2 arrives, sip terminal will refresh the registration on registrar, Er Qie
Before T1 ageing time arrives, sip terminal needs to carry out SRV request to dns server and updates
Local registrar IP (Internet Protocol, the agreement of interconnection between network)
Location priority list.
Sip terminal DNS-SRV ageing time is T1, and SIP registration refresh cycle time is T2,
And T2 " T1, under normal circumstances T2=1h, T1=24h.When there is registrar A and registration
During server N, obtaining priority after one takes turns priority list inquiry is P1, DNS service
Device priority is also P1, and the priority of the registrar A that wherein P1 comprises is more than registration service
The load of the priority of device N, the i.e. registrar A load less than registrar N, because of
This sip terminal sends registration request to registrar A.At sip terminal not to registration clothes
Before registration request initiated by business device, ask along with substantial amounts of terminal initiates registration to registrar A
Asking, the load on registrar A gets more and more, and makes registrar A and registrar N
On load change, trigger load balance calculate, result is that P2, P2 represent registration service
The priority of the device N priority more than registrar A, now dns server priority is
P2.When T1 time-out, sip terminal actively initiates DNS-SRV inquiry, and now sip terminal is preferential
The priority of level list is P2.When, after T2 time-out, sip terminal actively initiates SIP registration, this
Time purpose be registrar N, the duty factor registrar A of registrar N is light so that
More terminal, after getting P2, is initiated registration to registrar N and is refreshed, registration service
Device A load will reduce, and registrar N loads increase, causes again triggering equilibrium, and DNS is excellent
First level becomes P1 so that Priority Inversions.Above step, registrar A and registration clothes
The process of load dynamically change is presented so that registrar A and registration service between business device N
The average load of device N is equal.
During stating prior art in realization, when use T1 " T2 strategy time, can only be with T1
The load of cycle granularity refresh registration server, the Request Priority strategy meeting that such terminal is initiated
Lag behind the priority policy after load balance, affect the real-time of load balancing strategy；When adopting
During with T1 ＜=T2 strategy, it can be ensured that registration request can refresh with registration period granularity every time
Registrar initiates registration request, but so can strengthen the load of dns server.
