Description
Technical field
The present invention relates to communication technical field, particularly a kind of subscription of the SOT state of termination and Notification Method, device.
Background technology
In some catenet information interaction systems, the user needs to pay close attention in real time the current state of some other users or equipment usually.Common way is, the user needs the terminal paid close attention to the subscription of status tracking server, and the status change notification that the status tracking server in real time will subscribed terminal is to the user.The user can be called the subscriber, and the status tracking server can be called the annunciator.
In the prior art, the subscriber with subscription information through sending to the annunciator, if the subscription information amount is bigger based on certain application layer protocol; The mode that also can adopt increment to send sends to the annunciator one by one; After the annunciator receives subscription information, can collect the current state at these subscribed terminals immediately, then these state informations are handed down to the subscriber one by one; Because the amount of information that issues maybe be bigger, also can adopt the mode of incremental distribution.In subsequent process, when monitoring certain SOT state of termination, the annunciator changes, can immediately this change information be handed down to the subscriber.If because factors such as unstable networks cause certain to subscribe to or notification message is lost, the sender can adopt retransmission mechanism to send once more usually.
Under above-mentioned scene, interacting message is very frequent, and normally takes place synchronously, and this has just proposed that to annunciator's concurrent ability very high requirement is arranged.Total institute is known, adopts transmission control protocol (TCP, Transmission Control Protocol) can set up a kind of reliable two-way connection; Can guarantee information intactly send to the other side; But because normally a kind of synchronous blocking model of Transmission Control Protocol, it is higher that each connection takies resource, and under the relatively poor situation of network environment; Blocking time can be long; If the use Transmission Control Protocol, the annunciator must start a large amount of thread concurrent processing, and annunciator's resource will soon approach exhaustion like this.Therefore, in this type of certain scale used, all be to adopt UDP (UDP, User Datagram Protocol) to carry out transmission of messages at present.As datagram transmission, both sides' udp protocol need not connect with message, and message is sent the back and do not known whether the other side receives, and mutual both sides adopt the asynchronous working mode usually, and efficient is high more than the TCP mode.
At present message is mainly comprised following aspect as the techniqueflow of datagram transmission to udp protocol:
(1) component is subscribed to: when subscribing to the announcement information amount bigger the time employing component send mode batchwise transfer.The length of each datagram of udp protocol is very limited, when the terminal quantity that need subscribe to as the user is a lot, just must subscribe to by component.
(2) after the annunciator receives subscriber's subscription terminal list, can the current state at all these terminals all be notified usually and give the subscriber.
(3) when subscribe to or notification message lose after the employing retransmission mechanism.Since the unreliability of udp protocol, when unstable networks, the situation that the datagram that can fall in is lost.Therefore a lot of annunciators and subscriber have retransmission mechanism, when certain affirmation of once not receiving the other side alternately, will resend.
(4) in during subscribing to, change, will this change notification be subscribed to the subscriber at this terminal to all when the annunciator monitors certain SOT state of termination.
Adopt retransmission mechanism can't guarantee that the subscriber understands the state of subscribing to the terminal really; And when the terminal quantity of subscribing to is huger; The annunciator need consume ample resources and send a notification message, and causes notification message quantity huge, and increase is lost the probability that brings status error because of notification message.
