Abstract
The invention discloses a method, a device and a system for web restriction. The method comprises that first restriction information reported by equal nodes is received; and a node list is generated according to the first restriction information and a demanding request sent by a user terminal and the node list is returned to the user terminal. The restriction information of the equal nodes is reported to an index server, the restriction information is reported through the user terminal as well when the user terminal demands the node list from the index server and the node list of the user terminal is generated through the index server according to the restriction information. The phenomena that a large amount of failure transmission occurs and other application cannot be used normally which are caused by the fact that practical peer-to-peer (P2P) uplink and downlink bandwidth and the connecting number exceed restriction of a visited access network and the user terminal are avoided, impact on the equal nodes from aspects of a port and bandwidth is reduced and user experience is improved.
Description
Technical field
The present invention relates to a kind of data service technology, relate in particular to a kind of network limits method, Apparatus and system.
Background technology
Fig. 1 is IP multimedia system in prior art (IP Multimedia Subsystem is called for short IMS) point-to-point (peer to peer is called for short P2P) Frame of Streaming Media System figure.UE, CCS, index server (Tracker AS) consist of the P2P flow media distribution system jointly as shown in Figure 1.The content caching server of network side (Content Cache Server, be called for short CCS) and have IMS user terminal (the user equipment of P2P flow medium function, abbreviation UE) all can be used as peer node (Peer comprises UE and CCS) provides content fragment for other IMS P2P Streaming Media UE.TrackerAS is for information such as IP address from other available Peer to UE that return to, ports.After UE fetches Peer list from Tracker AS, will with Peer list in other Peer carry out further alternately, obtain the burst information (bitmap) that the latter can provide, and then fetch content fragment from these Peer, assembly unit is also play.UE also wants regularly to report the own content information that can provide to TrackerAS.
By Proxy Call Session Control Function (Proxy Call Session Control Function, abbreviation P-CSCF), inquiry CSCF (Interrogating CSCF, I-CSCF), serving CSCF (Serving CSCF, S-CSCF) and ownership subscription server (Home Subscriber Server, be called for short HSS) the IMS system that forms be used for the functions such as user management and business triggering.Tracker AS provides the P2P streaming media service take the form of IMS application server as IMS user.P2P message between UE and index server (Tracker AS) is encapsulated in (as being placed in the body of sip message) in the SIP signaling, carries out Signalling exchange by the IMS network.Interacting message between Peer is without the IMS network.
Fig. 2 is the interaction diagrams between UE and Tracker.As shown in Figure 2, comprise that UE gets node listing (Peer list) and upgrades the flow process of Peer list from Tracker, and the flow process that reports to Tracker of UE.The user can select Peer to carry out the data download from Peer list after initial demand obtains Peer list, and the downlink bandwidth that in process, some Peer can lose efficacy (as roll off the production line or network is connected with problem etc.), some Peer provides can reduce.When the video slicing that in too low or Peer list, the video resource transmit leg is stored when the overall burst downloading rate of available Peer can't form complete film source, UE will send acquisition request Peer list to Tracker AS again.
As shown in Figure 3 and Figure 4, Peer will regularly to the TrackerAS keep-alive, can carry relevant information, as the Peer state in the keep-alive process.Do not comprise at present that terminal and visited place are to the restriction of port, bandwidth.
For the unrestricted scene of access network, the defective of existing IMS P2P stream media system comprises:
(1) take too much port resource
UE by the IMS core net after Tracker AS gets Peer list, there is no to consider reasonability that UE and visited place home subscriber server IPCAN of living in (IPConnectivity Access Network) port thereof are taken due to the formulation of Peer list, according to the difference of Peer list generating algorithm, might return to numerous Peer for a UE.If too much from this class UE of this IPCAN access, with consuming a large amount of port resources of this UE and IPCAN of living in thereof, affect the normal use of other application.
(2) Tracker overdriven and excessively uploading
UE by the IMS core net after Tracker AS gets Peer list, because the formulation of Peer list does not have to consider reasonability to UE and visited place of living in IPCAN bandwidth occupancy thereof.For descending, difference according to Peer list generating algorithm, Tracker might return to other Peer that the contribution ability surpasses the UE demand, UE is possible " under super ", namely adopt the bandwidth downloading data greater than demand, in order to promote the contribution ability (this is generally determined by algorithm) of oneself.Equally, for descending, also might for a UE configuration a plurality of " by contributors ", cause the upstream bandwidth pressure of local IPCAN excessive.It is particularly unfavorable that this point moves access (especially it is eated dishes without rice or wine) for this class of 2G/3G/LTE.
For access network ports having or limit bandwidth scene, the defective of existing IMS P2P stream media system is:
For preventing P2P to the impact of access network, operator takes some restriction mechanism/strategies at the Access Network edge sometimes, as utilizes the linking number between two of firewall restriction IP address.In addition, also can limit the bandwidth of connection.Up-downgoing data traffic and the port that can guarantee like this Access Network takies " not can too much ".But, the restriction of this visited place, Tracker is ignorant.The UE of " good " that Tracker thinks may be subject to this restriction in fact contribute limited in one's ability, but but be assigned to other a plurality of UE.When other UE asks for data to it, but run into the situation of connection failure.Another kind of situation is that Tracker is that the Peer number of a UE feedback is a lot, but the descending linking number that UE can set up is limited, causes downloading rate limited and have to repeat follow the Tracker again will new Peer list.Above-mentioned two situations all can cause the P2P Algorithm Performance to descend (be because Tracker is " blind " to access limitation in essence, decision information is not enough), and failed transmission too much also can consist of pressure to Access Network simultaneously.

The system of the present embodiment reports index server by the restricted information with peer node, and user terminal also reports restricted information when asking for node listing to index server, and index server generates the node listing of this user terminal according to these restricted informations.Avoid occurring that actual P2P upstream and downstream bandwidth and linking number exceed visited place access network and user terminal restriction and appearance or other application of a large amount of failed transmission of causing can't normally be used, reduce the impact of port that peer node is subject to and bandwidth aspect, improve user's susceptibility.
In addition, affect by having increased visited place P2P restriction strategy the mechanism that index server generates node listing, make the node capacity of node listing be subject to the restriction of visited place operator, can not cause to access zone network and peer node the impact of port and bandwidth aspect, but thereby reduce as far as possible yet and do not known the generation of a large amount of failed transmission that cause due to access zone network at data surface control port or bandwidth signaling plane.
As shown in figure 17, because the Signalling exchange between all UE and Tracker all will pass through P-CSCF, and P-CSCF is the visited place entrance network element of IMS, grasp the message transmission between all UE and Tracker, therefore increasing the P2P limitation function on P-CSCF, is the signaling plane scheme the most convenient, that expense is minimum.
It should be noted that: above embodiment is only unrestricted in order to the present invention to be described, the present invention also is not limited in above-mentioned giving an example, and all do not break away from technical scheme and the improvement thereof of the spirit and scope of the present invention, and it all should be encompassed in claim scope of the present invention.
