Description
Technical field
The present invention relates to that (Peer to Peer realizes on basis P2P) that (Session Initiated Protocol, SIP) technology are called for short the P2P sip technique to conversation initialized protocol at peer-to-peer network.Relate in particular to a kind of distributed business network (Distribute Service Net, network configuration DST) and network establishing method thereof, and the core service device in this kind DST network and to the processing method of protocol massages.
Background technology
Next generation network (NGN) is supposed to be based upon on the basis of fixed telephone network, mobile network and internet converged, provides and the irrelevant multiple business of customer location.(IP Multimedia Subsystem IMS) is core network platform in the NGN system to be based upon IP Multimedia System on the manageable IP network.IMS is proposed by 3GPP, is accepted by 3GPP2/LTE ETSI at present.
The IMS system of standard is based upon on the SIP, is a kind of framework of main frame/client computer of standard.Typical IMS system session flow process is:
IMS user agent on its PC of first user activation, IP phone or the handheld terminal, the user agent can be with on the IP address registration of the equipment IMS core network server in the IMS system;
This first user's of IMS core network server storage common identity (for example first user's common identity by: sip:alicecmcc.com) and first user the mapping between the corresponding IP address/Hostname of use equipment;
When second user asked with first user's communication, this request meeting was redirected to this request on first user's the corresponding device by this IMS core network server via the IMS core network server in first user's affiliated territory.
This centralized framework of the IMS system of standard, main problem are the single point failure problems, and single point failure can take place when the IMS core network server loses efficacy, can cause functional forfeiture of whole system.In the prior art, the single point failure problem is to solve through the method for using traditional redundancy and fault recovery, for example adopts the IP address to take over, MAC Address adapter or application layer switching etc., but like this can the significant expenditure that increases system maintenance and configuration.This centralized framework has also limited the widespread deployment under some scene, especially when the user inserts the IMS core net and is limited, means that (for example urgency communication or meeting) is not easy to set up apace system under minienvironment.
Pure P2P network is the notion that does not have server.All participants are nodes, internodal communication also be in potential non-structured environment based on distributed, therefore, do not have the single point failure problem in the P2P network.
Above-mentioned advantage based on the P2P network; There have been many researchers to propose to use P2P network (like distributed hashtable DHT) that SIP registration and user location among the IMS are provided at present; Substitute technology that Here it is so-called " P2P SIP " with this as sip server in the IMS communication process.The system that uses the P2P sip technique to make up compares with the traditional server pattern, has characteristics such as load balancing, easy deployment and high robust are good.
In addition; For standardization P2P sip technique; IETF has set up P2P SIP working group specially and has been used for studying relevant important topic; Some relevant draft agreements occurred at present, and wherein the resource location has progressively become the popular protocol of P2P sip technique with finding agreement (RELOAD agreement) and peer to peer protocol (P2PP agreement).
The RELOAD agreement is the signaling protocol that is used for a P2P of the Internet.It provides distributed hashtable (DHT) service, allow to participate in node and can from Hash table, read and write items for information, and Hash table all is stored in the participation node.The RELOAD agreement is the agreement of a lightweight; Support the requirement of SIP in order to satisfy the P2P agreement; In the RELOAD agreement primary study security framework, application model, network address translation (Network Address Translation, NAT) pass through mechanism, high usage route mechanism, flexible transmission is machine-processed with can expand relevant content such as DHT algorithm.
The P2PP agreement is used to create and safeguard covering (overlay) network that some nodes are participated in.The design reference of P2PP has adopted relevant p2p agreement, bamboo for example, and chord, CAN, pastry, kademlia, Gia etc., so this P2PP agreement do not define the details of p2p agreement, cooperates mutually with the p2p agreement through designing relevant extension mechanism.The P2PP protocol definition NAT and Firewall Traversing mechanism, adopt transmission reliably, and defined the mechanism of switching node ability and diagnostic message.The P2PP agreement allows not participate in the node of overlay network obtains the overlay network through the node in the overlay network service.
In the RELOAD/P2PP agreement, be packaged with the Session Initiation Protocol subclass, can compatible Session Initiation Protocol.
The concrete realization of P2P sip technique has two kinds of schemes at present.A kind of scheme is " P2P over SIP ", promptly realizes the function of P2P through sip message; Another kind of scheme is called " SIP using P2P ", is about to SIP and is positioned on the P2P network, substitutes the positioning service of SIP through the locating function that calls P2P." SIPusing P2P " scheme has become the main flow implementation of P2P SIP because its realization is simple.
Adopt in " SIP using P2P " system of " SIP using P2P " scheme constructs, P2P agreement and Session Initiation Protocol are fully independently, and Session Initiation Protocol need not be modified.The resource positioning service that Session Initiation Protocol uses the P2P network to provide through the corresponding protocol translation interface.In addition, be structurized P2P DHT algorithm because the P2P network uses, Bamboo for example, Chord, and Pastry etc. can carry out the expansion of system under the situation of not changing any other deployment.The system configuration sketch map of " the SIP using P2P " scheme of use is as shown in Figure 1.
In " SIP using P2P " system; Distinguish super node and ordinary node; Super node forms the P2P core network through the P2P algorithm, and ordinary node (like node Alice among Fig. 1 and Node B ob) inserts the P2P core network through the standard Session Initiation Protocol through super node.For example: node Alice initiates insertion (INSERT) request of Session Initiation Protocol to the super node of P2P core network, and super node carries out protocol conversion, is P2P procotol message with the INSERT message conversion, realizes node Alice is inserted the P2P core network.In like manner, Node B ob is linked into the P2P core network after also can adopting Session Initiation Protocol to convert the P2P agreement into through super node.When Node B ob need send discovery (FIND) request of adopting Session Initiation Protocol, the mailing address of acquisition request node Alice through super node to the P2P core network earlier when node Alice communicates by letter; The super node of P2P core network will adopt the FIND request of Session Initiation Protocol to convert the request of adopting the P2P procotol into; And return to Node B ob obtain the mailing address of node Alice through the P2P core network after; Node B ob directly initiates to invite mailing address from (INVITE) message to node Alice such as sip:alice128.59.19.194, realizes communication between the two.
In above-mentioned " SIP using P2P " system; Because access protocol is a Session Initiation Protocol; And core network protocols is P2P procotol (multiple different privately owned P2P procotol can be arranged), between the existing standard IMS system and P2P core network that adopt Session Initiation Protocol, because access protocol and core network protocols is different; Need super node to accomplish the conversion of standard Session Initiation Protocol and privately owned P2P procotol, it realizes that complexity is higher.This kind of the prior art " SIP using P2P " system can't realize with standard I MS system and reach the intercommunication between other " SIP using P2P " system that adopts different P2P algorithms.
