Description
Technical field
The present invention relates to multi-core technology.More specifically, the present invention relates to a kind of session initiation protocol (Session Initiation Protocol, SIP) message treatment method and device based on multinuclear.
Background technology
(Next Generation Network NGN) is a kind of emerging network technology to next generation network.Its communication service that appears as provides greater functionality and advantage, also makes the live load of network significantly increase simultaneously.Yet because the performance of the sip application server of next generation network communication is also poor, so it still can not satisfy the requirement of NGN.
For the improvement of sip application server performance, crucial provide a kind of high performance Session Initiation Protocol stack." outwards expansion " technology based on multinuclear improves one of mode of Session Initiation Protocol stack performance just, and " outwards expansion " technology of being somebody's turn to do is through increasing the performance that processing unit promotes the Session Initiation Protocol stack.Wherein, multi-core technology is examined through integrated a plurality of complete computers in one piece of processor and is realized that " outwards expansion ", multiprocessor technology then are to realize " outwards expansion " through integrated a plurality of processors on server.And a plurality of processors in the multiprocessor technology can have single nuclear or a plurality of nuclear.
When technology improved the performance of server, the problem that must solve was how to make full use of the computational resource of each nuclear and internuclear interference and resource contention are minimized utilizing " outwards expansion " based on multinuclear.Mainly comprise the method for designing that is called streamline (pipeline), be called the method for designing that runs through (go through) etc. based on the conventional art of " outwards expansion " of multinuclear.
The sketch map that runs through method for designing has been shown among Fig. 1.As shown in Figure 1, sip stack 100 is divided into a plurality of layers, includes transport layer 101, analytic sheaf 102, transaction layer 103, dialogue/session layer 104 and application layer 105.According to running through method for designing, each nuclear is all carried out the function of all layers of sip stack.In the method, all are examined when the treatment S IP message, need utilize these shared resources such as transaction table, conversational list, conversational guidance, timer, I/O queue, IOQ etc.Fig. 6 shows the sketch map of transaction table, conversational list, conversational guidance, and wherein transaction table, conversational list, conversational guidance are respectively applied for the required information of stores processor sip message, such as the state of affairs, session, dialogue, relevant SIP information etc.The resource that need utilize when timer and I/O queue, IOQ also are the treatment S IP message.Yet, when a nuclear just visiting shared resource such as transaction table, conversational list, conversational guidance (for example, carry out search, create, modification, deletion action etc.) this resource of Shi Huiwei locks, other nuclears can't be visited this resource, must wait.And, when the throughput of sip message is big, utilize timer, I/O queue, IOQ etc. possibly also need to wait for.Therefore there is the resource contention problem between each nuclear.Like this, after the quantity of nuclear was more, it is even more serious that resource contention just becomes, and makes the overall performance of server can not be effectively improve with the increase of nuclear volume.
Similarly, also has another kind of method, i.e. the The pipeline design method.As shown in Figure 2, sip stack is divided into a plurality of layers equally: transport layer 101, analytic sheaf 102, transaction layer 103, dialogue/session layer 104 and application layer 105 are respectively every layer then and distribute some nuclears.This The pipeline design method has realized " outwards expansion " to a certain extent.But be difficult to the live load between each layer of dynamic equilibrium, therefore can't make full use of the computational resource of each nuclear.What is more important, when having distributed some nuclear for certain layer (like transaction layer 103), each nuclear in this layer also need be shared certain resource, such as transaction table, conversational list, conversational guidance, timer, I/O queue, IOQ etc.Yet, when a nuclear just visiting shared resource such as transaction table, conversational list, conversational guidance (for example, carry out search, create, modification, deletion action etc.) this resource of Shi Huiwei locks, other nuclears can't be visited this resource, must wait.And, when the throughput of sip message is big, utilize timer, I/O queue, IOQ etc. possibly also need to wait for.Therefore with to run through method for designing similar, also there is the resource contention problem between the nuclear when utilizing pipelining technique.
Therefore, method of the prior art still can not provide gratifying solution at present.

Embodiment
Hereinafter, will describe the sip message processing method and the sip message processing unit that the present invention is based on multinuclear through embodiment with reference to accompanying drawing.
Describe with reference to 3 pairs of sip message processing methods of the present invention of figure.Fig. 3 shows according to one embodiment of present invention the flow chart based on the sip message processing method of multinuclear.
In step 301, the sip message that receives is resolved in advance, therefrom to obtain the sign of said sip message.Sip message usually can through such as UDP (UserDatagram Protocol, UDP) or transmission control protocol (Transmission ControlProtocol TCP) transmits.The sip message that receives is placed on usually and carries out buffer memory in the formation.When taking turns to this sip message of processing, just this sip message is taken out from formation.Then this sip message is resolved in advance, therefrom to obtain the sign of sip message.The sign of said sip message can be used for identifying the correlation between the sip message, and will have the sip message that the sip message of like-identified thinks to have correlation.The sign of said sip message can be: the sign sip message belongs to dialogue (dialogue) sign of which dialogue; The sign sip message belongs to session (session) sign of which session; The sign sip message belongs to affairs (transaction) sign of which affairs; And any other sign that can identify the sip message correlation.(Internet Engineering Task Force, IETF) (Request For Comments RFC) in 3261, describes the definition of affairs, session and dialogue in detail to Request for Comment to the engineering group in the Internet.According to the description in the Session Initiation Protocol, the SIP affairs are carried out in client and service end, and comprise from client and be sent to all message that first request of service end is replied (non-1xx) up to the termination of sending to client from service end.If request is INVITE request and termination replys is replying of a non-2xx, affairs also comprise the affirmation of replying for said non-2xx so.And the ACK that replys to the 2xx for the INVITE request responds, and then is independently affairs.According to SDP regulation, " Multimedia session be multimedia transmit leg and recipient and from the transmit leg to recipient between the set of data flow.Multimedia conferencing is exactly an instance of Multimedia session." (RFC 2327 [1]) (the defined session of SDP can comprise one or more RTP sessions).As defined, a callee can repeatedly be invited to same session by different call.If used SDP, then session can be defined by the set string of SDP user name, session identification, network type, address style, address element.In the definition of RFC3261, dialogue is the relation of SIP end to end that continues a period of time between two UA.Dialogue is set up by sip message, replys such as " 2xx " for the INVITE request.Talk with call identification (call identifier), local label (local tag), the other side's label (remote tag) identifies.If one " INVITE " and " 200ok " have set up a dialogue, the re-invite of back then, sessions such as bye all belong to this dialogue.More information about dialogue, session, affairs please refer to the associated description among the RFC 3261.
The sign of sip message can be obtained from the structure of sip message.Below with reference to Fig. 4 the sign of sip message is described in detail.
Fig. 4 shows a representative instance of sip message structure.As can be seen from the figure, sip message 400 comprises a plurality of header fields, includes " Via " field 401, " From " field 402, " To " field 403, " Call-ID " field 404 etc.Wherein, the source address of the information representation sip message in " From " field 402, the destination address of the information representation sip message in " To " field 403, the sign that the information representation in " Call-ID " 404 fields is called out.In addition; The transmission of certain affairs of information representation in " Via " field 401 and sign are replied the address of replying; Include " branch " parameter 405 in " Via " field 401 in sip message; " branch " parameter 405 is used for the affairs that identification request is created, so this parameter can be used for distinguishing affairs.
In one embodiment, the tlv triple that the sign of sip message is made up of the information in " From " field 402, " To " field 403 and " Call-ID " field 404 in the sip message structure, this tlv triple has identified dialogue.In this embodiment, the sip message that belongs to same dialog is considered to have correlation.Therefore, the sign of this tlv triple formation can be used as dialogue identifier.
In another embodiment; The sign of sip message is by the four-tuple of the information formation of " branch " parameter 405 in " From " field 402, " To " field 403 and " Call-ID " field 404 and " Via " field 401 in the sip message structure, and this four-tuple has identified affairs.In this embodiment, the sip message that belongs to same transaction is considered to have correlation.Therefore, the sign of this four-tuple formation can be used as Transaction Identifier.
Those of ordinary skill in the art understands, and in other embodiment, also can session and any other possible sip message be identified according to other field.
According to applicable cases, can select in dialogue identifier, session identification and the Transaction Identifier any as the correlation between the mark for marking sip message of sip message.For example, when being intended to avoid resource contention to a greater degree, can adopt dialogue identifier or session identification; And be intended to reduce the preliminary treatment expense is target, then can adopt Transaction Identifier.In addition, under the situation that does not break away from the spirit and scope of the present invention, also can adopt other modes to constitute the sign of sip message.
Then, in step 302, the sip message that will have like-identified is assigned in the identical nuclear.
In one embodiment, utilize the sip message sign that obtains in the step 301, in mapping table, search the nuclear corresponding with the sign of the sip message that is obtained, said mapping table has write down the sign of sip message and the corresponding relation between the nuclear.Following table 1 shows the illustrative instance that mapping table utilizes the dialogue of said tlv triple sign.In this table, the sign of sip message is a dialogue identifier, and this dialogue identifier is the tlv triple that is made up of the information in " From " field, " To " field and " Call-ID " field, and three nuclears that are used for the treatment S IP message are arranged: nuclear 1, examine 2 and examine 3.All sip messages that use identical tlv triple to identify all will be assigned in the identical nuclear.
Table 1
Then, if in mapping table, do not find the sign of this sip message, show that then this sip message is a new message, does not promptly also exist the sip message relevant with this sip message.In this case, in mapping table, set up the sign of this sip message and the mapping between nuclear, use for relevant with this sip message subsequently sip message.Then, sip message is distributed to this nuclear.On the other hand, when finding the nuclear corresponding with the sign of this SIP, just with this distribution of messages in the nuclear that finds.
In another embodiment, do not utilize above-mentioned mapping table, but adopt the mode of directly distributing.In this embodiment, utilized a kind of simple ashing technique.At first basis is resolved the sign that obtains sip message in advance and is calculated corresponding integer numerical value, and it is surplus to utilize the number of examining that this numerical value is got then, distributes sip message according to remainder.This calculating operation can carry out according to following formula:
R＝Mod(F(ID)，N)
The remainder that obtains of " R " ecbatic wherein; " ID " is the sign of sip message; F is the function of the corresponding integer numerical value of the sign " ID " that is used to calculate sip message; N is the quantity that is used for the nuclear of sip message processing, and (para1 is to get cofunction para2) to function MOD, is used for the remainder that return parameters para1 obtains divided by parameter p ara2.
For example; Promptly examine 1 at four nuclears that have, nuclear 2, nuclear 3 and examine under 4 the situation; 4 pairs of quantity can utilizing nuclear obtain to such an extent that get surplusly with the sign value corresponding F (ID) of sip message according to function F, and remainder is that all sip messages of 1 are distributed to nuclear 1, and remainder is that all sip messages of 2 are distributed to nuclear 2; Remainder is that all sip messages of 3 are distributed to nuclear 3, and remainder is that all sip messages of 0 are distributed to nuclear 4.In this way, just need not to utilize the corresponding relation that writes down in the mapping table between this sign and the nuclear.
In addition, can also utilize the ashing technique of other modes, perhaps utilize the additive method that can directly distribute sip message.And, when distributing sip message,, when perhaps directly distributing sip message, also can utilize load balancing method well known in the art to come the live load between each nuclear of balance when setting up above-mentioned mapping, such as wheel change, at random, method such as weighted round robin.Then, in step 303, on each nuclear, utilize relevant private resource that the sip message of distributing to said nuclear is handled.The mode that this processing can utilize sip message of the prior art to handle is handled.
In one embodiment, the relevant private resource that distributes for each nuclear comprises transaction table.In a further embodiment, said relevant private resource may further include one or more in conversational list, conversational guidance, timer, the I/O queue, IOQ etc.Special-purpose transaction table, conversational list and conversational guidance have been stored the required information of treatment S IP message, such as the state of affairs, session, dialogue, relevant sip message etc.Because the required information of treatment S IP message all is stored in the relevant private resource of nuclear oneself; Therefore if nuclear need the information relevant with the sip message that it is being handled when handling; This nuclear just only needs these private resources of visit, needn't visit the resource of other nuclears.And nuclear also can utilize special-purpose timer and I/O queue, IOQ, and needn't share with other nuclear.Like this, just reduced the needs of access shared resources, reduced the resource contention between the nuclear and therefore improved the utilance of the computational resource of nuclear.
When using Transaction Identifier, the sip message that belongs to same transaction is handled in identical nuclear, so said relevant private resource comprises transaction table.Transaction table through each nuclear is special-purpose can be searched the relevant information that other belong to the sip message of same transaction.
When using session identification or dialogue identifier, the sip message that belongs to same dialog or same session is handled in identical nuclear, and can use transaction table to search the relevant information of the sip message that belongs to same session or dialogue this moment.In addition, said relevant private resource can also comprise conversational list or conversational guidance, can use transaction table and conversational list or conversational guidance to search the relevant information of the sip message that belongs to same session or dialogue like this.
According to application demand, said relevant private resource can also comprise one or more in timer and the I/O queue, IOQ etc., with the processing speed of further raising sip message.
Main thought of the present invention is: the sip message that will have correlation is dispensed in the identical nuclear to be handled, and visits same shared resource (such as transaction table) simultaneously to avoid a plurality of nuclears.For this reason, before sip message is handled, carried out preparatory parsing, all be placed in the identical nuclear with the sip message that will have correlation and handle.Therefore, significantly reduce the possibility that the sip message that has correlation because of a plurality of nuclear concurrent processing needs the same section of access shared resources, therefore reduced resource contention, and improved the utilance of the computational resource of nuclear.And the result of micro benchmark test illustrates: on the 1.6G of Thinkpad Pentium M processor, can reach per minute and resolve 400,000 sip messages in advance.This shows that parsing only is a lightweight task in advance, does not almost increase the load of processor, so overall performance is also to significantly improving.
Therefore, the present invention can be used to improve the The pipeline design method, run through method for designing or any existing multinuclear method for designing.Particularly, when the present invention is used to improve the The pipeline design method, can reduce the possibility that needs the same shared resource of visit because of the sip message that has correlation with a plurality of nuclear concurrent processing in one deck; When the present invention is used to run through method for designing, can reduces a plurality of nuclear concurrent processing on the whole and have the sip message of correlation and need visit same shared resource
Described sip message is resolved in advance and sip message distributes and can carry out through the nuclear of a special use, also can carry out through a nuclear that is used for the treatment S IP message.For example in the bigger applied environment of data throughout, preferably carry out, can improve the pre-treating speed of sip message like this through the nuclear of special use.And under the little situation of data throughout, preferably carry out through a nuclear that is used for the treatment S IP message.In this case, because throughput is little and preliminary treatment sip message is the task of lightweight, therefore can influence the processing of sip message, and can make full use of the computational resource of nuclear yet.In addition, sip message is resolved in advance and sip message distributes and can also realize through special designs hardware, such as network processing unit (NP, Network Processor), transmission control protocol load balancing engine (TOE, TCPOffload Engine) etc.
In another preferred embodiment, said nuclear is supported multithreading, has the hardware thread (hardware thread) of a plurality of physics in the promptly said nuclear.In this embodiment; Sip message with correlation is assigned in the same hardware thread of identical nuclear; On the hardware thread of said nuclear, to handle said sip message; And make each hardware thread in each nuclear have oneself relevant private resource, such as in transaction table, conversational list, conversational guidance, timer, the I/O queue, IOQ etc. one or more.In this way, make and on each hardware thread, to utilize the private resource of hardware thread to come the treatment S IP message, thereby further reduced resource contention and therefore improved the utilance of the computational resource of nuclear.
