Description
Technical Field
The invention belongs to the technical field of Session Initiation Protocol (SIP), and particularly relates to a method and a device for evaluating the performance of an SIP server.
Background
The SIP protocol is a multimedia communication protocol established by the Internet Engineering Task Force (IETF). It is a text-based application-layer control protocol for creating, modifying and releasing sessions of one or more participants. The SIP is an IP voice session control protocol originated from the Internet, and has the characteristics of flexibility, easiness in implementation, convenience in expansion and the like. SIP is an application-layer signaling control protocol. For creating, modifying and releasing sessions of one or more participants. These sessions may be Internet multimedia conferences, IP telephony or multimedia distribution. The participants of the session may communicate by multicast (multicast), mesh unicast (unicast), or a mixture of both. SIP interoperates with the resource reservation protocol (RSVP) responsible for voice quality. It also cooperates with several other protocols, including multiple protocols such as Lightweight Directory Access Protocol (LDAP) which is responsible for location, remote authentication dial-in user service (RADIUS) which is responsible for authentication, and RTP which is responsible for real-time transport.
The SIP server is used to handle various SIP signaling. The performance of the SIP server is generally measured by the indexes such as the success rate of SIP transactions or the processing delay of SIP. Currently, the number of SIP critical signaling requests, the number of successes, the number of failures, and the processing delay of SIP critical signaling are generally used as performance points to evaluate the performance of the SIP server.
In the prior art, regarding SIP server performance dotting, generally, only several key SIP transactions are selected to dotte, such as a point call success rate and a group call success rate, which has the disadvantage of incomplete transactions. Moreover, the SIP server is divided into an upper service control module and a lower SIP protocol stack processing module from the architecture, the dotting position is generally located in the upper service control module, the lower SIP protocol stack module is often third-party software and is difficult to enter, and the processing capability of the lower SIP protocol stack processing module is also a part of the system performance of the SIP server. Therefore, for the time delay of the SIP signaling processing at present, the performance dotting is difficult to include the time delay of the SIP protocol stack processing, so that the time delay test is inaccurate.

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the accompanying drawings.
For simplicity and clarity of description, the invention will be described below by describing several representative embodiments. Numerous details of the embodiments are set forth to provide an understanding of the principles of the invention. It will be apparent, however, that the invention may be practiced without these specific details. Some embodiments are not described in detail, but rather are merely provided as frameworks, in order to avoid unnecessarily obscuring aspects of the invention. Hereinafter, "including" means "including but not limited to", "according to … …" means "at least according to … …, but not limited to … … only". In view of the language convention of chinese, the following description, when it does not specifically state the number of a component, means that the component may be one or more, or may be understood as at least one.
Aiming at the defect that the SIP signaling processing delay test range in the prior art difficultly covers the processing delay of an SIP protocol stack, the embodiment of the invention adds an SIP signaling receiving and sending process which is used as a unique SIP signaling inlet and a unique SIP signaling outlet of the SIP server in the SIP server, and forwards the received SIP signaling of an external network element to the SIP protocol stack in the SIP server; after receiving SIP signaling sent by SIP protocol stack of SIP server, it forwards it to external network element. In the process of receiving and sending the SIP signaling, the method points the SIP request from the external network element and the SIP response time delay of the SIP server, and comprehensively counts the signaling processing time delay of the SIP server.
Therefore, by setting the SIP signaling transceiving process as the unique SIP signaling inlet and the unique SIP signaling outlet, the embodiment of the invention can ensure that the performance dotting can cover the SIP protocol stack, thereby improving the accuracy of the time delay test.
Fig. 1 is a flowchart of a performance evaluation method of an SIP server according to an embodiment of the present invention.
As shown in fig. 1, the method includes:
step 101: enabling a SIP signaling transceiving process in a SIP server to receive a SIP request from outside the SIP server as a unique SIP signaling entry of the SIP server.
Preferably, the SIP request includes at least one of: registering a Register request; invite request; optional Options requests; subscribing to a Subscribe request; an Info request; refer to the Refer request; message request, etc.
The above exemplary description describes a typical example of a SIP request, and those skilled in the art will appreciate that this description is merely exemplary and is not intended to limit the scope of embodiments of the present invention.
Step 102: enabling the SIP signaling transceiving process to analyze a call identifier (call ID) from the SIP request, recording the first time when the SIP request reaches the SIP server, and sending the SIP request to a SIP protocol stack in the SIP server.
Wherein the call flags of the same session are the same. Accordingly, a SIP request and a SIP response corresponding to the SIP request can be correlated based on the session call. Wherein: the SIP response corresponding to the SIP request including a certain session call flag includes the same session call flag.
The SIP signaling transceiving process records the first time when the SIP request reaches the SIP server, and the first time is used as the starting time point for testing the processing delay of the SIP request.
Step 103: enabling the SIP signaling transceiving process to receive the SIP response containing the call mark from the SIP protocol stack, serving as the only SIP signaling outlet of the SIP server to send the SIP response to the outside of the SIP server, and recording the second time for sending the SIP response.
And the SIP signaling transceiving process records the second time for sending the SIP response as the termination time point for testing the processing delay of the SIP request.
The second time minus the first time is processing time delay from the SIP server receiving the SIP request to the SIP server sending the SIP response corresponding to the SIP request, and it is seen that the processing time delay covers the processing time of the SIP protocol stack, thereby improving accuracy of the time delay test.
Step 104: determining a processing delay of the SIP request based on a difference between the second time and the first time.
In the process of sending and receiving the SIP signaling, for all SIP requests from external network elements, such as Register, Invite, Options, Subscribe, Info, Refer, Message, etc., the respective number of attempts of the SIP request is respectively counted, the Call id of each SIP request is recorded, and the first time of each SIP request is recorded. And in the process of SIP signaling transceiving, separately counting all 2XX, 3XX, 4XX, 5XX and 6XX responses of each SIP request, recording the second time of the SIP response, and calculating the processing delay of the SIP request at the SIP server according to the corresponding Call id.
For example, the number of SIP signaling requests that do not respond back, the number of successful responses (2XX), the number of failed responses 3XX, the number of failed responses 4XX, the number of failed responses 5XX, the number of failed responses 6XX (which may also be more specifically counted, such as the number of failed responses 403, the number of failed responses 404, and the like), and the SIP signaling processing delay may be separately counted for all SIP requests (including Register, Invite, Options, Subscribe, Info, Refer, Message, and the like) in a fixed period (such as 5 minutes). And after counting is finished, clearing all SIP signaling request and response records in the period, and starting the next round of counting.
In one embodiment, the method further comprises:
enabling the SIP signaling transceiving process to analyze a type mark from the SIP request, and classifying the SIP request based on the type mark;
for each type of SIP request, the average processing delay is calculated based on the sum of the processing delays of the SIP requests in the type and the number of the SIP requests in the type.
In one embodiment, the method further comprises:
enabling the SIP signaling transceiving process to record the number of attempts of the SIP request;
enabling the SIP signaling transceiving process to analyze a type mark from the SIP request, and classifying the SIP request based on the type mark;
for each type of SIP request, the sum of the number of attempts for each SIP request in the type is determined.
In one embodiment, the method further comprises:
enabling the SIP signaling transceiving process to record a success failure code contained in the SIP response;
enabling the SIP signaling transceiving process to analyze a type mark from the SIP request, and classifying the SIP request based on the type mark;
for the SIP response of each type of SIP request, the success response percentage, the failure response percentage and the no response percentage of each SIP request in the type are determined based on the success failure code of each SIP response. The SIP signaling transceiving process may determine that the SIP response is a successful response, a failed response, or no response based on the successful-failed code.
Fig. 2 is an exemplary diagram illustrating a performance evaluation procedure of a SIP server according to an embodiment of the present invention.
As can be seen from fig. 2, the SIP signaling transceiving process in the SIP server serves as the only SIP signaling entry of the SIP server, and receives a SIP request from outside the SIP server. Wherein, the SIP request may include: register REQ (registration request); invite REQ (registration request); REQ Options (optional requests); subscribe REQ (subscription request); info REQ (information request); refer REQ (Refer request); message REQ (Message request), etc.
And the SIP signaling transceiving process records the call sign of each SIP request and the first time when the SIP request reaches the SIP server, and then sends the SIP request to the SIP protocol stack in the SIP server.

The SIP protocol stack may further interact with a service control process based on the functional interface, and so on.
The SIP protocol stack then returns a SIP response corresponding to the SIP request to the SIP signaling process, such as may be implemented as a 2XX response, a 3XX response, a 4XX response, a 5XX response, or a 6XX response, among others. Wherein the response of the Register REQ is Register RSP; the Invite REQ response is Invite; RSP; the response of REQ Options is REQ RSP; the response of the Subscribe REQ is a Subscribe RSP; the response of the Info REQ is Info RSP; the response of the Refer REQ is Refer RSP; the Message REQ response is a Message RSP.
The SIP signaling transceiving process is used as the only SIP signaling outlet of the SIP server to send the SIP response to the outside of the SIP server. The SIP signaling process records the call flag of each SIP response and the time of sending the response, i.e., the second time. And then finding out the SIP request corresponding to the SIP response based on the call sign, namely determining the processing delay of the SIP request based on the difference between the second time of the SIP response and the first time of the SIP request.
