The use of the SIP protocol is not uncommon. With the popularity of the VoIP service, we also have a better understanding of the SIP protocol. Here we will focus on the advantages of SIP. In this case, we need to compare this advantage with other protocols. Advantages of SIP: Service providers can select standard compo

This article will briefly introduce the Java Socket Direct protocol (Sockets Direct PROTOCOL,SDP) introduced in the Java 7 SDK, and this new technology is a very exciting breakthrough. If you want to native access to InfiniBand's remote Direct memory access (Sqlremote direct Memory ACCESS,RDMA), SDP enables ultra-high performance computing (Ultra high Performance Computing, UHPC) Community uses Java-generic

SDP, service Discovery Protocol, Services Discovery Protocol 1. Concept The SDP provides a way to discover services and the properties of those available services, but it does not provide a mechanism to take advantage of these services. The schema is Client-server mode, as shown in the following figure SDP Server maintains a list of service records, with each en

Many equipment manufacturers and operators have participated in the formulation of CS3 standards. (2) SIP-T Before introducing the SIP

, ice is a good fit for such requirements..2 ice technology 2.1 ice Introduction Interactive connectivity establishment method (ICE) is not a new protocol,It does not need to expand stun, turn, or rsip to apply to various Nat services. Ice is a comprehensive application of the aboveAgreement to make it work in the most appropriate circumstances, to make up for the inherent defects arising from the independent use of any of them. ForFor sip, ice only

behalf of other clients, acting as both a server and a client. Before forwarding a request, it can rewrite the content in the original request message. Redirect server: it receives the SIP request and maps the original address in the request to zero or multiple new addresses and returns them to the client. Registration server: it receives client registration requests to complete user address registration. Using

communication, IMS is attracting more and more attention. As one of the important members of the TD-SCDMA Industry Alliance, Putian Information Technology Research Institute is actively researching and developing IMS systems, and will finally provide complete IMS system solutions to operators.

not depend on any of these protocols.SIP does not provide services. Of course, SIP provides primitives for implementing different services. For example, SIP can locate a user and transfer a non-transparent object to his current location. If this primitive is used to transmit the session description is written to the SDP (Sessiong Description Protocol), for examp

1 IntroductionVoIP is the most representative of the development of the new generation of Internet age.One of the application technologies. As a signaling control protocol in VoIPThere is great potential for growth. Therefore, in order to better promote the development of VoIP servicesIt will be a major research topic to solve the problem of SIP traversing NAT. This article mainlyBased on the stun method, it aims at its inability to traverse symmetric

Request Message Request Line = method + space + request address + sip version number + blank line A request line is used as the starting line. The request line includes the method name, request URL, Protocol version number, and separated by spaces. Six request methods: Invite sends a call Session Request Ack invite request fina

/1.1. This behavior can be used for the "trace route (traceroute)" function to check the capabilities of individual servers in the message routing process by sending a series of ascending max-forwards value options requests. As a general UA behavior, if options does not respond for a long time, the transaction layer can return a timeout error. This indicates that the target is inaccessible and the query capability is unavailable. The options request may be sent by one end of the created dialog t

The HTML5 SIP client is an open-source client that fully utilizes JavaScript to integrate social networking (Facebook, Twitter, Google +), online games, and e-commerce applications. No extensions, no plug-ins, or necessary gateways. The video stack technology relies on WebRTC. Like Demo Video demo on the home page, you can easily implement real-time video/audio calls between Chrome and IOS/Android mobile devices. This client is a technology that can
