Description

1231695 V. Description of the invention (1) [Technical field to which the invention belongs] The present invention is a routing protocol device that integrates an Internet telephony server, and particularly relates to a Sess i on initiation Protocol (hereinafter referred to as SIP) ) The basic architecture, the invention of the SIP network telephone server (caH Server) integrated routing protocol device. [Previous technology] According to the advancement of Internet technology, the flow of information has become more convenient, and the borderless form of the Internet has also drawn into the distance between people. There are many conveniences and Cheap communication methods are realized through the Internet, such as Internet telephone (v〇ice 〇ver Internet Protocol, hereinafter referred to as v〇ip) technology, which refers to the IP-like voice over the Internet Communication can save a lot of phone call costs. The current Internet is using TCP / IP (Transmissi〇n

Control Protocol / Internet Pr〇t〇c〇1) as a communication protocol for packet data transmission on the network, each computer connected to the Internet has a unique IP address, so that data packets can be transmitted. The network itself is structured by many different networks, such as the US domestic network system, university internal systems, etc., so between many different network systems, routers call "^" Connected and send the data packet from a certain network system to the road system until the data packet reaches the destination network system. , ’A router can choose an optimal path from many possible network paths

Page 5 1231695 V. Description of the invention (2) The routing protocol is used to transmit data packets, and the routing protocol is the routing protocol (Routing Protocol). Common routing protocols include RIP (Routing Information Protocol) and 〇SPF ( Open

Shortest Path First) rIP is suitable for smaller network systems, while 0SPF has greater flexibility and can be used in large network systems. Therefore, most devices with a routing protocol function are located at the SP service provider, the provider's office that provides broadband connections, or the data room or information center of a large company or unit with multiple network connections. In addition, there is a new protocol called “Initiation Protocol (IP)” for IP phones derived from broadband networks. It focuses on the Internet and The new technology of the public telephone network integration environment, the main operation mode is to transmit the voice analog signal (Voice) from a near-end telephone to the router, convert its audio signal into a data packet (j) ata Packet), and pass IP The network transmission method is transmitted to the remote router. The remote router then converts the data packet back into a voice analog signal and then transmits it to the phone. In this way, it can be connected to all over the world through the open Internet, allowing users to Long-distance telephone communication is then carried out through the traditional public telephone network (PSTN). This SIP is an application layer (Application Layer) protocol in the seven-layer architecture of the Open System Interface (OSI), like the Cl i net-Server architecture of the HTTP protocol, and can use packet data available in HTTP for packet processing. The command and status are transmitted in text mode, so this SIP is very suitable for the transmission architecture of a wide area network. Therefore, in this SIP, in addition to the user terminal, proxy software (User
