Problems solved by technology

[0008] The present invention provides a naming service scheme for a network communication system and a communication method realized by using it, so as to solve the problem of naming resolution between SIP URI, HI / HIT, and transmission address when the HIP protocol is integrated in a P2P-SIP system. Naming services such as user registration, update, and search are realized on the DHT overlapping network in a completely peer-to-peer manner

Embodiment Construction

[0034] The present invention is mainly aimed at the P2P-SIP network telephone system oriented to the IP network, which has the characteristics of free and dynamic unmanagement, and users can freely join or exit, and independently provide or use services. System users can independently select and register a SIP logo like "sip: username@example.org" under the domain name, and use HI / HIT as the logo to implement HIP communication. The present invention implements SIP URI to HI / HIT and IP, port, transmission protocol registration, update, search and other naming services in a fully reciprocal manner on the DHT overlay network. It also needs to provide a security control mechanism in an open network without a center. And prevent attacks such as logo theft.

[0035] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the following are the system composition, basic naming service scheme, security control mode of node identification, acce...

Abstract

The invention relates to an IP network multimedia communication technique, in particular to a naming service proposal applied to a network communication system and a communication method realized by utilizing the proposal, which aim at solving the name binding problem of SIP, URI, HI / HIT and transmission address when a system integrates Host Identity Protocol (HIP), and realize such naming services as registration, updating and search of a user in a complete peer-to-peer manner on a Distributed Hash Table (DHT) overlay network; by using the proposal, the user uses an SIP URI for binding one or more HIs; each HI is used for binding one or more transmission addresses; the user can use the SIP URI and a private key for logging the system and conducting SIP call according to the HI / HIT, thereby finishing HIP base exchange continually and establishing a safe media data transmission channel; the distributed safety mechanism can effectively ensure the uniqueness of the verification of the user, prevent such attacks as service refusal and protect the storage and updating of name binding; and the invention utilizes the DHT overlay network to realize naming service and the transmission of standard SIP signaling information, is easy to realize and arrange and causes the user to enjoy simple and safe network communication services.

Description

Technical field [0001] The present invention relates to a multimedia communication technology of an IP network, in particular to a naming service scheme used in a network communication system and a communication method realized by it. Background technique [0002] At present, Internet-based VoIP systems have been widely used, and Session Initiation Protocol (SIP) is often used as the signaling protocol for multimedia sessions. SIP uses a C / S structured message delivery mechanism at the application layer, and realizes user positioning, message forwarding and receiving, and call control through servers such as registration, proxy, and redirection. The traditional SIP-based VoIP system uses the C / S structure. Each VoIP terminal needs to be registered to the SIP server in the domain. The communication between users needs to be managed and routed by the SIP server, so it is necessary to deploy and maintain a dedicated SIP Server, and there are problems such as single point of failure ...
