Description

一种基于因特网的点对点通讯系统及动态IP地址获取方法技术领域本发明属于计算机通讯技术领域,尤其涉及一种基于点对点(Peer to Peer, P2P)通讯时,动态网络IP地址的获取方法。 A time-TECHNICAL FIELD The present invention pertains to computer communication technologies, and in particular relates to point-based (Peer to Peer, P2P) communication, the IP address obtaining method of obtaining dynamic network an Internet-based peer communications system and a dynamic IP address. 背景技术当前,P2P技术作为新兴的基于网络(INTERNET)的通讯方法正得到越来越广泛的采用。 BACKGROUND Currently, P2P technology as a new network (INTERNET) communication based on being more widely adopted. 该种P2P技术能根据用户的网络地址(NA)直接进行基于网络的数据传输,从而充分利用了网络的分布性特征。 This kind of technique can P2P (NA) direct network address of the user based on a data transmission network, to take full advantage of the characteristics of the distribution network. 该种技术中,一般采用IP地址作为NA。 The techniques generally employed IP address as NA. IP地址现分为两种:静态IP地址和动态IP地址。 IP address is now divided into two types: static IP address and dynamic IP addresses. 由于静态IP地址会造成IP地址资源的极大浪费,因此,通常采用的是动态IP地址。 Because the static IP address IP address will cause a great waste of resources, therefore, usually a dynamic IP address. 由于上网设备每次新登录网络时,动态IP地址均会发生变化,因此就会造成在P2P技术中,用户无法以动态IP地址作为其上网设备的固定标识,而是需要以其它始终不变的地址内容作为上网设备的标识,由该不变的地址内容再进而获得NA,根据NA进行P2P通讯。 Because Internet device each time a new log onto the network, dynamic IP address will change, so will result in P2P technology, the user can not dynamic IP addresses to identify the Internet as their fixed equipment, but requires otherwise always the same Internet address content as identification device, by the content of the address again and then get the same NA, the P2P communication according to NA. 在现有4支术中,存在以下几种P2P的通讯实现方法:1 、上网设备以用户定义的电子地址作为标识进行P2P通讯: 在该方法中,用户以利于记忆的原则定义电子地址作为其上网设备的标识。 4 in the prior art, there are several P2P communication implemented method of: 1, an electronic device to the Internet address of the user-defined identifier for P2P communication as: In this method, the electronic address of a user memory to facilitate principles defined as its Internet identifies the device. 该电子地址可采用自然语言、地理位置、个人喜好等规则进行定义。 The electronic address can be used in natural language, geographic location, personal preferences and other rules defined. 在P2P 通讯过程中,利用地址解析服务器对用户的电子地址进行解析,从而获得相应的动态IP地址,具体包括:上网设备每次登录网络均将其电子地址和当前网络地址,即当前动态IP 地址成对存入地址解析服务器中,在P2P通讯过程中,用户在上网设备上填入电子地址,地址解析服务器对该电子地址进行解析,获得当前NA并传送 In the P2P communication process, using the ARP server to the user's electronic address is parsed to obtain the corresponding dynamic IP addresses, including: network access device every time you log all its electronic address and the network address that the current dynamic IP address pairs stored in the address resolution server, the P2P communication process, the user fill in the electronic address on the Internet devices, address resolution server parses the electronic address, and obtain the current transfer NA

给上网设备;上网设备获得当前NA后,根据NA进行P2P的通讯。 Access to equipment; access equipment obtained after the current NA, P2P communication according to NA. 2 、以数据为中心的P2P通讯方法:在美国Gartner的一份报告中,^是出了基于以数据为中心的P2P模型的内容网络解决方案,这种模型基于动态索引的服务器地址,当客户连接到网络的时候,服务器扫描客户的特定存储区,并把相关的数据索引加到服务器中。 2, data-centric P2P communication method: Gartner said in a report in the United States, ^ is a P2P model based on data-centric content network solutions that address the dynamic model of server-based index, when customers when connected to the network, the client server scans a specific storage area, and the relevant data is added to the index server. 通信双方同时登录到某个提供服务的主机上,由该主机建立双方的间接连接,网络电话、网络寻呼、网络游戏大都使用这一方法。 The two sides also communicate to log on to a host to provide services, founded by the host of both indirect connection, Internet telephony, paging networks, online games, most use this method. 在这个模型中,查找具体数据的用户可以从头到尾地4叟索整个服务器,然后与其它客户直接连接,对数据直接访问。 In this model, a user can find the specific data from start to finish the entire search server 4 elderly, and directly connected to the other client, to access data directly. 方法1和方法2虽然在获得动态IP地址的方式上有所不同,但是均需要借助服务器方可完成P2P通讯。 Methods 1 and 2, although different in the way they obtain dynamic IP addresses, but require the server to be completed by means of P2P communication. 具体来说,方法1中通过地址解析服务器解析电子地址获得NA,根据NA进行P2P通讯;方法2中则是通过在服务器中的检索实现地址的获得并建立连接实现P2P通讯。 In particular, a method by electron resolve ARP server address obtained NA, NA according to the P2P communication; is the realization of the address obtained by searching in the server 2 and establishes a connection method to realize P2P communication. 由此可见,以上两种方法在P2P通讯过程中均没有摆脱服务器的限制,并未实现真正意义上的点对点传输。 Thus, the above two methods are not free from restrictions in the P2P server communication process, point to point transmission has not been achieved in the true sense. 在现有技术中,通过特定IP字段的扫描搜索获取动态IP地址的方法也被采用于P2P的连接方式中。 In the prior art, obtaining a dynamic IP address by searching for a particular IP field scanning method is also employed in the P2P connection. 虽然这种方式并不依赖中心服务器,但是作为一种盲目的穷尽搜索会给网络带来巨大的负担。 Although this approach does not rely on a central server, but as a blind exhaustive search the network will bring huge burden. 同时,很难与希望保持联系的人建立稳固的连接,反而出现大量不需要的地址。 At the same time, it is difficult to keep in touch and hope to establish a solid connection, a large number of addresses but there is no need. 发明内容有鉴于此,本发明的主要目的在于提供一种基于因特网的P2P通讯的动态IP地址的获取方法。 SUMMARY OF THE INVENTION Accordingly, the main object of the present invention is to provide a method for obtaining a dynamic IP address based on a P2P communication as the Internet. 该方法采用分布的方法获取IP地址。 Methods The distribution of IP address acquisition. 此外,本发明的目的还在于提供应用该动态IP地址的获取方法的系统。 Further, the object of the present invention is to provide a method for the system to obtain a dynamic IP address of the application. 本发明的基于因特网的点对点通讯系统包括: 多个上网设备,每个上网设备与网络和各自的通讯终端相连接;
