上海市的“上海档案信息网”（www·archly1s·Sh·cn）已应运而出,本文将就其区（县）级档案综合信息网建设中的若干问题进行探讨。 一、IP地址的选择 在互联网中,IP和TCP一起组成TCP/IP协议集合族,是互联网众多计算机之间交换信息的基础,互联网套用ISO的 OSI/RM（Open System Interconnectio——Refernce Model开放系统联结-参考模型）的分层概念,IP属于网层,TCP属于运输层。可以说,因为创造了具有TCP/IP功能的一套协议族,所以互联网才能如此迅猛地发展。TCP即传输控制协议（TransmissioControl Protocol）,即保证从一端到另一端应用程序间提供通信,并负责确认收到信息的顺序无误和内容正确无误,IP即网际协议（Internet Protocol）,全世界彼此
Shanghai’s “Shanghai Archives” (www. Archly1s · Sh · cn) has been shipped out, this article will be its district (county) level archives comprehensive information network construction of a number of issues to be explored. First, the choice of IP address In the Internet, IP and TCP together to form a TCP / IP protocol set, is the basis for the exchange of information between many computers on the Internet, the Internet sets the ISO OSI / RM (Open System Interconnection - Refernce Model Open System Link - reference model) concept of the hierarchy, IP belongs to the network layer, TCP belongs to the transport layer. It can be said that the Internet has been able to grow so rapidly because it has created a suite of protocols with TCP / IP capabilities. TCP is the Transmission Control Protocol (TransmissioControl Protocol), which guarantees communication between applications from one end to the other. It is responsible for confirming that the received messages are in the correct order and the content is correct. IP is the Internet Protocol,
