Description: SIP是一个应用层的信令控制协议，用于创建、修改和终止一个或多个参与者的会话。这些会话可以是Internet多媒体会议、IP电话或多媒体分发（例如语音信箱）。会话的参与者可以通过组播(multicast)、网状单播(unicast)或两者的混合体进行通信。更为详细的SIP介绍，可参考相关的网站和书籍，如SIP FORUM等-SIP is an application-layer control protocol signaling for creating, modification and termination of one or more participants in the conversation. These sessions can be multimedia Internet, IP telephony and multimedia distribution (such as voice mail). Session participants through multicast (multicast), mesh unicast (Unicast), or a combination of both mass communications. More detailed SIP, can refer to the relevant Web sites and books, such as SIP FORUM Platform: |

Description: 文件传输协议FTP是基于TCP / IP的应用层协议,其主要功能是提供文件的共享、支持远距离计算机间接或直接连接、保护用户不因各类主机文件存储器系统的差异而受影响、进行可靠且有效的数据传输等,应用非常广泛。但是传统的FTP有不少的安全漏洞,例如明文传输、缺乏对数据的机密性和完整性保护,对通信双方也没有可靠的认证措施等。针对FTP的安全漏洞,近年来也出现了一些不需要对F IP协议自身做完全更改的协议扩展模块,如FTP SSL /TLS Extension。SSL ( Secure Sockets Layer)是用于对TCP / IP数据流进行加密的协议,同时还包括了身份认证和数据完整性校验等内容。显然,基于SSL /TLS的FTP克服了明文传输的致命弱点,但是无可否认的是,在开放式的互联网环境下FTP服务器受到恶意攻击的可能性还是很大,而且协议数据的安全性还是未得到保障。安全的本质是在信息的安全期内保证其在网络上流动的或
者静态存放时不被非授权用户非法访问,但授权用户却可以访问。基于这一概念,本文在SSL 的基础上设计了一个安全FTP系统,从认证、传输、存储三个方面大大提高了FTP的安全性。-FTP File Transfer Protocol is based on TCP/IP application layer protocol, its main function is to provide file sharing, remote computer support to connect directly or indirectly, to protect users from all types of hosts file memory system affected by the difference between, for reliable and effective data transmission and so on, a wide range of applications. Traditional FTP but there are a lot of security vulnerabilities, such as express delivery, lack of data confidentiality and integrity protection, the two sides of the communication did not credible certification measures. FTP for security vulnerabilities in recent years, there have been some F IP protocol does not need to completely change their agreement to do the expansion modules, such as FTP SSL/TLS Extension. SSL (Secure Sockets Layer) is used for TCP/IP data stream is encrypted agreement also includes authentication and data integrity checking and so on. Obviously, based on SSL/TLS for FTP transmission to overcome the Platform: |

Description: SIP协议是一个用于建立，更改和终止多媒体会话的应用层控制协议。它是IETF多媒体数据和控制体系结构的一部分并大量借鉴了成熟的HTTP协议，具有易扩展、易实现等特点，因此非常适合用于实现基于因特网的多媒体会议、IP电话等系统。本系统使用Java实现了一个简单的VOIP电话应用系统。-SIP is a protocol for the establishment, modification and termination of multi-media session control protocol application layer. It is the IETF multimedia data and control architecture and a large number of reference as part of the HTTP protocol a mature, easy expansion, easy to achieve such characteristics, it is very suitable for the realization of Internet-based multimedia conferencing, IP phones and other systems. The system uses Java to achieve a simple VOIP phone applications. Platform: |

Description: 本文在研究IEEE802.16e协议和SIP协议的基础上，提出了利用
SIP解决IEEE802.16接入网络中端到端切换的新方案。该方案采用跨
层切换的设计思想，联合MAC层和应用层SIP协议，在底层链路切换
的同时，完成应用层会话的修改，加快了切换过程，减少了切换时延，
提高了切换成功率。本文基于NS2仿真平台，完成了相应的仿真平台
搭建过程，实现了SIP协议模块和WiMAX协议模块的融合，扩展了SIP
协议模块的部分消息，最终在基于SIP协议模块和WiMAX协议的统一
NS2平台上实现了基于WiMAX接入、支持SIP扩展功能的SIP会话建
