摘　　要：介绍了安全协议IPsec的不足,并针对IPsec无法解决的安全隐患提出了一种新的网络安全协议—有限制发送协议。在新的协议中,如果主机向网络发送大量的具有攻击性的数据包时,其发送权利将会受到限制,从而保证网络的安全。采用了OPNET仿真软件对新的协议进行了仿真,仿真结果表明,采用新的协议时,网络性能要好。采用新的协议时,平均HTTP响应时间为0.013 s;不采用新的协议时,平均HTTP响应时间为0.032 s。Firstly, IPsec is introduced and its shortage is analyzed. Secondly, as a new Protocol, the limited transmission protocol is put forward. In the new protocol, if many data packets are transmitted into the network by a computer, the computer would be limited to transmit data packets in order to assure the security of the network. Then, the performance of the new protocol is simulated with OPNET software, which shows the new protocol could enhance the network performance. For example, the average of HTTP object response time is 0. 013s when the new protocol is adopted in the network. When the new protocol is not adopted, it is 0. 032s.
