随着用户数的急剧增加和对业务多样性要求的提高,网络的安全性问题日益突出。由于传统认证方式对校园网中用户数据包进行繁琐的处理会造成网络传输瓶颈,而通过增加其他网络设备来解决传输瓶颈的问题,则势必会造成网络成本的提升,因此无法满足用户对网络安全性、高效性和低成本的要求。IEEE802.1x协议的诞生很好地满足了用户在这些方面的需求。IEEE802.1x协议通过对认证方式和认证体系结构进行优化,有效地解决了传统PPPoE和Web/Portal认证方式带来的问题,消除了网络瓶颈,减轻了网络封装开销,降低了建网成本,从而成为当前校园网选型的一个热点。 IEEE802.1x又名为基于端口的访问控制协议(Port based network access control protocol),它源于
With the rapid increase in the number of users and the increasing demand for business diversity, network security has become increasingly prominent. Traditional authentication methods cause a bottleneck of network transmission due to cumbersome processing of user data packets in the campus network. To solve the problem of transmission bottlenecks by adding other network devices, network costs are bound to increase, and therefore, the network security can not be satisfied. Sexual, efficient and low-cost requirements. The birth of IEEE802.1x agreement to meet the user’s needs in these areas. The IEEE802.1x protocol effectively solves the problems caused by the traditional PPPoE and Web / Portal authentication modes by optimizing the authentication mode and authentication architecture, eliminates bottlenecks in the network, reduces the network encapsulation overhead and reduces the cost of network construction, thereby Become a hot spot in the current campus network selection. IEEE802.1x, also known as Port based network access control protocol, is derived from
