随着计算机网络化的迅速普及,单机环境已经被局域网环境迅速取代,计算机联网技术及方法也飞速的发展。局域网结构在经历了一段时间的发展后,各种结构的优点及缺陷日益明显,在安全性、易用性、高效性等要求不断提高的今天,研究一种新型的局域网结构及技术方案成为我们亟待解决的问题。 With the rapid popularization of computer network, stand-alone environment has been quickly replaced by the LAN environment, computer networking technology and methods are also rapid development. LAN structure has experienced a period of development, the advantages of various structures and defects are increasingly evident in the security, ease of use, high efficiency and other requirements continue to improve today to study a new type of LAN structure and technology programs to become our Problems to be solved.
