| 摘 要： | 传统以太网尽管能够显著地利用带宽,但是并不能抑制广播报文的扩散,广播报文仍然能够扩散到整个网络中去.同时,网络中的主机也不能够根据需要将其划分至相应的逻辑子网中,因此,网络的结构缺乏灵活性.而采用VLAN技术的以太网可以很好地解决以上问题.首先讨论了802.1Q VLAN的帧格式及Linux下实现802.1Q VLAN所需要的数据结构,然后详细讨论了Linux下802.1Q VLAN的数据处理流程.最后给出了802.1Q VLAN在校园网中的应用分析.

| Abstract: | In spite of utilizing network bandwidth effectually,the traditional Ethernet still can't prevent broadcast packet from spreading everywhere on the network. At the same time, it can' t be assigned to its logic subnet by the host of network according to the requirements because the structure of network is short of flexibility.However,the 802.1Q VLAN technology will solve this problem easily.The formats of 802.1Q VLAN frame and data structures needed for 802. 1Q VLAN implementation based on linux are discussed,then the following section and the processing flow charts of 802.1Q VLAN are also discussed in detail.The application analysis of 802.1Q VLAN in the campus network is presented in the end. |
