摘要
简要分析了目前以太网平台上VLAN实现技术的局限性,提出基于服务的虚拟局域网管理策略,建立了一套较完整的基于服务的虚拟局域网(VLAN)体系结构VASS·通过仿真实验及UDP视频数据流传输实验,VASS较好地控制了广播通信量,大幅度降低了局域网需经过路由的数据量,提高网络系统抵御广播风暴的能力·同时采用该模型后网络资源的分配和使用都较以前灵活、有效,提高了网络的通信服务效率·
Drawbacks and limitations of previous VLAN implementation methods in Ethernet environment are briefly analyzed. Then a kind of VLAN administration strategy based on service is proposed to set up the VASS architecture, i.e.,a fairly integrated VLAN architecture based on service. A simulation and UDP video transmission experiment were therefore conducted and the results showed that VASS can properly control broadcast traffic and decrease LAN route traffic flow to a great extent so as to improve network system's ability to withstand broadcasting storms. In addition the distribution of network resource adaptable to the model is more flexible and effective than before with the network service efficiency improved.
