基于广播隔离的IP城域网技术体系优化策略探究与实施

Research and Implementation of Optimization Strategy of IP Metropolitan Area Network Technology System Based on Broadcast Isolation

为应对广播风暴、信息安全等问题,对徐州IP城域网现状实施高效优化方案。该方案不仅满足客户需求,还满足系统的刚性需求,并保证技术合理性和业务发展的灵活性。创造性地将常用于无线网中的Option43用在IP城域网中,实现不同业务的网络区分。并通过Virtual Bridge Port+三层子接口的方式,实现二三层接口业务共存和相互隔离,减少了广播风暴、信息安全等风险。

In order to cope with broadcast storms,information security and other problems,an efficient optimization solution is implemented for the current situation of Xuzhou IP MAN.The solution not only meets customer demands,but also satisfies the rigid demands of the system,and ensures technical rationality and flexibility of service development.Option43,which is commonly used in wireless network,is creatively used in IP MAN to realize network differentiation for different services.And through the Virtual Bridge Port + Layer 3 sub-interface,it realizes the coexistence and mutual isolation of Layer 2 and Layer 3 interface services,which reduces the risks of broadcast storm and information security.
