The Application of Multi-layer Switching in the Design of Broadband Firewall System 多层交换(MLS)技术在宽带防火墙系统中的应用
This requires network devices to have various functions ( e.g. multi-layer switching, security processing and traffic management ) as well as powerful protocol processing capability and programmability, so that the novel network services can be quickly deployed and configured in these network devices. 智能化处理不仅要求网络设备具有多层交换(MLS)、安全处理和流量管理等功能,还必须具有强大的协议处理能力和灵活的可编程性,能够快速适应新型业务的添加和配置。
Multi-protocol label switching ( MPLS ) is a multi-layer switching technique that utilizes characteristics of layer 2 switching and of IP routing. By inserting labels into IP packet, routing forwarding in MPLS depends on the labels. 多协议标记交换(MPLS)技术是综合利用网络第二层交换技术的有效性和第三层IP路由的灵活性等优点而产生的多层交换(MLS)技术。
