Networking Solutions for high-end routers with multiple services

Throughout the Internet research field, router technology has always been at the core position, and its development history and direction have become a microcosm of Internet research. In the Internet, routers, as the main node devices, are the key devices for connecting networks and the hubs of interconnected networks. The Hub function is to establish connections between different networks. The vro system forms the main context of the TCP/IP-based Internet, and is the backbone of the Internet.
A router is in a critical position in an interconnected network because it is at the network layer and has the following two functions: on the one hand, it shields the technical details of the underlying network, DDN, FDDI, and Ethernet can be used across different physical network types, so that all types of networks are unified as IP addresses. This Consistency makes communication between users across the world possible; on the other hand, the entire interconnected network is divided into logically independent network units, so that the network has a certain logical structure. At the same time, the router is also responsible for flexible routing selection of IP packets, data is forwarded to the destination segment by segment, making communication between users around the world a reality.
With the continuous development of computer networks, the rapid increase of network bandwidth, and the improvement of users' service quality requirements, as the core device of the Internet, the router technology is also facing new changes. Especially in the aspect of high-end routers, it has become an irresistible trend for its development in the Multi-Service direction. Cisco, Huawei 3COM, Juniper, Avici, and D-Link are representative of domestic and foreign equipment vendors with high business levels.
