The system switching capability and processing capability of a high-speed router are different from those of a general router. At present, the high-speed Router backplane switching capacity should reach 40 Gbps or above, and even if the system does not provide OC-192/STM-64 interface, this interface must also be supported without upgrading the existing interface card and general-purpose parts in the future. In terms of device processing capability, when the system is running at full capacity, al

route consists of two basic actions: determining the optimal path and transmitting information through the network. In the routing process, the latter is also called data) exchange. The switching is relatively simple, but the selection path is complicated. Basic routing knowledge: Route Selection Metric is the Metering Standard used by routing algorithms to determine the optimal path to the destination, such as the path length. To help route selecti

unavailable. The OSPF protocol avoids the generation of self-loops from the fundamental (algorithm itself. Using distance vector protocol (RIP) and other protocols, self-loop routing is inevitable. In order to improve these dynamic routing protocols, we can only take a number of measures to reduce the probability of occurrence during the lifetime of the Self-loop, and reduce the impact scope and time after the occurrence of the Self-loop. In today's increasingly scarce IP (IPV4) addresses, it i

, such as the cumulative gain (DCG) of discounts. These metrics are popular because they support hierarchical correlations that are commonly used to determine whether a Web document is relevant or not. While it is important to support hierarchical correlation, there are other important factors that should be considered in the evaluation criteria.An important factor that DCG cannot explain is how the user actually interacts with the document ranking list. This

, it is very important for a routing protocol to support variable-length Subnet Mask (VLSM) to save IP Address resources, OSPF can meet this requirement. In a network using the OSPF protocol, if OSPF is used to calculate two routes with equal cost (Metric) to the same destination, the protocol can add these equivalent routes to the routing table at the same time. In this way, load balancing or load balancing can be achieved during forwarding. In terms

interfaces at the wire speed without affecting the traffic type. One metric: Throughput Throughput is the packet forwarding capability of the router. Throughput is related to the number of vro ports, port rate, packet length, packet type, route computing mode distribution or concentration), and test methods. throughput generally refers to the ability of the processor to process packets. The packet forwarding capability of a high-speed router must be

Hops : hop count metric can simply record the hop count of the router.? Bandwidth: The bandwidth (Bandwidth) metric will select a high-bandwidth path rather than a low-bandwidth path.? load: The load measure reflects the amount of traffic that is tak
