sends each packet received to all output lines except for the line that the packet arrives at. In the future there will be multiple groups of replicas arriving at the destination, the first to arrive, probably the "best" path.3. Traffic-based routing algorithmsConsidering both the topological structure and the network load, the average data flow between each pair of nodes is relatively stable and predictable, and the average packet delay can be obtai

table: A route table contains a series of table items, including the preceding three elements.The layer of the routing framework: the routing is divided into two elements. The first level is the generation of route table items, a
relationship between the IP address and the MAC address of Host B in its own ARP cache table. At this point, the switch has learned the MAC address of host A and Host B.
Detailed routing TableRouters are responsible for communication between different networks, it is an important device in today's network, it can be said that there is no router on the internet today. There is also a

Please don't! Many people say so, including me.The Linux kernel has already removed the hash routing table, and now it's only trie, but I'd like to have some metaphysical discussions on both of these data structures.1.hash and Trie/radixhash and tire can be unified together. Multiple items with the same hash value have a common feature, how is this feature extracted? This is undoubtedly the work of the hash
The topology is as follows:
The simple way to provide Internet access for the CE router is to let the interface on the PE connected to the CE router be in the global routing space, the PE router has a VRF interface pointing to the CE router, and an interface to the CE router but not the VRF. Then the CE router can send VPN traffic to the VPN interface and send the Internet traffic to the Global routing
according to the "instructions". Similar to the address information table of the vswitch, the place where the "indication" is stored on the vro is called a forwarding table. 3. Relationship between two tables 3. 1. Contact
The forwarding table directly acts on data packets, while the route table is the basis for gene

For general operating systems such as Linux, the routing table cost is mainly concentrated on "longest mask match", because in the process of IP routing, the input is only a IPv4 address, that is, th

And, thanks to the efficient use of the CPU cache, the MMU degenerated into a slow path that will only be enabled when the cache is not hit, and by locality we know that most of the time, the flow of execution is fast ... It seems that the idea should be changed a bit.I know that the DXR algorithm is the way it is, so it's not my personal nonsense. But I play with the DXR a little bit different .

It is often asked on the forums whether the trie algorithm is used to save the routing table or the hash algorithm. So first of all, I need to understand how much routing table you want to keep. The simple answer is as follows:Small amount: hash algorithmMass: Trie algorithmHowever, this answer will be very amateur, re
