The layer-2 switching technology is relatively mature. The layer-2 switch is a data link layer device that can identify MAC locations in data packets.Address information, which is forwarded based on the MAC address, and the corresponding MAC addresses and ports are recorded in a local location.Address Table. The specific workflow is as follows:
1) when the switch receives a packet from a port, it first reads the source MAC address from the packet header so that it

Following opium and morphine, a more dangerous drug has come to the human world, and it is heroin. Heroin is a semi-synthetic opium drug and has a history of more than one hundred years. The pure heroin (commonly known as the white powder) mainly comes from the Golden Triangle (borders of Myanmar, Thailand, and Cambodia), some from Lebanon and Syria, and more from Pakistan. The color, precision, and purity of the product depend on the origin. White from Thailand, both pure and white from Leban

The layer-2 switching technology is mature. The layer-2 switch is a data link layer device that can identify the MAC address information in the data packet and forward it according to the MAC address, the MAC addresses and corresponding ports are recorded in an internal address table. The specific workflow is as follows:
(1) When the switch receives a packet from a port, it first reads the source MAC address from the packet header, so that it knows the port on which the machine with the source M

2-3-4 is a type of B tree with a level of 4. It is a self-balancing data structure that can be searched, inserted, and deleted in O (lgn) time. Here N is the number of elements in the tree. 2-3-4 trees are equivalent to the red-black tree, that is, each red-black tree can be
The development of switch technology is very rapid. From the third-layer switch technology to the fourth-layer switch technology, the experience is very short, meeting more needs of users. When I first heard the word "Layer 3", I had some puzzles. The subsequent concepts of Layer 4 switching and Layer 7 switching are even more confusing. In fact, in strict terms, exchange means the connection between the so
As can be seen from the analysis of the 4th section, binary search tree is a very good data structure, can quickly find a given keyword data items, and can quickly insert and delete data items. But binary search tree has a very troublesome problem, if the tree is inserted in random data, then the performance is good, but if the insertion is ordered or reverse-order data, then the two-fork search tree execution speed becomes very slow. Because the binary tree is unbalanced when inserting values i
