There are many other things worth learning about the Router Protocol. Here we mainly introduce the details of the CLNS Router Protocol. The full name of CLNS is "Connectionless Network Service" (Connectionless Network Service ), it is a layer-3rd service designed for layer-4 oSI protocol-"connectionless network protocol" (CLNF. Here, we do not plan to run any 0SI protocol (9th rows )!

The routing protocol is used to exchange routing information between routers. With the continuous development of network technology, the more complex the network, and the emergence of new routing protocols. Through the routing protocol, the router can dynamically share information about the remote network. The routing protocol can determine the optimal path to each network, and then add the path to the routing table. The dynamic routing protocol can automatically detect remote networks. As long

If yes, the vro。 forwards the route according to the corresponding static route forwarding group. Otherwise, the vro searches for the dynamic route. -- Dynamic Routing Protocols are divided into internal gateway protocol (IGP) and external Gateway Protocol (EGP) based on whether they are used in an autonomous domain ). The Autonomous Region refers to a net

Aspect-oriented programming (AOP) is a programming paradigm invented by Xerox PARC in the 1990s s of the Xerox Corporation, it allows developers to better separate tasks that shouldn't be entangled with each other (such as mathematical operations and Exception Handling. The AOP method has many advantages. First, because the operation is more concise, the performance is improved. Second, it ma

Judging from the stability of the model, it is also higher than the structural method.Disadvantage: The developed software redundancy part is many, from the efficiency aspect, is lower than the structure method; And because of its encapsulation, so that the internal control of the system is not clear, to the future maintenance work to increase the difficulty.b) Development of object-oriented

Ethernet technology is based on Ethernet frames, also known as standard Ethernet frames (ARPA), that is, Ethernet II frames (originally known as DIX, the initials of the three launch companies Intel and Xerox are combined ). The frame format is as follows:
