Currently, there are many kinds of router protocols, and many people may not know how to use the Router Protocol to minimize network interruptions. It doesn't matter. After reading this article, you will certainly have a lot of GAINS, I hope this article will teach you more things. As we all know, to obtain a high network duration, you need to use a master router and a backup router with a hot fault recovery function and different network paths. But t

The routing information protocol, as the name suggests. A standard technology that manages the data distributed by a route based on the routing information protocol. We will summarize the features of this Protocol. Before that, let's take a look at its basic information. The routing information protocol was originally designed for Xerox PUP (PARC universal protocol). the routing information protocol was collectively referred to as "GWINFO" in the Xerox network system protocol in 1981 ", it was a

In a network structure, the functions supported by the routing protocols in various network forms are different, and the connotation protocols are also different. Now we will introduce some features of the wireless communication routing protocol. And the Routing Protocol in wireless sensors. Wireless Communication Routing Protocol Compared with traditional wireless communication networks, traditional wirele

Basic protocols running on Ethernet 1. Introduction A network listening tool was compiled some time ago. To analyze captured data packets, you must be familiar with various network protocols. I am suffering from the fact that there are few articles on the Internet that focus on this aspect, and most of the books are not carefully explained. A small number of books devoted to network

The L3 address types in ARP packets include unicast, broadcast, and multicast, which are stored in the neighbor structure (neigh-> type ), you can use inet_addr_type to determine the address type. ARP processes each type: unicast, which is a common solication request for ARP resolution. Broadcast: arp maps L3 broadcast addresses to L2 broadcast addresses related to specific devices. Multicast: ARP uses the arp_mc_map function to export L2 multicast addresses from L3 multicast addresses. ARP does

We know that the tcp ip protocol stack includes many protocols. So let's take a look at the functions and functions of the protocols here. Now let's make an inventory check to help you summarize it and hope it will help you. 1. bsd tcp ip protocol stack BSD stack is the starting point of other commercial stacks in history. Most professional TCP/IP stacks embedded in VxWorks are derived from the BSD stack. t

Description of some network protocols DICT: a dictionary server protocol. Dict servers and clients use TCP port 2628 FILE: Mainly used to access files on local computers, just like opening a file in Windows Explorer. FTP: (File Transfer Protocol, FTP) is the Protocol for transferring files from two computers on the TCP/IP network. FTP is one of the earliest protocols used on the TCP/IP network and the INTER
