internet protocol tcp ip properties

Over the past few days, I have been browsing the TCP/IP protocol stated vol1 (hereinafter referred to as distributed strated) and internetworking with TCPIP vol1. I found that many key knowledge points I have learned are almost forgotten, I was a little surprised at my forgetting speed. So I recorded some points of interest. Hope you can do it and learn new thing

One, TCP/IP protocol1. TCP/IP protocol including TCP, IPS and UDP2. Domain name is converted to IP address via DNS server3, LAN can be IP or

, so the rtrequest function is called and the number of references is Rtm_add, the flag is rtf_up and rtf_cloning. Each IFADDR structure has a pointer to a function (Ifa_rtrequest member). This function is invoked on its own initiative when creating or deleting a route table node, and for all Ethernet devices, In_ifinit points the pointer to the Arp_rtrequest function. Therefore, when the call route function creates or deletes a route table node for ARP , Arp_rtrequest is always called, and whe

. If no matching node is found, a new ARP node is created. 2. arptfree uses the rtm_delete command as a parameter to call rtrequest and delete the route table node of the corresponding ARP node. In addition, ARP commands manipulate ARP high-speed cache by sending and receiving Route packets on the route plug-in. ARP publishes route information with the rtm_resolve, rtm_delete, and rt_get commands. The first two parameters are used to call rtrequest, and the third parameter is used to call rtallo

The socket can support different transport layer protocols (TCP or UDP), which is a TCP connection when the connection is made using the TCP protocol.The socket is an abstraction layer between the application layer and the transport layer, which abstracts the complex operations of the TCP/

The tcp ip protocol is the basic transmission control protocol that must be used during network construction. How can we conduct modulation and analysis in this aspect during the networking process? First, we need to know some important protocols in the tcp

These things will not be confused, because they are not a level of East, now think about the early I feel some do not understand because the agreement is in the abstraction layer is not clear, the knowledge should be from the bottom solid walk.First, the agreement is not big, the agreement is the two sides agreed to abide by the norms, only that. The data transmission between the Internet is on the Ethernet, and it needs to do some processing before i

Check the computer and find the problem:1. The computer cannot automatically obtain the IP address2. An error is reported when a domain is added after the IP address is set manually.It is estimated that the TCP/IP protocol is damaged. You can reinstall it to solve the proble

For the tcp ip protocol stack, we have already talked a lot about its principles. However, the principle is not enough. In this regard, we will give you an actual operation example to explain, first, let's take a look at the TCP/IP proto
