This article mainly introduces "what protocols will be used in the process of entering URL to display pages in browsers". In daily operation, I believe that many people have doubts about which protocols will be used in the process of entering URL to display pages in browsers. The editor consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful to answer the question of "which protocols will be used in the process of entering URL to display the page in the browser"! Next, please follow the editor to study!

Opening a web page can be divided into the following processes: 1 DNS parsing, 2 TSP connection, 3 sending HTTP request, 4 server processing request and returning HTTP message, 5 browser parsing rendered page, 6 connection ending.

OPSF-an implementation of the Open Shortest Path First link-state routing protocol; belongs to the Interior Gateway Protocol (IGP- Interior Gateway Protocol). The Dijkstra algorithm is used to calculate the shortest path tree, which uses the cost cost as the routing metric.

ARP-Address Resolution Protocol address resolution protocol is a network transport protocol that finds the address of the data link layer by parsing the address of the network layer.

In the Ethernet protocol, if a host in the same local area network wants to communicate directly with another host, it must know the MAC address of the target host. In TCP/IP protocol, the network layer and transport layer only care about the IP address of the target host. This leads to the fact that when IP protocol is used in Ethernet, the Ethernet protocol of the data link layer receives the data provided by the upper IP protocol, including only the IP address of the destination host. Therefore, a method is needed to obtain the IP address of the destination host according to its MAC address. This is what the ARP agreement does. The so-called address resolution (address resolution) is the process that the host translates the destination IP address to the destination MAC address before sending the frame.

In addition, when the sending host and the destination host are not in the same local area network, even if they know each other's MAC address, they cannot communicate directly and must be routed and forwarded. So at this time, the sending host through the ARP protocol will not be the real MAC address of the destination host, but a MAC address that can lead to a router outside the local area network. After that, all frames sent by the sending host to the destination host will be sent to the router and sent out through it. This situation is called delegated ARP or ARP agent (ARP Proxy).

ARP is not used in point-to-point links, and MAC addresses are not actually used in point-to-point networks, where the peer IP address has been obtained.

At this point, the study on "what protocols will be used in the process of entering URL in the browser to display the page" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it! If you want to continue to learn more related knowledge, please continue to follow the website, the editor will continue to work hard to bring you more practical articles!
