Protocol.
These network protocols perform various functions required for communication between the user applications on the source and target devices. These functions may vary greatly between different protocols. The network protocol occurs on the layer 4 of the OSI reference model: transport layer, Session Layer, presentation layer, and application layer.
The terms routed protocol (the protocol that can be routed) and routing protocol are often confused. Routed protocol is routed in the Networ

In the network, the use of various hardware will cause a high temperature environment. So we can use the hot backup routing protocol HSRP) for configuration. So what is the hot backup routing protocol HSRP )? The Hot backup routing Protocol HSRP, Hot Standby Router Protocol) is a routing Protocol that allows hosts on the Internet to use multiple routers as a single virtual Router) to maintain the connection, in this way, even if the first hop router fails, other routers can be enabled immediatel
There are many small details about the routing protocol, which deserves our attention. There are also many categories that indicate the different functions of different routing protocols. Now we will talk about the routing information protocol. For more information about the specific functions and features of this protocol, refer to them.
The routing information protocol was originally designed for Xerox PUP (PARC universal protocol). In 1981, the rou
In this article, we compile the echo server sample program. when the client data is received, the server sends the data to the customer without processing, and uses TCP connection and port 8080 for design.

loopback protocol and the Ethernet protocol at the network link layer.Ethernet (ether-net) is defined as a standard published by Digital Equipment Corp., Intel Corp., and Xerox in 1982, which uses a standard known as csma/ The access method of the CD. The standard set of 802.3 (which is also defined in 802.2) provided by IEEE802 also provides a CSMA/CD standard. These two standards are slightly different, and the TCP/IP protocol handles this situatio

Chapter Review:"TCP/IP Detailed Volume 1: Agreement" 1th Chapter Overview-Reading Notes1. IntroductionAs can be seen from figure 1-4, in the TCP/IP protocol family, the link layer has three main purposes:(1) send and receive IP datagram for IP module;(2) send ARP request and receive ARP reply for ARP module.(3) send Rarp request and receive Rarp reply for Rarp.TCP/IP supports a number of different link layer protocols, depending on the hardware used by the network, such as Ethernet, Token Ring,
What is MVC? what is MVC?
I remember the first interview with phper (php is another web development language that can be quickly used for me). people asked me about MVC. I only know that m is model and v is view, c is the Controller. I know nothing about other things. as a result, I was asked questions !! I know how bad I am. So I decided not to give up on it! Find the following information:

The initial IGMP specification was defined in RFC 1112 in detail. We generally refer to this specification as "IGMP version 1", written by S. Deering of Stanford University in August 1989. Later, W. Fenner of Xerox PARC significantly updated the earliest IGMP version 1. The updated result is RFC 2236 file, that is, IGMP version 2. Two versions of IGMP can perform a few operations on each other. IGMP version 2 is nearing official

Later, the IEEE organization formulated the 802.3 standard, which stipulated the MAC Sub-layer of the Ethernet physical layer
