I believe many people have seen this request in the delivery of their resumes, many people will feel that we do not generally use this knowledge in the actual development, so we shrug off these things. But I think want to make a better APP, then the basic knowledge m

Currently, three most popular IP transmission technologies are available: IP over ATM, IP over SDH, and IP over WDM. All three IP transfer technologies will play their own roles in different periods of telecommunication network development and different parts of the network.

Only by the reputation of the IP past to do propaganda and powder, in the derivative process of the brutal operation of the savage operations has apparently put the IP economy into a bubble burst on the line.650) this.width=650; "src=" Http://s2.51cto.com/wyfs02/M00/84/79/wKioL1eRszSxddeLAAlaZcM5Ri4654.jpg "title=" 325235232363.jpg "alt=" Wkiol1erszsxddelaalazcm5ri4654.jpg "/>Wen/Zhang ShuleAccording to med

1. IntroductionIP is the most central protocol in the family of TCP/IP protocols. All TCP, UDP, ICMP, and IGMP data are transmitted in an IP datagram format. IP provides unreliable, non-connected datagram delivery services.(1) unreliableIt does not guarantee that IP datagrams will successfully reach their destination.

The pure version of IP data files can be used to optimize the query method, improve the format conversion efficiency, reduce the number of file reads, and quickly query IP addresses online. Greatly reduce the number of file reads, which should be beneficial to protecting the server's hard disk. Add a database browser to view the qq ip data files of the pure versi

Class d ip addresses (224.0.0.0 to 239.255.255.255) do not recognize a single interface on the Internet, but recognize an interface group, which is called multicast groups. Members of a single network use the IGMP protocol to communicate with each other. Multicast Routing Protocol for multicast routers, such as dvmrp (Distance Vector Multicast Routing Protocol, Distance Vector multicast routing selection protocol) transmits member information. In net/

This chapter describes the structure and basic IP processing processes of an IP group, including input, forwarding, and output. Shows the common organization form of the IP layer. In the previous article, we saw how the network interface put the IP Group to the IP Input Que

Gateway, we all know, from one room to another room, must go through a door. Similarly, sending a message from one network to another must pass through a "gateway", which is gateways. The gateway, as its name suggests, is a "gateway" to a network connected to another network. According to different classification criteria, there are many kinds of gateways. The gateway in the TCP/IP protocol is the most commonly used, where we speak of "gateways" that
