In order to understand HTTP, you must understand the TCP/IP protocol family.The network is usually used to operate on the basis of the TCP/IP protocol family. and HTTP belongs to a subset of him.1. TCP/IP protocol familyComputers and network devices need to communicate with each other, and both must be based on the sam

There are a number of ways to divide VLANs, usually based on VLANs.Methods for partitioning VLANs:1. VLAN-based2. Port-based3, based on network protocols, such as IP4. Policy-basedCommon is the above four kinds, of course there are other methods, but not uncommon.In fact, in the enterprise, I also base on the port to partition the VLAN, the benefits of partitioni

Java Processing IP tool classes, including the long type of IP to the general IP type, the xx.xx.xx.xx type to a long type, based on the mask bit to get the mask, based on the ip/mask to compute the

Content Summary: First compares the WLAN and the GPRS two kinds of technology characteristic, then proposed a mobile IP support WLAN/GPRS network seamless roaming fusion scheme. It uses WLAN network and GPRS network in the technical complementarity, can quickly provide users with the support of seamless roaming data services. This scheme is based on the following basic ideas: Try not to make any changes to

. An Internet architecture that can span multiple communication technologies is required. The IP architecture provides unprecedented connectivity for existing networks, applications, and services. Iii. IPv6 protocol for Internet of Things Why is IPv4 still so popular? Because of the cost and migration complexity! The current NAT technology breaks the rules for end-to-end communication in the IP architec

Editor's note: Sdn-ip is an application on Onos that allows software-defined networks to connect to external networks using standard Border Gateway Protocol (BGP). From a BGP perspective, the SDN network behaves as a single autonomous system (as), with the same behavior as any traditional as. The SDN-IP application based on as provides an integrated integration m

In the VC knowledge Base I learned a lot of knowledge, a very short time I mastered the VC, mainly in your station under a lot of source code back analysis, learning. Look at you. A person will be net send package to the source code of mass message, have seen the internet, such as mass message software to buy, so feel oneself to write a mass message small program. Characteristics: VC source code, based on the IP
