the address type to be converted, and 0x0800 is the IP address, the length of the following two addresses is 6 and 4 (bytes) for the ethernet address and IP address respectively. The op field is 1, indicating the ARP request, and the OP field is 2, indicating the ARP response. The process of the Address Resolution Protocol is as follows: Iv. RARP (Reverse Address Resolution Protocol) The opposite of ARP is mainly used to obtain the IP address of a diskless workstation, as shown in. 5. ICMP

artificially banned, so there are other mechanisms that can still pass SessionID back to the server when the cookie is banned. This technique is called URL rewriting, that is, the SessionID directly appended to the URL path, there are two additional ways, one is as the URL path of additional information, the representation of http://www.wantsoft.com/index.asp; Jsessionid= byok3vjfd75apnrf7c2hmdnv6qzcebzwowibyenlerjq99zwpbng!-145788764.The other is appended to the URL as a query string, in the f

Common ping command protocols in the Network Network Protocol Network Firewall Router ICMP is the abbreviation of "Internet Control Message Ptotocol" (Internet Control Message Protocol. It is a sub-Protocol of the TCP/IP protocol family. It is used to transmit control messages between IP hosts and routers. A message c

ICMP is the so-called Internet Control Messaging Protocol (PROTOCOL), which is commonly used to transmit error messages and other information that should be noted in the network. ICMP is generally considered to be the same level as the IP protocol, IMCP packets are usually used by IP layer or higher level protocol (such as TCP or UDP), ICMP for the internet and other ip-based network based on the normal ope

This article describes the first example: five simple TCP Network service protocols, including Echo (RFC 862), Discard (RFC 863), Chargen (RFC 864), Daytime (RFC 867), Time (RFC 868), and time The client of the Protocol. The functions of each agreement are as follows: * Discard-discard all data received; * Daytime-service-side accept connection, send the current time as a string, and then actively disconn

files and their protocols. Note: Here said that send, receive file is standing in the position of the client said, when the client sent the file, for the server to collect, is to receive files. 1.2 Receiving files The receiving file is actually exactly the same as sending the file, except that the client writes data to the network stream or the server writes the data to the

As long as your network architecture management and preparation are in place, VoIP will be excellent on the wide area network. Enterprises should know that the performance of the VoIP system is no different from that of the traditional TDMPBX.

(Fan Zhongli Nanjing University of Posts and Telecommunications, Nanjing 210003) A standardized optical control plane is introduced in this paper. The optical control plane is decomposed into a few basic processes such as Neighbor Discovery, service discovery, Connection control and Topology/resource discovery. Different network organization and segmentation result in several different automatic configuration models: Soft persistent link model, user

Install NetBEUI protocol in WinXP Right, you are not wrong, is to install the NetBEUI protocol in the WinXP. Microsoft only supports the TCP/IP protocol and the NWLink Ipx/spx/netbios compatibility protocol in WinXP, officially announcing that it no longer supports the NetBEUI protocol

Notes on data communication and network-wide area network SONET/SDHThe high bandwidth of optical fiber is suitable for carrying large amounts of data at the same time in today's high data rates and low rates. For this reason, optical fiber and the need for data rate or high-bandwidth transmission technology to develop together, and then there is a need for standa

With the development of network technology and the popularization of information application, Ethernet switch has been used more and more widely. More importantly, it began to penetrate from the simple LAN application to the metropolitan area Network, thus attracting more operators ' eyes.
