Ipx/spx Two network protocols are proposed by NetWare company primarily for LAN and network games where the IPX protocol has the full name of the routing function Internetwork Packet Exchange (Internetwork Packet Exchange), the IPX protocol is the most low-level network protocol with Novell NetWare, which is mainly used to control the addressing and routing of packets between LAN or LAN, only responsible for the transmission of packets in the LAN, do

Simple Network Management Protocol (Snmp:simple Network Management Protocol). The Simple Network Management Protocol is the SNMP protocol that we often refer to as a set of network management protocols defined by the Internet Engineering Task Force (ietf:internet Engineering task Force). The protocol is based on the Simple Gateway Monitoring Protocol (Sgmp:simple Gateway Monitor Protocol). With SNMP, a management workstation can remotely manage all ne

When using X and S locks to lock data objects, some rules need to be agreed, such as when to apply for an X lock or S lock, hold the lock time, and when to release. Called these rules for the blockade agreement (locking Protocol). The different rules governing the blockade form a variety of blockade agreements. Different blocking protocols provide certain guarantee for the correct dispatch of concurrent operation to different extent. 一、一级 Blockade Pr

The difference between get and post requests. 1, when the browser fallback and refresh, get harmless, but post will resubmit the data 2, get can be bookmarked, and post can not 3, get can be cached by the browser, and post can not 4. The encoding type of the GET request is application/x-www-form-urlencoded The encoding type of the POST request can be application/x-www-form-urlencoded and multipart/form-data 5, get parameters for the existence of browsing history, and post does not 6, get the url

transaction to be modified at all.Two-stage lock protocolThe database follows the "two-segment lock" protocol when scheduling concurrent transactions, which means that all transactions must lock and unlock data items in two stages Extended stage: Before you read or write any data item, apply and obtain a blockade of the data item. Shrink stage: In each transaction, all blocking requests must precede the unlock request. Mathematically, it can be proved that the scheduling with

be far greater than the number of humans. In this context, the Internet of things and technology have emerged. Although it is easy for people to connect to the Internet, access to the Internet is difficult for those tiny devices. In the current world of PC, information exchange is implemented via TCP and Application layer protocol HTTP. But for small devices, implementing the TCP and HTTP protocols is clearly an excessive requirement. The COAP protoc

Every time you write and design a network communication program, you always have to deal with the problem of customizing a set of application protocols (that is, communication protocols) and then writing corresponding methods to parse the protocols, and provides corresponding interfaces for upper-layer calls. It is easy to communicate text information, but it is

LAN protocol is the most important part of our LAN. With the coexistence of LAN and Internet. These protocols have also been affected by the deepening of Internet protocols. Computer network applications have been applied in almost all fields of human activity. The core of all network applications is network protocols. Network protocol is a supporting software an

More and more developers and designers want to open-source their products so that others can do more on the basis of their code. The open-source community is also full of vigor. Open-source software exists in all the application fields we can think of (open-source CMS such as WordPress and Drupal ). However, many people do not know about open-source licenses. This article describes several license protocols commonly used in the open-source field and t

through the local registry or group policy object (GPO. To do this, run Setup.exe from the SupportTools folder on Windows 2000 CD to install Netdiag.exe.2. Open the Command Prompt window and set the working folder to C: Program FilesSupport Tools.3. Run the following command to verify that an existing IPSec Policy is specified for the computer:Netdiag/test: ipsecIf no policy is specified, you will receive the following message:IP Security test ......: Passed IPSec policy service is active, but

1. Soap: Simple Object Access Protocol ^ {symbolic optimal assembly program }. 2.1.http-Get 2.2.http-post Soap Definition:Soap is a lightweight protocol used to exchange structured information in a distributed and distributed environment. Soap uses XML technology to define an extensible message processing framework. It provides a message structure that can be exchanged through multiple underlying protocols. The design idea of this framework is t

This article describes the basic working principles of routers in TCP/IP networks and introduces several functions of IP routers, the static and dynamic routing protocols, as well as the concepts of the internal gateway protocol and the external gateway protocol are given, at the same time, the most common RIP, OSPF, BGP and BGP-4 routing protocols are briefly introduced, and then the design objectives and

, intuitive, and efficient. Due to the large amount of information transmitted by digital videos and limited bandwidth, the compression and encoding of videos, selection of transmission channels and network protocols, and IP Multicast technology (IP Multicast) software Implementation Based on the Windows operating platform has become a key technology in network-based digital video transmission applications. Among them, the choice of transmission chann

languages. By using source code and documents, you can understand the architecture of the entire software and the implementation methods of a specific function. Object Code refers to the object code generated after the source code is compiled, similar to the "class library". It provides various interfaces for others to use. According to my understanding, it is something like common DLL, ActiveX, OCX controls. (I don't know if this is correct) The purpose of these two concepts is to make it clea

Many people may be familiar with the term Router Protocol, especially the rapid development of the network, the Internet Router Protocol is constantly improved, and many new features are also emerging. The wide application of information technology in various fields has promoted the rapid development of information exchange networks. Internet is the biggest beneficiary. The main node and device of the Internet network are routers. The router technology determines data forwarding through routing.

1 HTTPS Protocol OverviewHTTPS can be thought of as HTTP + TLS. The HTTP protocol is familiar, and most Web applications and websites are now transmitted using the HTTP protocol. TLS is the Transport Layer encryption protocol, its predecessor is the SSL protocol, was first released by Netscape Company in 1995, 1999 after IETF Discussion and specification, renamed TLS. If not specifically stated, SSL and TLS are all the same protocol. The location of H

For various reasons, many networks adopt multi-route protocols. This phenomenon is usually caused by merger and acquisition activities, or temporary occurrence during the migration. Many vro hardware manufacturers may use a variety of proprietary protocols to connect with standard protocols. Some routers will run more than one protocol and inevitably receive the

Core networks can connect users to various external networks and business platforms, such as circuit switched voice networks and packet switched voice networks (IP voice networks), data network, Internet, Intranet, e-commerce, SMS center, etc. 2. UMTS systems mainly include the following interface types: (1) B interface: MSC (vlr;(2) D Interface: MSC (HLR;(3) E interface: MSC (MSC;(4) GC interface: ggsn (HLR;(5) GJ interface: ggsn (exter

Many people may not have a special understanding of Static Routing and dynamic routing protocols. Here we mainly introduce the RIP and OSPF routing protocols. Static Routing is a fixed route table configured on the router. The static route does not change unless the network administrator intervene. Because Static Routing cannot reflect network changes, it is generally used in a network with a small network
