network protocols

Next-generation protocols related to IPv6 are in the TCP/IP protocol set. Protocols that are directly active and indirectly interoperable with IP addresses include various application layer protocols, connection protocols, and TCP and UDP. This chapter will discuss the impact of IPv6 on other layer

, 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-b

Internet Protocol IP and its supporting protocols @ (computer network) IP protocol is one of the two most important protocols in TCP/IP protocol cluster. The protocol is as follows: Address Resolution Protocol –arp Inverse address resolution –RARP Internet Control Message Protocol –ICMP Inter-Group Management Protocol –IGMP where ARP and RARP support IP protocol

I. Overview 1.1 Five-layer model The realization of the Internet, divided into several layers. Each layer has its own function, like a building, each layer is supported by the next layer. What the user touches is just the top layer, and there is no sense of the layer below. To understand the Internet, you must start from the bottom and understand the function of each layer. There are different models for layering, and some models are divided into seven layers and some four layers. I think it

The WAN protocol is relative to the LAN protocol, and the Internet can be identified as a wide area network. Then the relevant agreement is well understood. is inseparable from the OSI model. Here are a few typical protocols. To everyone as a reference. The WAN Protocol is a three-tier operation at the bottom of the OSI Reference Model, which defines communication on different WAN media. Mainly used for

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

IPsec is designed to solve some basic security problems of IPv4. To solve these problems, it implements four services: Data Transmission encryption, data integrity verification, data source authentication, and data status integrity. To implement these services, IPsec VPN introduces many protocols. In this article, you will learn how to implement the IPsec security protocol. Fifteen years ago, VPC was a new concept for most enterprises. However, today,

and provides services related to the existing GSM system. 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 inter

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

The routing protocol is used to exchange routing information between routers. With the continuous development of network technology, the more complex the network, and the emergence of new routing protocols. Through the routing protocol, the router can dynamically share information about the remote network. The routing

RFC2616).Before 1.1, there were two versions of "0.9 and 1.0", with HTTP 0.9 "not" widely used, and HTTP 1.0 being widely used.In addition, it is said that the IETF will release the HTTP 2.0 standard next year. I'll wait and see.2. The relationship between HTTP and TCPSimply put, the TCP protocol is the cornerstone of the HTTP protocol--http protocol needs to rely on the TCP protocol to transfer data.In the network layering model, TCP is called the T

multiple VPNs, because a sub-interface on the PE router belongs to more than one VPN, the VRF table corresponding to that sub-interface can only be assigned an RD so that multiple VPNs share an RD. The role of RT:RT is similar to the extended Community attribute in BGP for the distribution of routing information. It is divided into importrt and EXPORTRT, which are used for the import and export of routing information respectively. When you export a VPN route from the VRF table, you use EXPORTR

PPTP, L2TP, IPSec, SSLVPN, and other Protocols define and distinguish between VPN (Virtual Private Network). So far, it is no longer a pure encrypted access tunnel, it integrates multiple functions such as access control, transmission management, encryption, route selection, and availability management, and plays an important role in the global information security system. Also on the

to send IP groups that do not know where to send them. In this way, the router correctly forwards IP groups that know how to transfer them, and the IP groups that do not know are sent to the "Default Gateway" router. In this way, the IP Group will eventually be sent to the destination, IP groups that cannot be sent to the destination are discarded by the network. Currently, all TCP/IP networks are interconnected through routers. The Internet is an in

Before we talk about routing protocols, let's look at the structure of the routers:A router is a dedicated computer with multiple input ports and multiple output ports whose task is to forward groupings.The core of the routing part is the routing processor, which can construct a way out of the table according to the selected routing protocol, and Exchange routing information with regular or regular and neighboring routers to update and maintain its ow

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 net
