Selection of transmission layer protocols for digital video Networks

transmission protocol selection is concentrated on the transport layer We know that the OSI (Open System Interconnection) network reference model developed by ISO divides the network into seven layers, which are listed in the following order: physical Layer, data link layer, network layer, transmission

A detailed description of routing protocols in computer networks

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 neig

Simple expression of application layer protocols

We all know that networks are divided into different layers. In the application layer, some application layer protocols protect our e-commerce systems. In this regard, let's talk about the relevant content. It is an important issu

Security issues of application layer protocols

Some of our commonly used network applications, such as e-commerce, are implemented at the network application layer. So how can we ensure security in the application layer protocol? In this regard, we will mainly discuss the SET protocol. First, let's take a look at the security protocol environment on the Internet. I

and network address translation NATVPN (Virtual private network) uses the public Internet as the communication carrier between the private networks of the agency. VPN internal use of the private address of the Internet. A VPN must have at least one router with a legitimate global IP address in order to communicate with another VPN on the system over the Internet. All data transmitted over the Internet must be encrypted.Using Network address translati

1, Network layer Responsibilities:Responsible for forwarding packets between different networks (based on IP address), not responsible for retransmission, not responsible for the order.Note: During the two host communication process, each packet selects a routing path individually.2, the router can see the IP address, so work in 3 layers. The following application

program (customer service sends the number of operations, operands, operators, and the server receives the data to end to the client): The customer service side is connected to the server side and passes the operands in 1-byte integers as a number. Each operand that the customer service side passes to the server is a 4-byte integer data. After each operand is passed, the operator is then passed, and the operator occupies 1 bytes. The server returns the result of the operati

process of obtaining the IP address corresponding to the host name through the host name is called domain name resolution (or host name resolution ). The DNS protocol runs on the UDP protocol and uses the port number 53. HTTP: This is the most widely used protocol. It is often referred to as "Hypertext Transfer Protocol ". When browsing the Web page online, you have to open port 80 on the computer that provides web page resources to provide services

mask, so that it is convenient to obtain the IP address of the network address, and do not need to find the routing table. A subnet mask is an important property of a network or a subnet. In each item of the router's routing table, in addition to giving the destination network address, you must also give the subnet mask for the network. If a router is connected to two subnets, two IP addresses and subnet masks are given 、、。 Forwarding by using subnet time group

. Processes of different systems communicate with each other by exchanging packets across computer networks. It can be divided into client processes and server processes. In a given communication session between processes, the process initiating communication is a client process, and the process waiting for connection is a server process. A process sends and receives packets over the network through a softw
