ports and protocols

This article compares the transmission performance of five communication protocols, including RMI, Hessian, Burlap, Httpinvoker, and web service, in different data structures and data volumes. RMI is a remote communication protocol provided by the java language. It is stable and efficient and is the basis of EJB. However, it can only be used for communication between JAVA programs. Hessian and Burlap are open source

IntroductionRMIIs the Java language itself provides a remote communication protocol, stable and efficient, is the basis of EJB. However, it can only be used for communicat

During the time when I started network debugging, I always wanted to figure out how LAN access to the Internet was. Now pay attention to your computer.

itself does not provide data encryption or identity authentication. Srtcp can be used for such purposes. SRTP srtcp Reference rfc3711 Secure real-time transmission protocol (secure real-time transport protocol or SRTP) is a protocol defined based on the real-time transport protocol or RTP, the aim is to provide encryption, message authentication, integrity assurance and replay protection for data in real-time transmission protocols in unicast and m

The reason why routers can run normally is the result of a lot of different protocols working together, why can the protocols coexist without affecting each other? This is what the following is about, the concepts of routing protocols running. VRF: One of the security initiatives of routing protocols is routing isolat

TCP dynamic port to 0. At startup, the instance checks the available ports in Windows and opens an endpoint for that port for incoming connections to the client. After the database engine has started successfully, you can view the port numbers that are currently in use in TCP dynamic ports.A dynamic port is typically provided by the SQL Server Browser service to the client to provide parsing services, otherwise the client must know beforehand which p

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 Transport Layer protocol, and HTTP is called t

layer:Routers, layer three switches Transport Layer:Four-layer switch, also has a router working on layer four T the CP (transmission Control Protocol) and UDP (User Datagram Protocol) protocols belong to the Transport layer protocol. TCP provides reliable data transmission in IP environment, and it provides services including data transfer, reliability, effective flow control, full duplex operation and multiplexing. Send through connection-oriented,

First, the switch types are divided into low-end (SOHO-level) and high-end (enterprise-level ). An important difference between the two is the low-end switch. Each physical port is a logical port, while the high-end switch binds multiple physical ports into one logical port for configuration. In a cisco Network, the switch is eventually stable in the LAN First, the switch types are divided into low-end (SOHO-level) and high-end (enterprise-level ). An

The steps for configuring Static Routing Protocols are complex. Each step is very important. You need to pay special attention to the configuration process. We also need to sum up experience to avoid unexpected errors. I. Two Static Routing Protocols 1. The S0 port address of R1 is 192.168.1.1, And the E0 port address is 10.10.254. The S0 port address of R2 is 192.168.1.2, And the E0 port address is 255.255

Today, we will learn about Internet protocols in terms of addressing, segmentation, and gateway. The addressing method is also the address method we currently use in the IPv4 protocol. With the continuous development of the network, we will replace the current IPv4 with the IPv6 protocol, and the address protocols of the two are also different. In the subsequent articles, we will also compare the two. Addre

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 wide area network communication
