tcp ip ports and protocols

, so I thought about how to solve the problem of insufficient tcp client ports. Because the default port 65535 is configured and the maximum number of ports is less than 60000, how can it reach a million? After reading UNP, I have mentioned four scenarios of the SO_REUSEADDR application: SO_REUSEADDR allows a single process to bind the same port to multiple socke

TCP/IP OSI Application Layer-Application layer, presentation layer, Session layer Transport Layer-Transport layer Network Layer--Network layer Network interface Layer--physical layer, Data link layer The current TCP/IP protocol still looks at the network interface layer as the physical layer and the data link layer

OSI Reference ModelOSI RM: Open Systems Interconnect Reference Model (open Systeminterconnection Reference Model)The OSI Reference model has the following advantages: Simplifies the related network operation; Provide compatibility and standard interface between devices; promote standardization work; The structure can be separated; Easy to implement and maintain. Since the 1960s, the computer network has been growing rapidly. In order to do

Completely solve the problem of insufficient TCP client ports [problem] When making large concurrent performance calls at www.2cto.com, we often encounter a problem: the client port is exhausted. [Cause] After analysis, the main cause is that there will be a timewait time after the connection is disconnected, and the socket will be retained and occupied. [Solution] solution 1 is always written on timewait a

Implement TCP/IP programming under DOS real model (lower) Http://blog.csdn.net/dos5gw/archive/2010/03/29/5429582.aspx There may be very few people using DOS, and fewer people are working on DOS. There are many reasons. But in terms of industrial control, there are still a lot of DOS users, especially dos622 and dos71 are still running smoothly on many industrial computer, POS machines, and supermarket ca

client is the party that initiates the request, it must know the IP address of the server and the port number of the service process, so some common network protocols have default server ports. In the TCP/IP protocol family, the port number is an integer between 0~65535. IC

the IP port that SQL Server listens on or create a SQL Server alias that specifies an IP port. About the Client Network tool is detailed below.Third, TCP/IP static port, dynamic port, SQL Server Browser and UDP 1434 port conceptFirst, discuss port 1434. What is the 1434 port for?We all know that SQL Server supports mu

address of 128 bits, and the number of IP addresses can be as high as 296 times times. This will solve the problem of insufficient Ipv4 address resources, and IP address will be the domain network structure corresponding to improve the efficiency of the route.1.2.2 RoutingA router is a packet-forwarding device that works on the third layer of the OSI Reference Model-the network layer. Routers enable networ

RARP (Inverse Address Resolution Protocol)Rarp is to map the physical address to a logical address, the RARP request is sent by broadcast, the answer is sent by a single advertisement.Three.
