tcp ip book

After reading some chapters and book directories in the book "TCP/IP protocol family", I feel that this book is rich in content and involves all aspects of network protocols. They all said that this book is illustrated in images a

Introduction to tcp protocol (TCP/IP) and TCP/IP Role of the transport layer: the IP layer provides point-to-point connections, and the transport layer provides end-to-end connections. Transport Layer Protocol 1.

1th Chapter the concept of TCP/IP TCP/IP refers to the set of network protocols used for the Internet and many other networks. TCP/IP Features: Ø logical addressing-the physical address (MAC address) is a unique and permanent ad

the Ethernet receive this frame and check the target address. If the target address and network adapter address are the same, the adapter software processes the received frame and transmits the data to the higher layer in the protocol stack. Chapter 2 Internet Layer Addressing and sending-- In a selected route network, the TCP/IP software uses the following policy to send data on the network: 1. If the

I. TCP/IP background and introductionIn the 70 's, with the development of computer technology, computers users realized that it was necessary to connect computers from all over the world to play a more important role in computer. But the simple connection is not enough, because the computer can not communicate. Therefore, the design of a common "language" to communicate is necessary to be less, then the

(segment). Session Layer: Manages the session process between hosts, including management during session creation, termination, and sessions. The presentation layer (presentation Layer): The presentation layer transforms the data transmitted by the network, so that the information transmitted between multiple hosts can understand each other, including data compression, encryption, format conversion and so on. Application layer (Application Layer): The application layer communicates with the app

I have written this article about the management of SCO TCP/IP. I hope it will be helpful to you, just like what was written at the beginning of this topic, this is the basis for hackers, and we still need to discuss it in the direction of network management! Haha!1 TCP/IP startupTCP/

IP: Internet Protocol Unreliable: IP datagram cannot be successfully delivered to the destination, and only the best transmission service is provided. No connection: the IP address does not maintain any status information about subsequent datagram. The processing of each datagram is independent of each other. IP Heade

Different TCP/IP layers provide different security. For example, a virtual private network is provided at the network layer and a secure connection service is provided at the transmission layer. The following describes the security of TCP/IP at different levels and the methods to improve the security of each layer.I. S

What is the TCP.IP protocol? Generally speaking, TCP/IP protocol is the Technology foundation of Internet based on TCP/IP protocol (Transmission Protocol/Inter-network protocol). Full name Transmission Control protocol/internet Protocol. The Protocol of Transmission Control Protocol/Internet, also known as network Comm

. (3) If the destination IP address is "non-local (non-local)", MSS usually has a default value of 536.Description: The method of distinguishing whether the address is local or non-local is local if the network number and subnet number of the destination IP address are the same as the native, if the destination IP address has the same network number as the native

The TCP/IP network communication software package uses remote access commands. These commands were first developed for Arpanet by UC Berkely. It allows you to remotely register to another system and copy files from one system to another. You can obtain information about a system, such as who is currently registering for use. When calling a system address, these remote commands use the domain name or

Introduction: Before 1990, the hierarchical model dominated by data communication and networking literature was the Open Systems Interconnection (open system Interconnection,osi) model, and now the TCP/IP protocol family became the dominant commercial architecture. An OSI seven-layer model 1.1 Physical Layer The mechanical and electrical specifications that relate to the interface and the transmission media

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. IP (Internet Interconnection Protocol)IP is the transmission mechanism, unreliable, "best effort" of TCP/

address select the next hop IP address (also be a routing device or virtual routing device or destination address), through the ARP protocol to get to the next hop MAC address, modify the packet, The destination MAC address is set to this address, which is thrown to the link layer and sent out by the link layer. Router Isolated broadcast domain The transport layer, including the TCP protocol, is the UDP

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

However, if the socket is disconnected, then sending data and receiving data will definitely cause problems. How can I tell if a socket is available? How
