, FDDI Data link layer, ATM (asynchronous Transfer mode, asynchronous Transfer Mode), IEEE 802.5 (Token Ring), frame Relay (Frame relay) Network Layer : Responsible for routing data packets between subnets. In addition, the network layer can also realize congestion control, Internet interconnection and other functions. Packet, pack. Typical protocol representative: IP, ICMP, IGMP, IPX, BGP, OSPF, RIP, IGRP, EIGRP, ARP, RARP, x. Transport Layer (Tr

Solutions When the client starts a TCP/IP socket connection to the server, the client usually connects to a specific port on the server and requests the server to respond through a temporary (or temporary) TCP o

You may have heard of the TCP/IP protocol. Do you know what TCP is and what Ip is? In this chapter, we will learn about the most widely used protocol on the network. 7.1 network transmission layeringIf you have passed the computer grade examination, you should have understood the concept of network transmission layeri

The common understanding of TCP/IP network protocols was developed some time ago. network programming was involved and the development process was smooth. However, after the task was completed, I always felt a bit confused. The main reason is that you are not familiar with network protocols and are not clear about some concepts. Later, I spent some time learning about these network protocols. Now I have a p

From: http://blog.jobbole.com/74795/ Some time ago I made a development, involving network programming, and the development process was quite smooth, but I always felt a bit confused after the task was completed. The main reason is that you are not familiar with network protocols and are not clear about some concepts. Later, I spent some time learning about these network protocols. Now I have a preliminary understanding of the TCP/

Apply button on the right, or enter to make the filter effective. The contents of the input box are also the contents of the current filter (the contents of the current filter are reflected in the input box) 4. Package List All packets that have been captured are displayed in the package list. Here you can see the MAC/IP address of the sending or receiving party, the TCP/UDP port

Source: TaubonrenLinks: http://blog.jobbole.com/99694/Since it is a network transmission, involving the interaction between several systems, the first thing to consider is how to accurately locate one or several hosts on the network, and how to carry out reliable and efficient data transmission. This will use the TCP/IP protocol.1.1 TCP/

header and packet data lengthIdentifier: A uniquely identified number used to identify the order of a packet or a fragmented packetFlags: Used to mark whether a packet is a shard, and the values in that domain are used to reorganize the packets in the correct orderSurvival time: Defines the generation period of the packet, minus 1 per routerProtocol: A type used to identify upper-middle-order protocol packets in a packet sequence, such as ICMP,TCP,UD

the datagram data zone. ICMP is 1, TCP is 6, and UDP is 17. Protocol Number: rfc790. Header checksum (16 bits) is only used for IP header checksum. Source IP address and destination IP address. Fill field is used to ensure that the option field is filled with at least 32 bits to ensure that the

TPC/IP Protocol is a Transport layer protocol, which mainly solves how data is transmitted in the network, and HTTP is the application layer protocol, which mainly solves how to wrap the data. regarding the relationship between TCP/IP and HTTP protocol, the network has a relatively easy to understand: "When we transmit data, we can only use the (Transport Layer)

TCP/IP routing protocol fault handlingFirst, the default gatewayWhen the destination address of the package is not in the router's routing table, such as when the router is configured with a default gateway, it is forwarded to the default gateway or discarded.show IP route; View the default gateway for Cisco routersSecond, static and dynamic routingThird, pr

the difference between IP fragmentation and TCP segmentation 1, MTU (Maximum transmission UNIT,MTU), Maximum transmission unit(1) Ethernet and 802.3 have a limit on the length of the data frame, with a maximum value of 1500 and 1492 bytes respectively. This feature of the link layer is called the MTU. Most of the different types of networks have an upper limit. If the
