packet is the second data segment generated, the multipart mark is equal to the value in the original datagram, and the segment offset is equal to the value in the original datagram plus NFB. The above process can be expanded from 2 to N. For segment reorganization, the following four domains must have the same values: Tag, source address, target address, and protocol. Recombine different datagram data into a new segment based on its own offset. the offset of the first segment is 0, and the mul

Two types of transport protocols: TCP,UDPTCPTCP is the short name of Transfer Control Protocol , which is a connection-oriented protocol that guarantees reliable transmission .In the TCP/IP protocol,IP layer is mainly responsible for the location of the network host, the routing of data transmission, by the IP address can uniquely determine a host on the Internet　　 . 　　The TCP layer provides an application-

[Boiled ASP. NET Web API2 methodology] (3-2) Direct routing/attribute routing, api23-2 Problem How can I define a route in a way closer to a resource (Controller or Action. Solution You can use Attribute routing to directly declare a route at the resource level. You only need to simply use RouteAttribute on the Action, and then pass a relevant

When we analyzed the AdHoc wireless network, we found that its routing protocol is very important. If its routing is under attack, the entire network would not work normally. Therefore, it is necessary to analyze and discuss its routing protocol in depth. AdHoc wireless network routing protocol design requirements A ke

1. TCP/IP protocol stackLayer-4 ModelThe TCP/IP protocol follows a four-layer model concept: application layer, transport layer, Interconnection layer, and network interface layer.Network Interface LayerThe basic layer of the model is the network interface layer. Sends and receives data frames. frames are independent network information transmission units. The Network Interface Layer places frames on the Internet or retrieves frames from the Internet.Interconnection layerThe Interconnection prot

server receives the fin, it sends back an ACK, and confirms that the sequence number is the received sequence number plus 1. As with Syn, a fin will occupy a sequence number. The server shuts down the client connection and sends a fin to the client. The client sends back ACK message acknowledgement and sets the confirmation sequence to receive the serial number plus 1UDP protocol: The Protocol is also a transport layer protocol, but also for the transmission of data, is an unreliable transport

It was previously mistaken to assume that direct-link routing is preferred if the metric is larger than the host route metric. However, it is forgotten that routing matching should be prioritized with a detail route, so the host route is selected first, although the hosting route metric value is smaller than the direct-attached route because the host route is the most verbose (no more detailed than it is).

The Wireless Mesh Network is a multi-point-to-Multi-Point Wireless Network developed from the Ad Hoc network. Currently, the routing protocols of the wireless mesh network refer to Ad Hocl to a large extent ~ The typical routing protocol directly applies the Ad Hoc routing protocol to the wireless mesh network environm

The data Link layer provides many functions, so it is divided into two sub-layers: MACMedia Access Control and Media Access Control) layer and LLCLogical Link Control and logical Link Control layer. The common L2 standard for LAN and man is IEEE 802 protocol. In the wide area network, HDLCHigh-level Data Link Control, advanced Link Control), PPPPoint-to-Point Protocol, Point-to-Point Protocol), Frame Relay, and other protocols are widely used.

It has been nearly a year since learning CCIE, although this year has left a lot of knowledge about routing switching technology, but with this year's learning of Linux and Python and school-related courses, the understanding of TCP/IP is becoming clearer, At least you can slowly form your own ideas, so I would like to take this opportunity to tidy up the past thoughts, writing "in-depth understanding of the Common Network Protocol" blog topic.Bloggin

VroTwo main functions are available: Data tunnel and control. The data channel functions include forwarding decision, backplane forwarding, and output link scheduling, which are generally completed by specific hardware. The control functions are generally implemented by software, it includes information exchange with neighboring routers, system configuration, and system management.

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

-scale network environments. The RIP protocol is used to transmit route information in an AS autonomous system. Route information is updated every 30 seconds. The RIP Protocol provides hop count to measure the route distance, the hop count is the number of routers required for a packet to reach the target. The maximum number of hops supported by RIP is 15. Application: in Windows, we can enable the "RIP listener" function to listen to RIP messages, so that the computer can understand other route
