Tcp-ip detailed volume 3:TCP transaction protocol, HTTP, NNTP, and UNIX domain protocol "PDF" Download Link:https://u253469.pipipan.com/fs/253469-230062539Content IntroductionThe TCP. IP Detail (Volume 3): CP Transaction Protocol. The HP.P and UIX domain protocols are the continuation of the TCP/IP detailed series. The main contents include: TCP transaction

Note: The content of this article comes from the Netizen God, as the study note record in this. If there is a similar, please understand;The TCP/IP protocol stack is divided into four layers: application layer, Transport layer, network, data link layer, each layer has corresponding protocol;The so-called protocol: is a format for both parties to transmit data. Th

first, the protocol formatThe format of the ARP protocol is as follows: two chunks to explain: 1, the red box up is: Ethernet header, a total of 14 bytes. This is part of the packet that you send whatever Ethernet protocol you want, and it is necessary. Description of each field: Field The number of bytes occupied Description

As the basis of web services, HTTP protocol should be taken seriously, but colleagues around the world can clearly understand the rare issue of HTTP protocol. Since it is the foundation, we should be able to master it earlier, so we have been using it for nearly half a year (January 1, June 2016) As the basis of web services, HTTP protocol should be taken serious

Bacnet-building Automation and control network for short, for the building automation network and communication protocols developed. An open building automation communication standard developed by the American Association of HVAC Engineers. December 1995 was approved as the United States national standards, and formally named Ansi/ashrae 135-1995 Standard. January 2003 becomes the official standard iso16484-5 of the ISO. BACnet with its openness, ease of expansion, flexibility of the characteris

tolerated, so we adopt the UDP transport protocol. But the UDP protocol itself is non-connected and does not provide quality assurance. The high-level protocol rtp/rtcp based on UDP can provide traffic control and congestion control services together. The graph gives a RTP/UDP/IP-based H. 264 frame for video transmission.H. 264 RTP encapsulation strategy for vid

Routing protocol is divided into static routing protocol and dynamic routing protocol. There are many kinds of dynamic routing protocols, such as RIP, OSPF, EIGRP, and so on.1. RIP (Routing Information Protocol) is the first open standard used between router manufacturers. RIP has two versions: RIPv1 and RIPV2, which a

Preliminary Study on WCF-19: WCF Message Protocol, Preliminary Study on wcf-19 ProtocolWCFMessage Protocol Overview When a WCF application is generated, developers usually pay close attention to the data structure and serialization issues, rather than the message structure carrying data. For these applications, it is easy to create data protocols for parameters or return values. However, it is equally im

HTTP protocol learning and http protocol Learning 1. HTTP Overview HTTP is actually a set of language communication rules! Http uses a reliable data transmission protocol. Therefore, even if the data comes from the other end of the earth, it can ensure that the data is not damaged or messy during transmission. B/SStructure In the browser, the user requests the sp

RIP: A distance vector protocol, the distance is distance, the number of hops to represent, vector is vectors, interface to represent. Based on the Bellham-ford (distance vector) algorithm, belongs to the IGP (Internal Gateway Protocol) class. RIP is divided into the class routing protocol (RIPV1) and the No-class routing P
