Learn about network service protocol, we have the largest and most updated network service protocol information on alibabacloud.com
File Transfer The examples used in the previous two articles are transmission strings. Sometimes we may want to transfer files between the server and the client. . How can we accomplish this? There may be two methods: Similar to the FTP protocol, the server opens two ports and continuously listens to these two ports: one for receiving strings, similar to the FTP control port, which receives various commands (receiving or sending files ); one is use
Open Shortest Path First (Open Shortest Path First) is a very active link status Internal Gateway Protocol (IGP). When people find RIP (route information Protocol) it cannot be applied to larger networks, and OSPF is adopted when the convergence speed is too slow. This article will give a general introduction to the OSPF protocol, and the next lecture on basic
Uploading large files with the HTTP protocol may be a difficult problem to run. Mainly because of its discontinuity, making uploading files feel very "dangerous". In particular, a large file (hundreds of MB or even on the G file), the mind always feel not practical, inadvertently will appear problems, and a problem can not continue to upload, it is very depressing. Later on some sites to find some of the upload file components, but are to use some CO
OSI (open System interconnect) is an open communication system Interconnect Reference Model, which is a well-defined protocol specification. The OSI model has 7 layers of structure, each of which can have several sub-tiers. The OSI layer 7 from top to bottom is 7 Application layer 6 represents Layer 5 session Layer 4 Transport Layer 3 Network Layer 2 data Link Layer 1 physical layer, where the upper layer (

The UCMQ is a lightweight HTTP protocol-level Message Queuing service component that was originally prototyped from the Httpsqsof the "feast".Basic Features: Supports standard HTTP protocol (Get/post method), supports long connection (keep-alive); Request response is very fast, into the queue, out of queue speed of more than 10,000 times/second;
Change of location service in IOS8 (Cllocationmanager protocol method does not respond, unable to return the GPS method, does not appear to get permission prompt)Recently, when writing a lbs project, because of the adaptation of IOS8, the project was migrated to the Xcode6.0.1, there was a problem that could not get the location service permissions properly. Self
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
diagnostic, the system gives the hint that Windows cannot automatically bind the IP protocol stack to a network adapter. According to this keyword, found the method. The situation I encountered was slightly different. Open Control Panel >> Network and Internet >> Network Connections, right click on the
After the network driver receives the packet, the skb-> protocol field is initialized. The receiving function netif_receive_skb at the link layer determines based on this field and sends the message to the protocol module for further processing. Ethernet device callEth_type_trans) To assign values to skb-> protocol

Reprinted from: http://blog.sina.com.cn/s/blog_48d4cf2d0101859x.html For the first network programming developers, the communication protocol design is generally confused. This aspect is also less relevant in general web-programming books. Guess it's too easy. This piece is really not difficult, but if you don't know it, it's easy to get out of a basket or detour. Let's talk about

Bkjia.com exclusive translation] In general, Web services have always been a niche tool that is difficult to accurately define, interpret, and use. This is actually a misunderstanding. Click here for details. I also want to eliminate this misunderstanding through some technical and code examples. In this article, we will specifically discuss SOAP. Of course, JSON and REST are also popular important standards, but here we will focus on SOAP. Simple Object Access
