These days because of the laboratory off the net, so has been unable to send essays, but good habits still have to insist.Today, let's talk about an important layer-the transport layer. The Protocol of Transport layer is mainly divided into TCP protocol and UDP protocol. The former is referred to as Transmission Control Protocol, which is packet transport. Today,

What do I need to be aware of by compressing or json formatting? 5. References 1. How do I transfer data when I encounter the need to transfer large amounts of data?2. What are some common ways to compress data?Question 1 Answer: transfer data by compressionQuestion 2 Answer:(1) The compression method of the WCF comes with

has been on the network layer and the transmission layer of computer networks are more ambiguous, read the Shehiren of the textbook, is this explanation: Transport Layer: Services for communication between processes in two hosts Network layer: Responsible for providing communication services for different hosts on the packet switching network Understanding or more abstract, by chance on the blog found a more vivid explanation: Original address In

"Title description" The logistics company is going to ship a batch of cargo from Wharf A to Pier B. Due to the large volume of goods, it takes n days to complete the shipment. In the course of cargo transport, sev

I. Role of the transport layer 1. Track sessions Because each host may have multiple processes for communication, the transport layer needs to send each data segment to the corresponding process. This can also be understood by adding the source and target process numbers (actually the port number) to the transport layer header ). 2. segment data and manage each s

Today, with the release of Xcode 7, the app compiles a lot of warnings, and when the app runs, the following tips appear ...The resource could not being loaded because the app transport security policy requires the use of a secure connectionThe resource cannot be loaded because the application transmits a security policy that requires the use of a secure connectionIOS9 introduces a new feature App Transport

The Transport Layer belongs to the upper layer. Above it is the application layer, and below it is the network layer! In end-to-end transmission, the transmission layer must be used. The scope of the transport layer is the end device. The main functions of the transport layer are as follows: 1) reusing data packets from the application layer and then sending th

In the protocol stack, the transport layer is located on the network layer. The Transport Layer Protocol provides logical communication for processes running on different hosts, while the network layer protocol provides logical communication for different hosts. The difference is subtle, but important. Let's use a family as an analogy to illustrate this difference. Suppose there are two houses, one on the

TCP/IP Note 3. Transport Layer (3) -- TCP timeout retransmission algorithm TCP sets a timer for each packet segment sent by TCP. As long as the retransmission time set by the timer is reached but no confirmation has been received, it is necessary to re-transmit this packet segment 1. average round-trip latency RTT round-trip latency: the time when a packet segment is sent and the time when the corresponding validation packet segment is received.
