WCF -- Address, wcf endpoint address
The endpoint is the core image of WCF because it carries all the communication functions. The service is released through the corresponding endpoint. The client calls the server through a matching endpoint. The endpoint consists of three elements: Address, binding, and contract, which are also called three elements of ABC. URL: the WEB is uniquely identified by a URL, and the service is published through an endpoint. Therefore, most scenarios of a service refer to an endpoint of a service. The core of the endpoint address is the URL, which can be used as a unique identifier. It also provides routing and addressing functions. a url not only represents the location of the service, but also the target address of the message routing. HTTPS/HTTP: HTTPS: Secure Hypertext Transfer Protocol, using ssl http. SSL is an encrypted protocol. Many security websites Use HTTPS. WCF ensures service security through HTTPS. HTTP features: Here is a detailed description. If you are interested, please take a look.

In the simplified computer network OSI model, it completes the functions specified by the layer-4 transmission layer. User Datagram Protocol (UDP) is another important transmission protocol in the same layer [1. In Internet protocol suite, the TCP layer is located above the IP layer and under the application layer. Different Host application layers often require reliable connections like pipelines, but the IP layer does not provide such a stream mechanism, but provides unreliable packet switching. The Application Layer sends an eight-byte data stream for inter-network transmission to the TCP layer, TCP then partitions the data stream into a packet segment of the appropriate length (usually restricted by the maximum transmission unit ([1] MTU) of the data link layer of the network connected to the computer ). Then, TCP sends the result packet to the IP layer, which transmits the packet to the TCP layer of the receiver entity [1] over the network. To ensure that no packet loss occurs, TCP sends an serial number to each packet, and the serial number also ensures the packets sent to the receiving end in sequence. Then, the receiving end entity sends back a corresponding ACK to the packet that has been successfully received. If the sending end entity does not receive confirmation within the reasonable round-trip delay (RTT, the corresponding data packet is assumed to have been lost and will be re-transmitted. TCP uses a checksum function to check whether there is any data error. The Checksum is calculated during sending and receiving.
