| - | ===== Integration based on TCP/IP Sockets ===== | ||
| - | |||
| - | The client sends requests to the server over a TCP socket connection, and the server responds to these requests with appropriate data. | ||
| - | |||
| - | Here are the basic steps involved in integrating software systems or components using TCP socket communication: | ||
| - | |||
| - | - Choose a protocol: TCP/IP is a common protocol for socket communication, but other protocols like UDP can also be used depending on the requirements. | ||
| - | - Determine the message format: Decide on the format of the messages that will be exchanged between the client and server. This could be a simple text-based format or a more complex binary format. | ||
| - | - Define the communication interface: Define the functions or APIs that will be used for communication between the client and server. | ||
| - | - Set up the server: Write the code for the server that listens for incoming client connections and handles incoming requests. | ||
| - | - Set up the client: Write the code for the client that connects to the server and sends requests. | ||
| - | - Handle errors: Implement error handling mechanisms to ensure that communication errors are handled gracefully and do not cause the system to crash or become unstable. | ||
| - | - Test and iterate: Test the system thoroughly and make any necessary changes or improvements to ensure that it is functioning correctly. | ||
| - | |||
| - | Summary: | ||
| - | |||
| - | * Socket ::= IP address + (TCP/UPD) port number | ||
| - | * TCP Sockets provides 'real-time' data transfer | ||
| - | * binary data transfer but can be normal text or XML as well | ||
| - | * no direct method sharing (can be done by hand) | ||
| - | * TCP and UDP connections are possible. UDP is 3 times quicker but one-way communication | ||
| - | * Persistent or On-Demand communication channel | ||
| - | * because of connection time-loss usually persistent channels are better, but periodically 'ping' messages should be sent. (in order to avoid connection closing). In case of any problems reconnection is possible | ||
| - | * in case of UDP channels an extra TCP channel is available for synchronizing - in online games | ||
| - | * Results in the fastest possible transmission. | ||
| - | * Where the number of transactions per second up to ~ 20 transactions, there should have been applied. (50ms / sec transfer) | ||
