[ASIO] Async TCP/UDP server design help
I'm having hard time understanding the boost asio design and how i can use it to tackle my problem. My problem: Designing a tcp/udp server that is time efficient. 1. User sends packet through tcp 2. Server receives packet and processes it to build a large tree (n > 20000) 3. Server then parses the new tree and sends a summary packet through udp to another client Conditions/Limitations: - Has to be time efficient, receiving, processing and sending has to be done as fast as possible. - Processing the packet is heavy and can cause delays if its done in the same thread - Parsing the tree is also a little heavy when sending it through udp, can cause delays too Design 1 (2 threads): Thread 1: ASIO TCP and UDP. TCP receives packets and adds it to a circular buffer. While at the same time, processes the shared tree and sends packet through udp. Thread 2: Server grabs packet from circular buffer and processes it Some problems here: - I dont understand the async part here. What happens when tcp receives a packet, if the current thread is continuously parsing the tree and sending packets through udp. Do i need to separate the udp part to another thread? - I have 3 parts of the program that i need to run concurrently, well its really 2 parts and receiving packets through tcp. Any help is appreciated. Thanks,

I would use a modular approach using an acceptor, a shared job queue, and multiple worker threads (at least 2 workers; depends on the job characteristics, duration etc.). Of course a synchronisation/locking is needed for shared resource access/usage, see for example https://en.wikipedia.org/wiki/Producer–consumer_problem -- U.Mutlu DACOS Notdienstanlagen GmbH, Germany, www.dacos.de
Hi Terry,
I might have solved your problem for you already.
Try taking a look at: http://github.com/TheLastCylon/kisscpp
Documentations, such as it is, is available here:
http://thelastcylon.github.io/kisscpp/index.html
Currently, there is no UDP support, but I'm sure it won't take much to get
that in.
Feel free to ask questions, if you want.
