multiple m3au link example

[parsibox]

hi can we connect to multiple m3ua link? can you add an example for it?

[wmnsk]

Basically you can just repeat these lines in the example. https://github.com/wmnsk/go-sccp/blob/1c9ff26fff8eae91573d45a0a7a0817544f3dc4d/examples/client/simple-client.go#L46-L73

and after that load balancer also work? only this?

[wmnsk]

Do you mean traffic mode type = load share? Such behavior is not built in, and users need to handle each m3ua.Conn as they want.

[parsibox]

Yes, that's exactly what I meant ok if we have 2 m3ua link can we detect which of them dead or have error? i think we only detect this when we call m3conn.Write and get error , is this correct?

[parsibox]

and dear in client how can we receive incoming packet from each m3ua link? i think we need create listener, err := m3ua.Listen("m3ua", laddr, config) for each m3ua link , is this correct?

[wmnsk]

You'll need to monitor the Conn continuously, typically by calling Read in a for clause. If the link is closed or dead by some error the Read returns error. Write, on the other hand, is occasionally called when you need to send something (outgoing requests or replies to incoming requests). I think this answers both of your questions.

Tip: The Conn is implemented in similar way to other type of Conn in Go (TCP, UDP, etc.). I think it's nice for you to search how to implement a simple TCP/UDP client/server in Go first to learn the conventions.

thanks If you could add an example to the repository, it would be great, it would probably help other people a lot Thank you for your patience in answering

i found this for reading

func serve(conn *m3ua.Conn) {
    defer conn.Close()

    buf := make([]byte, 1500)
    for {
        n, err := conn.Read(buf)
        if err != nil {
            // this indicates the conn is no longer alive. close M3UA conn and wait for INIT again.
            if err == io.EOF {
                log.Printf("Closed M3UA conn with: %s, waiting to come back...", conn.RemoteAddr())
                return
            }
            // this indicates some unexpected error occurred on M3UA conn.
            log.Printf("Error reading from M3UA conn: %s", err)
            return
        }

        log.Printf("Read: %x", buf[:n])
    }
}
