mockconn

Mock a network connection which has two endpoints to communicate. The connection implement of go standard library net.Conn interface

This network connection has configurable parameters as :

type ConnConfig struct {
    Addr1      string
    Addr2      string
    Throughput uint
    BufferSize uint
    Latency    time.Duration
    Loss       float32 // 0.01 = 1%
}

• Addr1: Address or any name to identify one endpoint, such as "Alice" or "127.0.0.1"
• Addr2: Address or any name to identify the other endpoint, such as "Bob" or an IP address
• Throughput: The Throughput (packet/second) you set for this connection. Each packet is default to 1024 bytes.
• BufferSize: The buffer size used in the network. It is suggest equal or greater than throughput.
• Latency: The duration which a packet travels in the connection.
• Loss: The rate of loss in the connection.

You can mock out a connection as:

conf := &ConnConfig{Addr1: "Alice", Addr2: "Bob", Throughput: uint(256), Latency: 100 *     time.Millisecond}
aliceConn, bobConn, err := NewMockConn(conf)

After mocking out the connection. You can begin send and receive data as:

• Writer

b := make([]byte, 1024)
// Todo: put meaningful data into b
n, err := aliceConn.Write(b)
if err != nil {
    return err
}

• Reader

b := make([]byte, 1024)
n, err := bobConn.Read(b)
if err != nil {
    return ree
}

After fininshing data transmitting and receiving all data, you may close this connection at both endpoints:

aliceConn.Close()
bobConn.Close()
