Constructor Detail

ReliableTransport

public ReliableTransport(java.lang.String prefix)

Instantiates a new reliable transport.

Parameters:

prefix - the prefix

Method Detail

clone

public ReliableTransport clone()

Returns this. This way only one instance exists in the system that is linked from all the nodes. This is because this protocol has no node specific state.

Specified by:

clone in interface peersim.core.Protocol

Overrides:

clone in class java.lang.Object

Returns:

the reliable transport

send

public void send(peersim.core.Node src,
                 peersim.core.Node dest,
                 java.lang.Object msg,
                 int pid)

Sends the message.

Specified by:

send in interface peersim.transport.Transport

Parameters:

src - the src

dest - the dest

msg - the msg

pid - the pid

getLatency

public long getLatency(peersim.core.Node src,
                       peersim.core.Node dest)

Returns the latency of the network.

Specified by:

getLatency in interface peersim.transport.Transport

Parameters:

src - the src

dest - the dest

Returns:

the latency
