Method Detail

doInit

protected void doInit()

rdtp.doInit() is invoked to perform protocol-dependent initialization for this AlternatingBitProtocol.

Specified by:

doInit in class RDTProtocol

handleNewSegment

public void handleNewSegment(int id)

handleNewSegment(id) is invoked to handle a new segment with identification number id. The identification number is just a stand-in for the real data in a segment. It is used by the Logger for recording purposes.

Specified by:

handleNewSegment in class RDTProtocol

handleReceivedData

public void handleReceivedData(Packet pkt)

handleReceivedData(pkt) is invoked to handle a DATA_TYPE packet received from its TCPEntity's connection partner.

Specified by:

handleReceivedData in class RDTProtocol

handleReceivedAck

public void handleReceivedAck(Packet pkt)

rdtp.handleReceivedAck(pkt) is invoked to handle a ACK_TYPE packet received from its TCPEntity's connection partner.

Specified by:

handleReceivedAck in class RDTProtocol

handleTimedOutPacket

public void handleTimedOutPacket(Packet pkt)

rdtp.handleTimedOutPacket(pkt) is invoked to handle a packet acknowledgement timeout for pkt. pkt may be null for protocols that use a single timer.

Specified by:

handleTimedOutPacket in class RDTProtocol
