Parameters:

id - task id

Method Details

addPacket

public VmPacket addPacket(Cloudlet destinationCloudlet,
long bytes)

Creates and adds a packet to the list of packets to be sent to a Cloudlet that is inside a specific VM.

Parameters:

destinationCloudlet - destination cloudlet to send packets to

bytes - the number of data bytes of the packet to create

Returns:

the created packet

Returns:

a read-only list of packets to send

getPacketsToSend

public List<VmPacket> getPacketsToSend(double sendTime)

Gets the list of packets to send, updating the send time to the given time and clearing the list of packets, marking the task as finished.

Parameters:

sendTime - the send time to update all packets in the list

Returns:
