org.cloudbus.cloudsim.network.HostPacket

All Implemented Interfaces:

NetworkPacket<NetworkHost>

public class HostPacket
extends Object
implements NetworkPacket<NetworkHost>

Represents a packet which travels from one Host to another. Each packet contains: IDs of the sender VM into the source Host and receiver VM into the destination Host which are communicating; the time at which it is sent and received; type and virtual IDs of tasks.
