Uses of Packet in sime

Fields in sime declared as Packet

Modifier and Type	Field and Description
(package private) Packet	Router.OutputPort.packetInTransmission Holds the packet currently in transmission on the outgoing link.

Fields in sime with type parameters of type Packet

Modifier and Type	Field and Description
private java.util.ArrayList<Packet>	Router.packetBuffer Router memory for buffered/queued packets.
protected java.util.ArrayList<Packet>	Link.packetsFromN1toN2 Container for packets in transit from Link.node1 to Link.node2. We never check whether this array overflows, because we hope there will be never more than 100 packets in flight on a link?!?
protected java.util.ArrayList<Packet>	Link.packetsFromN2toN1 Container for packets in transit from Link.node2 to Link.node1. Similar to Link.packetsFromN1toN2.

Methods in sime with parameters of type Packet

Modifier and Type	Method and Description
protected void	Link.enqueueNewPacket(java.util.ArrayList<Packet> packets_, double[] packetDelays_, Packet packet_) Helper method to enqueue a new packet into one of the lists and calculate its delay on the link.
void	Router.handle(NetworkElement source_, Packet receivedPacket_) Buffers the incoming packet in the router memory.
abstract void	NetworkElement.handle(NetworkElement source_, Packet packet_) The method to receive packets from a lower-layer protocol.
void	Link.handle(NetworkElement dummySource_, Packet dummyPacket_) Link does not "handle" incoming packets, so this method does nothing.
void	Endpoint.handle(NetworkElement source_, Packet packet_) Handle the data segments received from the remote endpoint.
(package private) void	Router.OutputPort.handleIncomingPacket(NetworkElement source_, Packet receivedPacket_) Handles an incoming packet that is heading out on this output port.
void	Router.send(NetworkElement dummySource_, Packet dummyPacket_) Currently does nothing.
abstract void	NetworkElement.send(NetworkElement source_, Packet packet_) The method to send data from an upper-layer protocol. Note that parameter source_ is usually ignored but Link.send(NetworkElement, Packet) uses it to distinguish the nodes connected to its ends.
void	Link.send(NetworkElement source_, Packet packet_) The link just accepts any new packets given to it and enqueues the new packet behind any existing packets.
void	Endpoint.send(NetworkElement source_, Packet newDataPkt_) "Sends" segments by passing them to the network layer protocol object.

Method parameters in sime with type arguments of type Packet

Modifier and Type	Method and Description
protected void	Link.deliverArrivedPackets(java.util.ArrayList<Packet> packets_, double[] packetDelays_, NetworkElement node_, double lastTimeProcessCalled_) Helper method to deliver the packets that propagated through the link and arrived to the other end, if any. Note that we assume that the packets are enqueued on the first-come-first-served basis, so their delays are sorted in an ascending order.
protected void	Link.enqueueNewPacket(java.util.ArrayList<Packet> packets_, double[] packetDelays_, Packet packet_) Helper method to enqueue a new packet into one of the lists and calculate its delay on the link.

Uses of Packet in sime.tcp

Subclasses of Packet in sime.tcp

Modifier and Type	Class and Description
class	Segment TCP segment, which could carry either data, ACK, or both. Note that this class implements java.lang.Comparable so that TCP segments can be compared (and sorted) by their sequence number.
