Packets¶

This module contains all packet definitions.

`Packet`(destination, source, timestamp)	Representation of a quantum of information
`DataPacket`(destination, source, timestamp, ...)	A packet used for transferring data
`RouterPacket`(source, timestamp, ...)	A packet used to update routing tables

Packet¶

class cs143sim.packets.Packet(destination, source, timestamp)[source]¶

Representation of a quantum of information

Packets carry information along the network, between Hosts or Routers.

Parameters:	destination – destination `Host` or `Router` source – source `Host` or `Router` timestamp (str) – time at which the packet was created
Variables:	destination – destination `Host` or `Router` source – source `Host` or `Router` timestamp (float) – time at which the packet was created size (int) – size of the packet

class cs143sim.packets.DataPacket(destination, source, timestamp, acknowledgement, number)[source]¶

A packet used for transferring data

DataPackets transmit data along the network, between Hosts or Routers.

Parameters:	destination – destination `Host` or `Router` source – source `Host` or `Router` timestamp (float) – time at which the packet was created acknowledgement (bool) – indicate whether the packet is an AckPacket number (int) – the number of the packet in a flow
Variables:	number (int) – the number of the packet in a flow acknowledgement (bool) – indicate whether the packet is an AckPacket

class cs143sim.packets.RouterPacket(source, timestamp, router_table, acknowledgement)[source]¶

A packet used to update routing tables

RouterPackets carry information of routing tables along the network, between Routers.

Parameters:	source – source `Host` or `Router` timestamp (float) – time at which the packet was created router_table (dict) – the routing table acknowledgement (bool) – indicate whether the packet is an AckPacket
Variables:	router_table (dict) – the routing table of the RouterPacket number (int) – the number of the RouterPacket, which is always 0 acknowledgement (bool) – indicate whether the packet is an AckPacket
