Detailed Description

Route table class.

Contains a list and methods for manipulating the entries and its values, which correspond to different src-dst pairs (routes).

Constructor & Destructor Documentation

def RouteTable.Table.__init__	(		self,
			node_mac
	)

Constructor.

Parameters

self	The object pointer.
node_mac	MAC address of the node's network interface.

Returns

None

Member Function Documentation

def RouteTable.Table.get_avg_value	(		self,
			dst_ip
	)

Calculate and return the average estimation value of the given entry.

Parameters

self	The object pointer.
dst_ip	Destination IP address of the route.

Returns

Average estimation value. float().

def RouteTable.Table.get_entry	(		self,
			dst_ip
	)

Return current entry assigned for given destination IP.

Parameters

self	The object pointer.
dst_ip	Destination IP address of the route.

Returns

(Entry object) or None.

def RouteTable.Table.get_neighbors

(

self

)

Return the current list of neighbors.

Parameters

self	The object pointer.

Returns

List of current neighbors. list().

def RouteTable.Table.get_next_hop_mac	(		self,
			dst_ip
	)

This method selects a next hop for the packet with the given dst_ip.

The selection is being made from the current estimated values of the neighbors mac addresses, using some of the available action selection algorithms - such as greedy, e-greedy, soft-max and so on.

Parameters

self	The object pointer.
dst_ip	Destination IP address of the route.

Returns

(MAC address of the next hop) or None.

def RouteTable.Table.print_table

(

self

)

Print out the contents of the route table to a specified file.

Parameters

self	The object pointer.

Returns

None

def RouteTable.Table.update_entry	(		self,
			dst_ip,
			mac,
			reward
	)

Update the estimation value of the given action_id (mac) by the given reward.

Parameters

self	The object pointer.
dst_ip	Destination IP address of the route.
mac	MAC address of the neighbor (action ID).
reward	Reward value to be assigned.

Returns

None

Member Data Documentation

RouteTable.Table.action_selector

Create RL-helper rl_logic.ActionSelector object, to handle the process of action selection.

RouteTable.Table.current_node_ips

Store current ip addresses assigned to this node.

list().

RouteTable.Table.entries_list

Define list of current route entries.

Format: {dst_ip: Entry}.

RouteTable.Table.neighbors_list

Define a shared dictionary of current active neighbors.

This dictionary is also used by the ListenNeighbors class from the NeighborDiscovery module. Format: {mac: NeighborDiscovery.Neighbor object}.

RouteTable.Table.node_mac

MAC address of the node's network interface.

RouteTable.Table.table_filename

Define a filename to write the table entries to.

Default filename is "table.txt".
