Function Documentation

_declspec()

_declspec

(

dllexport

)

This function is used receive the updates from neighbor routers.

Function to copy the RIP packet from source to destination.

Function to free the allocated memory for the RIP packet.

Return the subevent name with respect to the subevent number for writting event trace.

Function to free the RIP protocol variable and Unload the primitives.

This function is used to trigger the update.

Function for configuring RIP parameters

Function for Intializing RIP protocol

Function to run RIP protocol

fn_NetSim_RIP_CopyPacket_F()

NetSim_PACKET *int fn_NetSim_RIP_CopyPacket_F	(	NetSim_PACKET *	,
		NetSim_PACKET *

Here is the caller graph for this function:

fn_NetSim_RIP_DistanceVectorAlgorithm()

int fn_NetSim_RIP_DistanceVectorAlgorithm	(	struct stru_NetSim_Network *	NETWORK,
		NetSim_EVENTDETAILS *	pstruEventDetails
	)

This function runs the distance vector routing algorithm for optimized routing of packets from 
source to destination. The optimization is done per a particular metric, i.e the shortest distance.
This algorithm runs inside a single Autonomous System

fn_NetSim_RIP_Garbage_Collection_Timer()

int fn_NetSim_RIP_Garbage_Collection_Timer	(	struct stru_NetSim_Network *	pstruNETWORK,
		NetSim_EVENTDETAILS *	pstruEventDetails
	)

Until the garbage-collection timer expires, the route is included in all 
updates sent by the router. When the garbage collection timer expires, the route is deleted 
from the routing table

fn_NetSim_RIP_Timeout_Timer()

int fn_NetSim_RIP_Timeout_Timer	(	struct stru_NetSim_Network *	pstruNETWORK,

	)

The timeout is initialized when a route is established, and any time 
an update message is received for the route. If 180 seconds elapse from
the last time the timeout was initialized, the route is considered to 
have expired

int fn_NetSim_RIP_Update_Timer	(	struct stru_NetSim_Network *	pstruNETWORK,
		NetSim_EVENTDETAILS *	pstruEventDetails
	)

Every 30 seconds, the RIP process is awakened to send an unsolicited response message 
containing the complete routing table to every neighboring router.
 
    1. Create the RIP packet
    2. Add the RIP packets in the WAN ports of the current router
    3. Add the packet in the socket buffer for transmitting the RIP packet
