Improvements and perspectives

The current implementation of the vrouter is different from the original specification provided by Professor Shinoda, However all the requested functionalities of the vrouter are implemented and the liberty to have a multiple independant networking stack was taken. The future improvements can consist in optimising the program (memory allocation, and fastness ) by rewriting some code and tuning the delays and timing intervals. It will be a good idea also to improve the protocols implementation to better fit the standard specification, indeed the VRIP for example does not implement yet the VRIP entries expiration, in the other hand the IP protocol does not implement packet fragmentation yet. Added to that we can also implement new functionalities based on the multiple networking stack characteristic of the program.
Here is a list to summarize what could be done :

• Improve the protocols implementations ; VRIP entries expiration and VIP packet fragmentation.
• Tune the internal definded delays uded for shceduling events and timing entries, inorder to have optimized network bandwith usage and cpu consumption.
• A feature like multiple routing tables ( one per interface could be implemented ).
• Implement different network layer protocol than IP and use the vrouter as a bridging entity.
• Implement ICMP protocol to allow better network control and debugging.
• Implement the UDP transport layer.
