Abstract

Network line speeds have increased at a significant rate. Unfortunately, network performance has not been able to keep pace with increases in line speed. This is due to the majority of packets being less than or equal to 100 bytes in addition to network routers not being able to scale well with the increased number of packets. In this paper we present our solution, JumboGen, an approach that will allow for a higher utilization of larger packet sizes on a domain-wise basis. Through simulations and experimentation, we show that the dynamic creation of jumbo packets decreases the number of packets processed by core routers and does not have an adverse impact on link utilization or fairness. The final result of JumboGen is a reduction in the number of packets seen by core routers which directly improves network scalability.
