Most of the existing crypto drivers cannot operate effectively over the multi-core systems, resulting in high synchronization overheads. Moreover, the crypto drivers under utilize the full capacity of the hardware device underneath, resulting in low IPsec throughput. This paper discusses a design methodology that virtualizes the access to the common crypto accelerators across the multiple cores and...
TCP's interaction with a token bucket policer has been widely studied. However, it still remains a challenge to design a policer which can optimize performance irrespective of the traffic type, load and level of aggregation being policed. In this paper we propose an improvement to the token bucket policer using a dynamic bucket size. Our novel scheme presents a specific and effective way to continuously...
Almost all traffic in today's networks can be classified as being either stream or elastic. The support of these two traffic types is possible either with a Differentiated (DiffServ) or Integrated Services (IntServ) architecture. However, both DiffServ and IntServ rely on efficient scheduling mechanisms and traffic control to meet the requirements of these traffic types. In order to meet the strict...
