![]() ![]() Extensive packet-level simulations show that XCP outperforms TCP in both conventional and high bandwidth-delay environments. Using a control theory framework, we model XCP and demonstrate it is stable and ef cient regardless of the link capacity, the round trip delay, and the number of sources. This allows a more exible and analytically tractable protocol design and opens new avenues for service differentiation. In addition, XCP introduces the new concept of decoupling utilization control from fairness control. This new eXplicit Control Protocol, XCP, generalizes the Explicit Congestion Noti cation proposal (ECN). To address this problem, we develop a novel approach to Internet congestion control that outperforms TCP in conventional environments, and remains ef cient, fair, scalable, and stable as the bandwidth-delay product increases. This failing becomes increasingly important as the Internet evolves to incorporate very high-bandwidth optical links and more large-delay satellite links. Further, XCP achieves fair bandwidth allocation, high utilization,Ĭongestion Control for High Bandwidth-Delay Product Networks Dina Katabi£ Mark Handley Charlie Rohrs MIT-LCS ICSI Tellabs ABSTRACT Theory and experiments show that as the per- ow product of bandwidth and latency increases, TCP becomes inef cient and prone to instability, regardless of the queuing scheme. It is designed to drive power MOSFETs, IGBTs, and SiC MOSFETs up to 5-MHz with best-in-class propagation delay and pulse-width distortion. Extensive packet-level simulations show that XCP outperforms TCP in both conventional and high bandwidth-delay environments. The UCC21520 and the UCC21520A are isolated dual-channel gate drivers with 4-A source and 6-A sink peak current.
