We describe FAST TCP, a new TCP congestion control algorithm for high-speed long-latency networks, from design to implementation.We highlight the approach taken by FAST TCP to address the four difficulties which the current TCP implementation has at large windows. We describe the architecture and summarize some of the algorithms implemented in our(More)
— We conducted various experiments using FAST TCP on two high-speed networks and uncovered some of the hidden problems affecting high-speed TCP implementations in practice. While FAST TCP achieved good performance in many scenarios, there were also a number of cases, where adverse conditions, both host related and network related, prevented it from(More)
It has been proved theoretically that a network with heterogeneous congestion control algorithms that react to different congestion signals can have multiple equilibrium points. In this paper, we demonstrate this experimentally using TCP Reno and Vegas/FAST. We also show that any desired inter-protocol fairness is in principle achievable by an appropriate(More)
The transcriptional mechanisms that drive colony-forming unit granulocyte-macrophage (CFU-GM) myeloid progenitors to differentiate into cells of either the granulocytic or monocytic lineage are not fully understood. We have shown that the c-Maf and c-Myb transcription factors physically interact in myeloid cells to form inhibitory complexes that hinder(More)
This document specifies extensions to OSPF to support the distributed computation of Maximally Redundant Trees (MRT). Some example uses of the MRTs include IP/LDP Fast-Reroute and global protection or live-live for multicast traffic. The extensions indicate what MRT profile(s) each router supports. Different MRT profiles can be defined to support different(More)
The network management problem is a very practical, yet complex and theoretically interesting problem. Understanding the problem requires exposure to the issues faced in managing a complex system. Given the lack of theoretical models for large-scale networks, we seek to understand the issues through data analysis. Toward this end, we are using the Access(More)
