Ramesh Sitaraman is an Indian American computer scientist currently in the computer science department at University of Massachusetts Amherst.[3] He is known for his work on distributed algorithms, content delivery networks, streaming video delivery, and application delivery networks.

Biography[edit]

Ramesh Sitaraman received a B.Tech in Electrical Engineering from the Indian Institute of Technology, Madras and a Ph.D in computer science from Princeton University.[1] In the past, he helped build Akamai's high-performance network for delivering web and media content [1] and is an Akamai Fellow.[4][5] Currently, he is at the computer science department at University of Massachusetts, Amherst.

Research Interests[edit]

Sitaraman's early research centered on algorithms for building reliable parallel networks from unreliable components by emulating a virtual overlay network on top of an underlying unreliable parallel network.[6][7] Later, serving as a principal architect,[8] he helped build the Akamai network,[7] a large overlay network that currently delivers 15-30% of all web traffic using 190,000 servers in 110 countries in over 1,100 networks.[9] He is known for helping pioneer Iarge distributed networks for web content delivery, streaming media delivery, and application delivery on the Internet.[7][10] His current research is focused on energy efficiency of Internet-scale distributed networks.[5][11] He is also known for his early work in building large-scale video delivery networks,[8] measuring their performance,[12] and more recently studying the impact of streaming video performance on users.[13][14][15][16][17]
