1 Performance Implications of a Bounded Receive Buffer In Concurrent Multipath Transfer (2010)

Janardhan R. Iyengar, Paul D. Amer, Randall Stewart

Abstract — We study the performance of Concurrent Multipath Transfer using SCTP multihoming (CMT) in the presence of a bounded receive buffer (rbuf). We demonstrate using simulation that if two...

IMPROVING FILE TRANSFER IN FCS NETWORKS* (2009)

Sourabh Ladha, Paul D. Amer, O L. Caro, Janardhan R. Iyengar

We compare the performance of two transport protocols, SCTP and the New-Reno variant of TCP, for file transfers in two FCS networking scenarios. We argue why SCTP is better suited for file transfers...

ABSTRACT We propose CMT- Concurrent Multipath Transfer using the Stream Control Transmission Protocol (SCTP). CMT (2009)

Janardhan R. Iyengar, Keyur C. Shah, Paul D. Amer, Randall Stewart

Abstract. Previously, we identified the failure-induced receive buffer (rbuf) blocking problem in Concurrent Multipath Transfer using SCTP multihoming (CMT), and proposed CMT with a...

Dealing with Short TCP Flows: A Survey of Mice in Elephant Shoes (2008)

Janardhan R. Iyengar, O L. Caro, Paul D. Amer

Short web transfers that dominate the Internet suffer from TCP’s inadequate provisioning for short flows. This paper surveys ten proposals that attempt to solve one or more of the problems of short...

Janardhan R. Iyengar, Keyur C. Shah, Paul D. Amer

uses SCTP’s multihoming feature to simultaneously transfer new data across multiple end-to-end paths to the receiver. Through ns-2 simulations, we observe significant reordering at the receiver due...

End-to-end concurrent multipath transfer using transport layer multihoming [electronic resource] / (2006)

Iyengar, Janardhan R.

Transport layer multihoming binds a single transport layer association to multiple network addresses at each endpoint, thus allowing the two end hosts to communicate over multiple network paths. This...

Preethi Natarajan, Janardhan R. Iyengar, Paul D. Amer, All Stewart

Recent research on Concurrent Multipath Transfer using SCTP multihoming (CMT) proposed various retransmission policies to minimize the negative impacts of receiver buffer (rbuf) blocking that occur...

SCTP: An Innovative Transport Layer Protocol for The Web (2006)

Preethi Natarajan, Janardhan R. Iyengar, Paul D. Amer, All Stewart

We propose using the Stream Control Transmission Protocol (SCTP), a recent IETF transport layer protocol, for reliable web transport. Although TCP has traditionally been used, we argue that SCTP...
