Protocols for Wide-Area Data-Intensive Applications - Design and Performance Issues
SESSION: Grids/Clouds Networking
EVENT TYPE: Papers
TIME: 3:30PM - 4:00PM
SESSION CHAIR: Michael Lang
AUTHOR(S):Yufei Ren, Tan Li, Dantong Yu, Shudong Jin, Thomas Robertazzi, Brian Tierney, Eric Pouyoul
ROOM:255-EF
ABSTRACT:
Providing high-speed data transfer is vital to various data-intensive
applications. While there have been remarkable technology advances to
provide ultra-high-speed network bandwidth, existing protocols and
applications may not be able to fully utilize the bare-metal bandwidth
due to their inefficient design. We identify the same problem remains
in the field of Remote Direct Memory Access (RDMA) networks. RDMA
offloads TCP/IP protocols to hardware devices. However, its benefits
have not been fully exploited due to the lack of efficient software
and application protocols, in particular in wide-area networks. In
this paper, we address the design choices to develop such
protocols. We describe a protocol implemented as part of a
communication middleware. The protocol has its flow control,
connection management, and task synchronization. It maximizes the
parallelism of RDMA operations. We demonstrate its performance
benefit on various local and wide-area testbeds, including the DOE ANI
testbed with RoCE links and InfiniBand links.
