Networking and the Network Storage Stack
This talk will detail the research program at the Logistical Computing
and Internetwork Laboratory at the University of Tennessee. Specifically,
we will detail our novel approach to network storage, which adheres to
end-to-end design principles, and thus promises the ability to insert
writable storage into the network as a scalable, shared resource. We term
the paradigm of utilizing network storage to augment communication in
the network "logistical networking."
Using the IP stack as our guide, we have developed a Network Storage
Stack as a way for applications to make use of network storage. The central
pieces of that stack are:
- The Internet Backplane Protocol (IBP), for allocation and basic storage
- The exNode, for aggregation of multiple allocations.
- The L-Bone for storage server discovery and network proximity querying.
- The Logistical Runtime System (LoRS), for providing strong storage
properties from the weak guarantees of IBP allocations.
We will describe the stack in detail, present applications that make
use of it, and give performance results. We will also demonstrate "Video
IBPster," an application that stores and plays video files from faulty,
transient, wide-area network storage depots. We will conclude with future
James S. Plank received his B.S. from Yale University in 1988
and his Ph.D. from Princeton University in 1993. He is currently an associate
professor in the Computer Science department at the University of Tennessee.
His research interests are in fault-tolerance, checkpointing, and network
storage. He is a member of the IEEE Computer Society.
Micah Beck received has been a contributor to research ranging
from Parallel and Distributed Systems to Languages and Compilers to Advanced
Internetworking and Storage Architecture. He began his career doing research
in distributed operating systems at Bell Laboratories and received his
Ph.D. in Computer Science from Cornell University (1992) in the area of
parallelizing compilers. He then joined the faculty of the Computer Science
Department at the University of Tennessee, where he is currently an Associate
Professor working in distributed high performance computing, networking
and storage; he is also a Director of the Logistical Computing and Internetworking
Laboratory. An active participant in the Internet2 project, he has since
1997 led their Distributed Storage Infrastructure project, defining an
advanced Content Distribution model to enable edge processing. In 2000
he joined with other members of this project drawn from industry and academia
to found Lokomo Systems and he currently serves as Chief Scientist of
