Logistical Networking:Buffering in the Network
Prof. Martin Swany, Ph.D.Department of Computer and
Information Sciences
Network Logistics and Buffering• Logistics is time-related positioning of
resources• Buffers are temporary storage areas used
when transferring data• Storage has a continuum of persistence and
durability• Network devices have some buffer capacity• High-performance I/O depends on buffering
at various levels
Logistical Networking• Logistical Networking improves data movement
performance and functionality via buffering across a range of parameters and layers
• Logistical Session Layer / Phoebus• Plentiful, highly transitory, moderate capacity• Buffer duration from milliseconds to minutes• Implements “Store and Forward” along the end-to-end path
for improved throughput• Internet Backplane Protocol / REDDnet
• Less plentiful, more persistent, significant capacity• Buffer duration from minutes to months• Implements “Working Storage” used in general distributed
applications
Integrated LN Suite• Together, Phoebus and IBP implement
integrated buffering at all scales• Wide range of performance improvement
and functionality for scalable I/O and data movement• Pipelining• Caching
