Vadhiyar Yong Zheng Why Logistical Networking Analogy to military or industrial logistics Distributing goods requires not only highways but also warehouses (depots) Data transmission is the highway Storage servers are the depots Scalably sharable network storage Enabling new users and applications Internet Backplane Protocol (IBP) Servers that make

allocation of primitive byte arrays available to clients Byte arrays are not blocks (more abstract) Network capabilities (primitive security) Variable extents Byte arrays are not files (weaker semantics) Size & duration are limited Volatile allocations Best effort reliability and availability No directory structure, accounting No caching, replication An end-to-end approach to network storage Application Areas

Source routing Bandwidth adaption Reducing (BWdelay) Reliable multicast Content Distribution Data Grids Remote access to structured data Managing computation state (NetSolve caching) Temporary storage Very large data sets Collaborative computing & visualization

Dimensions in Communication Routing (spatial) Storage (temporal) Logistical Networking Logistical Networking PIs: Micah Beck, Jack Dongarra, James S. Plank / Tennessee; Rich Wolski / UCSB Logistical Networking SciDAC High Performance Networking Logistical Networking: Developing a communicative infrastructure with persistence Tasks: -develop/deploy network storage depots -develop layered storage stack & tools -develop/validate scheduling techniques -optimize application performance loci.cs.utk.edu Novel Ideas Storage is too cheap to hoard.

Storage can be a scalably shared network resource. Logistical Networking gives applications and middleware uniform control over buffering and routing of data. Data storage and data transport can be viewed as points on a spectrum of data management mechanisms. Monitoring and prediction can replace reservation as a means of scheduling storage resources. End-to-end networking principles can apply to storage. Impact and Connections IMPACT: Improved performance and scalability of data-intensive distributed application Greater ease of and lower cost of deployment of new wide area data management strategies Dramatically improved flexibility in data-intensive collaboration CONNECTIONS: SciDAC: Net100, Data Grid, Scalable Systems, Data Mgt, Computational Science (e.g. Climate, Supernovas) Base:Network Monitoring, Data Grid, Transport Protocols, Storage Res.
