3	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
4	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

6	Application Areas Source routing Bandwidth adaption Reducing (BW´delay) 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
