Logistical Networking can be defined as the global optimisation and scheduling of data storage, data movement, and computation. It is a technology for shared network storage that allows an easy scaling in terms of the size of the user community, the aggregate quantity of storage that can be allocated, and the distribution breadth of service nodes across network borders.

After describing the base concepts of Logistical Networking, we will introduce the Internet Backplane Protocol, a middleware for managing and using remote storage through allocation of primitive ``byte arrays'', showing a semantic in between buffer block and common files. As this characteristic can be too limiting for a large number of applications, we developed the exNode, that can be defined, in two words as an inode for network distributed files. We will introduce then the Logistical Backbone, or L-Bone, which is a distributed set of facilities that aim to privide high-performance, location- and application-independent access to storage for network and Grid applications of all kinds.

Keywords: Logistical Networking, IBP, storage-enabled Internet.
