Various embodiments of a system and method related to a topology and routing model for a peer-to-peer network are disclosed. A plurality of nodes may be coupled to each other to form a peer-to-peer network. A routing table may be created on each node in the peer-to-peer network. Each node may be operable to route messages to other nodes in the peer-to-peer network using information stored in the routing table. Messages may be propagated among nodes in the peer-to-peer network in a decentralized manner. For example, the peer-to-peer network may not utilize centralized servers of any kind. Each node in the peer-to-peer network may perform substantially the same routing functionality.

A method and system for implementing a global name space service. The method may include receiving a file system unique identifier corresponding to a particular file and a human-readable name corresponding to the same file. The method may further include binding the human-readable name to the file system unique identifier, thereby creating a mapping between the human-readable name and the file system unique identifier. The system may include a processor coupled to a memory and to a global name space service manager. The global name space service manager may be configured to receive a file system unique identifier corresponding to a particular file and a human-readable name corresponding to the same file. The global name space service manager may be further configured to bind the human-readable name to the file system unique identifier, thereby creating a mapping between the human-readable name and the file system unique identifier.
摘要:
A method and system for creating a peer-to-peer overlay network. The method includes discovering a set of node characteristics for each of a subset of existing nodes of a network. The method also includes scaling each of the discovered set of node characteristics to a value which is within a predetermined range of values. The method also includes generating a set of weighted values for each of the subset of nodes by applying a weighting function to each of the scaled values. In addition, the method includes generating a node rank value for each of the subset of nodes by summing the weighted values of each respective set of weighted values. Further, the method includes determining whether to connect to any of the subset of nodes based upon the node rank value.

Methods, and structures formed thereby, are disclosed for forming laterally grown structures with nanoscale dimensions from nanoscale arrays which can be patterned from nanoscale lithography. The structures and methods disclosed herein have applications with electronic, photonic, molecular electronic, spintronic, microfluidic or nano-mechanical (NEMS) technologies. The spacing between laterally grown structures can be a nanoscale measurement, for example with a spacing distance which can be approximately 1-50 nm, and more particularly can be from approximately 3-5 nm. This spacing is appropriate for integration of molecular electronic devices. The pitch between posts can be less than the average distance characteristic between dislocation defects for example in GaN (ρ=1010/cm2→d=0.1 μm) resulting an overall reduction in defect density. Large-scale integration of nanoscale devices can be achieved using lithographic equipment that is orders of magnitude less expensive that that used for advanced lithographic techniques, such as electron beam lithography.

Methods and systems for selectively connecting and disconnecting conductors in a fabric are disclosed. First and second conductors are integrated into a fabric such that the conductors intersect at a crossover point. The conductors are bonded to each other at the crossover point to improve AC and DC characteristics. Disconnect areas may be provided near the crossover point to allow selective disconnection of the conductors from the crossover point.

Coaxial and twisted pair conductive yarn structures reduce signal crosstalk between adjacent lines in woven electrical networks. A coaxial conductive yarn structure includes an inner conductive yarn having a plurality of conductive strands twisted together. An outer conductive yarn is wrapped around the inner conductive yarn. An insulating layer separates the inner and outer yarns. A twisted pair conductive yarn structure includes first and second conductive yarns, each including a plurality of conductive strands being twisted together. The first and second conductive yarns are twisted together to form a helical structure. In a woven electrical network, at least one conductor of adjacent conductive yarn structures is connected to ground to reduce signal crosstalk. Coaxial and twisted pair yarn structures may also be formed simultaneously with weaving or knitting the threads that make up the structures into a fabric.

Various embodiments of a system and method related to location-independent message addressing for a computer network are disclosed. According to one embodiment, a plurality of nodes, e.g., computer systems, may be connected to a network. The plurality of nodes may include a first node which is operable to send a message addressed using a “role”. The role may be associated with one or more other nodes coupled to the network. The message may be sent to each of the one or more nodes with which the role is associated without specifying locations of the one or more nodes. For example, the role may have an associated name, and the message may be addressed using the role name.

In-line fiber optic structure devices for use as environmental sensors and methods of fabricating in-line fiber optic structures as environmental sensors are disclosed and provided. According to some embodiments, fiber optic sensor devices can utilize the interaction of surface plasmons or evanescent waves with a surrounding environment.
