摘要： A coding approach for a robust and flexible network communication protocol is described. By using coding, it is possible to eliminate the need to track packet identities, and hence, it is possible to reduce coordination overhead associated with many conventional protocols. The method and system described herein takes advantage of multiple paths, interfaces, mediums, servers, and storage locations available in a network. The proposed protocol allows quick response to congestion by load balancing over different network resources. The method also enables soft vertical hand-overs across heterogeneous networks. In one embodiment, a media file is divided into chunks and transmitted using a transport protocol tailored to meet delay requirements of media streaming applications. Also described are different coding strategies for chunk delivery based upon an urgency level of each chunk.

摘要： Subject matter disclosed herein relates to random linear network coding schemes for reliable communications for time division duplexing channels. In at least one embodiment, a transmitter node transmits M data packets through a half-duplex link using random linear network coding. The transmitter node transmits coded packets back-to-back through the link before stopping to wait for an acknowledgement (ACK) packet. An optimal number of coded packets Ni to be transmitted in a subsequent transmission may then be determined based, at least in part, on a number of degrees of freedom (DOFs) a receiving node needs to decode the M information packets from received coded packets.

摘要： A method, apparatus and computer program product for providing rapid information dissemination using network coding is presented. A coded message including a payload and a code vector, is transmitted from a first node of the network to a second node of the network. The information thus stored can also be retrieved by collecting code vectors from at least one node and viewing the collected code vectors as a matrix. A determination is made regarding whether a dimension of the matrix is equal to a predefined number. When the dimension of the matrix equals the predefined number, the information is retrieved using the collection of code vectors in the matrix.

摘要： A network and a method for transmitting processes in a network are disclosed, where a randomized coding approach is provided. Network nodes transmit on each outgoing link a linear combination of incoming signals, specified by independently and randomly chosen code coefficients from a finite field. The approach allows robust, distributed transmission and compression of information in networks and is advantageous over routing-based approaches.

摘要： A system for simultaneously transmitting and receiving multiple data messages on a unidirectional ring having a plurality of nodes coupled thereto is described. This technique utilizes a medium access (MAC) protocol for a multi-gigabit-per-second local-area optical wavelength division multiplexed (WDM) network that is particularly well suited for high-performance computing environments that need a network that provides quality of service and the ability to enforce service level agreements. The protocol uses an asynchronous, unslotted, tokenless, and collision-free access scheme that is arbitrated by a centralized scheduler. The embodiment is based on a folded-bus unidirectional ring that is passively optically tapped by the nodes to both transmit data onto the network and to receive data from the network. The system includes a scheduler based on a master/slave protocol that provisions and regulates data flow on the network, and uses a dedicated out-of-band control wavelength to broadcast scheduler directives to the nodes in the network.

摘要： A fiber-optic networking system that can survive a break in the fiber and restore full connectivity to all nodes in the network. The network can detect the presence of a cut in the fiber, locate the cut, recover from the cut, and restore the communication capacity that was available before the cut. The network is also capable of automatically determining the existence and identity of the nodes in the network, the distance of the node from the headend, and the executing procedures to handle both planned and unplanned (i.e., during a fault) removal of nodes from the network.

摘要： A FAWNA that allows high-speed mobile connectivity by leveraging the speed of optical networks. Specifically, SIMO FAWNA, which comprises a SIMO wireless channel interfaced with a fiber channel through wireless-to-optical interfaces. Received wireless signal at each interface are sampled and quantized prior to transmission. The capacity of the FAWNA approaches the capacity of the architecture exponentially with fiber capacity. It is also shown that for a given fiber capacity, there is an optimal method of operating wireless bandwidth and number of interfaces. An optimal method to divide the fiber capacity among the interfaces is shown, which ensures that each interface is allocated a rate so that noise is dominated by front end noise rather than by quantization distortion. A method is also presented in which, rather than dynamically changing rate allocation based on channel state, a less complex, fixed rate allocation may be adopted with very small loss in performance.

摘要： A method and computer program product for providing a random linear coding approach to distributed data storage is presented. A file is broken into a plurality of pieces. For every peer (peer means storage-location with limited storage space), the number of coded-pieces the peer can store is determined. Each of the coded-piece is detrmined by taking random linear combination of all the pieces of the entire file. The associate code-vector is stored for every coded-piece. The file is retrieved by collecting code-vectors and the coded-pieces from the peers and viewing the collected code-vectors as a matrix. When a dimension of the matrix is equal to the number of pieces of the file, the file is recovered using the collection of code vectors in the matrix.

摘要： Apparatus and techniques for detecting malfunctions, anomalies and attacks upon optical devices of a transparent all-optical network, including amplified links and optical nodes, of the network. A portion of an input signal of the optical device and a portion of an output signal from the optical device are coupled to an optical processing unit and a an optical to electrical signal converter. The electrical output signal of the converter is coupled to an electronic processing unit which generates a difference signal which is a function of the input and output signal portions for comparison to a predetermined set of parameters. The result of the comparison is an alarm signal indicative of the occurrence of a malfunction. Also described is an optical comparator capable of generating the difference signal which is indicative of perturbations in the optical device.
