Abstract: A method for assisting in a handover is provided that includes utilizing a link between a centralized access controller (CAC) and customer premises equipment (CPE) to facilitate a communication session involving a mobile station. The method also includes rejecting a handover from a public network to a cell controlled by the CAC after recognizing, in advance, that sufficient resources are unavailable for supporting a channel to be employed for the handover.

Abstract: A method and system is disclosed for passing a transmit/receive control signal and a power signal through a coax cable from a base transceiver station to a tower top device in a time division duplex communication system. After generating the transmit/receive control signal and a radio frequency signal for communications, the transmit/receive control signal modulates a separate timing control operating on a separate control frequency. It is then multiplexed on at least one coax cable along with the radio frequency signal and DC power. At the tower top device, the modulated transmit/receive control signal is converted back to a DC level for providing a time division duplex control reference.

Abstract: A data center provides secure handling of HTTPS traffic using backend SSL decryption and encryption in combination with a load balancer such as a content switch. The load balancer detects HTTPS traffic and redirects it to an SSL offloading device for decryption and return to the load balancer. The load balancer then uses the clear text traffic for load balancing purposes before it redirects the traffic back to the SSL offloading device for re-encryption. Thereafter, the re-encrypted traffic is sent to the destination servers in the data center. In one embodiment, the combination with the back-end SSL with an intrusion detection system improves security by performing intrusion detection on the decrypted HTTPS traffic.

Abstract: A system (e.g., Fiber Channel Error Detecting Code (FC-EDC)) that maps the “standard” Hamming codes onto the bits of a 33-bit control block is provided. The system employs a “rotation” of the check positions in a two-dimensional parity-check matrix for the FC-EDC. The specification discloses a computer-implemented program to test further modifications and permutations of the “standard” distance-4 parity-check matrix to yield an FC-EDC with enhanced error-detecting properties, designed to detect the most likely errors in the known physical environment. By using a parity-check matrix with the “rotation” property, certain error-detecting properties of the parity-check matrix are ensured, and the computation time for searching for a matrix with enhanced error-detecting properties becomes much shorter.

Abstract: Disclosed are methods and apparatus for selectively filtering data messages that are communicated between a head end complex and its associated cable modems. Filtering includes obtaining a copy of the message and sending the copied message to a memory device. The memory device is accessible, for example, via a user so that the filtered message may be analyzed. In a preferred embodiment, the memory device is a monitoring device in the form of a computer system (e.g., a router). Messages may be filtered to the memory or monitoring device based on any suitable filtering criteria that identifies specific message parameters. In a specific embodiment, filtering may be based on one or more message types. When filtering criteria specifies a particular message type, messages having such a specified type are filtered to the monitoring station. Additionally or alternatively, filtering may be based on one or more values of a particular field of the message.

Abstract: Particular embodiments provide an optimal allocation of a bearer manager or home agent. In one embodiment, a message is received from a mobile node requesting access to a visiting network that is different from a home network for the mobile node. An authentication request is sent to the home network requesting authentication for access. The authentication request indicates that a home agent has not been assigned. The home AAA server then sends a response that indicates the visiting AAA server can assign a home agent for the mobile node. The visiting AAA server then assigns a home agent that is optimally determined. The visiting home agent is different from a home agent that is found in the mobile node's home network. When a registration request is received, an IP gateway may send the registration request to the visiting home agent, which may not be sent back to the home network.

These link authentication protocol exchanges can be initiated at substantially the same time. A first network device acts as an authenticator in a first one of the link authentication protocol exchanges and a supplicant in a second one of the link authentication protocol exchanges. One of the link authentication protocol exchanges is terminated prior to completion.

Abstract: An input/output processor for speeding the input/output and memory access operations for a processor is presented. The key idea of an input/output processor is to functionally divide input/output and memory access operations tasks into a compute intensive part that is handled by the processor and an I/O or memory intensive part that is then handled by the input/output processor. An input/output processor is designed by analyzing common input/output and memory access patterns and implementing methods tailored to efficiently handle those commonly occurring patterns. One technique that an input/output processor may use is to divide memory tasks into high frequency or high-availability components and low frequency or low-availability components.

Abstract: Each network node in a network is configured for calculating a directed acyclic graph that provides at least one path from all the other network nodes toward the one network node. The network node performs a modified shortest path first calculation by identifying next-hop nodes adjacent to the network node, and orienting the link of each next-hop node toward itself (i.e., the origin). The network node also identifies secondary adjacent nodes, adjacent to each of the next hop nodes, and extends paths from next-hop nodes to the associated secondary adjacent nodes while orienting each of the links of the path between adjacent nodes and next-hop nodes toward the next hop nodes. The paths of the nodes form a directed acyclic graph from any other network node toward the origin, enabling distribution of the directed acyclic graph to the other network nodes for optimized reachability to the network node.
