Abstract: Techniques are disclosed for using Ethernet Layer 1 as a means for transporting audio, control, and status signals between telephones and an aggregator device in a telephone system. Techniques are also disclosed for using the aggregator to determine whether a telephone supports only Ethernet Layer 1, and for using the aggregator to communicate with the telephone using an appropriate protocol based on the results of the determination.

Abstract: A stack of network routers is composed of at least one (elected) master unit and one or more slave units each capable of running a routing protocol. Only the master unit runs the entire routing protocol at a given time. It forwards direct update messages via a transmission control protocol to each of the slave units. These direct update messages may include specific packet formats for the protocol state machinery where such machinery is required by the routing protocol, e.g., the interface state machine and the neighbor state machine for the OSPF protocol, and for the net databases, e.g. the link state databases for the OSPF protocol, in each of the slave units. Each slave unit may run its protocol state machinery (where provided) based purely on the direct update messages received from the master. The synchronisation of the net databases may be based on snooping net update packets and a comparison of the information received thereby with verification data messages sent from the master unit.

Abstract: Inquiry data received from sequential target devices is stored in a cache memory. In one embodiment, the cache memory is coupled to a router. In one embodiment, when the router receives from a host an inquiry command about a target, the router first checks to see if the inquiry command can be serviced from the cache. If so, the inquiry data about the target is retrieved from the cache and returned to the host. If not, the router checks to see if the target is busy. If not busy, the router routes the inquiry command to the target and stores the inquiry data returned by the target in the cache. If the target is busy, the router places the inquiry command in a queue. When the target becomes available, the router forwards the inquiry command to the target for processing, thereby keeping the inquiry command from timing out.

Abstract: One embodiment of the invention includes a method of managing network communications in a network device. The network device includes software components and modules. Some of the components control the interaction between modules, while other components perform specific functions for associated modules. A module manager component controls the creation and destruction of modules as well as their interactions. A communications manager component manages network communications in the network device. The network communications is supported by creating a number of modules that are associated with components that implement different parts of a network protocol. As a result of the use of the modules, a component need not know which other component(s) it depends upon, nor need it know which other component(s) depend upon it. This allows components to be used together very easily in many different configurations. The modules also allow the same component to be used by multiple modules.

Abstract: A data processing system adapted for high-speed network communications, a method for managing a network interface and a network interface for such system, are provided, in which processing of packets received over the network is achieved by embedded logic at the network interface level. Incoming packets on the network interface are parsed and classified as they are stored in a buffer memory. Functional logic coupled to the buffer memory on the network interface is enabled to access any data field within a packet in a single cycle, using pointers and packet classification information produced by the parsing and classifying step. Results of operations on the data fields in the packets are available before the packets are transferred out of the buffer memory.

Abstract: A technique is disclosed to schedule frame transmissions in a wireless local area network. The network includes a plurality of stations configured to communicate on the same frequency channel with a plurality of access points. A central controller examines the transmission characteristics between the various stations and access points and identifies frames that may be simultaneously transmitted by a subset of the access points to their intended stations.

Abstract: A capacitive sensor includes first and second variable capacitor electrode sets, respectively disposed upon a planar support surface and a proof mass that is compliantly displaceable along a first axis substantially parallel to the planar support surface. The first electrode set produces a cyclic variation in capacitance over a range of displacement of the proof mass along the first axis, and the second electrode set produces an absolute capacitance variation throughout the range of displacement along the first axis.

Abstract: A fast roaming (handoff) service is provided for a WLAN infrastructure. A given mobile station (STA) obtains a pairwise master key (PMK) when it associates with an access point (AP) in the infrastructure. A neighbor graph identifies prospective APs to which the STA may then roam. At initialization, preferably the neighbor graph is fully-connected (i.e., each AP is assumed to be connected to every other AP). The PMK (obtained by the STA initially) is shared proactively with the neighbor APs as indicated in the neighbor graph. Thus, when the STA roams to a neighbor AP, because the PMK is already available, there is no requirement that the STA initiate a real-time request to an authentication server to re-associate to the new AP.

Abstract: A plurality of virtual paths in a network interface between a host port and a network port are managed according to respective priorities using dynamic buffer allocation. Thus, multiple levels of quality of service are supported through a single physical network port. Variant processes are applied for handling packets which have been downloaded to a network interface, prior to transmission onto the network. The network interface also includes memory used as a transmit buffer, that stores data packets received from the host computer on the first port, and provides data to the second port for transmission on the network. A control circuit in the network interface manages the memory as a plurality of first-in-first-out FIFO queues having respective priorities. Logic places a packet received from the host processor into one of the plurality of FIFO queues according to a quality of service parameter associated with the packets.

Abstract: A method and system for network based call-pickup is provided. In one embodiment a first user agent communicates in a communication session with a second user agent in a network telephony system. The second user agent may request that a third user agent replace the second user agent in the communication. The third user agent may be a park server, and when it replaces the second user agent, the communication session may thereby be parked at the park server. A fourth user agent may then request that the third user agent (e.g., park server) initiate a communication session between the first user agent and the fourth user agent. The third user agent may then instruct the first user agent to communicate with the fourth user agent. The parked communication session may thereby be picked up by the fourth user agent.

Abstract: Deciphering and verification of the checksum of enciphered and encapsulated UDP datagrams, particularly those which enclose a tunneling protocol such as L2TP, are achieved by the provision of a checksum verifier in parallel with a decipher block. Checksum logic creates a pseudo UDP header needed for checksum verification using fields that would occur at the start of the packet that encapsulates the UDP datagram. The first part of the packet to be deciphered is the UDP header; checksum logic can latch the checksum field into a local register. As the rest of the packet is deciphered the checksum verifier processes the data at the same time. Eventually the checksum logic will acquire a complete checksum which can be compared with the checksum that had been previously latched, so as to verify the checksum.

Abstract: A method includes capturing a first image of a display surface with an image capture device, the display surface having a first plurality of fiducial marks. A first smoothing function is performed on fiducial marks appearing in the first image, thereby generating a first regularized set of fiducial marks having a smooth variation in spacing between adjacent fiducial marks. A first plurality of meshes is generated based on the first regularized set of fiducial marks. The first plurality of meshes is configured to map a first domain associated with the display surface to a second domain associated with the image capture device.

Abstract: A method for offloading encryption and decryption of a message received at a message server to one or more end devices that are remote from the message server. An encrypting end device remote from the message server encrypts a message using cryptographic context and transmits the cryptographic context and encrypted message to the message server for storage at the message server. The message server stores the encrypted message as received without decrypting the message. The message server sends the stored cryptographic context and the encrypted message to a decrypting end device in response to the decrypting end device sending a request for the message server to transmit the encrypted message to the decrypting end device. The decrypting end device uses the cryptographic context to decrypt the encrypted message and then presents the decrypted message to a user of the decrypting end device.

Abstract: A remote management controller may include a capture engine and a processor. The capture engine may be configured to obtain a slice of video data output from a video graphics controller, store the slice of video data, and calculate at least one value correlative to the slice of video data. The processor may be configured to retrieve the slice of video data stored by the capture engine and process any changed portion of the slice of video data for transmission to a remote system.

Abstract: The deciphering of fragmented enciphered IP packets is performed without requiring reassembly of the fragments. fragmented packets. When a first frame is deciphered a characteristic poly-tuple is saved against the state of the cipher, particularly an output vector. When the next frame comes in, the cipher would continue on from that previously saved state after a look-up of the poly-tuple. Each frame would then be sent on, deciphered, but still representing a fragment of the original packet. The poly-tuple employed for the look-up includes the identity and protocol fields from the IP header and at least one of the source IP address and the destination IP address. The deciphering process may commence with the combination of input data with an initializing vector and proceed by combining input data with a vector fed back from the output of the deciphering engine. The saved cipher state is employed as the initializing vector for the next frame.
