20090232143METHODS AND APPARATUS FOR USING MULTIPLE CONNECTION IDENTIFIERS BASED ON TRAFFIC REQUIREMENTS - Methods and apparatus related to scheduling and/or utilization of air link traffic resources are described. A peer to peer connection holds a set of multiple connection identifiers for a plurality of successive traffic slots. Corresponding to a particular traffic slot, each of the connection identifiers in the set of connection identifiers has a different priority. Short term traffic needs are considered in the use of the multiple connection identifiers being held. For example, a communications device, corresponding to a peer to peer connection which is associated with a plurality of connection identifiers having different priorities, considers the amount and/or latency requirements of data to be transmitted at any given time when selecting which connection identifier to use when transmitting a traffic transmission request for a traffic segment which is in contention.09-17-2009
20090232142METHODS AND APPARATUS FOR USING CONNECTION IDENTIFIERS HAVING DIFFERENT PRIORITIES AT DIFFERENT TIMES - Methods and apparatus related to scheduling and/or utilization of air link traffic resources are described. A connection identifier is associated with priority with regard to use of an air link resource, e.g., a peer to peer traffic segment which is in contention. A particular connection may acquire and hold one or multiple connection identifiers. In some embodiments, the priority associated with a particular connection identifier is intentionally varied in a set of traffic slots. In some such embodiments, there is priority randomization from slot to slot. In one such implementation there is a statistically uniform average priority between the different connection identifiers over the recurring structure. Such an implementation facilitates access to traffic segments to a wide range of users, yet allows for differentiation with regard to the amount of access as a function of the number of connection identifiers being held by a particular connection.09-17-2009
20100085973METHODS AND APPARATUS FOR IDENTIFYING AND/OR SELECTING A CONNECTION IDENTIFIER - Wireless terminals in a peer to peer system, which desire to communicate traffic signals, acquire a connection identifier associated with traffic transmission request air link resources.

A wireless terminal identifies locally available connection identifiers from a set of connection identifiers based on power received on individual connection identification transmission units in a set of connection identification transmission units; determines, for each group having an identified locally available connection identifier, an interference estimate; and selects a connection identifier from the identified locally available connection identifiers belonging to a group having an acceptable determined interference estimate.04-08-2010
20090016353CODING METHODS OF COMMUNICATING IDENTIFIERS IN PEER DISCOVERY IN A PEER-TO-PEER NETWORK - Systems and methodologies are described that facilitate identifying peers based upon encoded signals during peer discovery in a peer to peer network. For example, direct signaling that partitions a time-frequency resource into a number of segments can be utilized to communicate an identifier within a peer discovery interval; thus, a particular segment selected for transmission can signal a portion of the identifier, while a remainder can be signaled based upon tones communicated within the selected segment. Moreover, a subset of symbols within the resource can be reserved (e.g., unused) to enable identifying and/or correcting timing offset. Further, signaling can be effectuated over a plurality of peer discovery intervals such that partial identifiers communicated during each of the peer discovery intervals can be linked (e.g., based upon overlapping bits and/or bloom filter information).01-15-2009

20090041023Method and Apparatus for Interworking VPLS and Ethernet Networks - To allow seamless interworking between an 802.1ah service instance (ISID) and a VPLS service instance, the AGI value used to signal the setup of the pseudowire portion of the VPLS may carry the ISID value of an associated 802.1ah service instance. This allows the service instance to be identified end-to-end across the Ethernet and VPLS networks using the same value without modifying how the MPLS network operates. The VPLS network will use AGI/AII signaling to set up pseudowires on the MPLS network, but instead of using an AGI value assigned by the MPLS network, the AGI value that is assigned will be taken from the ISID value of the Ethernet frame or from ISIDs registered by the Ethernet network. The AGI message may be given a new type value indicating that the AGI message carries a value that corresponds to the ISID value on an attached Ethernet network. Alternatively, an existing AGI message type may be used to carry the ISID value, and a second type field may be used to indicate that the AGI contains an ISID value.02-12-2009

20080253377System and method for controlling process end-point utilizing legacy end-point system - Embodiments in accordance with the present invention allow a second end-point determination (EPD) system to actively control the end-pointing of a semiconductor process chamber, by leveraging a legacy EPD system that is already integrated with the chamber. In one embodiment, the second EPD system controls a shutter that regulates the amount of light transmitted between a plasma light source and an optical emission spectroscopy (OES) sensor of the legacy OES EPD system. In this embodiment, the legacy OES EPD system is pre-configured to call end-point when an artificial end-point condition occurs, i.e. the intensity of light falls below a pre-set threshold. When the second EPD system determines an actual end-point condition has been reached, it closes the shutter which, causes the light intensity being read by the OES sensor to fall below the pre-set threshold. This in turn triggers an end-point command to the chamber from the legacy OES EPD system.10-16-2008

20120287936EFFICIENT SOFTWARE-BASED PRIVATE VLAN SOLUTION FOR DISTRIBUTED VIRTUAL SWITCHES - Packet processing logic of a host system's virtualization manager detects packets on the ingress or the egress path to/from a virtual port having three bitmap arrays for processing packets within a virtual local area network (VLAN). The logic checks the VLAN identifier (VID) of the packet to determine, based on an offset position within the corresponding bitmap array, whether the port supports the VLAN. Both the ingress array offset position and egress array offset positions correspond to the value of the VID, and are set within the specific bitmap array during configuration of the VLAN on the port. When the VLAN is supported by the port, the logic enables the packet to be processed by the port. Otherwise, the logic discards the packet. A strip bitmap array indicates when a packet's VID should be removed prior to forwarding the packet on the egress of a port (or destination port).11-15-2012
