Abstract: In one embodiment, a data aggregator discovery (DAD) message may be distributed by an associated data aggregator, the DAD message identifying the initiating data aggregator, and comprising a recorded route taken from the data aggregator to a receiving particular node as well as a total path cost for the particular node to reach a root node of the DAG through the recorded route and via the data aggregator. The receiving particular node determines a path cost increase (PCI) associated with use of the data aggregator based on the total path cost as compared to a DAG-based path cost for the particular node to reach the root node via the DAG. If the PCI is below a configured threshold, the particular node may redirect traffic to the data aggregator as source-routed traffic according to the recorded route. The traffic may then be aggregated by the data aggregator, accordingly.

Abstract: A controller may be used to control client switches in a network that includes non-client switches. The controller may form client domains from groups of client switches that are separated by intervening non-client domains formed from non-client switches. The controller may determine a network domain topology from the client domains and non-client domains. The controller may determine a spanning tree that interconnects the nodes of the network domain topology. The controller may control client switches of the client domains to allow only network traffic between the client domains and the non-client domains along the spanning tree. The controller may use the network domain topology to generate inter-domain forwarding maps. The inter-domain forwarding maps may be used to determine network forwarding paths between end hosts in the network.

Abstract: In response to receiving one or more packets from an interface, an anchoring border router classifies the traffic flow and either transmits the packets based upon the routing control table as usual, or determines that the packets of the traffic flow are to be forwarded to a forwarding border router. Upon determining that the packets are to be forwarded, the packets are encapsulated with a routing encapsulation key corresponding to a routing path and are forwarded from the anchoring border router to the forwarding border router via a routing encapsulation tunnel. When a forwarding border router receives the redirected packets over the routing encapsulation tunnel, the forwarding border router removes the routing encapsulation key from the packets of the traffic flow and transmits the packets via a routing path corresponding to the routing encapsulation key.

Abstract: The present invention relates to a system and method for sharing and controlling various contents in a voice call. A contents sharing system includes a soft switch and a contents share server. The soft switch receives a voice call from a VoIP terminal to set establishment and cancellation on a voice call session, receives a contents sharing request call, and transmits the same to the contents share server. The contents share server in cooperation with the soft switch receives the contents request call and processes establishment and cancellation on a data session for contents sharing between the callers. Accordingly, improved calling is provided by sharing various contents between the callers in a voice calling and thereby overcoming the problem of communication only available for voice.

Abstract: In an ad-hoc wireless network, a single multicast message can be used to announce availability of queued data to one or more WLAN devices in the ad-hoc network. A wireless network device in the ad-hoc network can determine network identifiers associated with the other wireless network devices in the ad-hoc network for which the queued data is available. The wireless network device transmits the multicast message, which identifies the wireless network devices for which queued data is available, to indicate the wireless network devices that should remain in an active power state. On receiving the multicast message, a receiving WLAN device can read a network identifier bit associated with the receiving WLAN device to determine whether or not the receiving WLAN device should remain in the active power state. This can reduce transmission overhead and improve power savings, efficiency, and data reliability.

Abstract: An archival storage cluster of preferably symmetric nodes includes a data protection management system that periodically organizes the then-available nodes into one or more protection sets, with each set comprising a set of n nodes, where “n” refers to a configurable “data protection level” (DPL). At the time of its creation, a given protection set is closed in the sense that each then available node is a member of one, and only one, protection set. When an object is to be stored within the archive, the data protection management system stores the object in a given node of a given protection set and then constrains the distribution of copies of that object to other nodes within the given protection set. As a consequence, all DPL copies of an object are all stored within the same protection set, and only that protection set. This scheme significantly improves MTDL for the cluster as a whole, as the data can only be lost if multiple failures occur within nodes of a given protection set.

Abstract: A User Equipment, UE, of a cellular communication system transmits scheduling assistance data to a base station comprising a base station scheduler which schedules uplink packet data. The scheduling assistance data relates to uplink packet data transmission from the UE. The UE comprises a channel controller which is operable to cause the scheduling assistance data to be transmitted from the UE to the base station in a first physical resource of an uplink air interface. The first physical resource is not managed by the base station based scheduler. The scheduling assistance data may specifically be transmitted in a first transport channel multiplexed with other transport channels on a physical resource. The transport channels may be individually optimized and may have different termination points and transmission reliabilities. Specifically, the transport channel supporting the scheduling assistance data signaling may have a high reliability and be terminated in the base station.

Abstract: An efficient elastic enforcement layer (EEL) for realizing security policies is deployed in a cloud computing environment based on a split architecture framework. The split architecture network includes a controller coupled to switches. When the controller receives a packet originating from a source VM, it extracts an application identifier from the received packet that identifies an application running on the source VM. Based on the application identifier, the controller determines a chain of middlebox types. The controller further determines middlebox instances based on current availability of resources. The controller then adds a set of rules to the switches to cause the switches to forward the packet toward the destination VM via the middlebox instances.

A terminal determines a feedback cell where uplink transmission blocks and uplink control information are multiplexed, from among a plurality of serving cells. The terminal multiplexes the uplink transmission blocks and the uplink control information on an uplink shared channel of the feedback cell, and the multiplexed uplink control information is transmitted on the uplink shared channel of the feedback cell.

Abstract: Multiple field units in a CDMA system are synchronized for communication with a base station using a shared forward and reverse link channel. Each field unit is assigned a time slot in a forward link channel to receive messages from the base station. Likewise, each field unit is assigned a time slot on a common reverse link channel for transmitting messages to the base station. Timing alignment among each of many field units and the base station is achieved by analyzing messages received at the base station in a corresponding time slot from each field unit. Thereafter, a message is transmitted in a corresponding time slot to a particular field unit from the base station for adjusting its timing so that future messages transmitted from the field unit are received in the appropriate time slot at the base station.
