Abstract: A relay apparatus for data relay between multiple communication lines includes a sleep relay unit, a start-up determination unit and a communication block unit. The sleep relay unit relays a sleep instruction that instructs a designated apparatus to transition to a sleep mode. The start-up determination unit determines whether or not a start-up apparatus, which is an apparatus other than the designated apparatus and is in a normal mode, exists in a designated communication line, which is a communication line connected to the designated apparatus. Communication that uses the designated communication line is blocked by the communication block unit when it is determined that the start-up apparatus does not exist in the designated communication line.

Abstract: A method of dynamically allocating buffers involves receiving a packet onto an ingress circuit. The ingress circuit includes a memory that stores a free buffer list, and an allocated buffer list. Packet data of the packet is stored into a buffer. The buffer is associated with a buffer identification (ID). The buffer ID is moved from the free buffer list to the allocated buffer list once the packet data is stored in the buffer. The buffer ID is used to read the packet data from the buffer and into an egress circuit and is stored in a de-allocation buffer list in the egress circuit. A send buffer IDs command is received from a processor onto the egress circuit and instructs the egress circuit to send the buffer ID to the ingress circuit such that the buffer ID is pushed onto the free buffer list.

Abstract: Methods and apparatus to select a voice over Internet protocol (VoIP) border element are disclosed. An example method comprises sending a first session initiation protocol (SIP) protocol message from a first voice over Internet protocol (VoIP) device, the first SIP message comprising an Internet protocol (IP) address shared by at least two VoIP border elements, and receiving a second SIP message at the first VoIP device from a second VoIP device, the second SIP message comprising a unique address for the second VoIP device, the second VoIP device to be selected based on the shared IP address.

Abstract: Systems and techniques for processing and/or forwarding packets are described. An ingress switch can use a QoS mapping mechanism to map a first set of Quality of Service (QoS) bits in a packet received from a customer to a second set of QoS bits for use in a Transparent Interconnection of Lots of Links (TRILL) packet which encapsulates the packet. The first set of QoS bits can be different from the second set of QoS bits. The TRILL packet can be processed and/or forwarded in the network based on the second set of QoS bits. At the egress switch, the TRILL packet can be decapsulated and the original packet with the original QoS bits (or QoS bits that are different from the original QoS bits) can be forwarded to the customer's network. In this manner, some embodiments of the present invention can preserve the QoS bits across a TRILL network.

Abstract: A large-scale data center is based on orthogonal connectivity of a distributed single-stage connector, having a large number of disjoint primary switches, to a large number of access nodes and a large number of secondary switches. The secondary switches are coupled to a large number of servers forming a server farm. The orthogonal-connectivity scheme yields a contiguous network providing single-hop paths from each access node to each other access node, from each secondary switch to each other secondary switch, from each access node to each secondary switch, and from each secondary switch to each access node.

Abstract: A method and apparatus for dispatching messages in a distributed computing system. A dispatcher receives a message. The dispatcher examines the message to determine whether the message is addressed to the dispatcher. If the message is addressed to the dispatcher, the dispatcher performs an action based on the message. If the message is not addressed to the dispatcher, the dispatcher passes on the message to a destination.

Abstract: A method and score management node for supporting service evaluation by obtaining a perception score P reflecting a user's experience of a service delivered by means of a telecommunication network. The score management node receives network measurements related to service events when the service is delivered to the user. For each received network measurement, the score management node determines a quality score Q reflecting the user's perception of quality of service delivery by applying a first function on the network measurement, and determines an associated significance S reflecting the user's perception of importance of service delivery by applying a second function on the network measurement. The first and second functions are dependent on network measurement type. The perception score P is then calculated based on the determined quality scores Q and associated significances S, wherein the calculated perception score P is made available for use in the service evaluation.

Abstract: Embodiments disclosed herein provide individual idle-mode cell reselection priority lists to wireless devices dynamically, based on real-time load conditions for frequency bands deployed within a wireless network. Load equalization operations include classifying frequency bands into congested, target, or non-congested bands, grouping similar bands, comparing loads across the various bands in to a threshold, and adjusting the priority of each frequency band accordingly. The adjusted priorities are transmitted to each wireless device as the wireless device enters idle mode.

Abstract: In a wireless communication system, a client terminal may first establish time and frequency synchronization with the network. While establishing the time and frequency synchronization, a client terminal may need to detect additional parameters about the network, such as physical cell identity, before it can initiate communication with the wireless communication system. Detecting the network parameters in presence of time and frequency offsets increases the complexity of the initial cell search procedure that includes time and frequency synchronization as well as detection of network parameters. A method and apparatus are disclosed that achieve frequency synchronization earlier in the cell search procedure, which in turn reduces the complexity and improves the performance of the latter stages of cell search procedure and the overall performance of the client terminal.

Abstract: Techniques are described for supporting Fiber Channel over Ethernet (FCoE) link aggregation groups (LAGs) between a server and a data center switch in a data center. The techniques enable an access switch in the data center switch to assign class identifiers to each member link in an FCoE LAG between an FCoE node (Enode) of the server and the access switch. In this way, the access switch is able to redirect FCoE traffic from a Fiber Channel forwarder (FCF) of a storage area network (SAN) toward the Enode on the correct member link of the FCoE LAG. The techniques also enable scaling of FCoE initialization protocol (FIP) and FCoE sessions by installing FIP snooping filters that use on a source media access control (MAC) address hit determination in ingress filter processors (IFPs) of the access switch to avoid session limitations of virtual local area network (VLAN) filter processors (VFPs).
