  • Patent number: 9860112
    Abstract: A technique for synchronizing operations in a transaction processing system includes identifying, by a first recovery management connector (FRMC) in a first region, a failure of a first network connection having a first network type during synchronization operations with a partner region. The FRMC queries connections defined to the transaction processing system to identify a replacement network connection that is connected to the partner region using a second network type that is different than the first network type. The FRMC collects relevant data for an interrupted synchronization operation. The FRMC issues a command to link to a specific program in a FRMC in the partner region. The command includes the relevant data for the interrupted synchronization operation. A second recovery management connector of the first region communicates the command to and a response from the partner region via the replacement network connection in order to continue the interrupted synchronization operation.

  • Patent number: 9838948
    Abstract: Methods and systems are described for intelligently steering client devices operating in an enterprise network system to an appropriate access point based on types of traffic on each client device and/or types of traffic on access points. In particular, client devices may be moved to a different access point when the wireless channel provided by a current access point fails to meet the signal strength requirements of latency sensitive traffic utilized by the client device. Client devices may be further steered to new access points based on load conditions on access points. For example, client devices with low priority traffic sessions may be steered away from access points with high traffic load levels. Accordingly, the methods and systems described herein ensure improved network access for latency sensitive access categories and/or access categories that are considered important to an enterprise system with minimal disruptions to these sessions.

  • Patent number: 9825724
    Abstract: According to some embodiments, a master device sends synchronization packets to one or more slave devices, and does so periodically based on a master clock signal having a master clock frequency. At each of the slave devices, an algorithm estimates the master clock frequency based on the timing of synchronization packet arrivals the slave device. The algorithm may estimate the master clock frequency using both the currently-observed timing of synchronization packet arrivals and the history of previous synchronization packet arrivals (e.g., previously-observed timing of synchronization packet arrivals). Based on the estimated master clock frequency, each of the one or more slave devices can update the frequency of their respective slave clock signal (e.g., using a frequency offset) to match that of the estimated master clock frequency.

  • Patent number: 9819573
    Abstract: Various techniques for partitioning a computer network is disclosed herein. In certain embodiments, control plane functions (e.g., computation of network routes) and/or forwarding plane functions (e.g., routing, forwarding, switching) may be partitioned and performed individually on per domain basis based on (1) a network configuration of a particular domain (e.g., end points and/or lower-level domains in the particular domain); and (2) one or more higher-level domains connected to the particular domain in the hierarchy. Thus, a particular domain can manage various network operations of the domain without concerns regarding end points or network nodes in other domains of the hierarchy. Thus, network configuration and operation may be partitioned to reduce hardware costs and operational complexity even as the size of the overall computer networks increases.

  • Patent number: 9807017
    Abstract: One embodiment of the present invention provides a switch. The switch comprises one or more ports, a link management module and a load balancing module. The link management module operates a port of the one or more ports of the switch in conjunction with a remote switch to form a virtual link aggregation. The load balancing module generates an index of a weight distribution vector based on address information of a multicast group associated with the virtual link aggregation. A slot of the weight distribution vector corresponds to a respective switch participating in the virtual link aggregation. In response to the index indicating a slot corresponding to the switch, the load balancing module designates the switch as primary switch for the multicast group, which is responsible for forwarding multicast data of the multicast group via the virtual link aggregation.

  • Patent number: 9794831
    Abstract: The present invention provides a method for shortening signaling delay of ISC session transfer procedure, a network element for controlling ISC session transfer, a network element for anchoring a media path in ISC session transfer and a communication system including at least two terminals and the above two network elements. In the present invention, the SCC AS decides if a media path needs to be anchored in a media anchor point MRF, and if yes, then instructs a MRF to assign respective media endpoints for a local UE and a remote UE and connect the two media endpoints together, so as to divide the session between the local UE and the remote UE into two independent sub-sessions: a session between the local UE and the MRF, and a session between the remote UE and the MRF. For these two sub-sessions, the SIP signaling is terminated and sent out in the SCC AS. Thus, when a local UE or a remote UE triggers handover, only one sub-session needs to be updated/influenced.
