  • Patent number: 9467897
    Abstract: The present invention provides a method and system for managing temporary block flow in a data communication network environment. In one embodiment, a temporary block flow is established between the first entity and the second entity. Then, it is determined whether the established TBF is to be maintained for a predetermined time period by the first entity based on quality of service (QoS) parameters associated with the established TBF. Further, a message indicating that the established TBF is to be maintained for the predetermined time period is sent to the second entity if the established TBF is to be maintained. Also, the established TBF between the first entity and the second entity is extended in uplink or delayed in downlink. If the established TBF is not to be maintained, the TBF established between the first entity and the second entity is teared down.

  • Patent number: 9461915
    Abstract: The present technology considers network devices that include forwarding tables having a number of next-hop entries (e.g., egress ports) where it is possible that the egress port utilization can be load balanced using WCMP groups. To implement a WCMP group, its members are assigned weights representing an amount of data flow to distribute over a plurality of links for a given destination. The members may be replicated in a forwarding table proportionally to their assigned weights. This disclosure provides systems and methods to reduce the number of forwarding table entries required when implementing a WCMP group.

  • Patent number: 9385970
    Abstract: Achieving resource management within a network processing unit (NPU) can be challenging due to the NPU's fixed and limited instruction set. In the case of large mobile networks, contexts are dynamic, and each subscriber in the network consumes multiple hardware resources, where a central processing unit (CPU) is typically employed to program individual resources even though generally impractical in high-session rates. To avoid programming individual resources, an example embodiment of the present invention creates a group of resources depending on a category, the group being shared dynamically among subscribers when a subscriber is active in the network. The example embodiment may include a network service processor (NSP) located in a forwarding path, such that the NPU may operate in connection with the NSP to allocate NPU resources using a packetized interface. The example embodiment achieves resource management within the NPU without a host CPU's involvement and without statically delaying resources.

  • Patent number: 9344463
    Abstract: A method and apparatus for service control in which a service centralization and continuity application server (SCC AS): receives a first SIP message for establishing an IMS centralized service session; receives early session media information; and sends a second SIP message carrying the early session media information to a media gateway control device. The early session media information is carried in the second SIP message in a form of regular session media information, thus the media gateway control device uses an existing circuit switched bearer to transmit early session media to a first user equipment. The existing circuit switched bearer is established under control of the media gateway control device for a session between the first user equipment and a third user equipment. The SCC AS receives an off-hook signal from the second user equipment, and sends the regular session media information to the media gateway control device.
