  • Patent number: 9584407
    Abstract: Systems and techniques are described for a path maximum transmission unit (MTU) discovery method that allows the sender of IP packets to discover the MTU of packets that it is sending over a conduit to a given destination. The MTU is the largest packet that can be sent through the network along a path without requiring fragmentation. The path MTU discovery method actively probes each sending path of each conduit with fragmentation enabled to determine a current MTU and accordingly increase or decrease the conduit MTU. The path MTU discovery process is resilient to errors and supports retransmission if packets are lost in the discovery process. The path MTU discovery process is dynamically adjusted at a periodic rate to adjust to varying network conditions.

  • Patent number: 9585051
    Abstract: A new deployment model enables a seamless migration to LTE (long term evolution)/EPC (Evolved packet core). In addition, an intelligent edge gateway (IEG) supports future distributed architecture and a converged network for service providers. Specifically, the model supports existing data services (e.g. UMTS) and the delivery of LTE services does not affect the existing data services. Moreover, a distributed architecture is employed, such that, local traffic is optimally routed at the edge and backhaul is minimized. The system can also provide support for enhanced Femto cell 3GPP access to a home network.

At a video conference bridge device configured to send and receive communications to an endpoint device in a network, one or more video streams are received from the endpoint participating in a video conference. Each of the video streams is classified as a rate adaptive stream or as a non-rate adaptive stream. For video streams classified as rate adaptive streams, the video streams are assigned to a buffer queue for rate adaptive streams. For video streams classified as non-rate adaptive streams, the video streams are assigned to a buffer queue for non-rate adaptive streams.

  • Patent number: 9571426
    Abstract: Some embodiments provide a queue management system that efficiently and dynamically manages multiple queues that process traffic to and from multiple virtual machines (VMs) executing on a host. This system manages the queues by (1) breaking up the queues into different priority pools with the higher priority pools reserved for particular types of traffic or VM (e.g., traffic for VMs that need low latency), (2) dynamically adjusting the number of queues in each pool (i.e., dynamically adjusting the size of the pools), (3) dynamically reassigning a VM to a new queue based on one or more optimization criteria (e.g., criteria relating to the underutilization or overutilization of the queue).
