Abstract: Techniques for loop prevention while allowing multipath in a virtual L2 network are described. In an example, a network virtualization device can generate a first L2 bridge protocol data unit by applying a first loop detection protocol specific to only the first port and the first host machine. The network virtualization device can transmit, to the first compute instance via the first port, a first frame that includes the first L2 BPDU. The network virtualization device can receive, from the first compute instance via the first port, a second frame. The network virtualization device can determine that the second frame comprises the first L2 BPDU. The network virtualization device can determine that a loop exists between the network virtualization device and the first compute instance based on the first loop detection protocol and the first L2 BPDU of the second frame.

Abstract: Techniques for loop prevention while allowing multipath in a virtual Layer 2 (L2) network are described. In an example, a network interface card (NIC) supports the virtual L2 network. The NIC is configured to receive, via a first port of the NIC, an L2 frame that includes a source media access control (MAC) address and a destination MAC address. Based on a loop prevention rule, the NIC transmits the L2 frame via its ports except the first port. In an additional example, the NIC is further configured to send an L2 frame to a host via the first port of the NIC. The L2 frame can be a bridge protocol data unit (BPDU). Upon receiving a BPDU from the host via the first port, the NIC determines that the BPDU is looped back and disables the first port.

Abstract: A Network Virtualization Device (NVD) executes a set of Virtual Network Interface Cards (VNICs). The set of VNICs includes a first VNIC that forwards packets for a set of one or more packet flows. The NVD stores a first VNIC-related information that includes information identifying a first set of one or more packet flows and associated state information The NVD in response to determining that the state information for the first VNIC is to be synchronized with another NVD, identifies a first backup NVD for the first VNIC, wherein the first backup NVD is a backup for the first VNIC, and communicates to the first backup NVD, a portion of the state information stored by the NVD for the first VNIC.

Abstract: Systems and methods for support server high availability with network link bonding for cloud overlay networks are disclosed herein. The method can include selecting a compute instance, identifying a plurality of Network Virtualization Devices (“NVD”) for association with the compute instance, and creating a number of Virtualized Network Interface Cards (“VNIC”), each of which VNICs can reside in one of the plurality of NVDs. The method can include overlaying an IP address of the compute instance to each of the VNICs, such that each of the VNICs share a common IP address, designating a network path formed by one of the VNICs in one of the NVDs as an active network path and another of the network paths as an inactive network path, and activating the inactive network path when the active network path fails.

Abstract: In an example embodiment, there is disclosed herein a network service that automatically adjusts content sent to a subscriber to optimize the subscriber's browsing and/or rich media experience within a quota set by the subscriber's service plan. The quality of audio and/or video streamed to a subscriber can be adjusted (for example by compressing, and/or changing the size, color, depth of images, and/or removing images from a stream) based on consumption data and the subscriber's remaining allowance. For example, the quality of an audio and/or video stream may be reduced if the subscriber is exceeding their quota, or the quality of the video and/or audio stream may be increased if the subscriber has sufficient bandwidth remaining for a predetermined time period.

Abstract: A bridging server instantiates virtual packet telephones that emulate physical packet telephone instruments, and includes a switch operative to establish connections between respective pairs of the virtual packet telephones. A first one of a pair of virtual packet telephones is operative to receive an incoming packet telephone call on behalf of a circuit telephone for which an incoming packet telephone call is destined. A controller in the bridging server establishes, via a gateway device, a first connection between the circuit telephone and a second one of the pair of virtual packet telephones, and in response to the incoming packet telephone call establishes control inputs of the switch to establish an internal bridging connection between the first and second virtual packet telephones, thus completing the end-to-end connection. From the perspective of other packet telephony equipment, the bridging server effectively hides the connection to the circuit telephone.

Abstract: Methods and systems for collecting log data from one or more components distributed in a network are described. In one example, a method may include providing a server with a persistent storage device such as a disk drive and the server may be in communication with the one or more components in the network. Log data may be collected at the components and an error from a first component may be reported to the server. In response thereto, log data related to the error may be requested from other components and communicated to the server. The components may each maintain log data locally and either report the occurrence of errors that occur at the component or component's node, or respond to requests from the server for data related to errors or events that occurred at other nodes. Accordingly, the server may maintain a real-time collection of error log data.
