  • Patent number: 9935816
    Abstract: A technology is described for updating an Autonomous System Number (ASN) in a Border Gateway Protocol (BGP) routing configuration. An example method may include receiving a request to update a BGP routing configuration on a gateway with an ASN associated with a customer. In response to the request, the BGP routing configuration on the gateway may be updated to replace a default ASN associated with a computing service provider with the ASN associated with the customer. The BGP routing configuration on the gateway may also be updated to allow the ASN associated with the customer to appear in an Autonomous System (AS) path at least twice, thereby allowing for BGP routes to be exchanged between gateways.

  • Patent number: 9712386
    Abstract: A connectivity manager (CM) of a provider network establishes a plurality of ERGs (edge resource groups), each comprising at least an edge router and a network marker translation agent (NMTA). The CM selects a particular ERG to be used for network traffic between a first set of resources of a virtual computing service of the provider network and a second set of resources outside the provider network. To enable connectivity between the first and second set of resources, the CM initiate propagation of (a) routing metadata to an edge router of the particular ERG and/or (b) a network marker mapping entry to an NMTA of the particular ERG.

  • Patent number: 9692729
    Abstract: A connectivity manager (CM) of a provider network selects, from a plurality of ERGs (edge resource groups), a particular ERG comprising an edge router and a network marker translation agent to be used for routing traffic between a resource collection of a VCS (virtual computing service) and a client network. The CM detects a condition that triggers the selection of a second ERG to be used for at least a subset of the resource collection's traffic, and initiates a set of configuration changes to enable the use of the second ERG for connectivity between the first resource collection and the client network.

  • Publication number: 20170150092
    Abstract: A pre-selectable video file playback system and method, and a computer program product are provided. Multiple first images are captured from multiple frame images in a first time interval, and two chronological first images thereafter are compared sequentially. A next first image is selected if the next first image is substantially different from a previous first image, and the next first image is not selected if the next first image is substantially the same as the previous first image. By displaying the selected first images, the number of images that users watch may be reduced.

  • Patent number: 9521053
    Abstract: A provider network may collect diagnostic metrics for virtual connections implemented over physical connections to resources in the provider network. Diagnostic metric collection may be enabled via an interface for the provider network. In response to receiving a request to enable diagnostic metric collection for a particular virtual connection, a diagnostic agent within the provider network may begin sending diagnostic request messages to a client-side endpoint via the particular virtual connection. Responses to the request messages may be received back at the diagnostic agent. The diagnostic responses may then be used to generate diagnostic metrics for the particular virtual connection, which may be provided through the provider network interface.
