Abstract: Techniques are described for providing managed computer networks, such as for managed virtual computer networks overlaid on one or more other underlying computer networks. In some situations, the techniques include facilitating replication of a primary computing node that is actively participating in a managed computer network, such as by maintaining one or more other computing nodes in the managed computer network as replicas, and using such replica computing nodes in various manners. For example, a particular managed virtual computer network may span multiple broadcast domains of an underlying computer network, and a particular primary computing node and a corresponding remote replica computing node of the managed virtual computer network may be implemented in distinct broadcast domains of the underlying computer network, with the replica computing node being used to transparently replace the primary computing node in the virtual computer network if the primary computing node becomes unavailable.

Abstract: Methods and apparatus for dynamic bandwidth management using routing signals in a network implementing direct peerings. A system includes a resource collection, an endpoint device connected to a private link of a network path to a client network, and a bandwidth manager. The bandwidth manager receives configuration settings of the client, comprising a baseline transmission rate of traffic. The bandwidth manager determines whether a difference between a measured transmission rate of traffic over one or more network paths linking the resource collection and the client network, and a peak transmission capacity of the one or more network paths, exceeds a threshold value. In response to a determination that the difference exceeds the threshold value, the bandwidth manager initiates a transmission of a routing signal to the client network indicative of an available transmission rate that differs from the baseline transmission rate.

Abstract: Systems and methods involve receiving a connectivity subscription request for one or more connections, such as a virtual private network (VPN) connection. A connectivity subscription request may be received through an application programming interface (API) call and the connectivity subscription request may indicate that a user associated with a connection wants to receive a notification when a connectivity event occurs. A connectivity event can occur when changes to the connection are detected, such as when the connection becomes active, when the connection becomes inactive, or when one or more tunnel connections related to the connection becomes disconnected. A potential problem associated with the connectivity event may be detected and a potential solution to the problem may be determined. The potential solution can be sent to a user associated with the connectivity event.

Abstract: Methods and apparatus for bandwidth metering in large-scale networks are disclosed. Metadata for a network transmission involving a virtualized resource at a host of a provider network, including endpoint address information and a traffic metric, is determined at a metering component. The metadata is aggregated at another metering component and provided to a traffic classification node. The traffic classification node generates a categorized usage record for the network transmission, based at least in part on network topology information associated with the provider network. The categorized usage record is used to determine a billing amount for the network transmission.

Abstract: Systems and methods for end-to-end network-based services metering validation in a network-based services system may support configuring a client usage simulator on one or more computers to simulate client usage of a network-based services system. The system and method may include implementing an external usage meter in the client usage simulator to monitor and record one or more types of usage and send the information to an auditor implemented on one or more computers. An internal meter in the network-based services system may monitor and record usage of the network-based services system by the client usage simulator. The recorded information may be sent to an auditor for comparison with the external records.

Abstract: Methods and apparatus for interfaces to manage direct network peerings. A system may include a data center, endpoint routers and a connectivity coordinator. The coordinator implements a programmatic interface defining connectivity operations. The coordinator receives a request for dedicated connectivity to data center resources, formatted according to the interface. The coordinator selects a target endpoint router at which to establish a physical link to implement the dedicated connectivity, and transmits a response identifying the target endpoint router and including configuration instructions for setting up a physical link for the dedicated connectivity.

Abstract: A fiber optic connection system includes a fiber optic switching device, a first optical fiber holder, and a second optical fiber holder. The fiber optic switching device includes optical waveguides and an optical waveguide carrier that carries the optical waveguides. The first optical fiber holder holds a first set of optical fibers at a first location relative to the optical waveguide carrier. A second optical fiber holder holds a second set of optical fibers at a second location relative to the optical waveguide carrier. The optical waveguide carrier is movable to position the one or more optical waveguides such that the optical waveguides optically couple the optical fibers in the first set of optical fibers to optical fibers in the second set of optical fibers.

Abstract: Techniques are described for providing a managed computer network, such as for a managed virtual computer network overlaid on another substrate computer network, and including managing communications for computing nodes of the managed computer network by using one or more particular hardware devices connected to the substrate computer network to operate as a logical network node of the managed computer network that acts as an intermediate destination to provide one or more types of functionality for at least some communications that are sent by and/or directed to one or more computing nodes of the managed computer network. For example, a communication manager module associated with a source computing node for the managed computer network may determine to direct a communication from the source computing node over the substrate network to one or more substrate hardware devices that represent a particular intermediate destination network node of the managed computer network.

Abstract: Techniques are described for providing managed computer networks. In some situations, the techniques include managing communications for computing nodes of a managed computer network by using one or more particular computing nodes of the managed computer network that are configured to operate as intermediate destinations to handle at least some communications that are sent by and/or directed to one or more other computing nodes of the managed computer network. For example, a manager module associated with a source computing node may select one or more particular intermediate destination computing nodes to use for one or more particular communications from the source computing node to an indicated final destination, such as based on a configured logical network topology for the managed computer network. The manager module then forwards those communications to a first of the selected intermediate destination computing nodes for further handling.

Abstract: Various electronic resources, such as multi-tenant or cloud resources, can be pooled together for access by specified members associated with a given pool. For example, users with access to different resources can enable their resources to be pooled together for purposes such as reduced pricing and increased flexibility. In some instances, a user can pool resources configured for a particular purpose, such that the user can effectively lease out an entire environment. The users accessing the pool can pay for some or all portion of the cost of the resources during the period of usage.

Abstract: Methods and apparatus for interfaces to manage service marketplaces accessible via direct network peerings. A system may include a plurality of resource collections and a connectivity coordinator. The coordinator implements a programmatic interface defining connectivity operations. A first client may implement a service using one of the resource collections.

In response to a subscription request for the service, the coordinator performs one or more configuration operations to enable a request for the service from the second client to be routed using the second client's dedicated physical link.
