A frangible fly through diaphragm for missile launcher tubes consists of epoxy and fiberglass plies with each ply being scored in predetermined patterns. The plies are bonded together and a Mylar/aluminum ply can be located on the missile side to provide gas sealing and electromagnetic interference protection. A segmented foam rubber outer layer can also be provided for additional protection from missile jet plumes.

Techniques are described for providing managed virtual computer networks that have a configured logical network topology with virtual networking devices, such as by a network-accessible configurable network service, with corresponding networking functionality provided for communications between multiple computing nodes of the virtual computer network by emulating functionality that would be provided by the virtual networking devices if they were physically present. In some situations, the networking functionality provided for a managed computer network of a client includes receiving routing communications directed to the virtual networking devices, and using included routing information to identify and initiate external actions whose effects are not related to how network communications between computing nodes of the managed computer network are configured to be routed or otherwise forwarded through the managed computer network, such as external actions that affect devices that are not part of the managed computer network, or other types of external actions.

Methods and apparatus for differential bandwidth metering in a network implementing direct peerings. A system includes a plurality of resource collections and a billing manager. The billing manager obtains a first metric of network traffic transmitted on behalf of a client to obtain one or more services from one or more resource collections. The billing manager also obtains a second metric of network traffic transmitted on behalf of the client over one or more private links, where each private link is set up to establish a network path between a respective client network of the client and a respective resource collection of the plurality of resource collections. The billing manager provides composite billing information to the client comprising a differential billing amount dependent upon a difference between the first metric and the second metric.
摘要:
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.
摘要:
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.

Techniques are described for providing managed virtual computer networks that may have a configured logical network topology with one or more virtual networking devices, with corresponding networking functionality provided for communications between multiple computing nodes of the virtual computer network by emulating functionality that would be provided by the networking devices if they were physically present. In some situations, the emulating of networking device functionality includes receiving routing communications directed to the networking devices and using included routing information to update the configured network topology for the managed computer network. In addition, the techniques may further include supporting interactions with devices that are external to the virtual computer network, including remote physical networking devices that are part of a remote computer network configured to interoperate with the virtual computer network, and/or specialized network devices that are accessible via a substrate network on which the virtual computer network is overlaid.
摘要:
Techniques are described for providing logical networking functionality for managed computer networks, such as for virtual computer networks provided on behalf of users or other entities. In some situations, a user may configure or otherwise specify a network topology for a virtual computer network, such as a logical network topology that separates multiple computing nodes of the virtual computer network into multiple logical sub-networks and/or that specifies one or more logical networking devices for the virtual computer network. After a network topology is specified for a virtual computer network, logical networking functionality corresponding to the network topology may be provided in various manners, such as without physically implementing the network topology for the virtual computer network. In some situations, the computing nodes may include virtual machine nodes hosted on one or more physical computing machines or systems, such as by or on behalf of one or more users.

Techniques are described for providing virtual networking functionality for managed computer networks. In some situations, a user may configure or otherwise specify a logical network topology for a managed computer network with multiple computing nodes that includes one or more virtual networking devices each associated with a specified group of the multiple computing nodes. Corresponding networking functionality may be provided for communications between the multiple computing nodes by emulating functionality that would be provided by the networking devices if they were physically present and configured to support the specified network topology. In some situations, the managed computer network is a virtual computer network overlaid on a substrate network, and the networking device functionality emulating includes receiving routing communications directed to the networking devices and using included routing information to update the specified network topology for the managed computer network.

Methods and apparatus for interfaces to manage last-mile connectivity and dynamic reconfiguration for direct network peerings. A system may include a data center, endpoint routers and a connectivity coordinator. The coordinator implements an interface defining connectivity operations. The coordinator receives a request for dedicated connectivity to data center resources, formatted according to the interface. The coordinator determines a connectivity provider to provide last-mile connectivity to the requester, and transmits a notification identifying the selected connectivity provider.
