Abstract: Methods and apparatus for coordinating inter-region operations in provider networks. An inter-region coordinator (IRC) operates asynchronously to the control planes of regional networks to coordinate inter-region operations. The IRC in a region may include one or more IRC servers. To perform inter-region operations, the servers may implement a local-remote-local method in which a server invokes an API in the local region to get work, sends the work to a control plane of a remote region, receives a response from the remote region, and informs the control plane in the local region of the status of the work.

Abstract: Systems, methods, and computer-readable storage media are provided for managing status of state machines in a computing network. Various embodiments of the present technology can be used to track and maintain an active log associated with each state machine in a computing network. The active log of a state machine can be periodically analyzed at a predetermined time interval to determine an anticipated state of the state machine and a current state of the state machine. In response to determining that the state machine is in an inconsistent state (i.e., the anticipated state does not match the current state of the state machine), a suitable action can be taken to switch the current state of the state machine from the inconsistent state to a suitable new state.

A new reference architecture may be implemented by specifying a new service rendering program function for the new reference architecture.

Abstract: A link detection technology. In a link detection method, when a target event occurs on paths, in a plurality of paths, whose quantity exceeds a preset quantity, whether the paths on which the target event occurs share a bottleneck link is detected, and congestion control is performed. It can be learned that in the technical solution provided in the embodiments of this application, the target event is a trigger, and shared bottleneck detection is performed after the quantity of the paths on which the target event occurs exceeds the preset quantity. This implements purposeful link detection, reduces system overheads, and brings a fast convergence speed.

Abstract: Techniques for scalable virtualization of an Input/Output (I/O) device are described. An electronic device composes a virtual device comprising one or more assignable interface (AI) instances of a plurality of AI instances of a hosting function exposed by the I/O device. The electronic device emulates device resources of the I/O device via the virtual device. The electronic device intercepts a request from the guest pertaining to the virtual device, and determines whether the request from the guest is a fast-path operation to be passed directly to one of the one or more AI instances of the I/O device or a slow-path operation that is to be at least partially serviced via software executed by the electronic device. For a slow-path operation, the electronic device services the request at least partially via the software executed by the electronic device.

In one embodiment, an L2 concentrator appliance, which bridges a local area network (LAN) and a wide area network (WAN) in a stretched network, is configured such that multiple Internet Protocol Security (IPsec) tunnels are pinned to respective CPUs or cores, which each process traffic flows for one of the IPsec tunnels. Such parallelism can increase the throughput of the stretched network. Further, an L2 concentrator appliance that receives FOU packets is configured to distribute the received FOU packets across receive queues based a deeper inspection of inner headers of such packets.

Abstract: A method, system and computer program product for managed object replication and delivery redirects, directly or indirectly, a client's request for an object that is not available at a best or optimal handling edge server of a network to a parent server that has the requested object. So, where the requested object is not available at the handling edge server, the client's request is redirected directly to the parent server that can provide the requested object to the client or indirectly via one or more parent servers to a parent server that can provide the requested object to the client. The method, system and computer program product further intelligently replicates the object to the edge server if the object is popular enough. Likewise, an object is removed from an edge server when it is no longer popular. All redirection and replication operations are preferably transparent to the end-user and do not degrade the quality of service.

Abstract: A system and method for transmitting data from a local management system of a remote office branch office site in a virtual computing system to a central management system includes assigning, by the local management system, an initial priority to each piece of data, identifying data requested by the central management system since a previous data transmission, and updating the initial priority of each piece of data to an updated priority. The data requested by the central management system is prioritized higher than other data. The system and method also include combining, by the local management system, at least a portion of the data starting with data having a highest priority, into a data packet until the data packet achieves a computed data packet size, transmitting the data packet to the central management system, and updating the initial priority with the updated priority for future data transmissions.

Abstract: Embodiments of the present invention can use a protocol-independent, vendor-independent, efficient and scalable abstraction model for representing the forwarding functionality of networks. Such a model can be used for systematic analysis and verification of networks. Packet header values may be represented as groups of one or more wildcarded bit strings, where unspecified header values are assumed to be fully wildcarded. This representation can describe many combinations of packets in a space-efficient way, enables more efficient tracing and transformation operations, and can even represent traffic from large internet routing tables efficiently. As a result of the scalability benefits of this more effective way to store and operate on packet collections, network modeling can scale to some of the largest, most complicated networks—those where the benefits are the greatest.
