摘要： In one embodiment, a device in a network determines performance characteristics of a plurality of physical interfaces of the device. The device receives an application descriptive language-based description of performance requirements of a virtualized application for execution by the device. The device selects a particular one of the plurality of physical interfaces for use by the virtualized application during execution, based on the performance requirements of the virtualized application and on the performance characteristics of the plurality of physical interfaces. The device causes the virtualized application to use the selected physical interface during execution by the device.

摘要： A method is provided in one embodiment and includes establishing a primary wired access link between a first routing device and a second routing device, and establishing a backup wireless access link between the first routing device and the second routing device. The method further includes determining a status of the primary wired access link indicative of whether the primary wired access link between the first routing device and the second routing device has failed. The method still further include activating the backup wireless access link between the first routing device and the second routing device when it is determined that the status of the primary wired access link is indicative that the primary wired access link has failed.

摘要： A method is provided in one example embodiment and may include determining a predicted average throughput for each of one or more cellular interfaces and adjusting bandwidth for each of the one or more of the cellular interfaces based, at least in part, on the predicted average throughput determined for each of the one or more cellular interfaces. Another method can be provided, which may include determining a variance in path metrics for multiple cellular interfaces and updating a routing table for the cellular interfaces using the determined variance if there is a difference between the determined variance and a previous variance determined for the cellular interfaces. Another method can be provided, which may include monitoring watermark thresholds for a MAC buffer; generating an interrupt when a particular watermark threshold for the MAC buffer is reached; and adjusting enqueueing of uplink packets into the MAC buffer based on the interrupt.

摘要： Techniques for interface bandwidth management. A wired interface bandwidth is configured for a wired interface of a router. A cellular interface bandwidth is configured for a cellular interface of cellular interfaces of the router. The cellular interface bandwidth includes an uplink bandwidth. One or more instantaneous uplink throughput values for the cellular interface are determined based on one or more uplink throughput per resource block values for the cellular interface. A predicted average uplink throughput for the cellular interface is determined based on the one or more instantaneous uplink throughput values. The uplink bandwidth is dynamically adjusted based on the predicted average uplink throughput determined for the cellular interface of the router.
