Problems solved by technology

Since traffic routing is often time critical, delayed flows on cellular interfaces can lead to system congestion, lost packets, and / or overloaded router resources, etc.
Therefore, there are significant challenges in managing the cellular interface of routing devices in a network environment

Abstract

A method for managing cellular interfaces for routing equipment in a network environment is provided that includes determining a predicted average throughput for each of one or more cellular interfacesof a router 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 is provided which includes 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 is provided which includes monitoring watermark thresholds for a MAC buffer of a cellular interface; 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.
