As the current generation of mobile smartphones become more powerful, they are being used to perform more resource intensive tasks making battery lifetime a major bottleneck. In this paper, we present a technique called dynamic AoV lookahead for reducing wireless interface power consumption upto 50% while playing a popular, yet resource intensive, mobile multiplayer games.

2020 Symposium on Networked Systems Design and Implementation  
Packet schedulers traditionally focus on the prioritized transmission of packets. Scheduling is often realized through coarse-grained queue-level priorities, as in today's switches, or through fine-grained packet-level priorities, as in recent proposals such as PIFO. Unfortunately, fixed packet priorities determined when a packet is received by the traffic manager are not sufficient to support a broad class of scheduling algorithms that require the priorities of packets to change as a function

In this paper, we revisit the Calendar Queue abstraction and show that it is an appropriate fit for scheduling algorithms that not only require prioritization but also perform dynamic escalation of packet priorities. We show that the calendar queue abstraction can be realized using either dataplane primitives or control-plane commands that dynamically modify the scheduling status of queues. Further, when paired with programmable switch pipelines, we can realize programmable calendar queues that can emulate a diverse set of scheduling policies. We demonstrate the power of this abstraction using three case studies that implement variants of LSTF, Fair Queueing, and pFabric in order to provide stronger delay guarantees, burst-friendly fairness, and starvation-free prioritization of short flows, respectively. We evaluate the benefits associated with these scheduling policies using both a custom simulator and a small-scale testbed.

For each pixel, we compute its brightness as a function of the pixel's Red (R), Blue (B), and Green (G) colour values. This is a common calculation, shown in Equation 3.7, used in image processing.  ...
