Visualization of Dynamic Resource Allocation for HEVC Encoding in FPGA-Accelerated SDN Cloud

Abstract

This paper describes a demonstration setup to visualize dynamic resource allocation for real-time HEVC encoding services in FPGA-accelerated cloud. The demonstrated application is Kvazaar HEVC intra encoder, whose functionality is partitioned between FPGAs and processors. During the demonstration, several encoding services can be invoked with requests to the resource manager, which is responsible for allocation, deallocation, and load balancing of resources in the network. The manager provides JSON data to the visualizer, which uses D3 JavaScript library to visualize 1) the physical network structure; 2) running services; and 3) performance of the network elements. This interactive demonstration allows users to request new video streams, view the encoded streams, observe the visualization of the network and services, and manually turn on/off resources to test the robustness of the system.
