Wide-area Software Defined Networking Experiments using Chameleon

Recent advancements have expanded Chameleon's support for networking experiments by enabling deeply programmable networks spanning wide-areas and controlled by the user. New capabilities include: 1) bring-your-own-controller (BYOC) software defined networking (SDN) and 2) Layer 2 stitching to external testbeds and facilities including stitching between the two Chameleon sites. This paper presents the new networking capabilities of Chameleon along with corresponding experiments that evaluate limitations and features of using SDN in a wide-area environment. The experiments serve both as an evaluation of SDN in a wide-area environment and as a guide for designing advanced networking experiments on Chameleon.
