Enterprise Networks, over the years, have become more and more complex tryingto keep up with new requirements that challenge traditional solutions. Just tomention one out of many possible examples, technologies such as Virtual LANs(VLANs) struggle to address the scalability and operational requirementsintroduced by Internet of Things (IoT) use cases. To keep up with thesechallenges we have identified four main requirements that are common acrossmodern enterprise networks: (i) scalable mobility, (ii) endpoint segmentation,(iii) simplified administration, and (iv) resource optimization. To addressthese challenges we designed SDA (Software Defined Access), a solution formodern enterprise networks that leverages Software-Defined Networking (SDN) andother state of the art techniques. In this paper we present the design,implementation and evaluation of SDA. Specifically, SDA: (i) leverages acombination of an overlay approach with an event-driven protocol (LISP) todynamically adapt to traffic and mobility patterns while preserving resources,and (ii) enforces dynamic endpoint groups for scalable segmentation with lowoperational burden. We present our experience with deploying SDA in tworeal-life scenarios: an enterprise campus, and a large warehouse with mobilerobots. Our evaluation shows that SDA, when compared with traditionalenterprise networks, can (i) reduce overall data plane forwarding state up to70% thanks to a reactive protocol using a centralized routing server, and (ii)reduce by an order of magnitude the handover delays in scenarios of massivemobility with respect to other approaches. Finally, we discuss lessons learnedwhile deploying and operating SDA, and possible optimizations regarding the useof an event-driven protocol and group-based segmentation.
