Abstract—OpenFlow is an open standard that can be implemented in Ethernet switches, routers and wireless access points (AP). In the OpenFlow framework, packet forwarding (data plane) and routing decisions (control plane) run on different devices. OpenFlow switches are in charge of packet forwarding

Abstract. Recent efforts in software-defined networks, such as OpenFlow, give unprecedented access into the forwarding plane of networking equipment. When building a network based on OpenFlow however, one must take into account the performance characteristics of particular OpenFlow switch

Today’s mobile network presents an oxymoron. While innovative services are sought after by ISPs, deployment of novel services by small businesses and researchers are often met with great resistance. This stems from the coupling of infrastructure and service providers, preventing multiple services to coexist in a single infrastructure. To explore for a remedy to this, we design, build and deployed a wireless network in which multiple services can coexist within a single infrastructure. In this work, we share our design and experience gained. Alice’s

-bypacket details, while packet-processing exposes those details, providing “micro”-level control. Currently, due to architectural or hardware constraints, network protocols must typically use one paradigm or the other. We will present an OpenFlow element for Click, which allows hybrid packet and flow processing

We describe the implementation of an OpenFlow Switch on the NetFPGA platform. OpenFlow is a way to deploy experimental or new protocols in networks that carry production traffic. An OpenFlow network consists of simple flow-based switches in the datapath, with a remote controller to manage several

and switch vendors, leaving OpenFlow vulnerable to manin-the-middle attacks. We also highlight the classes of vulnerabilities that emerge from the separation of the control plane and data planes in OpenFlow network designs. We illustrate that, due to the centralized design of the network, special care must

Today’s data centers host online services on multiple servers, with a front-end load balancer directing each client request to a particular replica. Dedicated load balancers are expensive and quickly become a single point of failure and congestion. The OpenFlow standard enables an alternative
