In Software Defined Networking (SDN) the control plane is physically separate from the forwarding plane. Control software programs the forwarding plane (e.g., switches and routers) using an open interface, such as OpenFlow. This paper aims to overcomes two limitations in current switching chips and the OpenFlow protocol: i) current hardware switches are(More)
P4 is a high-level language for programming protocol-independent packet processors. P4 works in conjunction with SDN control protocols like OpenFlow. In its current form, OpenFlow explicitly specifies protocol headers on which it operates. This set has grown from 12 to 41 fields in a few years, increasing the complexity of the specification while still not(More)
In this paper, we present the Tiny Tera: a small packet switch with an aggregate bandwidth of 320Gb/s. The Tiny Tera is a CMOS-based input-queued, fixed-size packet switch suitable for a wide range of applications such as a highperformance ATM switch, the core of an Internet router or as a fast multiprocessor interconnect. Using off-the-shelf technology, we(More)

We report the remarkable surface behavior of class II hydrophobin proteins HFBI and HFBII from Trichoderma reesei and the resulting effect that these proteins have on the stability of air bubbles to the process of disproportionation. The surface properties were studied using surface tensiometry and surface shear rheology. Surface tensiometry data show that(More)
We consider two spherical, roughened crystals with approximately isotropic surface free energy, which are brought into contact and begin to sinter. We argue that the geometry immediately postcontact is two dimensional and Cartesian and can be approximated by the evolution of a slot-shaped cavity. On this basis, we construct traveling wave solutions for the(More)

Software defined network has been the buzzword among networking professionals since the last few years. SDN promises to simplify network management using its three tiered architecture. Unfortunately, a significant amount of research that is going on in this field is focused on huge enterprise or datacenter networks. The social impact that this technology(More)
