OpenFlow is a novel technology designed at Stanford University which aims at decoupling the controller software from the forwarding hardware of a router or switch. The OpenFlow concept is based on the approach that the forwarding information base (FIB) of a switch can be programmed via a controller which resides at a separate hardware. The goal is to(More)
Software Defined Networking is a networking paradigm which allows network operators to manage networking elements using software running on an external server. This is accomplished by a split in the architecture between the forwarding element and the control element. Two technologies which allow this split for packet networks are For CES and Openflow. We(More)
Advancement in technology is very well reflected and supported by changes in measurement and control instrumentation. To move to high-speed serial from Parallel bus architectures has become prevalent and among these Ethernet is the most preferred switched Serial bus, which is forward-looking and backward-compatible. Great stride have been made in promoting(More)
In OpenFlow, control and data plane are decoupled from switches/routers. Direct programming of routers/switches is realised from one or more servers (so called controllers). In the case of an in-band OpenFlow network, the control traffic (traffic to or from the controllers) is sent on the same channel used to transport data traffic. Therefore, when a(More)
OBJECTIVE Although a dysfunctional prefrontal-striatal system is presupposed in obsessive-compulsive disorder (OCD), this is not unequivocally supported by neuropsychological studies. This study aims to study the neurocognitive dysfunctions in OCD patients, compared to controls; to study the variations in neurocognitive deficits with the duration of(More)
Software defined Networking (SDN) such as Open-Flow decouples the control plane from forwarding devices and embeds it into one or more external entities called controllers. We implemented a framework in OpenFlow through which business customers receive higher Quality of Service (QoS) than best-effort customers in all conditions (e.g. failure conditions). In(More)
OpenFlow decouples the control plane functionality from switches, and embeds it into one or more servers called controllers. One of the challenges of OpenFlow is to deploy a network where control and data traffic are transmitted on the same channel (in-band mode). Implementing such an in-band mode is complex, since switches have to search and establish a(More)
AIM Cognitive deficits have been presupposed to be endophenotypic markers in bipolar disorder, but few studies have ascertained the cognitive deficits in healthy relatives of bipolar disorder patients. The aim of the present study was to assess the cognitive functions of first-degree relatives of patients with bipolar disorder and compare them with healthy(More)
Optimized Link State Routing (OLSR) protocol is a table-driven proactive routing protocol for wireless mobile ad hoc networks. The key idea behind this protocol is to reduce the control message overheads by marking subset of neighbors as Multi-Point Relays (MPRs). In this paper, we discuss problems of OLSR or other routing protocols that are due to mobility(More)
