Disaggregation of both packet and optical networks is driving innovation in transport networks. We demonstrate a proof of concept and detail our plans for a field trial in a major service provider.
We propose a new approach to MPLS that uses the standard MPLS data plane and an OpenFlow based simpler and extensible control plane. We demonstrate this approach using a prototype system for MPLS Traffic Engineering.
We demonstrate a converged OpenFlow enabled packet-circuit network, where circuit flow properties (guarantee d bandwidth, low latency, low jitter, bandwidth-on-demand, fast recovery) provide differential treatment to dynamically aggregated packet flows for voice, video and web traffic.
There have been many attempts to unify the control and management of circuit and packet switched networks, but none have taken hold. In this paper we propose a simple way to unify both types of network using OpenFlow. The basic idea is that a simple flow abstraction fits well with both types of network, provides a common paradigm for control, and makes it easy to insert new functionality into the...
OpenFlow is proposed as an architectural platform and a unified control plane for packet and circuit networks, with the main goal of simplifying network control and management while fostering innovative change in them.
We evaluated a new simplified technique for secondary correction of persistent reflux in a reimplanted dilated ureter. Four patients a median of 3 years old with recurrent vesicoureteral reflux after initial reimplantation of ureters greater than 9 mm. in diameter underwent in situ excisional ureteral tailoring. Followup ranged from 15 to 27 months (mean 22). Within 3 months postoperatively...
This case is the first reported presentation of obstructive anuria due to extrinsic ureteral compression in a patient with dermatomyositis. Further evaluation revealed disseminated sigmoid colon adenocarcinoma. Conservative treatment of ureteral obstruction by internal double-J stents achieved appropriate palliation.
