We explore the design of a logically centralized but physically distributed control plane for 4D architecture. 4D architecture proposes centralization of network-wide decision making state and logic in a logical control plane to ease the management complexity of data networks. However, the current design implementations of the 4D control plane are limited(More)
We provide a design of a control and management plane for data networks using the abstraction of 4D architecture, utilizing and extending 4D’s concept of a logically centralized Decision plane that is responsible for managing network-wide resources. In this paper, a scalable protocol and a dynamically adaptable algorithm for assigning Data plane devices to(More)
We investigate the design of a clean-slate control and management plane for data networks using the abstraction of 4D architecture, utilizing and extending 4D’s concept of logically centralized Decision plane that is responsible for managing network-wide resources. In this paper, a dynamically adaptable algorithm for assigning Data plane devices to a(More)
Our research provides a framework for the design of clean-slate network control and management plane using the abstraction of 4D architecture. We utilize and extend 4D’s concept of a logically centralized Decision plane that is responsible for managing network-wide resources, and present mechanisms for network operators to centrally plan, control, and(More)
We study link scheduling in networks with small router buffers, with the goal of minimizing the guaranteed packet loss rate bound for each ingress-egress traffic aggregate (connection). Given a link scheduling algorithm (a service discipline and a packet drop policy), the guaranteed loss rate for a connection is the loss rate under worst-case routing and(More)
Advances in nanotechnology, large scale computing and communications infrastructure, coupled with recent progress in big data analytics, have enabled linking several billion devices to the Internet. These devices provide unprecedented automation, cognitive capabilities, and situational awareness. This new ecosystem--termed as the Internet-of-Things(More)
