Software-Defined Networking (SDN) refers to a new approach for network programmability, that is, the capacity to initialize, control, change, and manage network behavior dynamically via open interfaces. SDN emphasizes the role of software in running networks through the introduction of an abstraction for the data forwarding plane and, by doing so, separates it from the control plane. This separ...

The Internet has evolved immensely since its inception to being a network of academic and government institutions to its present magnanimous commercial avatar. It is currently deemed to be the single largest resource for information and services. From the times it was managed by central authorities, first by DARPA and then by NSF, the present internet has matured to become a commercially driven...

In Feb. 2007, we presented a proposal to test applications and the CHEETAH control-plane solution on the HOPI testbed. We also proposed to implement a software program called a “Force-10 virtualizer,” which would allow multiple control-plane and/or management-plane modules to simultaneously control the data-plane resources of the Force10 switches. The reader is referred to [1] for further details.

Many researchers have controlled and analyzed biped robots that walk in the sagittal plane. Nevertheless, walking robots require the capability to walk merely laterally, when they are faced with the obstacles such as a wall. In walking robot field, both nonlinearity of the dynamic equations and also having a tracking system cause an effective control has to be utilized to address these problems...

Bionic underwater robots have many advantages such as high mobility, efficiency, affinity, etc. They are especially suitable for tasks collecting hydrographic information and detailed surveys of the marine environment. These based on their high-precision attitude control. Therefore, this paper proposes a control scheme bionic robot—a manta robot. To improve depth retention capability robot, S-p...
