Software-Defined Networking (SDN): Unleashing the Power of the NetworkRobert Keahey
It goes without saying that cloud computing has dramatically reshaped the information technology services landscape. Virtualization is unleashing the power of commodity-based technology and open source communities are building new applications and services at an astonishing rate, but networking has lagged behind compute and storage in virtualization and automation. We’ve become accustomed to specialized networking silicon, complex operating systems and highly distributed control planes. For the most part, we’ve accepted the model along with its high costs.
All that is changing! New protocols such as OpenFlow are freeing the network control plane from proprietary operating systems and hardware platforms. We are entering a new era where customers control the features – and release schedules – of new, open networking applications that address the needs of the mega-scale world.
A lot of work is required to realize the potential of Software-Defined Networking (SDN), where we can enjoy the benefits derived from “software automating software.” This talk will examine some of the history that led us to the point where current networking architectures are no longer viable for cloud computing at mega-scale. We’ll take a look at the basics of SDN and some of its key elements – OpenFlow, network virtualization, and orchestration – along with some of the initiatives and companies that are setting the stage for the next generation of networking.

Understanding and deploying Network VirtualizationSDN Hub
Analogous to server virtualization, Network Virtualization decouples and isolates virtual networks (i.e. tenant) from the underlying network hardware. One of the key value propositions of Software-Defined Networking (SDN) is to enable the provisioning and operation of virtual networks. This tutorial motivates the need for network virtualization, describes the high-level requirements, provides an overview of all architectural approaches, and gives you a clear picture of the vendor landscape.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
