First of all, in the project, I cannot use any transport protocol libraries, such as TCP. Therefore, I construct the packets and acknowledgements, and interpret the incoming packets by myself. A datagram is a basic transfer unit associated with a packet-switched network. Datagrams are typically structured in header and payload sections. Datagrams provide a connectionless communication service across a packet-switched network. The delivery, arrival time, and order of arrival of datagrams need not

As building and maintaining the infrastructure for compute, storage and networking resources from the ground up is becoming a serious capital constraint for small and medium businesses (SMBs) and enterprises, the era of cloud computing is becoming more and more established. This paper aims at understanding the open source OpenStack architecture and various services that it provides as Infrastructure as a Service (IaaS) to build scalable, cost-friendly and efficient cloud that relates to managing

The Growth and Development of Ideas on Race Without examining the past, our views today would be shallow and misleading. In making comparisons it is important to look at aspects of history to provide a more in depth understanding of certain social phenomenon. As comparisons are made, ideas emerge which can raise our levels of such understanding. In this way, by examining the meaning of race two hundred years ago, we can discover that the concept of ‘race’ has evolved;

Software from outside the devices takes over the job, instead of software embedded in the routers and switches managing the traffic. The network layout, or topography, is no longer rooted in the physical. Instead, it 's flexible and adjustable to the systems’ needs on the fly. SDN promises to solve both cost of labor performing manual maintenance and administrative

The power of Internet grows drastically when people, data and things are interconnected through the Internet. Internet of Things aka IoT, is a network of things or objects implanted with sensors and other smart electronic devices which enables them to communicate with each other and other targets in the network through exchange of data. These sensors generate a lot of data that needs to be stored, managed and analyzed. There are options to connect memory cards or computers to these sensors or we

The year is 1940 and the setting is the desperately poor, racially segregated town of Stamps, Arkansas. In the soft dirt beneath the stilts of her grandmother’s general store, she does not want anyone to hear her as she attempts a few lines of poetry. Maya Angelou has not spoken for five years since being raped at the age of seven, but slowly, tentatively, she begins to make a sound. Angelou did what not many can do – she defied stereotypes. She was a multifaceted character who was not defined by
