Internet Design

INTRODUCTION The concept of the internet started over 50 years ago when computers filled the entire room, today it is an ubiquitous information infrastructure, the initial prototype of what J. C. R. Licklider called the inter-galactic computer network (Wikipedia, 2018) has indeed becoming an inter-galactic network. Its history is complex and involves many aspects – technological, organizational, and community; its influence reaches not only to the technical field of computer communications but throughout society. The initial design of the internet was conceived by ARPA, was network that would be able to withstand a nuclear strike in event of nuclear strike. ARPANET development began with two network nodes which were interconnected between the Network Measurement Center at the University of California, Los Angeles (UCLA) Henry Samueli School of Engineering and Applied…

Network Congestion Control Mechanisms (Leaky Bucket VS Token Bucket Algorithm)

Internet, Networking, Telecoms

Network congestion is a challenging misnomer in today’s networking world as the number of connected devices continues to increase; this article enumerates different congestion control mechanisms and compares the leaky bucket and token bucket algorithm. INTRODUCTION Network congestion in data networking and queueing theory is the reduced quality of service that occurs when a network node or link is carrying more data than it can handle. Typical effects include queueing delay, packet loss or the blocking of new connections. A consequence of congestion is that an incremental increase in offered load leads either only to a small increase or even a decrease in network throughput. (Al-Bahaddili, 2012) Network resources are limited, including router processing time and link throughput. Resource contention may occur on networks in a number of common circumstances.…
