CUBIC is congestion control algorithm designed keeping in mind the
issues with networks having high bandwidth delay product. It is
current congestion control algorithm being used in Linux kernels.
The algorithm modifies the linear increase function of TCP to a
cubic function. It also has a better response time and maintains
the fairness against concurrent TCP flows. It exhibits a TCP
friendly nature over a much vast range of values for Round Trip
Time, Bandwidth and Error Rate. But, it also has a problem of
aggressive increase and slow convergence of flows causing prolonged
unfairness for short lived flows. We have tried to understand these
implications of the CUBIC TCP algorithm and explore reasons and
suggest solutions for them. The solutions suggested are not purely
mathematical but, they lay a foundation for a full fledged
algorithm gives hints towards what improvements should be
implemented to better the performance of CUBIC. For studying and
analysis we have implemented CUBIC in Linux and simulated it in
ns-2.
Vision for Interactivity: By Priyanka Sharma To build a
Watermarking Model Using MATLAB. There is an increasing need of
software so a battle begins between in order to provide copyright
protection for intellectual property that's in digital format. For
instance, the widely used DCT coefficients used in the JPEG and
MPEG-2 standards. In fact when working on the DCT coefficients
domain one may take advantage of the relative independence between
the maximum allowable perturbations at every coefficients.
Management is creative problem solving. This creative problem
solving is accomplished through four functions of management:
planning, organizing, leading and controlling. The intended result
is the use of an organization's resources in a way that
accomplishes its mission and objectives. A manager must organize
these functions in order to reach company goals and maintain a
competitive advantage. Putting these plans into action requires
forming groups as underlings must be directed to complete the plan,
and the plan's development must be directed by control. In order
for these practices to succeed in an operational manner, an
understanding must be reached concerning the basics in which these
practices are in relationship to the business structure. Planning
is the ongoing process of developing the business' mission and
objectives and determining how they will be accomplished. Planning
includes both the broadest view of the organization, e.g., its
mission, and the narrowest, e.g., a tactic for accomplishing a
specific goal.
