Multi Protocol Label Switching technology or shortly MPLS has been proposed to speed up the traffic flow
in the network using labels. Thus, MPLS allows Internet Services Providers (ISPs) to provide better Triple Play
Services (i.e. voice, video, and data). In this project, the impact of MPLS technology on the Triple Play Services
is evaluated based on the average throughput of the network, total number of packets received at destination
nodes, and packet loss rates, and this is compared to that provided by traditional Internet Protocol (IP) networks.
The results showed that MPLS performs better since it utilises all the available paths to the destinations. This
work concludes that MPLS allows ISPs to provide better triple play services for end-user.

In this project, we consider classes of algebras to have two binary algebraic operations. They have been
introduced and have been called dialgebras by Loday. We deal with the classification problems of these classes
of algebras in low-dimensions cases. The first class called the class of Diassociative algebras appears as a
generalisation of the Associative algebras. We give complete classification of complex Diassociative algebras in
dimensions two and three. Here we give a complete list of isomorphism classes of four-dimensional Diassociative
algebras as well. Another class of dialgebra is closely related to Diassociative algebras called Dendriform algebras
that has important applications in quantum mechanics and quantum field theory. We give the description of
isomorphism classes of two dimensional complex Dendriform algebras.
