Response to the problem



HLD of SDN, IS-IS and ECMP
SDN refers to a software-controlled approach to networking by API’s.
IS-IS is a link state routing protocol that provides fast convergence and scalability.
ECMP refers to the routing technique of forwarding packets to multi best paths of the same cost.

Recommendations
Service providers and network operators should migrate to SDN ecosystem.
A proper framework must be developed that includes re-skilling of technical staff.
A hybrid method to be considered instead of a blanket approach.


Future work
Mobile transmission networks
Other routing protocols
Incorporate other transmission performance metrics
Energy efficient devices
