Traditional networking is hardware-based, having the control plane coupled with the data
plane. Software-Defined Networking (SDN), which has a logically centralized control plane …

Software-defined networking (SDN) plays a crucial role in the enterprise and wide-area
networking. The increasing demand for strict service-level agreement applications on the …

Deployment of new optimized routing rules on routers are challenging, owing to the tight
coupling of the data and control planes and a lack of global topological information. Due to …

Fast recovery from link failures plays a major role in networking due to loss of packets and
transmission delay. Link failures must be addressed immediately as it may lead to …

Communication networks require high availability to provide reliable services to users. One
of techniques maintaining high availability of communication networks is fast failure recovery …

The widespread use of technology has made communication technology an indispensable
part of daily life. However, the present cloud infrastructure is insufficient to meet the …

In Software-Defined Networking (SDN) links and switches (nodes) from data plane suffer
from failure and impact network operations. In the presence of such failures, switches can …

Link backup is an important factor in the fault tolerance of SDN. The current research
directions are proactive schemes and reactive schemes. The proactive schemes deploy the …

Software-defined networking (SDN) is a great innovation, which makes the network
programmable so that it is easier to achieve failures recovery. Through pre-programmed …

Software-defined networking (SDN) enables a network to be programmable, which makes it
easy for the network to recover from failures. Upon failure, network can revert to operational …
