Today, the overloaded networks increasingly entail high operational costs but may not
generate new revenues accordingly. Legacy network elements are reaching end-of-life and …

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 …

Failure management and cost-aware traffic engineering are two important tasks done in
Network Operation Centers (NOC). These are performed by expert technicians who must …

Software defined networking (SDN) is one of the most popular network technologies which
provides an adaptive, agile and flexible network management and visibility. Although SDN …

Failure recovery has been a hot potato in the maintenance of networks, including software
defined networks (SDNs), for many years. To guarantee the network availability in SDNs …

In recent years, the emerging paradigm of software-defined networking has become a hot
and thriving topic that grabbed the attention of industry sector as well as the academic …

Software-defined networking (SDN) is an emerging trend where the control plane and the
data plane are separated from each other, culminating in effective bandwidth utilization. This …

Fault tolerance is one of the most desirable properties in the optical network since a large
amount of data will be lost if the failure recovery cannot be well achieved. The software …

This paper proposes a scheme to reduce the number of flow entries permanently stored in
an OpenFlow switch and the number of configuration messages from a controller in a …

Software-Defined Networking is considered as a prominent architecture in the field of
networking. The separation of control plane with data plane provides an efficient way to …
