Routing protocols designed for low power and lossy networks (LLNs) have become pivotal in realising the vast potential of the Internet of Things (IoT) and wireless sensor systems. These protocols, ...

Routing protocols play a critical role in the functioning of the Internet and the services built upon them. However, many of these protocols were developed without security concerns in mind. For ...

The open systems interconnect (OSI) model provides the standardization of a communication system by breaking it into seven layers. From lowest to highest, these are physical,data link, network, ...

Performance of a network is based on routing protocols. RIPv1, RIPv2, EIGRP and OSPF are the dynamic routing protocols being used in the practical networks to propagate network topology information to ...

I love new security testing tools. There is nothing quite like finding some magical bits of code allowing you to use and abuse protocols in unique and unnatural ways. I was introduced to Loki at ...

How does an SDN interoperate with the rest of the network? SDN Doesn't Operate Alone Software Defined Networks don't operate alone. They will have to interoperate with other SDNs and with other parts ...
