Servers could be haunted by a ghost from the 1980s, as hackers have started abusing an obsolete routing protocol to launch distributed denial-of-service attacks. DDoS attacks observed in May by the ...

Network protocols are formal standards and policies consisting of rules, procedures, and formats that define how data is exchanged over networks. They ensure that devices can communicate effectively, ...

Network layer routing protocols provide the communication protocols and algorithms for determining routes to every destination and also for distributing the routing information throughout the 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 ...

Data center routing is evolving. Some might even say, “finally!” the industry has been working too long with traditional routing protocols from the telecom and enterprise network environments. Now is ...

Networks function and flourish because they deliver reliable and fast communication over large distances. And while people often marvel at the speed, it's the reliability -- made possible through the ...
