The massive development of virtualized infrastructures, Internet of Things (IoT), and Wireless
Sensor Network (WSN) in recent years has led to an increase in quality requirements for the …

The paper is devoted to a research area focused on solving problems associated with
outages and connection interruptions in modern IP networks. The goal is to design and …

IP Fast Reroute (IPFRR) is resiliency technology to provide fast traffic recovery upon link or
node failure for mission critical services. This technology is able to recover impacted traffic in …

After a link or router failure within a network, a process of network convergence starts.
During this process, the network is experiencing serious connectivity issues, in which …

The demand for faster failure-recovery in pure intra-domain IP networks has led to the
development of several IP Fast ReRoute (IPFRR) mechanisms. However, these …

After the failure of a network node or a link, a period of impaired connectivity is experienced
until the network reconverges. During this period, specific destinations are not reachable …

Abstract IP Fast ReRoute (FRR) mechanisms have been proposed to achieve fast failover
for supporting Quality of Services (QoS) assurance. However, these mechanisms do not …

In circuit switching and packet switching networks, if a router or a link gets failed, the packets
that are travelling on the failed link, path or router will be lost and dropped until network self …

Over the last few years, Internet Protocol (IP) networks have made significant progress,
allowing to provide voice over IP (VoIP) and other real-time services. The quality of provided …

The IETF currently discusses fast reroute mechanisms for IP networks (IP FRR). IP FRR
accelerates the recovery in case of network element failures and avoids micro-loops during …
