Routing failures are common on the Internet and routing protocols can not always react fast enough to recover from them, which usually causes packet delivery failures. To address the problem, fast reroute solutions have been proposed to guarantee reroute path availability and to avoid high packet loss after network failures. However, existing solutions are often specific to single type of routing...
To reduce influence of node failure and achieve high reliability in communications, research on node protection algorithm is needed. In this paper, we first provide an overview of current research of redundant tree algorithm (RT). Then we propose a new algorithm called single node protection algorithm (SNP) based on previous redundant tree algorithm, which is used to achieve recovery form single node...
This paper proposes a Resilient Overlay for Mission Critical Applications (ROMCA); a novel operator-independent overlay architecture providing a resilient and reliable service across wide-area networks. One feature of ROMCA is that its overlay topology can be altered according to the underlying network conditions. Moreover, resilience is achieved by combining centralized topology construction control...
This paper proposes a novel recovery mechanism from large-scale network failures caused by earthquakes, terrorist attacks, large-scale power outages and software bugs. Our method, which takes advantage of overlay networking technologies, pre-calculates multiple routing configurations to prevent possible simultaneous network failures and selects one configuration immediately after detecting the failures...
This paper develops a novel mechanism for recovering from dual link failures in IP networks. The highlight of the developed routing approach is that a node re-routes a packet around the failed link without the knowledge of the second link failure. The proposed technique requires three protection addresses for every node, in addition to the normal address. Associated with every protection address of...
