Fast ReRoute Model with Realization of Path and Bandwidth Protection Scheme in SDN
Advances in Electrical and Electronic Engineering, 2020 The paper proposes a Fast ReRoute model with the realization of path and bandwidth protection scheme, which can be used in MPLS for SDN. The task of calculating the set of disjoint primary and backup paths during fast rerouting was reduced to solving the

Trade-offs between Risk and Operational Cost in SDN Failure Recovery Plan
Future Internet, 2022 We consider the problem of SDN flow optimization in the presence of a dynamic probabilistic link failures model. We introduce a metric for path risk, which can change dynamically as network conditions and failure probabilities change.

Improved Fast Rerouting Using Postprocessing [PDF]
2019 38th Symposium on Reliable Distributed Systems (SRDS), 2019 To provide fast traffic recovery upon failures, most modern networks support static Fast Rerouting (FRR) mechanisms for mission critical services. However, configuring FRR mechanisms to tolerate multiple failures poses challenging algorithmic problems.

A Fast Failure Recovery Scheme for Fibbing Networks
IEEE Open Journal of the Communications Society, 2020 Fibbing is a network technology that can provide flexible routing in IP networks. In a Fibbing network, the network controller cleverly broadcasts link state advertisements (LSAs) of the open shortest path first (OSPF) protocol to generate fake nodes ...

Short Schedules for Fast Flow Rerouting
CoRR, 2018 This paper studies the fundamental problem of how to reroute $k$ unsplittable flows of a certain demand in a capacitated network from their current paths to their respective new paths, in a congestion-free manner and fast. This scheduling problem has applications in traffic engineering in communication networks and has recently received much attention ...

Fast heuristics for delay management with passenger rerouting [PDF]
Public Transport, 2013 Delay management models determine which connections should be maintained in case of a delayed feeder train. Recently, delay management models are developed that take into account that passengers will adjust their routes when they miss a connection. However, for large-scale real-world instances, these extended models become too large to be solved with ...

A Rerouting Framework Against Routing Interruption for Secure Network Management
IEEE Access, 2019 In this paper, we consider the problem of routing interruption, which has received significant interest in recent years. To solve this problem, rerouting is an effective way.
