Enhanced Bit Repair IP Fast Reroute Mechanism for Rapid Network Recovery

Abstract

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 management and reliability of underlay communication networks. Existing converged networks must therefore guarantee specific quantitative and qualitative parameters of different network communication services to meet customer requirements. However, the quality of the services operated is very negatively affected by an unpredictable failure of a communication link or a network node. In such situations, communication is typically interrupted for a period that is difficult to predict, and which can lead to significant financial losses and other negative effects. Internet Protocol Fast Reroute (IP FRR) technology was developed for these reasons. The paper presents the proposal of the new Enhanced Bit Repair (EB-REP) IP FRR mechanism, which offers significant improvements over its predecessor, the B-REP mechanism. The B-REP offers protection against a single failure and only for selected critical IP flows. The EB-REP provides advanced protection against multiple failures in a protected network domain and the protection can be provided for all network flows. The EB-REP calculates alternative paths in advance based on link metrics, but also allows the construction of alternative paths independently of them. The construction of alternative FRR paths uses a standardized tunneling approach via a unique field Bit-String. Thanks to these features, EB-REP is an advanced contribution to solving IP FRR-related problems, which enables the use of EB-REP in many network deployments, but especially in network solutions that require reliable data transmission.

Distributed WSN Vulnerability Remediation System Based on Mobile-N Policy

“…Simulation experiments verify the superiority and adaptability of the MECHR algorithm to the ever-changing 3D underwater monitoring environment [15]. Papan's team proposes a new augmented bit repair mechanism that computes alternative paths in advance based on link metrics but also allows alternative paths to be constructed independently of them, and the experimental results show efficient correctness in multifaceted faulty problem solving and the ability to protect all network flows [16].…”

The New Label Bit Repair Fast Reroute Mechanism

“…We have been researching FRR since 2015, when our first Multicast Repair (M-REP) mechanism was developed [53]. In other works, efforts were devoted to its extension [54] and simulations of other advanced mechanisms for fast network recovery [13], [55 This means that if a path exists, the algorithm will find it and use it. The advantage is also the possibility to manually set your own backup path by the network administrator [55].…”

“…FRR [2], [3] are technologies and mechanisms that are designed to minimize network recovery time after a network outage through an alternative pre-calculated route, which helps to minimize connection interruptions and reduce negative impacts on the services provided [4]- [6]. Routing protocols and mechanisms: research focuses on improvements to existing routing protocols such as OSPF (Open Shortest Path First) [7], [8], IS-IS (Intermediate System to Intermediate System) [9], or BGP (Border Gateway Protocol) [10]- [12], but also on designing new mechanisms IPFRR (Internet Protocol Fast Reroute) [13], which would ensure effective routing [14]and thus minimize outages [4], [15]. Detection and diagnosis of outages: Research work seeks to improve methods and tools for the detection and diagnosis of network outages, which is important for rapid repair and restoration of connectivity [16]- [18].…”

Design of a Technique for Accelerating the WSN Convergence Process

“…FRR mechanisms serve to ensure fast and reliable transmission in a network, minimize the impact of an outage on operation, and thus improve the availability of services. The principle of operation of the FRR mechanism is presented in [49].…”
