A New Bit Repair Fast Reroute Mechanism for Smart Sensors IoT Network Infrastructure

Area of Science:

• Computer Science
• Network Engineering
• Telecommunications

Background:

• Modern IP networks face increased demands from Internet of Things (IoT) devices and critical services.
• Network reliability, fault tolerance, and minimal packet loss are crucial for meeting service demands.
• Network convergence after failures can be time-consuming and unpredictable.

Purpose of the Study:

• To introduce a novel Fast ReRoute (FRR) mechanism called Bit Repair (B-REP).
• To enhance network resilience and minimize packet loss in packet-switched networks.
• To ensure reliable communication for IoT devices, particularly sensor data transmission.

Main Methods:

• The B-REP mechanism utilizes a specialized BIER (Bit Index Explicit Replication) header field (Bit-String).
• It pre-calculates an alternative, hop-by-hop path for packet routing.
• The mechanism is designed for networks using link-state routing protocols.

Main Results:

• B-REP provides explicit indication of an alternative path via the Bit-String header.
• It offers full repair coverage throughout the network.
• The proposed solution leverages standardized mechanisms for path definition.

Conclusions:

• B-REP offers an effective solution for network fault tolerance and minimal packet loss.
• Its application is suitable for packet-switched communication networks, especially those using link-state routing.
• B-REP can significantly improve the reliability of IoT communication, ensuring data integrity from sensors.
