Overall, ITxPT helps optimize fleet management and supports the future of autonomous vehicles and smart cities. Presented by Mark Cooksley. #PlainlyExplained -
RSPAN in Industrial Networks
Industrial networks face challenges like large geographical dispersion and limited physical accessibility, complicating traffic monitoring and analysis. RSPAN (Remote Switched Port Analyzer) addresses these issues by enabling remote monitoring from a centralized location. This technology allows administrators to mirror traffic from remote ports, gaining insights into network performance, troubleshooting issues, and enhancing security without needing physical presence at each switch. RSPAN also facilitates compliance with data retention regulations and quick issue resolution, making it an essential tool for maintaining reliable and secure industrial networks.

MQTT in Industrial Networks
The Industrial Internet of Things (IIoT) requires efficient data exchange, but traditional protocols are inefficient for the many small, resource-constrained devices now common in industrial systems. MQTT, a lightweight publish/subscribe messaging protocol, addresses these challenges by decoupling senders and receivers using a broker, minimising overhead, and optimising for low-bandwidth, high-latency networks. MQTT supports scalability, varying levels of Quality of Service, and robust security features like TLS and SSL. Its wide adoption in industries demonstrates its effectiveness, making it a key tool for modern industrial automation networks. Presented by Mark Cooksley. #PlainlyExplained -
Secure Boot in Industrial Networks
is a security weak spot. Traditional measures often fail to protect firmware integrity, exposing systems to threats. Secure Boot addresses this by ensuring only trusted firmware is executed during boot-up, verifying firmware integrity and authenticity. This process protects against unauthorized firmware modifications, enhances network resilience, and helps comply with security standards. Secure Boot is essential for maintaining the integrity and security of Ethernet switches. Presented by Mark Cooksley. #PlainlyExplained -
Access Control Lists in Industrial Networks
security measures, these networks become vulnerable to unauthorised access and cyber threats. Access Control Lists (ACLs) provide a comprehensive solution by regulating and controlling network traffic at Layer 2 and Layer 3 of the OSI model. Implementing ACLs offers enhanced network security, granular control over traffic, compliance with industry regulations, improved performance, and reliability. Premium industrial Ethernet switches already support ACLs, making them a powerful tool in fortifying industrial networks and ensuring secure and efficient operations.

Layer 2 Firewalls in Industrial Networks
This video emphasises the critical importance of Layer 2 firewalls in securing existing industrial automation networks. With increasing cyber threats, network security has become a pressing concern. Layer 2 firewalls offer defence-in-depth by segmenting the network, efficiently filtering traffic based on MAC addresses, and transparently protecting diverse industrial protocols. These firewalls provide an additional layer of security to safeguard critical assets, ensuring resilient and secure industrial operations in today's fast-paced automation landscape.

Ethernet Switch Stacking in Industrial Networks
Discover the revolutionary potential of Ethernet Switch Stacking in transforming industrial networks. This video highlights the limitations of traditional industrial Ethernet switches, such as bottlenecks and scalability issues, and introduces the value of Ethernet Switch Stacking. By interconnecting switches to create a high-bandwidth backplane, this solution enhances performance, simplifies management, and ensures high availability through redundancy. The streamlined approach enables network administrators to manage the entire stack as one unit, saving time and effort. Embrace Ethernet Switch Stacking to unlock the true power of industrial networks and stay ahead in the ever-evolving world of industrial automation. Presented by Mark Cooksley. -
Multi-Chassis Link Aggregation in Industrial Networks
In the dynamic realm of industrial automation, the need for robust communication networks is paramount. This article explores the transformative power of Multi-Chassis Link Aggregation (MC-LAG) in industrial networks. Without MC-LAG, conventional link aggregation falls short, leaving networks vulnerable to single points of failure and suboptimal load balancing. MC-LAG, however, offers a revolutionary approach, ensuring high availability, load balancing, and network resiliency. By seamlessly rerouting traffic, eliminating blocking, and enhancing scalability, MC-LAG emerges as a game-changer for industrial automation networks, enabling uninterrupted operations and optimised performance. IT professionals should consider MC-LAG as the key to unlocking the full potential of their industrial networks. Presented by Mark Cooksley. #PlainlyExplained -
Ethernet Ring Protection Switching in Industrial Networks
This video explores the transformative impact of Ethernet Ring Protection Switching (ERPS) in industrial automation networks. ERPS, a resilient network redundancy solution, ensures reliable and uninterrupted communication in dynamic industrial environments. By simplifying network topology, providing rapid fault recovery, and supporting various ring configurations, ERPS minimizes downtime and prevents data loss during network failures. Its standardised approach enables seamless interoperability among different manufacturers' equipment. This article emphasises the growing importance of ERPS in industrial networks and highlights its accessibility, making it an indispensable technology for building robust, scalable, and reliable infrastructures.
