It’s natural to assume that computer clocks in servers, workstations, and network devices, each with its own clock, are inherently accurate, but that may not always be true. In modern computer networks, time synchronization is critical because every aspect of managing, planning, securing, and debugging a network involves determining when events happen, and when poor synchronization happens, the result can be missed call handovers, capacity reductions, and network down time. Especially now with the proliferation of 4G and 5G networks, in addition to multitude of applications, all require greater accuracy.

Developed in the 1990s, the Purdue Model, formally the Purdue Reference Architecture (PERA), is a reference data flow structural model for industrial control system (ICS) security, concerning physical processes, sensors, supervisory controls, operations, and logistics. Purdue Reference Model, provides a model for enterprises where end-users, integrators, and vendors can collaborate in integrating applications at key layers of the enterprise network and process infrastructure.

The Radio Access Network (RAN) is an expensive, proprietary equipment that connects to cellular antennas, processes the signals and sends it to the core network. Service providers, who needs to stay agile to meet the growing demands of enterprise and consumers, find RANs to be a bottleneck and are moving to Open RAN and vRANs to reduce costs.

The demand for more agile and secure Wi-Fi connectivity continues to grow as organizations cope with increasing numbers of client and IoT devices connecting to their networks, astronomical amounts of data generated and demanded, such as for bandwidth-hungry video streaming, and speeding up their transition to the cloud – all requiring significant bandwidth to move efficiently. Wi-Fi 6E, an expansion of the Wi-Fi 6 standard, allows access to the 6 GHz frequency band providing room for growth with wider channels for low latency.

As many enterprises embrace digital transformation and make significant investments in their shift to the cloud, the challenge now becomes how to fully leverage and realize a cloud-first SASE architecture for security and scalability. Even as more and more data and workloads spread among remote users and cloud services, application traffic and security policy enforcement should not be backhauled to data center before being forwarded to the cloud, instead it should be applied to wherever users are located.

P4-programmable switches, such as Intel® Intelligent Fabric Processors (Intel® IFPs), can enhance Ethernet switching with high-performance, and real-time edge-to-cloud telemetry for higher visibility and manageability. Intel® Tofino end-user programmable Ethernet switches can accelerate packet processing for edge and cloud data centers, high-performance computing (HPC) and communication service providers.

The worlds of IT (Information Technology) and OT (Operational Technology) are converging and when implemented properly, can vastly improve efficiency, reduce errors, cut costs, and enhance workflows, greatly benefiting manufacturing, utility and energy companies, transportation, retail, medical, and communication industries. Apart from the advantages, this convergence also opens OT to a vast and advanced cyberthreat landscape.
