Selection Guide for New Campus Network-Grade Optical Switches
This guide explores how to design a future-ready campus network and compares three leading families of campus switches: Huawei CloudEngine S6730-H, Cisco Catalyst 9300, and Ruijie S6510. Why 10G Switches Are Essential for Campus Networks?Uplink ports towards the legitimate DHCP server are defined as “trusted”. If DHCPOFFERs are seen coming from any untrusted port, they are dropped. L2 device only – connecting end users! L2 device only – connecting edge switches! Fibre to building distribution, or is copper enough? But would you be. Just as the plumbing in a large stadium or a high-rise building is designed for scale, purpose, redundancy, protection from tampering or denial of operation, and the capacity to handle peak loads, the network requires similar consideration. If the pressure is coming from building-to-building aggregation, routing boundaries, or operational blast radius, then. Huawei campus switches are ideal for building future-proof campus networks with simplified management, high reliability, and service intelligence, across industries such as enterprises, governments, education, finance, and manufacturing.

Improving Relay Protection Efficiency
Focusing on directional overcurrent relays, the study examines optimization-based methods for tuning key relay parameters, which include the pickup current and the time multiplier setting, to minimize the total relay operating times and ensure reliable protection. This research uses a genetic algorithm (GA) based approach to optimize digital relay coordination for the 3x15MVA, 33/11kV M2 injection substation in Jabi, Nigeria. The study involves modelling the substation and its key components within MATLAB/Simulink, enabling a simulated environment to test. Relay protection technology plays a vital role in fault detection, isolation, and recovery, evolving with intelligent algorithms, digital equipment, and automated coordination to enhance grid reliability. Both deterministic and. One of the promising ways to develop protection and control systems is the development of fundamentally new algorithms for recognizing emergency modes.
