Ethernet tutorial for network performance, reliability


Contemporary Controls has created an online, interactive introductory tutorial for industry professionals to acquire the fundamentals of nine management features: IGMP snooping, rate limiting, virtual local area networks (VLANs), quality of service (QoS), simple network-management protocol (SNMP), port security, port mirroring, RapidRing redundancy, and trunking redundancy. "These features collectively affect the performance of your network by getting the best utilization of your bandwidth," says Bennet Levine, R&D manager for Contemporary Controls. "For example, rate limiting will prevent communication problems from one network affecting another network and IGMP snooping will prevent multicast traffic from overwhelming certain devices." Levine adds that this network performance tutorial will illustrate how the performance of a network can be improved through EICP, EISX, and EISB Ethernet managed-switches.
