Korenix is pleased to announce its JetNet 5828G IEC 61850-3 substation rated Layer3 switches now support advanced multicast routing (PIM-DM & DVMRP) for routing multicast traffic, such as layered movies, videos to different subnets of substation networks. The new DVMRP (Distance Vector Multicast Routing Protocol) or PIM-DM (Protocol-Independent Multicasting) enable users to flood multicast traffic downstream, while calculating the shortest path between each source and destination host group.
By building a source-rooted multicast delivery tree, the DVMRP prevents looping and determines the shortest path to the multicast traffic source. The PIM-DM, in its turn, builds a source-rooted multicast delivery tree for each multicast source by using router’s unicast routing table data, making the routing protocol independent. The support of the Dense Mode version of PIM further makes the JetNet 5828G more suitable for densely populated multicast groups that occur in LAN environments of substation-like network deployments.
JetNet 5828G series are 24+4G rackmount managed switches built with 3 modules that offer the flexibility to add up to 24 copper or 18 fiber ports while using different port combinations to best fit in your uniquely designed substation control room network infrastructures.
In addition to the newly added advanced multicast routing features, the switches also offer IP and VLAN routing, including static route, dynamic IP routing protocol (RIP V1/V2, OSFP V1/V2) for both low size and complex networks, as well as IGMP Multicast Management & MRoute for Multicast Routing. The JetNet 5828G series enable users to have highly reliable data transmission through Korenix’ MSR network redundancy protocol with seamless restoration and fast recovery time, as well as MSTP for complex network redundancy.
The switches conform with IEC 61850-3 & IEEE 1613 substation as well as NEMA-TS1/TS2 traffic and EN 50121-4 railway control standard requirements through their ruggedized features, such as -40~85oC operating temperature range with fan-free enclosure.
By combining all these features, the JetNet 5828G series provide excellent network connectivity, excellent data streaming quality, becoming high performance Layer 3 solutions for intelligent data distribution in substations, power utility networks, etc...
