Enhancing Large-Scale Network Infrastructures through High-Performance and Reliable JetNet 6524G, the Back-bone 24 Full Gigabit Stackable Layer3 Managed Switch!

Why Layer 3 and Where to Use
Due to continuous technological developments throughout the world, industrial networks are becoming more complex and require reliable and real-time connectivity. When building large networks a number of problems need to be encountered: usually the hosts located in different broadcast domains cannot communicate by themselves; each of the IP subnets is a single broadcast domain; users in different IP Subnet/VLAN cannot access the same Public Server; HTTP, FTP, Video, Movie can not be directed to target users through remote service provider, etc.

Hereafter, switches are needed to guarantee the communication between different subnets. Routers or Layer3 switches help users interconnect two different VLANs by executing inter-VLAN routing, or routing of traffic between VLANs. Broadcast traffic is then terminated and isolated by these Layer 3 devices. Layer 3 is the 3rd level of the OSI 7 layers, known as IP layer. Layer 3 switch is also known as Multi-Layer switch which includes the wire-speed layer 2 MAC switching and layer 3 IP routing capability. A Layer3 switch can filter the packets of a particular protocol to allow users to further reduce network traffic. It actually performs the same tasks as router, yet it overcomes the performance disadvantage of routers, layering routing on top of switching technology.

Benefits of JetNet 6524G Layer 3 Managed Switch
Korenix intelligent JetNet 6524G Layer 3 stackable managed switches, equipped with huge network capacity of 24 full gigabit ports plus 4 Gigabit SFP combo ports help users to easily manage routing between different network segments while delivering maximum throughput and flexibility for high-density and ultra high-speed connection..

Triple Layer 3 Routing (IP, VLAN and Multicast routing

The JetNet 6524G IP routing layer contains the IP forwarding layer, Address Resolution Protocol (ARP) mapping layer and Routing Tables. With IP forwarding table, the JetNet 6524G provides wire speed IP and VLAN inter-routing. Users can easily configure multiple IP subnets through a single port or the VLAN interface and assign these subnets to the physical interface. The routing table can be updated according to the routing information defined by configured static route or learnt by dynamic Routing Protocols. The dynamic Routing Protocols supported by JetNet 6524G are RIPv1, v2, OSPFv1 and V2

Aiming to route multicast streams such as movies, videos, industrial automation streams through different subnets, in addition to IP and VLAN routing, the dynamic Multicast Routing protocols, such as PIM-DM and PIM-SM, DVMRP , IGMP v1/v2/v3, are needed. Korenix JetNet 6524G outstands from other layer 3 switches by its multicast routing feature. With IGMP snooping and IGMP router port selection protocols, the JetNet 6524G acts as an access level switch or aggregated switch, so that the clients can be divided into different subnets for wire speed routing and for exchanging routing information with other L3 routers/switches.

VRRP Layer 3 Default Gateway Redundancy
To further ensure the high reliability of an environment, the JetNet 6524G supports the VRRP (Virtual Router Redundancy Protocol) protocol allowing the hosts to continuously direct traffic to the default gateway without the default gateway configuration change.

High Network Capacity
The JetNet 6524G switches are equipped with 24 full gigabit ports plus 4 Gigabit SFP combo ports to deliver maximum throughput and flexibility for high-density and ultra high-speed connection. For building large-scale networks, JetNet 6524G series provide up to 192 Gigabit ports per stack and 384G bandwidth through 8 unit stacking ability, secured stack cable and dual 10G stack backplane.

Backbone Network Reliability and Advanced Management
The switches operate as backbone solutions to form gigabit MSR redundant ring networks and further ensure the network reliability through advanced management protocols such as LLDP and JetView pro, DHCP option 82, QoS, LACP, IGMP Snooping, SNMP etc.

Taking full advantage of these features, JetNet 6524G can find its various applications in collision avoidance systems, automatic road enforcement, vehicle notification systems and other traffic control systems.
