High Bandwidth and Performance

The JetNet3018G equipped with 16 100M Fast Ethernet plus 2 Gigabit Ethernet ports, totally requests at least 7.2G backplane for wire-speed and bi-directional transmission. To meet the requests, there are 2 types of system architecture - nonblocking and blocking.
In non-blocking architecture, the switch fabric should provide higher backplane than are the front ports’ requests. No matter it’s a one to one or fully mesh network, the throughput is always 100% without any loss.
The blocking architecture is usually implemented in non single chipset solution. Limited backplane may cause traffic jam when there is a heavy loading transmission among the ports.

The JetNet 3018G embedded 12.8G backplane is much higher than the system requires. All the traffic can be switching without blocking and loss. Up to 9K Jumbo frame allows transmitting larger files with less segments. The high bandwidth and performance solution guarantees the high capabilities of the product.

What is Jumbo Frame?

The typical Ethernet frame ranges from 64 to 1518 bytes. This is sufficient for general usage. However, when users need to transmit large files, the files may be divided into many small size packets. While the transmitting speed becomes slow, 9KBytes Jumbo frame can solve the issue.

Examples:
Transmitting large files, like the size of the LCD’s bitmap type circuit may reach up to 800MB. Network servers usually progress backups for lots of large files.

To run Jumbo Frame within the industrial environment, all the switches in the network must support Jumbo Frame feature. Once there is any Jumbo Frame unaware switch within the network, the Jumbo Frame will be dropped.
Korenix provides complete Jumbo Frame supported switches for allowing users to easily build a Jumbo Frame network. The JetNet 3018G acts as an entry level Jumbo frame switch to bypass up to 9K Jumbo Frame packet from the PC to the uplink network of higher level backbone switches.
