Product Overview
Introduction
8× 10/100/1000Base-T port Gigabit Ethernet Switch with
Broadcast Storm Control
Live-GSH8T Gigabit Ethernet Switch is an auto-sensing and auto-negotiating Gigabit Ethernet
Switch with Broadcast Storm Control capability. Its eight 10/100/1000Mbps Gigabit ports provide
10/100/1000Mbps connections to PC with gigabit cards or gigabit switches
Live-GSH8T’s unique switching fabric provides non-blocking full wire speed for all ports. Auto
MDI/MDIX function is provided for conventional uplinking to another switch/hub using ordinary
straight-through cable. Each port provides up to 2000Mbps in full duplex mode. With its
auto-sensing, Live-GSH8T automatically detects the speed of the devices you plug into, and routes
the incoming data to its destination. Its auto-negotiating function allows existing devices running at
different speeds to communicate easily within the same network.
Broadcast Storm Control
The Live-GSH8T automatically filters out the broadcast traffic when the broadcast packets exceed
5% of the total traffic. Broadcast storm can significantly impede the performance of the network.
The Live-GSH8T protects your network from such situations.
Store-and-Forward Architecture against Packet Loss
When network is under heavy traffic, the shared memory buffer in the switching devices might yield
incorrect detections due to overfed memory buffer. This setback can happen either when data is
transmitted in IEEE802.3x Full Duplex or Back Pressure Flow Control mode. To solve this problem,
Live-GSH8T utilizes a fixed memory buffer allocation with Store-and-forward transmission to
ensure an effective buffer allocation for each port.
Store-and-forward transmission controls data flow from transmitting to receiving nodes with the
receiving buffer threshold adjusted to an optimal value, thus guaranteeing against all possible packet
losses.
Active Flow Control
Live-GSH8T Gigabit Ethernet Switch implements in full duplex mode a flow control that is
compliant to IEEE 802.3x standard. While in half duplex mode, it employs an optional Back
