Live-GSH8T Gigabit Ethernet Switch

1 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

Pressure Flow Control to stall the incoming data when port buffers are saturated. With this flow control mechanism, it can be ensured that frames dropped during transmission are reduced to a minimum.

Non-blocking Wire Speed

Live-GSH8T’s non-blocking cross-bar matrix architecture provides high-end performance for departmental and workgroup environments at a fraction of the cost of similar devices. Typically, this type of architecture was found only in high-end switches designed to handle huge corporate networks. With bandwidth needs and network efficiency concerns, Live-GSH8T’s switching fabric design is the perfect answer for solution.

System/Port Status Information at a Glance

There are 2 sets of LEDs on the front panel: System LED and Station port LEDs,. The System LEDs consist of the Power LED, the BCST(Broadcast Storm Control)/Diag and OvUn_Flow LED. The station LEDs consist of the 10M Link/Act, 100M Link/Act, 1000M Link/Act with 2 color LED to indicate full-duplex or half-duplex.

What’s Broadcast Storm Control

Broadcast Storm is the result of too much broadcast traffic in the network. Broadcast packets are sent to every stations in the network, thus increase the overall network traffic. Broadcast storm are likely to decrease the network performance significantly. Broadcast Storm occurs usually when there is a loop formed in the network or when a particular application creates unordinary amount of broadcast packets. The Live-GSH8T has built-in broadcast storm control which filter out the broadcast traffic when it exceeds 5% of total traffic.

Solution for the digital media age

In the age of digital media, the computer has become the storage center for DV, DVD video, and digital pictures. Furthermore, the majority of the worldwide TV format will turn to HDTV and other digital standard in the next few years. The demand for faster network will increase dramatically. Gigabit Ethernet will make playing DVD quality video over the network a reality. In addition, copy Gigabytes of data over network will no longer be a time consuming process. With the Live Series Gigabit Ethernet switch, building a network capable of fast large file sharing and real time play back of high quality audio/video is simple and affordable.

Why Copper-wired Gigabit Connection?

With the tremendous success of Ethernet in LAN, twisted-pair cable has become the most ubiquitous networking media all over the world. It also costs less than the fiber-optic cable. Thus, it is very convenient to choose a copper-wired gigabit switch such as Live-GSH8T, since you can easily set up a gigabit backbone using the kind of twisted-pair cable so ordinarily used in 10/100BASE-TX environment.
