The TL-SG1005D from TP-Link is a high-performance, low-cost and easy-to-use 5-port Gigabit Ethernet Switch that would allow you to upgrade your old network to 1000Mbps network.
The Gigabit Ethernet switch would let you speed up your backbone connections. All the 5 10/100/1000Mbps auto-negotiations ports support IEEE 802.3x flow control for Full-Duplex mode and backpressure for Half-Duplex mode. The switch is based on non-blocking switching architecture that forwards and filters packets at full wire-speed for maximum throughput.
The switch is also capable of MAC address auto-learning and auto-aging. The standards and protocols that are supported are IEEE802.3, 802.3u, 802.3ab, 802.3x, CSMA/CD, TCP/IP. Large and bandwidth-intensive files can be transferred faster.
Users across home or office networks can share and move large, bandwidth-intensive files faster. The switch is based on Green Ethernet technology. Some of the other features of the switch are automatic power down of ports that have no link; wire-speed performance; plastic case; desktop or wall-mounting design.
The TP-Link TL-SG1005D 5-port Gigabit Ethernet Switch is available from Play.com for £13.89 delivered.
