Introduction
1–5
•
Uses “on the fly” cut–through switching technique to transport packets
•
Minimum latency of packet transmission (leading edge to leading edge) of
less than 20 microseconds when using cut–through switching
•
Supports transparent bridging function
•
Provides a 256 KB buffer for each port
•
Routing table contains 4K entries per port to store MAC address for attached network
nodes
•
Automatically learns MAC addresses to build the routing information database
•
Uses a fast hashing scheme to retrieve information from the routing table when
making routing decisions
•
Provides frame filtering and forwarding functions for each port, which are capable of
filtering and forwarding Ethernet packets at line speed
•
Nonblocking crossbar switching matrix allows concurrent operation of up to eight
Ethernet segments
•
Uses back pressure to eliminate frame loss by blocking traffic from end stations or
segments connected directly to the DEL8X when its buffers fill
•
A LED indicator panel for monitoring the overall condition of the DEL8X, including
utilization rate and collision
•
Port network status equalizer display
•
Conforms to the IEEE 802.3 and IEEE 802.3u specifications (10Base–T and 100Base–TX
standards)
•
Basic configuration can be performed using the Configure button (plug and play)
•
Automatic polarity detection and correction permits automatic adjustment for wiring
errors
•
Transparent to all higher level protocols
•
Provides self–diagnostics
•
Flexible installation for the desktop or rackmount
