Switch Architecture

Each TigerSwitch 16 unit is a "store-and-forward" device. Every

packet it receives is stored in a buffer so it can be checked for

validity before being forwarded to another port. In addition, the

switches feature a non-blocking design that allows simultaneous

wire-speed transport of multiple packets at consistently low

latency.

An aggregate address table that can hold 8,192 entries is

provided for learning, filtering and forwarding. Addresses are

automatically learned by each TigerSwitch 16 unit and main-

tained in the address table to enable the switch to perform filter-

ing and forwarding at line-rate speeds. When a packet contain-

ing a destination address that does not appear in the table is

encountered, the packet is broadcast to all segments.

Packets are filtered if their destination address is on the same

segment as their source address. By confining network traffic to

its respective collision domain, filtering reduces the overall traf-

fic on the network.
