Architecture and Technology
Router 650 Hardware
The routing engine also has 128 kilobytes of high-speed cache to handle even
a large number of end-to-end conversation streams, and eight megabytes of
routing table memory (expandable by another eight to sixteen) to handle
even the largest (1000 or more) router networks. It has a PCMCIA flash card
for nonvolatile storage of the preloaded operating system code and of the
configuration data. The flash card is removable, and sizes from four to
twenty megabytes are supported.
The pipelined multiprocessor architecture is especially powerful when the
topology requires routing between various media types; the DLA modules
hide the performance-robbing idiosyncrasies of some network media.
Ethernet-to-Ethernet routing performance is unaffected by the presence of
WAN and token ring source-routed traffic. All WAN-specific processing, such
as compression, X.25, and frame relay, is handled by the WAN DLA. The
performance of the memory bus is more than one gigabit per second. The
throughput of the management bus (whose performance is not critical to
operation) is 50 megabits per second. Preliminary testing of overall routing
performance demonstrates IP and IPX routing at more than 80,000 packets
per second, and bridging at more than 100,000 packets per second.
