FYI...
The following are a series of tests run at a Boeing facility to
test the throughput of Cisco routers and hybridges.
Test 1:
Setup: Two HP 4972A Analyzers were configured to generate packets
at a 45% background load using the provided stats program. The com-
bined output of the two traffic generators was 14,713 packets (64
byte packet size) per second - as indicated on the traffic monitor
screen of the monitors.
A Cisco CGS router containing a csc3 processor running the 8.2 o/s
software, a 2E2T MCI card w/ v1.5 micrcode was used int he testing.
A Cisco AGS+ was used as a sink for directed packets from the packet
generators. the AGS+ contained a csc3 processor running 8.2 o/s
software and (2) MEC6 cards w/ v1.1 microcode.
Packets were addressed to the sink from the traffic generators. A
third HP 4972A Analyzer was used to measure traffic using the stan-
dard stats program.
The following results were obtained:
Bridging - 14,713 pps
IP - 14,713 pps
IPX - 14,713 pps
DECnet - 12,900 pps
A second test involved using the AGS+ as the router and the CGS as
the sink. The tests were run between ports eth/0 and eth/1 of the
first MEC card.
The following results were obtained:
Bridging - 14,713 pps
IP - 14,713 pps
A/Talk P2 - 14,713 pps
A third test involved using the AGS+ as the router and the CGS as
the sink. The tests were run between ports eth/0 of the first MEC
card and port eth/5 of the second MEC card.
The following results were obtained:
Bridging - 14,713 pps
IP - 14,713 pps
IPX - 14,713 pps
DECnet - 12,900 pps
A fourth test was conducted using 4 HP test generators on two input
networks (ports eth/0 and eth/1 of the AGS+) and with the CGS con-
figured as a sink (off ports eth/6 and eth/7 of the 2nd MEC). This
test involved loading the the ethernets to obtain an aggregate thru-
out the cbus in both ip routing and bridging modes. This test was
performed w/o the fast switching microcode for the cbus controller.
The following results were obtained:
Bridging - 15,000 pps
IP - 19,200 pps
A fifth test utilized the same setup, but packet lengths were changed
to 1500 bytes. The 2 ethernets were loaded to 8.5mb/s and 9.5mb/s
respectively. No loss of data was experienced in this scenario. The
total throughput was measured at 18mb.
A sixth test utilized the same setup as test 4, but combined IP and
DECnet. The mix was 1/3 DECnet and 2/3 IP.
The following results were obtained:
Mixed load - 16,900 pps
I thought the this would be of interest.
