That's not enough information, to say the least. It heavily depends on
what you are doing to 'manage' the routers and which network management
protocol is involved. MCC does not generate any traffic by itself. It's
all under your control how you setup alarms, recording, etc.

5873.2 | CMIP, 1 minute delay | BPSOF::MONDVAI | | Thu Feb 17 1994 06:09 | 8 |
| Robert,
thanks for your quick response. The routers are WANrouter 250s (CMIP),
routable protocols: DECnet, TCP/IP. Each site has a VAX and (1-6) PCs.
We have to monitor the state of the routers and VAX nodes every
minutes.

5873.3 | Just ONE case | BIKINI::KRAUSE | European NewProductEngineer for MCC | Fri Feb 18 1994 04:32 | 26 |
| I did a 'show node xxx all status' and captured the traffic with a LAN
analyzer. There were 10 frames with a total of 731 bytes. Given an X.25
segment size of 64 bytes, it would account for 15 segments. A packet
size of 128 would yield 11 packets. Multiply this by the number of
VAXes/routers polled and you get a rough estimate on the amount of
traffic per poll cycle (1 minute in your case).
PLEASE don't take this as gospel. It was just a one-shot to get an idea,
not a real proven calculation.

| Robert,
thanks again, this is enough to start with.
