Re: Packet Loss/Latency Reports
said by koitsu  :
IMPORTANT: The problem at hand with SE might not have ANYTHING to do with Juniper equipment! It might be something else; I have no idea. But when Kat says the equipment is oversaturated in regards to how many pps (packets per second) the equipment can push out, the first thing I think of is their Junipers. Software routing, ugh.
Either you were using a beta product or one of their 'lollypops'. Juniper used to let you have the OS to install on a pc to play with so you could teach people how they work without using a router that was in production.
Junipers are complete hardware routers. Whoever told you they were software routers was incorrect. There is no way you could push the following amount of data through a software router.
M5 - 3.2-Gbps full duplex (6.4 Gbps total)
M10 - 6.4-Gbps full duplex (12.8 Gbps total)
M20 - 12.8-Gbps full duplex (25.6 Gbps total)
M40 - 25.6-Gbps full duplex (51.2 Gbps total)
and the processor in each can handle 40 million packets per second.
Oh and btw, a very common router used at ISPs the Cisco 7513 spec'd to the max only handles .5 million packets per second.

| Interesting post, scooby. I've taken up the details with you in private, but the Juniper in question was an M40 (I provided pictures so you can see that I'm not talking out my rear  ).
It's likely that the unit was misconfigured, and it's highly likely that they're _still_ misconfigured. I no longer work there (thanks for laying off 85% of your work force, Verio!), but I still occasionally see "Verio networking madness," especially since InterNAP has a peering link with Verio.
Thanks for clearing up the software vs. hardware issue as well. The individuals who told me they were software-based was one of the Verio network administrators I knew, which may explain how and why the units were misconfigured.
Either way, thanks for stepping in and saying something. *thumbs up*
