Re: New Member's Configured on BIRD

by David Farmer III

In a way both are correct. The Northern Lights Gigapop (AS57) is the ISP transit provider AS operated by the University and is the AS peering at MICE. Northern Lights Gigapop is simply a DBA of the University. AS217 is the source AS for traffic from the University's campuses. AS1998 is the source AS for the State of MN and MNSCU's campuses. There are a number of other ASes that AS57 is transiting to MICE as well. I can create a new AS-set in the RADb containing the ASes that AS57 is transiting to MICE, if folks are interested let me know. Is anyone connected to MICE generating BGP or traffic filters from the RADb?

Your assumption is wrong unfortunately. I wish I had made a mistake, but stats.micemn.net's Cacti config is 64bit for gathering of stuff. And using SNMPv2 according to the configuration.

Cacti Graph using SNMPv1?

by Justin Krejci

'micemn-gateway-2.micemn.net - Traffic - Gi0/2' in Cacti is exhibiting signs of using SNMPv1 counters (frequent gaps at higher bandwidth usage) Is this a known issue? If not I presume someone at iphouse can fix this easily. The "Fix64bit" plugin for Cacti is great for correcting this condition on the fly if my assumption on the problem is correct. ######################################################################## To unsubscribe from the MICE-DISCUSS list, click the following link: http://lists.iphouse.net/cgi-bin/wa?SUBED1=MICE-DISCUSS&A=1

Re: Akamai Traffic on MICE

by David Farmer

I was planing to make that part of the discussion with Akamai. However, even without MICE we were going to need more servers for next fall. It seems our servers were shedding demand much of the spring. Since school is out, our demand has dropped by about 50% over the last 2 weeks, and is down about 65% from our Spring peak about 6 weeks ago.

Re: Akamai Traffic on MICE

by David Farmer

As was noted we installed a 2nd GigE between the two switches yesterday. Things are looked good last night we peaked at 1.7Gbps most of that coming from the U's Akamai Stack. Akamai tells me we are maxing out our servers again, it looks like we were maxing them out most of the spring anyway. The Akamai servers are putting out a little less than 2G from about 7am to 11pm. I believe we are seeing more traffic in the evening going to MICE because most of the other Gigapop networks have more of a business day demand curve, so Akamai serves more of the demand out of MICE in the evening as demand from the Gigapop networks slack off. So I think things are much better now, we should get the new switches installed and people moved over but we shouldn't have to rush it. The University will work with Akamai to get more servers over the summer, but I would hope we would have everyone moved over to the juniper switches long before that happens.

I think the Cisco default in a PortChannel is to load balance by src-mac, which might have much help in the current situation, since most of the traffic is coming/going to one mac addr. You might want to try changing it to src/dst IP for a better distribution of flows across both links, or even per flow, if the box supports it.

It looks like Akamai has found a sweet spot they tend to do that, the link between the switches peaked up to about 850 and backed off and is hovering abut 650Mbps for the last hour or so.

Specificly one thing that could be done is if SDN could be moved from the 4500 onto the 3560, and FWR could string another cross-connect temporarily between the 3560 and the other fiber "uplink" port on the 4500, we could change those two gig ports into an Etherchannel.

Akamai Traffic on MICE

by David Farmer

The 10G Akamai stack at the University is having an affect. The University turned up routing from the GigaPOP to MICE on its 10G link Tuesday around 8pm. The new paths were also announced to the Akamai route collector around that time too. Akamai started using these new paths around 1:30 in the afternoon on Wednesday. The University's 10G link peaked a little over 1G around 9:30pm last night. The bottleneck is the 1G link between the CNS 10G switch and the 4500. It was saturated from about 6:30pm to 9:30pm at about 950Mbps. Some of us are organizing to rectify the situation ASAP. There are some workarounds that could help in the very short-term, yet this morning, and we are looking to get the new Juniper switches with 10G up-links installed ASAP However, the earliest that can happen it this afternoon, as the switches are down in Mankato with Jay. There is a plan to get them up to 511 by mid-afternoon. Also I'll be watching the links and can modify our announcement to the Akamai route collector if necessary. Things are going to be fluid today. I'll just say that this is the kind of problem I like to see, if you are going to have to deal with any problem. That is the problem of over succeeding. -- =============================================== David Farmer Email:farmer@umn.edu Networking & Telecommunication Services Office of Information Technology University of Minnesota 2218 University Ave SE Phone: 612-626-0815 Minneapolis, MN 55414-3029 Cell: 612-812-9952 =============================================== ######################################################################## To unsubscribe from the MICE-DISCUSS list, click the following link: http://lists.iphouse.net/cgi-bin/wa?SUBED1=MICE-DISCUSS&A=1

MICE Traffic

by Jay Hanke

We have seen a dramatic growth in traffic on the exchange. The GE link between the CNS remote switch and the Main switch is running about ~950 Mb/s. We're going to need to make some upgrades shortly to avoid degrading services. Perhaps more quickly than originally planned. We may need some volunteers and stuff depending on the course of action.

Re: Traffic between 10Gig & 1Gig Switches

by Jeremy Lumby

Looking at the graphs, it is apparent that most of the traffic is going to one MICE member. I would believe that they would be inclined to want to move to a 10 gig link since it is really benefiting them, and since it is the same fiber cross connect, the only real cost would be the 10G optics. The second thing that is much more long term is I believe that the link between the switches should be 10Gig. This would not allow a single 1Gig member to do so much unexpected traffic that effects the exchange as a whole, and we would be able to watch trends, and adjust as needed before the situation became urgent.

I'm guessing that is CDN related? The link between the CNS switch and the MICE switch shot up to ~850Mbps today. Too bad that is only a single gig connection! It is great to have the traffic on the exchange, but we should probably deal with this nearly saturated link fast. Here are a few possible solutions: 1) Add another Gig connection. We'd probably need to pay FWR for a cross-connect (CNS is paying for the first one) with this option; 2) Use one of the new Juniper switches with a 10Gig interface and connect that to a 10Gig interface on the existing MICE 10Gig switch, then move some of the 1Gig members over to those ports. This would require purchase of 10Gig optics for the Juniper and the existing 10Gig MICE switch; 3) Move some of the higher bandwidth MICE members to the 1Gig ports on the 10Gig switch. Would this increase the FWR cross-connect charges for those members if they are going from copper to fiber? 4) Encourage MICE members on the 1Gig switch to upgrade to a 10Gig connection; 5) Ask the U to not advertise some of the members on the 1Gig switch to CDNs (if that is the cause of the traffic load). This is a bummer if you are one of the networks that gets left out. I really don't like this option -- we are finally getting real traffic on the exchange and then we'd be cutting back.
