RE: MIB Browser Recommendation

Wasn't there a nice one called Luna or something like that? 

After Net-SNMP, it was my favorite. I can't find it anymore though.

I've always wanted to write a new FOSS one in a modern framework (say, Qt).  
Haven't had the personal time to do it though (and it's unlikely I could 
attract funding to do it in today's leaning toward other technologies).  tkmib, 
which comes with Net-SNMP, *probably* still works?  I actually haven't run it 
in a while myself.

Howdy,



I have a request from management to 'measure our Superbowl traffic'.

In researching it I found last year they used 4 different CDNs, but I could 
never find out which ones.  Has anyone out there gotten the same request and 
figured out how to do that this year?



Thanks!

RE: [**EXTERNAL**] Re: Half Fibre Pair

[Fox, Barbara via NANOG]

I asked a submarine guy how much the fibers can carry because this sounded low 
to me.  His response:

it depends on the type of cable. Older cables (with embedded dispersion 
compensation) have a lot less capacity and I have seen some as low as 1Tb/s per 
fiber pair and some as high as 10Tb/s per fiber pair. All newer D+ Cables that 
have been deployed in the last 5 years and will be the only cables deployed 
going forward can easily carry 20Tb/s of capacity per fiber pair. Something 
Like Havfrue can support 22T per fiber pair and there are 8 fiber pairs for a 
total of 176T.

It is also possible for a consortium member to own a full + a fractional fibre

Have many of those higher strand count cables been proposed that have

You guessed it... it's not traditional telco's pushing cable builds anymore.



It's a lot cheaper to power a 300 km cable than a 3,000 km cable.


It's not uncommon to have multiple fibre pairs on shorter spans and 
fewer on longer/express ones. But yes, longer systems cost a lot more 
money; for everything, not just power.

Because of the way current submarine cables are being built (mainly by

fibre pairs does not make sense anymore, especially for them since they 
would be partnering with some carriers along the route.


I mean, you're already laying it. Fibre, itself, doesn't cost that

Cables currently being laid in the sea are going in at anywhere between

MIB Browser Recommendation

[Graham Johnston]

We have historically been a CentOS shop when it comes to choice of Linux OS, 
and in turn that meant, largely out of laziness, that we used mbrowse to browse 
mibs and perform simple snmp test queries to devices, just manual work until we 
find what we want and configure something in our NMS. We are moving some 
servers to Ubuntu now with the change to CentOS/RHEL, and we are curious what 
others are using for a SNMP/MIB browser. An FOSS choice would be on top on our 
list as it is just easy to install from the repo, but I'll take any 
recommendation that people have.

Thanks,
Graham

Summary: advertise-peer-as

[Jared Mauch]

I’ve closed the form for responses.

There were 102 people who self-selected to participate. 

Around 25% of you have this configured as a default in your network.

At 20940 we are asking our networking partners to configure this facing us such 
that we can receive the routes from some of the stub networks we operate.

I was also told there’s some interesting behavior in IOS-XR, if a peer is in 
the same peer-group and based on the order of the peers coming up, the behavior 
may be different where routes may be suppressed.

You may also want to read up on the "send-transit-peer” command for your 
network.

Thanks for responding, and if you have a BGP peer with 20940 please set 
advertise-peer-as or similar.  It may help keep more traffic on direct links as 
a result.

It would be based on the amount of capacity each fibre in the overall 
system can carry across a given line system span.


So say a cable system is able to carry 960Gbps per fibre pair, and it 
has 5 fibre pairs, that means a half fibre pair purchased by one of the 
consortium members would be 480Gbps.


It is also possible for a consortium member to own a full + a fractional 
fibre pair, e.g., two and a-half fibre pairs. In such a contract, for 
example, say a 24 fibre-pair system could carry 1.2Tbps per fibre pair, 
that member would have 3Tbps of capacity.

It is language used in the submarine world, where a member of the consortium 
may not be able to afford a full fibre pair on the system.

Don't take it literally :-).
