Ideas to products (Shark Tank(-ish) @ Austin)
by Mehmet Akcin 01 Jul '19

01 Jul '19

Hey there, I am trying to put together an event at NANOG Austin (will submit pc when CFP is open). So many of us had very interesting ideas over the years. Some of these ideas became products or companies making life easy for engineers and operators. Could there be other ideas waiting to be supported? Perhaps. I am sure you all watched shark tank! In simplest words i am trying to organize an event very similar to Shark Tank!( we will call it some other name tho) There will be some known investors on the stage and you will 5 mins for your pitch and 10 mins to answer questions, and hopefully make a deal. I will help those who want to pitch their idea with their p&l , presentation and other things as they needed. Please contact me if you have any questions offlist and want to pitch your idea. We need a single paragraph to get you started. Mehmet -- Mehmet +1-424-298-1903

Exactly, while the service edge topology might be dynamic as a result of horizontal scaling the core on the other hand I'd say should be fairly static and scaled vertically, that is I wouldn't want to scale core routers horizontally and as a result have core topology changing with every P scale out iteration at any POP, that would be bad news for capacity planning and traffic engineering... > > I’ve tried to write some of my experiences here > (https://null.53bits.co.uk/index.php?page=few-larger-routers-vs.-many- > smaller-routers). > The tl;dr version though is that there’s rarely a technical restriction to having > fewer large routers and it’s an operational/business impact problem. > I'll give it a read, cheers. adam

few big monolithic PEs vs many small PEs
by adamv0025＠netconsultings.com 28 Jun '19

28 Jun '19

Hi folks, Recently I ran into a peculiar situation where we had to cap couple of PE even though merely a half of the rather big chassis was populated with cards, reason being that the central RE/RP was not able to cope with the combined number of routes/vrfs/bgp sessions/etc.. So this made me think about the best strategy in building out SP-Edge nowadays (yes I'm aware of the centralize/decentralize pendulum swinging every couple of years). The conclusion I came to was that *currently the best approach would be to use several medium to small(fixed) PEs to replace a big monolithic chasses based system. So what I was thinking is, Yes it will cost a bit more (router is more expensive than a LC) Will end up with more prefixes in IGP, more BGP sessions etc.. -don't care. But the benefits are less eggs in one basket, simplified and hence faster testing in case of specialized PEs and obviously better RP CPU/MEM to port ratio. Am I missing anything please? *currently, Yes some old chassis systems or even multi-chassis systems used to support additional RPs and offloading some of the processes (e.g. BGP onto those) -problem is these are custom hacks and still a single OS which needs rebooting LC/ASICs when being upgraded -so the problem of too many eggs in one basket still exists (yes cisco NCS6k and recent ASR9k lightspeed LCs are an exception) And yes there is the "node-slicing" approach from Juniper where one can offload CP onto multiple x86 servers and assign LCs to each server (virtual node) - which would solve my chassis full problem -but honestly how many of you are running such setup? Exactly. And that's why I'd be hesitant to deploy this solution in production just yet. I don't know of any other vendor solution like this one, but who knows maybe in 5 years this is going to be the new standard. Anyways I need a solution/strategy for the next 3-5 years. Would like to hear what are your thoughts on this conundrum. adam netconsultings.com ::carrier-class solutions for the telecommunications industry::

Crowdfunding critical infrastructure
by Eric S. Raymond 27 Jun '19

27 Jun '19

The members of this list are, I think, much more aware tham most that a lot of critical Internet software is maintained by unfunded volunteers, and of the systemic risks that result from this. I'm attacking the problem at the root, applying what the Internet has taught us about decentralization and avoidiing single poimts of failure. In part because I'm currently struggling with medical bills (nothing life-threatening, just ankle surgery) but I've been worrying about the larger problem for a decade. Please read http://loadsharers.net Of course I would like everyone on here to take the pledge and spread the word in technical communities where they have influence. But beyond that, there are several members of this list who are clearly qualified to join as advisers. We're going to need that as the Loadsharers network scales up. -- <a href="http://www.catb.org/~esr/">Eric S.

Comcast Outage - East Coast?
by John Von Essen 27 Jun '19

27 Jun '19

I just saw a 40% traffic drop on my routing core (East Coast based) across all my BGP peers. None of my transit peers flapped or had any issues other than the traffic drop. Almost all the complaints of connectivity issues were people using Comcast, so right now thats the only common thread. Anyone else see this? It appears to have resolved after about 5 mins. -John
