starting from tomorrow, we’re launching another edition of PLNOG conference. as usually, I’d like to invite you to join us. I’ll be delivering session about Segment Routing with Piotr Jabłoński during second day of the conference, at 4:15pm. as Segment Routing was already covered couple of times, we’ll focus on practical deployment guide in existing networks. I’ll be also demoing some of the aspects we’ll cover live during the session....
for the first time in a few years I took three weeks of vacation. …and this is starting to catch up with me :) i took few books with myself, but only some of them are worth mentioning - like ‘Hit refresh’ by Satya Nadella (though I have not read it yet) and ‘Now. The physics of time’ - I am in the process and it is fascinating to read....
plnog, plnog and… it’s gone. twentieth edition - how the time flies… from the beginning we knew it may be hard, but we can make it. ’let’s target 60 people!’ was the second decision after we agreed to ‘do this’ and create PLNOG. 124 of you showed up. i don’t really remember all of the things that happened that day. and that was only 10 years ago! i remember only the fact, that we couldn’t fit you in one of the Cracows Wawel room that Andrzejs team was able to secure for this experiment....
after being absent on three PLNOG editions, i finally made it to the conference and to agenda. my presentation slides are here. i tried to cover everything important from networking perspective starting from IMP and ending on NPU, reprogrammable ASICs and what’s lurking in the future. of course if you’ll vote by your surveys, i hope to get back to delivering presentations. what’s interesting is that Krzysztof Kania also picked up architectural topics in his article about first routers - go read!...
…and that’s good thing. with only two weeks to seventeed edition of PLNOGa we have bunch of interesting news. conference, that we started by discussing BGP, MPLS-TE and RSVP and role of 10GE interfaces (we’re in Europe and that was 2009!), today focuses on deploying SDN, and influence of IoT to service provider networks. we’re also discussing public cloud, hybrid cloud, software defined data centers (SDDC) and consequences of proliferation of overlay networks....
I was taking part of PLNOG for the last two days. i didn’t have opportunity to take part of the last edition and it’s a shame - we created this conference with Andrzej Targosz. a lot changed during last couple of years. but what was always key of the whole PLNOG - community - is only developing. i’m not about the direction, but the sole fact we have a lot of discussions about direction gives hope....
as you probably know already, next, jubilee edition of PLNOG is just around the corner. apart from stand and presentations, we’re be there with extended team to discuss our new products and solutions. and traditionally, we’ll also conduct couple of workshops for people interested in Cisco solutions: Advanced BGP workshops Deploying IPv6 MPLS basics one novelty we’ll offer is first of a kind offering in Poland - service provider design workshop....
seventh edition of PLNOG just finished, but what’s more - we just did deliver also first edition of new project - EURONOG. during last three days we’ve had a lot of presentations, discussions, Q&A sessions and discussion panels. see you during next conferences!
“Cisco eats in own dog food” or as you may elite-write-it: c15c0 d06 f00d. we announced participation in ISOC IPv6 day as a first vendor. some parts of our infrastructure serve IPv6 natively, but that’s a great opportunity to test it at scale - including hardware and software for systems that’s used for our internal and Customer services. among other things we’re testing AnyConnect 3.0 with native IPv6 support (public version is going to be available in couple of months), ACE 3....
i’d like to thank everyone that was part of last PLNOG edition. we introduced education track - that was your idea, voiced in chats and in surveys. it seems that the idea was right, so on september PLNOG edition we’ll continue with MPLS and QoS. also according to announcements, we did joint session with Rafał about architecture of ethernet switches and IP routers. i hope you liked it. we still miss real life use case sessions provided by you - service providers....
it seems Google decided to reach out to wider community and use the freely available network stack for it’s own MPLS prototyping. the effect is complete MPLS LSR prototype described during recent NANOG 50 talk that’s also available as video. of course it’s quite interesting to see Google experimenting with that kind of solutions - maybe it will be connected to OpenFlow as non-academic exercise? will it become mainstay of new service provider networks?...
for some time Jim Gettys on his blog is writing a lot about problems caused by buffers, queues and other congestion avoidance mechanisms. you should really read about them. especially, if you’re in this group that believes big buffers solve all of the problems, and dropping traffic is absolute evil. nowadays it should be treated as absolutely normal thing - in most of the real life cases. on the upcoming, sixth PLNOG we may be able to tackle this problem (if there will be space in agenda), and have a shot at myths and legends related to network QoS....
i was stubborn - and while from the very first moment we’ve had a lot of challenges with the hotel infrastructure, i was able to run xTR routers during last PLNOG for LISP. no, it’s not about programming Cisco routers with LISP, but about new concept of Location/ID Split, that is new concept enabling you to treat traffic engineering in internet differently. in short - we still serve traffic like we always did (backward compatibility), but by assigning users and companies IPv4 and IPv6 addressing from special pools, we can treat this traffic in a different manner....
during upcoming PLNOG i’ll cover two relatively new features available in Cisco gear. LISP which stands for Locator/ID SPlit is first, deployed and available both commercially and as open source code) solution that can enable internet to scale out without further growth of routing table size. it also brings advanced traffic engineering capabilities to pure IP networks. LISP was invented and is being actively developed by Cisco employees, working in different teams across research and development departaments....
fifth PLNOG edition is coming in on 21st and 22nd of october this year. this time we’ll have Merike Kaeo delivering keynote session. her topic of choice? security - suprising, isn’t it? :P as you can imagine we’re buttoning up agenda and it will be published soon. in the meantime, we already have over 200 attendees registered, which is great result given you still don’t know what you’ll be able to see :)...
for all those of you concerned with vanishing of BGP blackholing PL project page - please calm down. we’re moving. current page is here. in other news, i’ll host discussion panel on upcoming PLNOG 2009. we’ll touch on blackholingu and other best practices to increase security of internet infrastructure. i’ll be joined by Konrad Plich from TP SA and polish CERT representatives.
in a month from now, we’ll be launching first edition of PLNOG conference. we’re working to deliver a lot of interesting sessions. apart from many abroad presenters, we’ll host also our own, polish specialists. you’ll have a chance to meet Wojtek Apel (3S), Tomasz Paszkowski (nasza-klasa.pl) and Marcin Mazurek (Allegro.pl). somewhere in the agenda there’s also my session about MPLS Traffic Engineering. before that, on Saturday and Sunday, I’ll deliver hands-on workshops on BGP and MPLS....
summer holidays are in full swing - starting from 26th of July i’ll be running Cisco Academy courses at PROIDEA for CCNP. everyone who’s eager to have a good time learning and discussing technologies (way outside of official curriculum) should immediately contact academy reception. independently of that, we have two large conferences coming. at Cisco Expo 2008 i will deliver sessions on network architecture that minimizes the chances of becoming a victim of a DDoS attack and becoming part of botnet....
