Internet Exchanges – Place where the networks interconnect!

Earlier this month I got an opportunity to be part of IXP workshop in Kolkata. It was a 3-day event organised by ISOC Kolkata and supported by APNIC. There was also a workshop on DNSSEC and Champika Wijayatunga (from ICANN) was the instructor along with Anand Raje. It was a nice event and I come to know of other interesting projects ISOC Kolkata is doing like Indian IETF capacity building program apart from the IXP they are running in Kolkata. Mr Anupam Aggarwal and Anand showed the IX and it looks very good. I think it’s the first and only IX I know in India which is a real IX with proper policy. It’s an IX by a non-for-profit group, allows anyone to connect, a real layer 2 IX and welcomes anyone including ISPs, content players and root DNS servers. Presently IIFON-IX in Kolkata has few member ISPs besides the L root from ICANN and one of Verisign gTLD nodes (which host zones for .com, .net etc). I also saw a rack with some of Akamai CDN servers. This brings decent content right there. IX’es play an extremely important part of current internet infrastructure ecosystem. It’s very likely that content of this blog is travelling from my server to your browser from an Internet Exchange. 🙂
 

IIFON-IX Kolkata

 


 
I hope IIFON-IX does well in terms of becoming a key point for internet traffic exchange in Kolkata. There are a number of benefits of a good IX. Some of them are:

  1. Helps in reducing overall cost of bandwidth by keeping it local
  2. Helps in giving ultra-low latency interconnections among members
  3. Builds resilience across the internet by removing the dependency on transit players for local traffic and a lot more!

 
Besides IIFON-IX, I have been to BDIX in Dhaka, HKIX in Hong Kong, INEX IX in Dublin, LoNAP in London, Netnod in Stockholm etc. One thing common across all these exchanges is local involvement, usually a non-for-profit model and a collective community effort to make internet infrastructure better.
 

INEX – Dublin

 


 
Nick Hilliard (CTO at INEX) was kind enough to give me ride to one DCs hosting the IX.
Here’s a pic with Nick:

 
It was very interesting to see the use of passive DWDM MUX in the IX to connect between INEX PoPs across Dublin.

 
The one in this picture is an MRV MUX. Each port in passive MUX has it’s own wavelength and requires either pre-tuned or tunable SFP for that specific port. Such MUX can help to increase capacity on a pair of the strand by offering 40 channels and each can carry up to 10Gbps thus a capacity of 400Gbps for shorter distances (20kms or so).
The channels numbers mentioned on the port correspond to ITU Channel table and here’s the frequency wise table of actual channel number:

 

LoNAP – London

 
During my trip to UK, my good friend Andy Davidson helped in arranging a tour of LoNAP and Robert Lister was kind enough to give me a nice detailed tour of the IX fabric.
 


 

It was nice to see 10Gig flavours of Bidi SFPs i.e SFPs which do 10Gbps on a single strand of fibre. These are slightly different in terms of wavelengths as they run on 1270/1330 pair (opposite on the other side) while 1G Bidi optics runs on 1310/1490 pair.



 
I also saw a QSFP-LR4 which can do 100Gbps up to 10kms on a pair of fibre. 100Gbps or 100,000,000,000 bits per second or 100,000,000,000 zeros and ones flowing from fibre every second!

 
This runs on 1310mn and I don’t think there’s any Bi-Di option yet for 100G. There was ongoing 100G deployment at LoNAP during last year summers when I visited. One can spot an Arista switch with 100G ports.

 
And here’s a picture with amazing Rob after the IX-tour ended. 🙂

 

BDIX – Dhaka

Some pictures from Bangladesh Internet Exchange in Dhaka.


Mr Kabir from BDIX gave me an excellent tour of BDIX during my visit to Bangladesh back in 2015. You can see a lot of 1G fibre media converters in the rack. There’s quite a lot of fibre in Dhaka and cost of media converter is low and hence using them instead of the optical switch makes commercial sense though that’s changing fast. IX runs it its own dedicated building floor. IX has over 78 members.
Here’s a picture with Mr Kabir 🙂

 
Where should IX fabric be located?  
This is one of key question which comes in the mind of many engineers when talking of IX. Should IX be in a separate dedicated building or it should be rather in a commercial datacenter? The answer is simply that it depends. In larger cities in US or Europe, there are quite a lot of datacenters which are well connected. There’s reasonable competitive fibre available for potential members to reach switch fabric. While in the case of developing world here in Asia there might not be good commercial datacenter and hence one may end up in starting IX in a dedicated building. Also in developing world, there’s a considerable aerial fibre (legal as well illegal) and it’s usually easy for members to reach by pulling fibre or using someone else’s existing fibre. So, for example, IX’es like LoNAP, INEX, LINX, AMS-IX etc all run in well connected commercial datacenters. One can find the list of those datacenters by looking at peeringdb. While IX’es in South Asia like BDIX in Dhaka or NPIX in Nepal run out of their own buildings. Both approaches depend on lot more on existing fibre availability as well as rights of way charges. In the case of India, it’s a rather mix. IIFON-IX is new and runs out of a connected building in Kolkata in Sector 5, Kolkata while NIXI runs out of some good commercial datacenters in some cases and very poor datacenters in some other cases.
 
What’s wrong in India IX scenario? 
Well Indian IX scenario is a big mess. NIXI or National Internet Exchange of India is presently helping in exchange of 60Gbps traffic across NIXI Mumbai, Chennai, Noida, Kolkata, Bangalore, Hyderabad and Ahmedabad. There has been a jump in NIXI’s traffic in tier 1 Indian cities due to high traffic by Reliance Jio which happens to be exchanging traffic with Airtel via NIXI. But still 60Gbps is just nothing based on Indian scale in terms of a number of end users, amount of time Indians spend on internet etc. Except for NIXI Noida, Mumbai & Chennai, none is even crossing 200Mbps mark. NIXI’s IX in IT hub Bangalore is exchanging less than 1Mbps of traffic which is shameful (MRTG graph here). Same is true for Hyderabad and Ahmedabad.
Following things are wrong w.r.t NIXI and need to be fixed asap:

  1. The policy which allows only Indian ISP license holders to connect to IX (content players are not allowed!)
  2. The policy which does a ridiculous x-y on net inbound traffic and charges at a price of 1 INR /GB (which used to be 50 INR/GB in start)
  3. A misunderstanding that there’s  a mentality to keep above rules in order to keep large telcos. One can just let both: these stupid rules as well as large telcos to drop if they like to while having a large amount of smaller members over circuits of telcos
  4. Better choice of datacenters instead of sticking with not to well-connected datacenters

 
And of course, we need more efforts like IIFON and other players.
Remember: Somewhere up the transit path, there’s always peering! 🙂

Prefix hijacks by D-Vois Broadband

Today BGPmon reported about possible BGP prefix hijack of Amazon’s IP address space. Amazon announces 50.16.0.0/16 from AS14618. At 13:45:44 UTC / 19:15:44 IST D-Vois broadband started originating a more specific 50.16.226.0/24 in the table from AS45769.
One of example AS_PATH of this announcement: 198290 197264 197264 197264 29467 1299 9583 45769
Clearly, this leak was carried over by AS9583 (Sify) to AS1299 (Telia) and was carried over to rest of internet from there. There was a visible withdrawal of this request by 14:17:37 UTC / 19:47:37 IST.  So it was visible for approx 32mins.
Hard to guess on how come they did that. May be they are learning more specific /24 from Amazon in India and they leaked e-BGP routes in their IGP or it was just a hijack for some hard to guess reasons.
BGP Play link for the reference: https://stat.ripe.net/widget/bgplay#w.resource=50.16.226.0/24
Right along with this, there are multiple more visible hijacks by D-Vois including of Cloudflare, AT&T, Microsoft etc.

I think it’s very hard to say now what actually caused the leak.

18 Mar

20 mins of "I am about to die" moment

Last week I was on way from Kolkata to Delhi after spending time at ISOC IXP workshop. It was Jet Airways 9W 946 on 10th March 2017. The flight took off slightly late and 90% time went just fine. Original arrival time was 16:30 though it was expected to be little late.
 
Landing time…
At around 16:15 pilots announced “to prepare for landing” and cabin crew started collecting waste and getting people ready. I was sitting on the window seat and looking at clouds on my right. It was a usual view from the window and I usually like when the plane crosses over the clouds. It was little bumpy by 16:20 and that is usual behaviour. As it proceeded it went from “slightly bumpy” to “very bumpy” ride. Somewhere around 16:25 or so plane gave the first feeling of “free fall”. It’s was the same feeling as we get going down the roller coaster but 10x of that. Few people screamed. It reminded me of one of my previous travels from Malaysia to India in 2013 after APRICOT 2013 when the flight was very bumpy and also faced free fall at that time. Next after 2-3 mins plane had another free fall and it went for 10-15 seconds. A Japanese gentleman sitting next to me wasn’t wearing his shoes. One of his shoes literally touched my chest and fell on me. That was the first time I also got quite scared. I looked outside and the plane was all surrounded by clouds and nothing much was visible. Again just like the Malaysian flight in 2013 I felt for few mins that I was about to die. There were screams of people all around, few of cell phones, pens, shoes etc got all around. One person a bit away from me was shouting for help for someone around him. Next, there was another free fall like feeling. Lesser than last one but everyone was scared by this time. I stop looking outside the window as it was very scary. I thought planes cross clouds and this kind of thing never happens. Probably it’s some kind of technical failure and that’s about it. I could hear at least 5-6 distinctive voices of people chanting Hanuman Chalisa (हनुमान चालीसा ) and a girl right behind was chanting Om Namah Shivaya (ओम् नमः शिवाए) and she was repeating it really fast. All of that was further giving a scary feeling to mind that time has come. It was a very bad feeling. I saw on maps on the screen in the middle part of the plane – we were flying around Ghaziabad and plane was at 5000m.
 
Surely it was scary but at the same time, it was a feeling of regret about losing family members, people who we love, just about everything. I did not actually think that family members will loose me but it was a feeling other way around.  I realised I was way more scared this time as compared to the Malaysian flight and one of the reasons for that was the fact that I was on the Malaysian flight with my manager from the previous job. I wasn’t alone and we were speaking to each other at that time. I took my phone out while there were still bumps and wrote a message to my family members telling them that I was really scared. Next, I looked at Japanese gentleman on left. He was disturbed but very calm. He was silent and wasn’t showing any major expressions. I started speaking to him about bumps and “free fall like the feeling” of the plane. He mentioned that he was on way from Delhi to Kolkata a day back and flight was bumpy on that day too (of course less bumpy than the one we were in). That gave me a lot of confidence that it was just bad weather and nothing else. He asked me about what people are chanting all around and I told him the name of respective gods which people were chanting. Suddenly whole flight turned so spiritual. I felt much better by speaking to him and keeping my “I am about to die today” feelings aside. I asked him about his profession, he asked me mine and 2-3 mins passed with bumps.
Next, I saw outside plane was out of cloud cover and within 10 seconds captain declared that plane was out of high turbulence and we can expect a smoother ride. There were zero bumps and no further case of scary free feel beyond this point. Some people were worried as the plane was about to touch runway in fear that something is wrong in the plane but soon after flight just landed fine.
As the plane was out of runway and quite slow everyone was related. The person sitting on next seat looked behind and asked me for help to locate his pen. On the back side of the plane, there was a visible impact left with stuff lying all around. As we got out of the plane and were on way to terminal in bus people started talking about the experience. By this time there were a lot of “experts” saying pilot was in hurry to cross over. While hearing expert comments with a headache I felt I was back home. 🙂 I slept for rest of my way which is from Delhi to Rohtak by road and that helped to get rid of a headache.
And that is how “I am about to die” feeling ended and I thought I will hanging out on Earth for a while. Long time, long long time! 🙂
