Nixi

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. :)  

So it seems like apart from voice interconnect issues, Jio is also facing routing issues on the backbone. I ran a trace to one of IP’s on Jio network allocated to end customer - 169.149.212.122. I ran trace from all Indian RIPE Atlas probes measurement here. There seem quite a few RIPE Atlas probes which are giving latency on 150ms + range. Seems like they are downstream or downstream of downstream of Tata Comm’s AS4755 and routing is happening via Singapore!    

K root in Noida seems to be not getting enough traffic from quite sometime and connectivity does seems bit broken. This is a blog post following up to Dyn’s excellent and detailed post about how TIC leaked the world famous 193.0.14.0/24 address space used by AS25152. It was good to read this post from RIPE NCC written by my friend Emile (and thanks to him for crediting me to signal about traffic hitting outside!)  

Today I met a good friend and he has recently moved back into Rohtak (like me!) and was crying over BSNL’s issues. He has issues of unstable DSL due to last mile and I told him that even if last mile works well, BSNL still has got ton of issues with their IP backbone traffic.   It’s Sunday late night out here in India and I am having really pathetic connectivity with just everywhere except Google. With Google only key difference I noted is that my TCP session to Google’s services is terminating at Mumbai and not Delhi anymore. First and formost, I did trace to spectranet.in (which is last company I was working for) to see how is my latency with server hosting it:

Just finished with SANOG 26 conference and tutorials. It went very nice. Interestingly this time conference did not start early morning like it did in SANOG 24 at Noida. It was rather late in afternoon. Also, on very good note - there were less Govt. bureaucrats to bore attendees with usual stuff they always talk about but have very little idea. One specific interesting presentation was  Opportunities and Challenges for Broadband Wireless in India by Prof Abhay Karandikar (from IIT Mumbai). In start I felt it to be usual crappy 5G talk but later realized it was much more interesting. I loved the idea “Have 2Mbps everywhere static broadband and not some absurd number on mobile wireless broadband as we hear in case of 3G/4G. Although 2Mbps now is much slower and I would rather suggest that we target for 10Mbps everywhere (something which can be supported by copper/coax/fiber hybrid) but anyways it was nice refreshing talk. His thoughts were interesting but mostly impractical since had high dependence on useless project like NOFN. For the next part, we had a nice theme of keeping network simple which everyone kind of liked. Simplicity in Network Design & Deployments by Dany Pinto (from Colt) and Unified Forwarding with Segment Routing by Mohan Nanduri (from Microsoft Azure Cloud WAN team) were part of that. Santanu Dasgupta gave a presentation about Challenges of L2NID based Metro-E Architecture for vCPE/NFV Deployments and kind of confused everyone. :P
