Last few weeks went extremely busy. Feb + the first few days of Mar were spent in the Philippines for APRICOT 2023. This was the first time I spent close to 15 days at an APRICOT event due to involvement in workshops. Anyways, I enjoyed it. So far I have done this workshop on network automation twice (at SANOG 38 and APRICOT 2023) and both times I get attendees with a different sets of skillset. In SANOG 38 I assumed I will see network admins but the majority of attendees were sys admins. In APRICOT 2023 I assumed there will be sys admins but the majority of attendees were network admins. 😄

Last month I got access to Jio 5G like everyone else around in Haryana. They are running a beta program with uncapped data for now. Overall it works fine for usual stuff (web surfing on popular sites, YouTube videos, music streaming etc) but 464XLAT seems to be a little buggy in IPv4 hardcoded destinations. Initially it was giving quite a few issues but many of them seem to be fixed in last few days.

Last year had many interesting developments and one of that has been object storage. For those unaware, object storage is de-facto cloud storage which stores data as objects instead of file system architecture. This gives the option of simple plug-and-play horizontal scalability. It became popular when Amazon Web Services (AWS) launched S3. The idea was straightforward - pay-as-go storage with a few cents/GB/month charge to store data and a few cents/GB to egress data. No need to plan storage, no need to plan hard disk, storage servers, or rack capacity but a simple pay-as-you-go opex cost. Plus top tier cloud players do offer redundancy of data. The API replies with “success” on uploads only when data is replicated to multiple datacenters.

Next month will be APRICOT 2023 which is exciting. The last in-person event of such kind was in Feb 2020 in Melbourne. Later APRICOT 2021 & 2022 were completely online (similar to other NOGs). This year’s APRICOT will be in Manila, Philippines. On the agenda will be meetings with network operators, CDNs and internet exchanges in the region. Along with that, I will be doing a 5-day long workshop on “Network Automation for Network Engineers”. This will be a step-upgrade from the last one I did at SANOG 38. One day extra gives me the option to add a CRUD-based app besides REST APIs. Plus I think 5 days will be the longest ever I have ever done in past.

More and more EVs (Electric Vehicles) are visible on the road as time is passing. On two-wheelers, it’s getting quite common. I don’t have sales stats but I can see as many as 1-2 scooters are electric out of 10 in the area. In cars, it’s still uncommon but one can see a few Tata Nexon EV and Toyota with green number plates when driving around in Delhi, besides many parked electric cars at terminal 3 in Delhi airport parking.

I was recently discussing with a friend Jio’s Fifa streaming issues. Considering PNI capacity challenges with other telcos, I wonder if they were serving FIFA streams out of their network or if it would be on some CDN like Akamai. As I was testing, I noticed a couple of megs of flow data with my provider’s local IP. Turns out that was a local Google GGC node in Rohtak and as I try to connect to it, it replies on HTTP port 80 and 443. The port 443 response is rather more interesting because while connecting to IP throws an error, it does give me the SSL certificate out of handshake and now I know it’s indeed Google! :)

In Aug of this year, I posted about three-phase power. Subsequently, I had a discussion with a friend from Delhi about bonding neutral with earth/ground at the distribution panel. He has a commercial load of 20KW delivered via three phases and his electrician advised him to bond neutral with the ground. We both were curious whether it was technically correct or not. Taking a break from network engineering, here goes a post about it.

Yesterday there was an article in the Indian paper Financial Express with the title “OTTs may have to pay access charge to telcos”.

Quoting a few points from the article:

• Social media intermediaries like WhatsApp, Facebook and Twitter, and over-the-top (OTT) players like Netflix, Prime Video and Disney+Hotstar may have to pay a carriage charge to telecom service providers
• Data, particularly video, comprises 70% of the overall traffic flow on telecom networks, and this would grow further with the rollout of 5G services
• Upon reference from the DoT, Trai is currently studying various possible models under which OTTs can be brought within the purview of some form of regulation
• According to sources, an interconnect regime is a must between OTTs and telcos because as 5G services grow, there would be immense data/ video load on networks, which may lead to them getting clogged or even crashing at times.

This concept of “OTTs must pay” is not new. This has been argued a few times in past. Exactly ten years ago in 2012 I wrote a blog post about Bharti Airtel expecting Google/YouTube to pay. At that time they could not convince OTTs to pay. Why is this renewed interest now? Well, that has to do with the first SK Telecom (South Kore telecom) Vs Netflix court case in South Korea where SK Telecom claimed that a large part of bandwidth utilization was because of Netflix and hence they should pay a “fair share” of their traffic which they lost. Soon around this multiple of large telecom monopolies in Europe started this discussion in their respective geography. Four of the top EU players - Deutsche Telekom, Orange, Vodafone and Telefonica are of opinion that OTTs should share the burden (news here). And hence Indian telcos possibly looking to renew this debate.

In Hyderabad for the weekend to participate in GFCE workshop at IIIT Hyderabad. I like GFCE workshops as they are short & to the point. This will be my third one after Delhi and Kolkata. These are round table discussions covering concepts like IPv6, routing security, DNS, email security protocols etc. I will be sharing updates on RPKI in the region and participating in the discussion about this wide varieties of topics.

Upcoming presentations

Next week will be APNIC 54 conference followed by SGNOG 9 (Singapore Network Operators Group) event. I will be attending both events. At APNIC 54 I will be doing a short tutorial on “Running Containers in Production” with CI/CD pipelines with a focus on its utility in network engineering and also a panel discussion on “World IPv6 2022 - the story behind the events”. This should be fun!
