CSR1000v + ASR1000 Code Upgrade Pleasure...
by Mark Tinka 13 Oct '21

13 Oct '21

Hi all. I thought I'd share our recent experiences, per subject, just in case others run into the same problems. So... we finally decided to try 17.3(4a)MD for the CSR1000v, after years of happy operation. Good Lord, what a drama! At first, we couldn't figure out why iBGP sessions to all Cisco boxes could not stand up. Then we realized it's because IS-IS to them could not stand up. Then we realized it's because BFD sessions could not stand up. But even after removing BFD, IS-IS remained down. After 3 days of searching, we finally landed on CSCuz58508. In case you don't have CCO access, it is the same issue as described here: https://community.cisco.com/t5/cisco-cloud-service-router-csr/b00ocg4q4e-cs… This was even more confusing for us, because our interface driver on VMware ESXi is vmxnet3. The bug ID suggests the problem is fixed in 16.3(2) and 16.4(1). So to be safe, we tested 16.12(5)MD, which allowed us to enable jumbo frames, but that only appeared to be a cosmetic thing. In the background, the box was simply dropping packets, silently. We found this out when we tried to copy other files to the node, and it would just hang without any feedback. Removing the jumbo frame support allowed the files to come through. We noticed that nodes still running 3.17(0)S did not have any issues with IS-IS or BFD, or MTU. However, this code was only ever released as an ED train (and to be fair, we've been having dodgy issues with it in recent years), so we decided to downgrade to 3.16(9)S (which is actually an upgrade from 3.17(00)S, since the 3.16 train is an MD release, with the latest release being March 2019, vs. July 2017 for 3.17(4)SED). With that, no more MTU issues, BFD and IS-IS are happy, iBGP is happy. We definitely won't be wasting any more time trying to make Denali, Gibraltar, Fuji, Everest or Amsterdam work on our CSR1000v complement. Needless to say, moving the ASR1000 platform to 17.3 has also come with its own avenue of pleasure, what with all the ROMMON, CPLD and FPGA upgrade mess that is. What the documentation says and what happens in real life are two very different things. It has taken us a week to come up with our own working procedure to upgrade just one box, worse if it's a dual-RP system. Mark.

Linux WiFi Package Issues
by Pascal Masha 12 Oct '21

12 Oct '21

Hello All, I have been wondering whether there is any known issue with the Linux WiFi package since the last 3 days or so? I'm Ubuntu 20.04.3 LTS 64bit Distro and WiFi has been dropping almost every 5 minutes. A colleague on another Linux Disto also contacted me about the same thing. Has anyone in the community experienced the same issue? Regards Paschal Masha

That's not how it works. Several streaming BitTorrent clients specifically request blocks in order so that you can start watching immediately. Not that you need a special client, it works pretty well with the standard client as well on a well seeded torrent, as blocks are generally requested more or less in order. > It also assumes the device has all the necessary apps > and codecs needed to render the file. Well, yes.

They could, and they might even have, I forget, but there is little demand for such a thing as a centralized CDN strategy works better. > But I doubt that > will work, unless someone can think up a clever way to modify BitTorrent > to suit today's network architectures. Unless network topology is somehow exposed, this isn't possible. All anybody can do is use latency, IP and ASN information as a proxy. Nothing is stopping a BitTorrent client from being selective about its peers. The current peer selection algorithm optimizes for throughput, not adjecency or topology. - Jared

Doug Barton wrote: > One incentive I haven't seen anyone mention is that ISPs don't want to > charge customers what it really costs to provide them access. For the sake of argument, let's assume this is true. For this to work, I am really trying hard to ignore inconvenient facts like: "South Korea’s SK Telecom (SKT) has reported operating revenues of KRW4.818 trillion (USD4.2 billion) for the quarter ended 30 June 2021, up 4.7% year-on-year, with it saying that the increase was ‘due to continued solid growth trends in all business areas’. SKT’s operating income in Q2 2021 totalled KRW397 billion, up 10.8% on an annualised basis..." https://www.commsupdate.com/articles/2021/08/12/sk-telecom-reports-revenue-… Nevertheless, let's go with the hypothesis that service is provided below cost. Providing access is mostly fixed costs, as there are very few consumables in running a network. IP transit costs aren't an issue, since Netflix will do settlement free peering. This leaves the internal network of SK Telecom as the problem and cost center. There would have been no marginal cost if SK Telecom's own network was capable of handling the traffic of its customers. So basically SK Telecom is mad at Netflix for forcing equipment upgrades faster than budgeted. Should Netflix have to pay for SK Telecom sucking at traffic planning and budgeting? - Jared

Since we aren't talking about random pirated content, but p2p streaming from a major content provider it would obviously be point & click. - Jared

What Eyeballs Did During The Facebook Nap
by Mark Tinka 08 Oct '21

08 Oct '21

So we are reviewing our flow data, and it's very clear, on our network, that during the period Facebook were experiencing their global outage, Netflix traffic went up 3X for us. The psychological assessment of this, for me, is most interesting; especially because like carbohydrates, social media addiction does not create "medically immediate" mental harm, unlike other addictions such as cocaine, heroine, crystal meth, LSD, alcohol, e.t.c., which governments and the medical fraternity are quick to label as "dangerous to human health due to their addictive properties". Could Netflix, perhaps, play a part in mitigating the increasing impact of social media addiction in teenagers, whose young brains aren't developed enough to have sufficient executive control, impulse control and good judgement? In the words of Spock, "Fascinating!" Mark.
