End of 2017 hurricane season
by Sean Donelan 23 Jan '18

23 Jan '18

November 30 is the official end of hurricane season in North America. Puerto Rico's Internet routing announcements are 95% of pre-Maria levels. US Virgin Islands Internet routing announcements are 80% of pre-Maria levels. The #(provider name)sucks tweets on twitter in South Florida and South Texas have essentially stopped. I assume this means that providers have repaired almost all Hurricane Harvey and Hurricane Irma damage.

Blockchain and Networking
by Glen Kent 23 Jan '18

23 Jan '18

Hi, Do folks on this list see blockchain technology making inroads into the networking? I can see blockchain being used to secure the SDN environment where blockchain will allow encrypted data transfers between nodes (ones hosting different applications, the SDN controller, the data plane devices) regardless of the network size or its geographical distribution. Where else can blockchain be used in networking? Glen.

by Dovid Bender 20 Jan '18

20 Jan '18

Hi, N00b here trying to understand why certain CDN's such as Cloudfare have issues where my MTU is low. For instance if I am using pptp and the MTU is at 1300 it wont work. If I increase to 1478 it may or may not work. TIA.

China is beefing up filtering measures
by Youssef Bengelloun-Zahr 19 Jan '18

19 Jan '18

Dear Nanogers, By now, I'm pretty that the community has heard that china is planning to increase (once again) filtering measures by limiting ports 80 / 443 / 8080 : https://www.reddit.com/r/China/comments/7opv4f/china_to_block_sdwan_and_vpn… https://www.goldenfrog.com/blog/article-claims-china-block-vpns-causing-con… https://www.sd-wan-experts.com/blog/china-stops-sd-wans-cold-register/ https://www.networkworld.com/article/3247705/sd-wan/will-china-start-blocki… I've been doing some googling (read above) and I have come to the following conclusions : - Only clear thing is that a "commercial" ISP can register with CN gov to lift that filtering ? - This should be enforced by Feb, 1st. - Pretty much all the rest is unclear when it comes to the : who ? what ? how ? I'm trying to understand exactly what we might be dealing with here. Do anyone happen to have a clear view on this ? Are some of you already affected by this ? Thank you for your feedbacks. Best regards.

Re: MTU to CDN's
by Michael Crapse 19 Jan '18

19 Jan '18

I don't mind letting the client premises routers break down 9000 byte packets. My ISP controls end to end connectivity. 80% of people even let our techs change settings on their computer, this would allow me to give ~5% increase in speeds, and less network congestion for end users for a one time $60 service many people would want. It's also where the internet should be heading... Not to beat a dead horse(re:ipv6 ) but why hasn't the entire internet just moved to 9000(or 9600 L2) byte MTU? It was created for the jump to gigabit... That's 4 orders of magnitude ago. The internet backbone shouldn't be shuffling around 1500byte packets at 1tbps. That means if you want to layer 3 that data, you need a router capable of more than half a billion packets/s forwarding capacity. On the other hand, with even just a 9000 byte MTU, TCP/IP overhead is reduced 6 fold, and forwarding capacity needs just 100 or so mpps capacity. Routers that forward at that rate are found for less than $2k.

How do i remotely connect to an ix? In the en. speaking caribbean we have probably six to eight small national ixps. I want to be present at all of them, & its been suggested i can make some cost savings by remote connection using mpls. Is this a viable option? Is there a disadvantage in doing this? Thx. Rudi
