MAGELLAN-1 - Getting issue details... STATUS
There is something old school about knowing exactly where your packets are on the surface or below the ocean of the earth.
I know this might sound weird but not to someone who lives science as a normal part each day. I would like to make sure my REST calls propagate around the globe - not just to a server on the other side of the earth and back again like from us-east-1 to the Singapore ap-southeast-1 region but through us-west-2 through singapore - to europe and back to us-east-1.
Sort of when I fly - in order to maximize the number of takeoffs and landings - I try to get the most number of stops - a direct flight is not the best way to get somewhere when testing latency - as in packets on the cable from Oregon to China are better routed through Hawaii.
I liked Andrew Blum's "Tubes" book - which include details on the endpoints for sub-marine cables - https://www.amazon.com/Tubes-Journey-Internet-Andrew-Blum/dp/0061994952 - I also ran into a bit of this propagation delay working at Nokia.
This system will of course run a set of helm/kubernetes clusters (a cluster of 1 on each DC for now)
First principles will be install proxies at several regions in Amazon EC2 - https://aws.amazon.com/about-aws/global-infrastructure/
see https://www.submarinecablemap.com/
This is the path we will take (see the red circles on the Amazon AWS regions) - hopefully no backtracking and ideally it is roughly valid - as we do not actually cross the equator - I will also try through Sau Paulo.
through the following Amazon regions

Base Cases
Opposite sides of the earth - Singapore - ap-southeast-1 to New York - us-east-1
It will never be shorter that 160 ms - which is c/(radius * pi /2) = as it it takes 16% of a second for light to pass to the other side (this is without optical repeater and endpoint delays)

Architecture
Conceptual Architecture
Path Propagation
All paths are linear in sequence with the first bit reserved for off axis secondary routes. For example 00 is us-east and 10 is us-east but 01 is ca-central (north of us-east).

WI 1: Reflection Rest API
API is a simple reflection REST call that accepts a forwarding address (that may be the source address) from which we can configure any type of ring, tree topology.
Testing
Packet Reflection between 2 local systems
Packet Reflection between opposite sides of the Earth
us-east-1 in Virginia
ap-southeast-1 Singapore
Build/push the docker image to obrienlabs/magellan
Run the docker image in both endpoint servers
# on remote server docker pull obrienlabs/magellan-nbi:0.0.2 docker run --name magellan-nbi -d -p 8080:8080 obrienlabs/magellan-nbi:0.0.2 docker logs -f magellan-nbi # on local server docker pull obrienlabs/magellan-nbi:0.0.2 docker run --name magellan-nbi -d -p 8080:8080 obrienlabs/magellan-nbi:0.0.2 docker logs -f magellan-nbi check health curl http://localhost:8080/nbi/api

Testing Results
A round trip between Singapore and Virgina and back to Singapore is 2021-09-26 04:39:52.116 - 2021-09-26 04:39:51.475 = 0.116 + (1 - .475) = .116 + .475 = .691 sec = 2 x 345 ms each way (packets may have followed different routes - or even in the same direction. Next experiment is to increase the hops to force the packets to round the earth and not follow the same return path
how much of this is the "pure speed of light" - or the minimum lag time = 7927 * 3.141 = 24900km (both halves), therefore 24900/299792 = 80 ms (there is propagation delay in relay and 10gbe fiber/copper translation.
2nd run after optimizing the Java 11 HttpClient is 210ms round trip
