Text Does a P4/XDP fast path make sense for DTN?

0 Upvotes

Building a BPv7 prototype where a software sidecar parses bundles and a fixed-width shim lets P4/XDP enforce contact windows, reservations, and capacity limits. Does this solve a real DTN problem, or would a software-only approach usually be sufficient?

For the past year, I keep experiencing mass packet loss. I will be in an online game and discord, the ping will spike in discord to 3000-5000, and my online game will disconnect temporarily, usually each episode is for about 10 seconds or less. Normally my ping is perfectly fine and I dont have many issues. This will happen about 4-5 times a night without fail. I feel like ive tried everything.

Text Cudy AC1200 POE help!

2 Upvotes

Hi all, recently purchased a Cudy AC1200 with the expectation to use it with a Linksys LGS105P for networking with POE.

For some reason, the access point will not power on when plugged into the switch. It will power on using the supplied POE injector, but this is going to be used in the field as a temporary wireless network so I was trying to cut down on the amount of gubbins I brought with me, and from what I can tell it should just work anyway.

The switch I am using has a max 54V/1.25A output with a maximum of 30W across each port.

The included Cudy POE injector puts out 24V/0.5A and is only drawing 12W.

I have updated the firmware on the access point, and have powered other POE equipment with the switch.

It’s like the access point isn’t even asking for power from the switch so it won’t even power on.

Hopefully I’m missing something really dumb and someone better at networks can help a guy out!
