Re: [ Brighthouse] Slowdowns in Tampa Bay???
Last Monday evening packet loss was around 90% (I gave up and watched TV..), but as of Tuesday the packet loss has totally stopped. Peak time speeds are running about 350 kbits/sec, which is *flying* compared to before. Web browsing has improved tremendously. Nothing times out and generally feels quick.
Can a network guru here answer a question:
What causes packet loss when a node is overloaded? It is because the headend router on the node doesn't have sufficient memory to buffer the requests? Think they added memory to the router on my node? |

| Found the answer on Cisco's site:
"A common scenario for packet loss is when an output queue is full of packets to be transmitted where there is no additional memory space for additional ingress packets; this condition is commonly referred to as an output queue full condition. In this condition, the network device that is queuing the packets has no choice but to drop the packet. For example, an output queue full condition can occur where a sender attached to an interface of a higher speed is sending to a receiver attached to an interface of a lower speed. Eventually, the output queue buffers become full, resulting in dropped packets."

I don't know if that's what was happening, but I'd bet it was, and some nice Brighthouse tech saw my post and investigated (Thank you!). |
