Customer: I am facing packet loss
Me: I am sorry to hear that. Can I get your circuit ID please
Me: Sir, I see that you are using ~490kbps on a 512kbps link. Hmm..you are going to have some packet loss depending on your usage.
Customer: What!!! You think I don’t know anything. I have been in this business for 8 years. I have tens of links. The other provider never has problems. You are shaving me off on 10kbps.
Me: ?? ?? ??
love being the helpdesk monkey :).
Moral: Doesn’t anyone know that “raw datarate, doesn’t take into account data framing or encoding” of the TCP/IP stack.
