Re: [Detnet] Terminology: queuing vs. scheduling

["Pascal Thubert (pthubert)" <[e-mail]>]

Hello Toerless

In my book queueing is about retention and scheduling is about a timely forwarding operation. But what you're looking for is about constrained as opposed to timely, meaning that scheduling is closer but too restrictive. 

All the best
