without Token Bucket Algorithm

oudmaster

hi,

to some extent I do understand token bucket algorithm used for QoS shaping,

but what could happen if shaping is configured and there was no such algorithm !!

cannot the interface manage itself without the idea of bucket ?

A bucket is just an explanatory representation of a small pool of memory that is allocated to an interface (a buffer). The concept of a token simply represents the fact that you cannot queue a packet in that memory if there is no available memory to store the packet. Fancier algorithms (colors and multi-tokens) are just methods of allowing configurable actions beyond certain thresholds (running out of memory).

In short, no. Without a bucket (memory), you just pass packets as they come (FIFO).
