It sounds like you’re looking for a way to convert MCR (typically Minimum Cell Rate in networking/ATM) to MCD (less standard; possibly Minimum Cell Delay , Maximum Cell Delay , or a typo for MCR to MCD in a specific hardware context like traffic shaping).
However, given the phrasing “mcr to mcd converter” is uncommon, here are the two most likely interpretations and how to handle each:
1. ATM Traffic Parameters (MCR → MCD ratio for buffer sizing)
In ATM (Asynchronous Transfer Mode) networks:
MCR = Minimum Cell Rate (cells/sec)
MCD = Maximum Cell Delay (sometimes used in ITU standards, e.g., I.371)
There is no direct formula because MCD depends on:
Peak Cell Rate (PCR)
Sustained Cell Rate (SCR)
Maximum Burst Size (MBS)
Buffer size at switch
Practical guide (if configuring a policer/shaper):
MCR sets a guaranteed floor.
MCD = (Buffer capacity in cells) / MCR (worst-case delay, but only if no higher-priority traffic).
More realistically: MCD ≈ (Burst_Tolerance + Buffer) / MCR
👉 No standalone converter exists ; you need the network’s buffer and service curve.
2. Typo: Did you mean MCR to MBR or MCR to CDVT ?
CDVT = Cell Delay Variation Tolerance (in µs)
MBR = Maximum Burst Rate
If you actually need MCR to CDVT :
CDVT (cells) = MCR (cells/sec) × Tolerance_time (sec)
Example: MCR = 1000 cells/sec, tolerance = 10 ms → CDVT = 10 cells.
