How is our speed (~605km/s) derived from the CMB dipole anisotropy?

It is derived from the CMB redshift taken in multiple direction. Subtracting the highest from lowest redshift gives a differential of about 600 kms.
Thanks. How then is velocity derived from Red Shift exactly? Are certain speed associated with certain changes in frequency? Is it linear or does it follow the lorentz factor curve?
