I'm not the best RRD writer, but I'm guessing you could do something along the lines of subtracting your known bandwidth from the total bandwidth to get the bandwidth of the unknown customer.
Something along the lines of: #define upstream and known customer datapoints DEF:UPSTREAM_In-raw=/PATHTOZENOSSRRD/ROUTER/os/interfaces/INTERFACE/ifHCInOctets_ifHCInOctets.rrd:ds0:AVERAGE DEF:UPSTREAM_OUT-raw=/PATHTOZENOSSRRD/ROUTER/os/interfaces/INTERFACE/ifHCInOctets_ifHCOutOctets.rrd:ds0:AVERAGE DEF:Customer1_In-raw=/PATHTOZENOSSRRD/CUSTOMER1_ROUTER/os/interfaces/INTERFACE/ifHCInOctets_ifHCInOctets.rrd:ds0:AVERAGE DEF:Customer1_OUT-raw=/PATHTOZENOSSRRD/CUSTOMER1_ROUTER/os/interfaces/INTERFACE/ifHCInOctets_ifHCOutOctets.rrd:ds0:AVERAGE CDEF:UPSTREAM_In-rpn=UPSTREAM_In-raw,8,* CDEF:UPSTREAM_Out-rpn=UPSTREAM_Out-raw,8,* CDEF:Customer1_In-rpn=Customer1_In-raw,8,* CDEF:Customer1_Out-rpn=Customer1_Out-raw,8,* CDEF:Customer2_In-raw=UPSTREAM_In-raw,Customer1_In-raw,- CDEF:Customer2_Out-raw=UPSTREAM_Out-raw,Customer1_In-raw,- CDEF:Customer2_In-rpn=Customer2_In-raw,8,* CDEF:Customer2_Out-rpn=Customer2_Out-raw,8,* Then plotting your rrd similar to the graphs posted above. I would caution you to NOT use this for billing information as these are calculated values and not actual traffic flowing across the customer's device.
