Fixed-Filter (FF) Style

Fixed-Filter (FF) Style

Fixed-filter reservations have distinct reservations with explicit sender selection. For each FF reservation established, the router must allocate bandwidth for each request. The total bandwidth allocated is the sum of the bandwidths requested by each FF request for a distinct source. If two or more receivers request a resource and specify the same sender, the allocated resource will be shared by the receivers for that sender. The FF style can be represented by

FF(S{Q})

where S is the specific sender and Q is the flowspec. The FF style is contained in Figure 10-5 with the total bandwidth allocations shown in Table 10-3.
