Currently the bucket size is by default being computed based on the leak rate and the expected life time of LLC frames. The latter is either taken from 'queue lifetime' (if given) or a fixed value is used. Using 'queue lifetime' has the drawback that it sets a 'hard' limit, since frames will be dropped if they stay in the queue for a longer time. This commit adds a VTY command to specifically set the time used for the computation of the bucket size advertised to the SGSN. It does not affect the PCUs queue handling in any way. If the bucket time is not set (or if the 'no' command has been used), the old behaviour (see above) is applied. The following VTY commands are added (config-pcu node): - flow-control bucket-time <1-65534> Sets the time in centisecs - no flow-control bucket-time Don't use this time Ticket: OW#1432 Sponsored-by: On-Waves ehf |

This is an implementation of Packet Control Unit (PCU) according to TS 04.60 The PCU is part of BSS, so it connects directly to SGSN. == Current limitations == * No PFC support * No fixed allocation support * No extended dynamic allocation support * No unacknowledged mode operation * No PCCCH/PBCCH support * Only single slot assignment on uplink direction * No half-duplex class support (only semi-duplex) * No handover support * No measurement support * No TA loop * No power loop * No CS loop * No EGPRS
