[ns] Max HSDPA throughput EURANE

> Hi everybody,

>> After some time working with EURANE I've found these non reported
>> mistakes:
>>
>> 1) UMTS/RLC/UMHS win_ parameter is useles. Nevermind its value,
>> nothing happens. By the way, at file ns-default.tcl it is set to 4095 but
>> in EURANE User Guide it is said to be set to 1024.
>> 2) parameter hs_downlinkBW for node configurations -UmtsNodeType bs
>> and -llType UMTS/RLC/ is useless. Nevermind its value, nothing happens.
>> 3) why the number of HARQ processes is set to 6? In any UMTS Release
>> 5 specification, is always set to 8. Also, at Deliverable D32.v2 this
>> parameter is said to be set to 8.
>> 4) Nowhere in EURANE documentation there is any reference to the UEs
>> categories used in the simulation. I guess some UE categorie is taken by
>> default, but don't know.
>> 5) There is no way to set more than 1 flow per UE if any of the flow
>> is a TCP type one. Only 2 CBR flow types per UE can work properly. Any
>> other combination mess up the bandwith.
>> 6) CBR can not be set to more than 3UEs (AM or UM mode, doesn't
>> matter).

>> 7) CBR maximum data rate per UE is 2300 Kbps, but setting
>> UMTS/RLC/UMHS credit_allo_interval parameter to 8 or "8ms" then thoughput
>> can be as high as 2800 Kbps/UE. Of course this is a very unstable setting
>> and easily leads to "Couldn't schedule timer" errors. By the way, at file
>> ns-default.tcl this parameter is set to 15 but in EURANE User Guide it is
>> said to be set to 30ms.
>> 8) TCP maximum data rate per UE is 330 Kbps.
>>
>> HSDPA maximum theoretical data rate is 14.4 Mbps !!!
