Re: [STDS-802-16-MOBILE] CID -to- SFID mapping



You bring back a very, very old argument. Research the archives of this listservice and you will find it many times, I am sure. Your opinion is very valid. However, there are some equally, perhaps even slightly more compelling reasons in favor of the strategy adopted in the standard (this is not unique to the 16e mobility standard; this is intrinsic to the 802.16-2004 and previous iteration standards). But the point is mute; the issue decided. We struggled over this for over two years--and then revisited it on numerous occasions when individuals such as yourself again reminded us of the disadvantages. But the 802.16-2004 standard was approved for publication over a year ago, so I don't think we are going back there. You can always re-voice your disagreement during some future revision of the standard ;-)

Thanks for your response. This conforms my understanding. However, I do not know why standard went in this direction.

 

This is, clearly, in-efficient from MAC & overall system capacity perspective.

 

Am I missing some hidden strong rational for this design ?

 

Thanks,

Relationship between SFID and unicast transport CID is unitary (see 6.3.1.1 PMP, page 14, line 25, in P80216/Cor1D4 which states: 'When admitted or active, service flows are uniquely associated with transport connections.'). A unicast transport CID cannot have more than one SFID assigned to it. Note that I am distinguishing unicast CIDs from multicast CIDs (see Table 345 in P80216e/D10). Multicast CIDs can have multiple SFIDs assigned to them (in the downlink only, of course).

Hi,

 

Does standard allows multiple SFID of same flow-type (such as best-effort or nrt) to same CID ??

 

Thanks,
