Hi Haoyu,

> As I recall, Kireeti only gave a few words claiming it’s easily implementable, while the other vendors (HW and Cisco) confirmed my analysis with their analysis documented in PPTs (specifically, the bitmap encoded ISD increases both parser size and parsing latency).


That was Kireeti’s summary of the discussions that he had with hardware folks. Bitmap encoding is not germane to the ISD discussion at hand.
