Amitava..

Check this "ndd" parameters,

tcp_cwnd_initial - Initial size of the congestion window as a
tcp_recv_hiwater_def - Maximum receive window size
tcp_recv_hiwater_lfp - Maximum receive window size for fast links
tcp_recv_hiwater_lnp - Maximum receive window size for slow links
tcp_rwin_mss_multiplier - Multiplier applied to the receive window MSS


To get more detail of the parameter, check with ndd help,
Example:
=========
# ndd -h tcp_cwnd_initial
