Flow
The state of packet flow control for this PPTP session:
Local = the local buffer is full; i.e., packet flow for the local end of the session is OFF because the
number of outstanding unacknowledged packets received from the peer is equal to the local window
size.
Peer = the peer buffer is full; i.e., packet flow for the peer end of the session is OFF because the
number of outstanding unacknowledged packets sent to the peer is equal to the peer’s window size.
Both = both buffers are full; i.e., packet flow for both ends of the session is OFF because the
number of outstanding unacknowledged packets is equal to the window size on both ends.
None = Neither end of the session has a full buffer; i.e., packet flow for the session is ON. This is
the normal operating state.
