designating a first portion of the inroute frame as a Transaction Reservation portion; and
designating a second portion of the inroute frame as an Aloha portion;
requesting, in the event a Transaction Reservation portion is to be communicated from a first of the plurality of remote terminals, that the host terminal allocate one or more slots of the Transaction Reservation portion to the first of the plurality of remote terminals;
redesignating one or more unallocated slots within the Transaction Reservation portion as extra Aloha slots; and

Abstract
An method of Aloha optimization involves designating a time period as an inroute frame. Such designating includes designating a first portion of the inroute frame as a Transaction Reservation portion, and designating a second portion of the inroute frame as an Aloha portion. A request is transmitted from a first remote terminal to the host terminal that the host terminal allocate one or more slots of the Transaction Reservation portion to the first remote terminal. One or more unallocated slots within the Transaction Reservation portion are then redesignated as extra Aloha slots. A target slot is then randomly selected by a second remote terminal from the slots within the Aloha portion and the extra Aloha slots.
