Abstract--- In the current Internet, many applications start
sessions with multiple connections to multiple servers in order
to expedite the reception of data. One may argue that such
aggressive behavior leads to unfair sharing of bandwidth using
the current per­connection rate allocation methods. Sessions with
more connections get a higher total rate than competing sessions
with fewer connections. In this paper, we explore the issue of
fairness of rate allocation from a session point of view. We define
a multipoint­to­point session as a set of point­to­point connections
started from multiple servers to a client in order to transfer an
application­level object. We present session fairness definitions,
propose algorithms to achieve these definitions, and compare
the resulting allocations with the traditional connection fair
algorithm. It is clear from our evaluations that the session fair
algorithms proposed achieve a more fair distribution of session
