Abstract--Recent demand for real time applications has given rise to a
need for Quality of Service (QoS) in the Internet. Differentiated Services
is one of such efforts currently pursued by IETF. Previous researchers
found unfairness in the DiffServ network. To solve the unfairness prob-
lem, we propose a new TSW based three color marker (ItswTCM) which
achieves proportional fair sharing of excess bandwidth among aggregates.
We have compared the fairness of our proposed ItswTCM marker with
srTCM, trTCM, and tswTCM. Results show that our proposed marker per-
forms better than the other three schemes for low to middle network pro-
