Australia has proposed for definition in ITU Recommendation 1.371 an ATM layer capability based on controlled transfer of cells, or the Controlled Cell Transfer (CCT) capability. This transfer capability will be in addition to four other ATM layer transfer capabilities (DBR, SBR, ABT and ABR). already in the draft recommendation. In contrast to the other capabilities, CCT will permit loss-free multiplexing of data applications, giving possibility of LAN-like services over the wide area. An ATM switch supporting the CCT and DBR capabilities has been designed and simulated by ATRI. Simulations of network response for bursty data traffic show that, for a given dedicated network capacity, CCT generally results in more than an order of magnitude shorter transfer delay for messages and files than one obtains with DBR, and might be expected with the other capabilities. To highlight this fact, other simulation studies performed on the ABT capability, CCT and DBR capabilities are also presented. The paper briefly discusses the CCT capability, as proposed to ITU. It also discusses the switch implementation ami simulation results obtained.
