A dynamic bandwidth assignment algorithm for B-PON

摘要

To transport TCP/IP data efficiently through B-PON (Broadband Passive Optical Network), the DBA (Dynamic Bandwidth Assignment) function has been studied widely as well as in FSAN, and is in the process of being standardized in ITU-T. This paper proposes an effective algorithm for implementing the DBA function for B-PON. The proposed algorithm allows for a quick response to data input to the ONT, fairness of bandwidth assignment and CDV within the tolerable value. This paper also evaluates the proposed algorithm using a computer simulation.
