...The first such implementation, the GIANT DBA [10], was published in 2006, benchmarking QoS based DBA implementation for GPON....
[...]
...A down counter (service timer in [10]) kept track of each T-CONT type’s SI; the expiry of each service timer invoked the allocation of AB for the corresponding T-CONT....
[...]
...It had the following fixed mapping between the classes of traffic and traffic container (TCONT) types in its implementation: • T-CONT T1 : fixed bandwidth only • T-CONT T2 : assured bandwidth only • T-CONT T3 : assured & non-assured bandwidth • T-CONT T4 : best-effort bandwidth only Each T-CONT was given a higher size of US data (allocation bytes or AB in [10]) to be transferred at a fixed interval (service interval or SI in [10], equivalent to integer multiples of the periodicity of a single US frame in GPON)....

...We did not use T1 traffic flow in any experiment as T1 has a fixed allocation in GIANT [10]....

...The ITU compliant DBA schemes like GIANT [62] and its improved versions [20,63,64] have a fixed polling cycle period defined in terms of number of DS or US cycles termed as service interval (SI)....

...The frame size follows the tri-modal distribution [12], where the frame sizes are 64, 500, and 1500 bytes and their load fractions are 60%, 20% and 20%, respectively as in [6]....

...The protocol overhead introduced by ATM for segmenting and transporting large variable-length IP packets into fixed-size 53-byte cells is considered an increased waste of resources (also called ‘cell tax’) and can reach levels above 10% [3]....

...APONs present the following disadvantages compared to Ethernet PONs (EPONs): higher protocol overhead, lower bandwidth, increased costs and not straightforward integration of LANs into future optical Ethernet-based WANs [3, 4]....
[...]
...The overall efficiency of EPON is also considered higher compared to APON not only because of the higher bit rate (1Gb/s versus 155/622Mb/s) but most important because ATM did not live up to its promise of becoming an inexpensive technology, whereas the large numbers of Ethernet component and system vendors and manufacturing volumes make economics more favourable and integration of LANs transparent for Ethernet-based WANs [5]....

...The algorithm used by the MAC controller presented in this paper has been initially outlined in Reference [10] and is presented in Section 2 in a rigorous manner, probing further on system level design and hardware/software partitioning issues....

...To this end, the MAC protocol as executor of the TDMA multiplexing in the upstream of the PON is of prime importance for cost effectiveness, fairness, traffic profile control and QoS guarantees [7, 8]....

...It adopts fixed periodic framing accommodating TDM and ATM needs, so that services with very strict requirements can be serviced at the right moment, temporarily interrupting data packets, hence the need for fragmentation [7]....
