“…With the concept of splitting, the problem of bandwidths wastage of links upstream from the token-holding node can be significantly eliminated. Later, a scheme for throughput improvement in multi-splitting lighttrails was investigated [8] and a delay-aware MAC protocol based on multi-splitting concept was proposed [7]. Pal and Ranade [24] gave polynomial time algorithms for both static and dynamic scheduling problems in ring networks.…”

“…1 Light-trail node architecture and an example of three-node light-trail [7] past, e.g., Delay Sensitive Smoothed Round Robin (DS2R2) algorithm in [1] and Dual Auction protocol in [13]. As DS2R2 is designed for constant traffic instead of bursty traffic, which is the traffic type this work discussed, only Dual Auction protocol is considered in this work.…”

“…Afterward, many variations of lighttrail architecture were proposed as well, such as bidirectional light-trail (BDLT) [22], strongly connected light-trail (SLiT) [11], waveband switching light-trail (WBS-LT) [27], and multicast-capable light-trails [12]. In addition to architecture design and MAC protocol proposals [3][4][5][6][7][8]17,24], there are other interesting issues like the routing problem and DBA problem [21]. The routing problem is an extensively investigated one in light-trails, e.g., the static routing problem [2,3,23,26,30], the dynamic routing problem [14,19,[28][29][30].…”

Light-trail, a framework proposed in the past few years, is generalized from the concept of lightpath, and its distinguishing features include bandwidth sharing and efficient bandwidth utilization. Performance of light-trail networks depends on the routing algorithm and the dynamic bandwidth allocation (DBA) scheme, and the former issue has been discussed extensively. In this work, we aim at the design of an efficient DBA scheme, named Demand and Delay-latency Aware with Two-round Deliberation (D 2 ATD), to allocate bandwidth more accurately and efficiently in light-trail networks. In addition to DBA issue, D 2 ATD includes a light-trail setup/release mechanism as well. As expected, the simulation results reveal superiority of D 2 ATD in both blocking performance and delay performance. Although D 2 ATD pays This paper is an extension of our previous work published in Proc. Int. Conf. on Network-Based Information Systems (NBiS), 2010. The following is the list of the major differences between the previous paper and the current submission: (1) The current submission gives a more detailed survey of previous work and much more figures, tables, and relevant discussions.(2) The current submission refines and makes elaborate explanation of the proposed scheme and formulates light-trail setup/release operations in the algorithmic pseudo code form.(3) The current submission assesses the proposed scheme under four scenarios which are combinations of different settings of packet sizes and the ratio among three service types. Discussions in our NBiS paper are based on one scenario only. (4) The NBiS work merely evaluates performance gain resulting from the proposed DBA algorithm while the current submission discusses the overall effect brought by the proposed DBA algorithm and the proposed light-trail setup/release mechanism in addition. The current submission includes more references relevant to light-trails as compared with our NBiS paper.B Ching-Fang Hsu a price of control overhead for performance gain, it is still reasonable since the amount of control messages does not exceed the capacity of the control channel. It verifies that D 2 ATD can properly employ the control channel to achieve excellent performance.
