“…This aspect requires a unique node design for light-trail technology. In the work done so far on light-trails [1][2][3][4][5][6][7][8][9][10][11][12][13][14] to the best of our knowledge the node design has not been considered in detail. We, in this paper delve upon this aspect of light-trail technology.…”

“…Such a topology of light-trails over a network exemplifies a virtual embedded topology. Optimal light-trail topology design is an important issue under investigation [11][12][13]. Further, dynamic schemes for light-trail design lead to a selfoptimizing virtual topology [2].…”

“…However the requirement of OEO conversion and regeneration at every node along a path means that such network deployments are expensive and are protocol/line-rate dependent. The lighttrail solution proposed in [1][2][3][4][5][6][7][8][9][10][11][12][13][14], serves as a new mechanism for optical layer traffic grooming. A light-trail is defined as a generalization of a lightpath such that multiple nodes can take part in communication along the path.…”

A light-trail is a generalization of a lightpath such that multiple nodes can take part in communication along the path. A light-trail is a good candidate for optical layer traffic grooming. In this paper we investigate the grooming aspect of light-trails from a sub-system perspective. We introduce a new sub-system called burstponder card that enables efficient grooming of traffic in a light-trail. We describe the implementation of the burstponder card using FPGA and burst-mode optics. We show experiment results on efficiency and latency for a 4-node light-trail network demonstrating it as an effective solution for optical grooming.

“…Note that while in light-trails the optimization is considered over the entire bus (i.e. the capacity constraints take the entire bus bandwidth into consideration) [7], in LiTPiCs the optimization takes a per-span value into consideration. This deviation is necessary to take into consideration the formation of PIC-Trails, as PIC-Trails can divide a LiTPiC into several buses.…”

“…Hence, a node i part of LiTPiC k continues to monitor the bidding process in LiTPiC k', if k' is of interest to node i. LiTPiC k' is of interest to node i if (a) k' contains all destination nodes that node i is interested in transmitting data to, and (b) the total value of traffic in k' can accommodate additional traffic from i, if node i so chooses to become a member of k'. The deciding point that determines when node i should leave LiTPiC k for k' (though it still continues to be a passive [7] member of k -without transmitting or bidding for bandwidth in k) is:…”

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.
