“…In general, capacity analyses of WDM ring networks have primarily focused on unicast traffic [18,19]. In contrast, we consider multicast (multidestination) traffic, which poses a number of unique challenges in WDM ring networks [20][21][22][23] and has begun to receive significant interest in optical metropolitan area networks [24,25].…”

͑Doc. ID 75837͒ The recently approved IEEE 802.17 Resilient Packet Ring (RPR) network deteriorates under multicast traffic to legacy ring technologies that do not support spatial reuse. We extend our multicast approach with spatial reuse from a currently single-channel RPR to WDM-upgraded multichannel RPR networks, where each node can transmit packets on all wavelengths and receive on one wavelength, and analyze their multicast capacity. Our analysis provides a convenient method for evaluating the multicast and reception capacities of WDM-upgraded RPR networks for a wide range of uniform unicast, multicast, and broadcast traffic scenarios.

“…The photonics level issues involved in multicasting over ring WDM networks are explored in [18], while a node architecture suitable for multicasting is studied in [19]. The general network architecture and MAC protocol issues arising from multicasting in packetswitched WDM ring networks are addressed in [16], [20]. The fairness issues arising when transmitting a mix of unicast and multicast traffic in a ring WDM network are examined in [21].…”

Abstract-In this paper we examine the relationship between the effective capacity (stability limit) of unidirectional and bidirectional packet-switched wavelength division multiplexing (WDM) ring networks for multicast traffic. We consider both bidirectional rings with one packet copy transmission per wavelength channel and two packet copy transmissions. We first prove bounds for the ratio of the multicast capacity of the bidirectional ring to the multicast capacity of the unidirectional ring. Specifically, we show that this ratio is at least two for two copy transmission in the bidirectional ring, and at most two for one copy transmission. We derive closed form expressions of the multicast capacity ratios for networks with a large number of nodes and from these expressions show that the ratios tend to two for a large number of multicast destinations. We demonstrate that for the bidirectional ring with two copy transmission the ratio becomes as large as 2.276. We also find that in the bidirectional ring, the capacity gain with two copy transmission over one copy transmission reaches 30.4%.

“…The general network architecture and MAC protocol issues arising from mul-ticasting in packet-switched WDM ring networks are addressed in Refs. [13,14]. These studies do not address the fairness issues arising from transmitting a mix of unicast and multicast traffic over a WDM ring network, which is the main focus of this paper.…”

“…The LQ-C selection achieves load balancing among the queues in the system, i.e., it strives to keep δ u [expression (12)] and δ m [expression (13)] small and at the same time strives to maximize the transmitter/receiver throughputs. The UC/MC buffer selection, on the other hand, strives to keep δ u/m [expression (14)] small; i.e., to enforce fairness between unicast and multicast traffic.…”

Fair uni- and multicasting in a ring metro WDM network

Packet-switched wavelength-division multiplexing (WDM) ring networks have been extensively studied as solutions to the increasing amount of traffic in metropolitan area networks, which is widely expected to be a mix of unicast and multicast traffic. We study the fairness between unicasting and multicasting in slotted packet-switched WDM ring networks that employ a tunable transmitter and fixed tuned receiver at each node and a posteriori buffer selection. We find that single-step longest-queue (LQ) buffer selection generally results in unfairness between unicasting and multicasting or a fixed relative priority for multicast versus unicast traffic. We propose and evaluate dual-step buffer selection policies that achieve fairness and allow for a range of relative priorities of multicast versus unicast traffic.
