The arrayed-waveguide grating-based single-hop WDM network: an architecture for efficient multicasting

“…For all feasible scheduling patterns we calculate with the recursion (9) where if is feasible i.e., satisfies (5) and (6) otherwise. 10if is feasible i.e., satisfies (5) and 7otherwise.…”

“…Since the mid-1990s, multicasting over single-hop WDM networks based on the passive star coupler (PSC) has received considerable interest [9]- [23]. With the emergence of the metro gap, multicasting over PSC-based single-hop WDM networks has received renewed interest [24]- [31].…”

A Reservation-Based Multicast Protocol for WDM Optical Star Networks

“…Therefore, it is prudent to design a single MAC protocol which can deliver high throughput for both kinds of traffic. We strive to achieve the maximum theoretically possible throughput for unicast traffic with distributed control [11] and higher throughput than the existing MAC protocols with distributed control such as those reported in [1], [3], and [23]. With the above mentioned motivations in our mind, in this paper, we present a new reservation-based MAC protocol with multicast support.…”

“…broadcasts a data frame to all the optical links connected to it, the protocols presented in [1], [3], [17], [23]multicast a data packet by transmitting it just once. An underlying assumption behind this just-once transmission is that all the desired receivers are available at the same time.…”

“…Some MAC protocols use a control channel to exchange transmission related information [1], [10], [24], whereas some protocols do not use a control channel [2], [4], [23]. Some advantages of not using a control channel are that the underlying hardware may require one less pair of dedicated transceivers, and one more channel is available for data transmission [4].…”
