In this paper, we deal with the problem of scheduling packets in an input queued switch when both unicast and multicast traffic are present over broadcasting networks such as Ethernet-Passive Optical Network (E-PON). We propose a Multicast Bypass (MULBY) architecture to perform integration efficiently and to support QoS class traffic. The architecture helps existing unicast scheduling algorithms to support integrated traffic. The MULBY is devised for easy implementation eliminating the need of traditional integrated scheduling problems such as complex fanout splitting and unicast integration problem [1]. Numerical analysis and simulation study is performed to show that the proposed MULBY architecture improves average latency of unicast traffic significantly even in the high ratio of multicast traffic when round-robin matching (RRM) or iSLIP is used as a scheduling algorithm.
