Integrating Circuit Emulation Service and Modified Packet Bursting technologies in metropolitan optical network

With the growth in data traffic, modern MAN networks are moving away from traditional circuit-switched networking technologies towards high-speed packet-switched networking technologies, which support best data traffic, offering high flexibility, cost-effective and easy-installation solution. Circuit emulation service (CES) is introduced in packet-switched networks in order for them to support traditional TDM (circuit-switched) traffic. Modified packet bursting (MPB) is introduced in packetswitched network to improve protocol transmission efficiency and, accordingly, network performance. This paper presents the performance analysis of those two technologies on an all-optical Ethernet ring, demonstrating CES performance improvement thanks to MPB.
