“…11, it is clear that simple node abstraction (W = 16) generates nearly two times as many error messages, implying much higher control plane bandwidth and CPU processing overheads. This is a key concern as control plane bandwidth is generally more limited and well below gigabit wavelength capacity, see [1].…”

“…To date, DWDM has emerged as the premiere transport technology and has gained much traction in long-haul and metro/regional domains [1]. DWDM exploits the huge unused spectrum in single mode fiber (SMF) to transmit multiple channels at unprecedented terabits/s speeds.…”

“…This can be achieved via hierarchical routing and topology abstraction techniques which have been well-studied for packet-switching IP and/or cell-switching asynchronous transfer mode (ATM) networks [5,6]. For example the ATM Forum's private network to network interface (PNNI) protocol [1] clusters nodes into peer groups and uses topology abstraction to hide internal state from outside users [5]. Although these principles have recently been extended for DWDM networks [7,17], these studies have not considered the impact of large scale wavelength conversion.…”

“…Access data rates have increased from kbit/s to Mbit/s, and new emerging technologies promise even higher data rates up to Gbit/s per user. Metropolitan area networks (MANs) will need significant improvement in both capacity and functionality in order to cope with the foreseen bandwidth demand [4]. The technology leaps in the backbone and access parts of the network have so far not been matched with progress in the metro part.…”

“…This will change, however, with the advent of 10 GbE, which allows point-to-point connections of up to 40 km, extending the reach of Ethernet to metropolitan-area distances. Such an implementation of Ethernet in the core may yield cost benefits through a less complex network design with fewer layers and provide a simpler, more scalable, homogenous campus-to-campus and metropolitan-area network (MAN) [2]. Inevitably, there are problems with the current versions of Ethernet as a protocol for the MAN.…”

Abstract-This paper investigates the challenges for developing the current local area network (LAN)-based Ethernet protocol into a technology for future network architectures that is capable of satisfying dynamic traffic demands with hard service guarantees using high-bit-rate channels (80. . .100 Gb/s). The objective is to combine high-speed optical transmission and physical interfaces (PHY) with a medium access control (MAC) protocol, designed to meet the service guarantees in future metropolitan-area networks (MANs). Ethernet is an ideal candidate for the extension into the MAN as it allows seamless compatibility with the majority of existing LANs. The proposed extension of the MAC protocol focuses on backward compatibility as well as on the exploitation of the wavelength domain for routing of variable traffic demands. The high bit rates envisaged will easily exhaust the capacity of a single optical fiber in the band and will require network algorithms optimizing the reuse of wavelength resources. To investigate this, four different static and dynamic optical architectures were studied that potentially offer advantages over current link-based designs. Both analytical and numerical modeling techniques were applied to quantify and compare the network performance for all architectures in terms of achievable throughput, delay, and the number of required wavelengths and to investigate the impact of nonuniform traffic demands. The results show that significant resource savings can be achieved by using end-to-end dynamic lightpath allocation, but at the expense of high delay.
