.... multiplexing (WDM) To alleviate the electro optic bottleneck and provide transparency, several photonic switching techniques have been proposed such as photonic slot routing (PSR) optical packet switching (OPS) optical label switching (OLS) and (labeled) optical burst switching ( L)OBS) 4] [6]. Those approaches reduce the requirements on electronic processing devices by keeping the payload in the optical domain. Note that no optical random access memory (RAM) is feasible at present. Instead, simple ber delay lines (FDL) with a xed delay are used. While those delay lines allow for ....

....electronic control network, such as an IP or ATM network. In either case, the separation of control and data, both in time and physical space, is one of the main advantages of OBS. It facilitates ecient electronic control while it allows for a great exibility in the user data format and rate [8] because the bursts are transmitted entirely over an optical signal and remain transparent throughout the network. In general, all OBS designs include an o set time between the transmission of a control packet and its corresponding burst. This o set al..lows the control packet to reserve the needed ....
....routing algorithm. First and foremost, the high OBS transmission rates demand a very fast route calculation. Therefore, the conventional hop by hop IP routing is not suitable for OBSNs but rather IETF s multi protocol label switching (MPLS) will be more advantageous. In fact, some OBS papers [16, 17, 8] discuss the implementation of MPLS in an OBS network. The idea is to assign the control packets to forward equivalent classes (FECs) at the OBS edge nodes in order to reduce the intermediate routing time to the time it takes to swap the labels. The second requirement for OBS routing is the ....

.... [5] 12] and [17] give rise to the need for performance evaluation methodologies that will support business decisions on technology migration, network dimensioning and Service Level Agreements (SLAs) A preferred option for optical packet switching systems is Optical Burst Switching (OBS) see [10], 12] 15] 17] and [18] that has been proposed as an efficient switching technique to exploit the terabit bandwidth of Wavelength Division Multiplexing (WDM) transmission technology. In OBS, IP packets with a common destination arriving at the same ingress node are aggregated into large ....
....and reserves the relevant link bandwidth (if available) for the entire burst as soon as it arrives at the switch. The variation we consider is without acknowledgement as the maximal burst size is typically small compared with the link transmission capacity. The Just Enough Time (JET) protocol [10], whereby the control packet is aware of the burst length and reserves the link bandwidth (if available) for the burst duration starting from the predetermined time offset. The Burst Segmentation [3] and [15] whereby the reservation (control) packet is aware of the burst length and reserves ....

....packet switching. As such, a burst may be considered as having an intermediate granularity as compared to circuit and packet switching. OBS uses one way reservation schemes with immediate transmission, in which the data burst follows a corresponding packet without waiting for an acknowledgement [6, 7, 8, 9, 10, 11]. 1.1 OBS Network Architecture In optical burst switched networks, bursts of data consisting of multiple packets are switched through the network all optically. A control message (or header) is transmitted ahead of the burst in order to configure the switches along the burst s route. The data ....

....the control packet with burst information for the next node and forwards it on. The ingress forwards the control packet further on downstream toward the egress through every node on the alternate path. Thus, the whole path is setup using the Just Enough Time (JET) burst switching technique. [8, 9, 10] suggest that such a signaling scheme which couples data bursts in a high speed OTN and control packets in a slower DCN is indeed practicable. Since the transmitting node (i.e. the node immediately upstream to the failed link) does not wait for an acknowledgement of path setup before forwarding ....

....inside the ENs. As far as the choice of the optical packet length is concerned, two solutions have been proposed: fixed size or variable size packets. The former is basically adopted in the Optical Packet Switching (OPS) 3,4,5] whereas the latter is utilized in the Optical Burst Switching (OBS) [6,7,8,9]. OPS is based on a synchronous node operation and on a coupled transport of header and payload. On the contrary, OBS allows an asynchronous node operation and uses a wavelength decoupling of the packet payload, named Burst, from its header, called Burst Control Packet (BCP) In this paper we ....
