Optical Burst Switching (OBS) is an optical switching technology capable of supporting large demands for bandwidth in optical backbones with Wavelength Division Multiplexing (WDM). This paper presents an OBS simulation model for the discrete event simulator OMNeT++. The performance of this model is compared with the performance of the well-known INET simulation model for IP networks. Both model...

Inhibition and switching are executive functions (EFs) that have different developmental trajectories across childhood. The development of specific processes unique to each EF may contribute to these trajectories. Interference suppression and reversal were examined in a large sample of children aged 7 and 9 years (n = 120) and followed-up after two-years to investigate developmental trajectorie...

Most of the initial efforts to utilize Generalized MPLS (GMPLS) have been related to environments hosting devices with a single switching capability. The complexity raised by the control of such data planes is similar to that seen in classical IP/MPLS networks. By extending MPLS to support multiple switching technologies, GMPLS provides a comprehensive framework for the control of a multi-layer...

− The optical circuit switching (OCS) is a sophisticated technology widely deployed in current optical networks, and has many advantages to transport the stable and longduration traffic flows. However, it is not suitable for bursty data traffic. On the other hand, an alternate technology, optical burst switching (OBS), well addresses the bursty IP traffic transport, but not suitable for stable ...

Bandwidth allocation in the future multiservice global communication IP network presents a very interesting research issue. This paper presents the strategy of Dynamic Partitioning of link bandwidth in IP network. In the Dynamic Partitioning scheme the bandwidth of each link in the network is partitioned into two fractions, one for the low-priority data traffic, and one for the high-priority st...

The paper addresses the topic of long-haul optical networking for the provision of large-bandwidth IP services. A class of optical packet switching architectures is considered which adopts an arrayed wavelength grating device as packet router. The architecture performs slotted packet switching operations and fully exploits the wavelength routing capabilities by allowing multi-wavelength switchi...

This paper addresses the problem of designing a capacity management/traffic engineering procedure for an IP/MPLS over ASON/GMPLS scenario. We suggest TRIDENT, a procedure whose main goal is to dynamically provide the bandwidth required to transport through an ASON the MPLS–LSPs already established at the IP/MPLS client network. TRIDENT relies on automatically triggering demands to set up or tea...

MPLS (Multi-Protocol Label Switching) and DiffServ (Differentiated Services) provide means to implement various QoS types in IP networks. While MPLS enhances the classical IP networks by supporting efficient connection control through explicit label-switched paths (LSPs), DiffServ allows differentiated QoS parameters commitments to be supported on the same IP backbone for different classes of s...

Mobile IP (MIP) provides a global framework for IP mobility management; however, it is not suitable for micro-mobility environments. Many domain-based micromobility management schemes have been proposed to overcome the limit of MIP. All these scheme delegate to MIP for inter-domain mobility. Recently there is a trend to use Multiple Protocol Label Switching (MPLS) to deal with mobility manageme...
