Stimulated by the remarkable packet traffic growth, the transport of 100 Gb/s Ethernet (100-GbE) services is to become a reality in a near future. To provide a smooth and cost- efficient network evolution, inverse-multiplexing techniques can be employed to carry the high-capacity data streams. In this context, the virtual concatenation (VCAT) protocol, available in optical transport network (OTN)...
Optical burst switching (OBS) was proposed as an alternative optical switching paradigm, in order to overcome the limitations of optical circuit and optical packet switching paradigms. In OBS networks, resource reservation protocol plays a key role for better resource allocation along the path from source to destination data transmission. In this paper, we focus and consider some of the relevant one-way...
Traffic engineering based on cross-layer communications to counter-act inter-channel impairments in optical networks is shown to yield significant throughput gains for a variety of traffic models.
The problem of designing high capacity and high bit rate IP-over-WDM networks, which can provide uninterrupted service in the presence of network equipment failures, continues to attract significant interest from the research community. An IP-over-WDM network implements Internet Protocol (IP) directly over physical WDM network by establishing lightpaths using IP routers, optical crossconnects (OXC)...
This paper addresses the problem of burst assembly in OBS-GRID networks and particularly the TCP throughput maximization problem for large file sizes. For that purpose, a novel adaptive size-based approach is proposed, following some probabilistic methods and considering the effect of the burstification process in the overall transport system. The scheme has been evaluated in a high capacity GRID...
