A fundamental issue in all-optical switching is to offer efficient and cost-effective transport services for a wide range of bandwidth granularities. This paper presents multi-granular optical cross-connect (MG-OXC) architectures that combine slow (ms regime) and fast (ns regime) switch elements, in order to support optical circuit switching (OCS), optical(More)
This paper presents the TSON metro mesh network architecture for guaranteed, statistically-multiplexed services. It proposes tunable time-wavelength assignment, one-way tree-based reservation and node architecture. Results demonstrate high network efficiency, fast service delivery and guaranteed QoS.
An enhanced version of hardware accelerated QoT estimation tool in impairment-aware optical network is demonstrated and evaluated against the different number of lightpaths and wavelengths per link. It outperforms the software version by 28 times in the order of millisecond.
The paper presents the architecture, implementation and evaluation of the flexible and finely granular Time Shared Optical Network metro node (TSON). The results show exceptional performance, throughput 95.38% of theoretical maximum, latency less than 160μsec and jitter less than 25μsec.
The paper presents a novel network architecture on demand approach using on-chip and-off chip implementations, enabling programmable, highly efficient and transparent networking, well suited for intra-datacenter communications. The implemented FPGA-based adaptable line-card with on-chip design along with an architecture on demand (AoD) based off-chip(More)
This article presents a novel application-aware network architecture for evolving and emerging IT services and applications. It proposes to enrich an optical burst switching network with a session control layer that can close the gap between application requests and network control. The session control layer is implemented using the session initiation(More)
This paper presents some instantiations of novel application-aware network architectures for emerging IT services and future Internet applications. It proposes and analyses network architectures where the Control and Service Planes are closely and seamlessly interacting with the applications. In one instantiation, the Grid-GMPLS (GMPLS, as defined by the(More)
