Blocking and delay analysis of single-wavelength optical buffer with delay constrained packets

Hongxu Lu, Shengda Tang, Liansheng Tan, Wei Zhang

Photonic Network Communications > 2018 > 35 > 1 > 11-19

Within the communication networks, a delayed constrained data packet is the one that will be dropped if not being served before a certain deadline time, which causes data packet loss affecting the quality of service (QoS). In this paper, we study the blocking probability and the mean delay of such delay constrained packets in an asynchronous single-wavelength optical buffer in optical packet switching...

Performance Modelling and Traffic Characterisation of Optical Networks

Harry Mouchos, Athanasios Tsokanos, Demetres D. Kouvatsos

Lecture Notes in Computer Science > Network Performance Engineering > Optical Networks > 859-890

A review is carried out on the traffic characteristics of an optical carrier’s OC-192 link, based on the IP packet size distribution, traffic burstiness and self-similarity. The generalised exponential (GE) distribution is employed to model the interarrival times of bursty traffic flows of IP packets whilst self-similar traffic is generated for each wavelength of each source node in the optical network...

Journal of Lightwave Technology > 2013 > 31 > 18 > 3032 - 3042

Optical WDM metro-ring networks have been considered to be promising solutions for wireless backhaul. In this paper, we propose an integrated traffic control scheme (ITCS), which facilitates circuit emulation service (CES) for wireless backhaul over a previously proposed experimental optical packet-switched WDM metro-ring network, HOPSMAN. The ITCS seamlessly integrates variable-bit-rate (VBR) CES...

Bounds of the overflow priority classification for blocking probability approximation in OBS networks

Shuo Li, Meiqian Wang, Eric W. M. Wong, Vyacheslav Abramov, more

IEEE/OSA Journal of Optical Communications and Networking > 2013 > 5 > 4 > 378 - 393

It has been demonstrated that the overflow priority classification approximation (OPCA) is an accurate method for blocking probability evaluation for various networks and systems, including optical burst switched networks with deflection routing. OPCA is a hierarchical algorithm that requires fixed-point iterations in each layer of its hierarchy. This may imply a long running time. We prove here that...

Recirculation buffer modules combining arrayed waveguide gratings (AWGs), tunable wavelength converters (TWCs), and fiber delay lines (FDLs) have been proposed to bypass the existing switching bottlenecks in massive-scale data centers. Performance studies of such subsystems are devoted exclusively to either the network layer or the physical layer aspects. Network layer studies consider packet drops...

2011 IEEE 12th International Conference on High Performance Switching and Routing (HPSR)

All-optical switching has been proposed to overcome the limitations of electronic switches in terms of scalability, speed, footprint, and power consumption. A key passive optical component to bypass electronic processing limitations is the arrayed waveguide grating (AWG). Switch architectures combining wavelength converters and fiber delay lines provide tunable routing and contention resolution when...

Hybrid buffering architecture for packet contention resolution of an optical packet switch

Ahmed Galib Reza, Hyotaek Lim

Optik - International Journal for Light and Electron Optics > 2011 > 122 > 7 > 591-593

Packet contention is a major issue in optical packet switching network and it is not a trivial task to resolve due to lack of optical RAM technology. In order to resolve contention optical buffering approach is used using fiber delay lines (FDLs). Yet there is a heavy packet loss rate due to unavailability of output port and free FDLs. This paper proposes a hybrid buffering architecture using feed-forward...

Journal of Lightwave Technology > 2011 > 29 > 4 > 396 - 402

Optical buffering has been one of the major technical challenges in realizing optical packet switching (OPS) routers. While fiber-delay-line-based (FDL) buffers are the most practical and realistic solution to offer useful amount of capacity, the bulkiness of long FDLs and optical switches has been the main obstacle to practical implementation. This paper demonstrates a compact optical buffer with...

The International Conference on Information Networking 2011 (ICOIN2011) > 414 - 418

2011 International Conference on Information Networking (ICOIN)

In optical packet switching (OPS) network, packet contention is a critical factor which occurs at a switching node whenever two or more packets try to leave the switch fabric on the same output port, on the same wavelength, at the same time. Optical buffering approach based on fiber delay lines (FDLs) is the most cost-effective as well as the widely used solution for contention resolution. This paper...
