7 Integration is the key objective
Integration goals Strengthen contacts between partners Focus research on optical networking Stimulate exchanges of researchers and lecturers Support knowledge management and circulation of information Sharing of research topics and activities Sharing of lab infrastructures Develop common educational programs Support innovation management The NoE is managed on the model of a university, with Virtual Departments [VDs] and specific Joint Projects [JPs]

8 Virtual Departments Integration activities are organized in thematic structures called Virtual Departments (VDs) Viewing e-Photon/ONe+ as a large virtual European research structure (e.g. a university), it is possible to envisage different departments to which people affiliate according to topics. Departments have chairpersons who decide on the activities and the internal organization. Examples of activities: coordination of similar existing research editing of joint technical reports and papers organization of workshops encouraging mobility actions coordination of teaching activities coordination of proposals for new projects

9 e-Photon/ONe+ Virtual Departments and Chairs
VD-C (UniBO) VD-M (Telenor) VD-A (Tu/e - UPC) Core Networks: Technologies, Architectures, and Protocols Metro Networks: Technologies, Architectures, and Protocols Access Networks: Technologies, Architectures, and Protocols VD-H (UDE - PoliTO) VD-S (DTU - CTI) VD-T (PoliTO) Home Networks and Other Short-Reach Networks Optical Switching Systems Transmission Techniques for Broadband Networks

10 Joint Projects Five joint research projects (JPs) have been defined. JPs are specific, short-term research activities, that may involve people from a single or multiple departments, just like the many research projects in which university staff people are often involved. Research activities in each JP are decided by e- Photon/ONe+ government bodies, and coordinated by the WP leader. JPs are serving as an important step toward integration inside the NoE, providing to a large number of partners an opportunity for interaction and accomplishment of common goals.

23 Joint research Activities

24 Role of the JAs Use acquired expertise to support new activities:
One partner state the problem, another support the solution Compare different approaches Provide insight into problems by comparing already existing approaches Integrate expertise in different technical areas Create a team of experts in different topics and tackle a problem that none of them would be able to address alone Effects: Start with a number of bi-lateral collaborations Enlarge the bi-lateral collaborations into clusters of collaborating partners Create fully integrated multi-institution and distributed research teams

25 Activity 1 - The OBS Book Motivation Goal Results
A large amount of work exists on congestion resolution in OPS Very little “engineering” suggestions Goal Look at congestion resolution in OPS under a new perspective Results Congestion resolution in the wavelength or time domain alone is always worst than a combined approach Just one delay provides a great performance improvement Define a formal term of “fair” comparison between alternative approaches Trivial: performance get worse as soon as the conversion capability is reduced Interesting result: with smart wavelength conversion techniques (VB), limited range conversion may perform better than full conversion

26 Activity 2 Motivation Goal Background Joint activity:
Maintain packet order in OPS networks with a fixed packet size Goal Evaluate the performance benefits vs. cost of using synchronization stages to align packets at the switch inputs Background Ordering when synch stages are used studied at UPCT OPS switching systems studied at UPC Joint activity: Propose a round-robin criteria for ordering in asynchronous networks Propose a scheduler for output buffered architectures (like KEOPS) with no synch stages that preserves packet sequence following the new criteria Compare the performance of synch /asynch approaches, and try to answer the question: when and how the synch stages pay?

27 Activity 4 Motivation Goals Results
Qualified applications may benefit from the QoS-enabled services provided by GMPLS-based transport networks The GMPLS/OIF User to Network Interface (UNI) is not conceived for being directly invoked by applications Goals Service Platform (SPF) to provision on-demand GMPLS services (e.g., LSP-MPLS, VPN L2, VPN L3 ) to applications Service Abstraction and Resource Virtualization Results The support of the BGP/MPLS VPN provisioning to application by the SPF prototype experimentally demonstrated Multi-Vendor routers interoperability tests for the provisioning of BGP/MPLS VPN services executed Deploying the SPF prototype within the ACREO testbed

28 Activity 5 Motivation Background Aim:
Shared Path Protection (SPP) promises more efficient use of the network resources and lower recovery time Background CTTC is implementing SPP over the ADRENALINE all-optical network testbed POLIMI has gained a wide experience on simulative comparison of different SPP approaches Aim: investigate effects of outdated control information on SPP investigate requirements and algorithms to apply SPP without wavelength conversion

29 Blocking Probability Pb
3 phases: 1°: outdated information does not influence performance (negligible delay) 2°: logaritmic increase of Pb for increasing delay 3°: Pb reaches a saturation value and is no more influenced by the delay 1 A r 1 A r 1 A r 1 8 1 % k c 1 o l B P , 1 , 1 , 1 1 - -5 , 1 , 1 1 , 1 1 1 1 delay r i t a r d o ( s )

30 Activity 6 Motivation Goals Background Summary of results
Inter-domain connections are are high-value and should be as reliable as possible Goals Propose a p-cycle-based solution to protect inter-domain connections Background Match UC3M expertise in multi-domain networking with BME experience in p-cycle application to routing problems Summary of results new inter-domain cycle planning method and intra-domain cycle- resolution are proposed to achieve further reliability simulations prove the provided higher reliability and estimate the resource consumption on different topologies protocol issues of inter-domain protection are discussed and a PCE- based solution is proposed, in accordance with IETF recommendations

31 Activity 7 Motivation Summary of results
MLMC investigates optimal multicast delivery over a two-layer optical network featuring traffic grooming Summary of results An analysis and modeling of the target network scenario has been carried out by BME BME has studied the problem of regular reconfiguration to deal with the degradation of the optical tree due to the dynamic nature of membership/demands. UC3M is addressing the control plane issues to enable seamless reconstruction and fitting the model to a real- world setting (IP multicast and L2VPN broadcast trees).

32 Blocking Ratios vs Traffic Unpredictibality
Activity 8 UGent’s Multi-Layer TE Strategy: Lightpath Topology and IP/MPLS routes are calculated according to traffic expectation and updated periodically. Bilkent’s Single-Layer TE Strategy: Static lightpath topology designed making use of traffic expectation. Dynamic IP/MPLS routes, LSPs are rerouted. Blocking Ratios vs Traffic Unpredictibality A case study is constructed and two strategies are compared on a common platform + MTE has significantly better bandwidth blocking performance - Significant number of lightpath changes, i.e. set up and tear down (7.9 lightpaths per hour on a 10 node network) Number of lightpath changes vs. Hours in MTE strategy for a 10 node network

33 Activity 10 Goals: Background
study the possible approaches to encompass physical impairment parameters within GMPLS Physical impairment modeling Impairment-aware RWA algorithms Background Integrate FT physical-layer modeling into SSSUP signaling- based approach for impairment-aware RWA Use of FT physical layer modeling to enhance CTTC's single link parameter modeling for impairment-aware RWA Compare the SSSUP signaling-based and CTTC routing-based approaches taking into account the same impairment information

34 Preliminary results FT modeling applied to SSSUP’s signaling-based approach
1 2 3 5 4 6 Considered physical impairments (so far): PMD, CD, Noise, Non-linear Phase Shifting OSNR threshold to evaluate the quality of the signal Signaling-based approach: impairment-unaware routing computation and dynamic evaluation of the Signal Quality during the signaling. Successive set up attempt may be required. Preliminary results in realistic scenario show the significant blocking probability reduction already at the second set up attempt

35 Durable Integration VDs are paving the road towards durable integration by Promoting joint research activities (JAs) Identify new key research topics Create common expertise and methodology Joint Research Activities (JAs) are key to “integration” Quality and quantity of research improved Qualified outputs: joint papers and research tools Several outputs would not be achievable without collaboration Common expertise and methodologies are a first step of integration Strengthened mutual knowledge Favour mobility Learn to delegate problems to others Share tools and instruments Re-focusing of research is a longer term effect of integration See further together than the isolated groups can see isolated

60 Research Example: JA2- Hybrid Optical Burst Switching - HOBS- Architecture
Pure Packet Switching big IP routers processing overhead max transmission resource sharing poor scalability, good flexibility Wavelength Switching (ASON) reduced packet handling low transmission resource efficiency good scalability, mediocre flexibility Hybrid Switching combines wavelength and packet switching is based on ASON managed interconnections ASON reacts to long term traffic pattern variations by reconfiguring the wavelength paths enables full sharing of all wavelengths on a link

61 Research Example: JA2- Hybrid Optical Burst Switching - HOBS- Architecture
HOBS Concept … according to a bandwidth request for node sh TRTT corresponds to the two-way propagation delay from the source to the destination of the request Node s0 sends a SETUP message to sh, to reserve resources After a small time-offset s0 transmits a burst of BE data to sh If reservation succeeds Circuit Switched (CS) data arrive at least a round trip time later. This applies to all nodes. When node si receives the SETUP message, it reserves an outgoing wavelength, it forwards the SETUP packet and the following bursts and (possibly) adds is own burst (s)

62 Research Example: JA2- Hybrid Optical Burst Switching - HOBS- Architecture
SETUP Message Format The SETUP message, apart from establishing the optical circuit, carries information regarding bursts that follow Information is organized in triplets {B, T0, D} one per data burst, for encoding each burst’s size, time-offset from the setup message, and destination Here we can see the format of the SETUP message, which is used in HOBS

63 HOBS Switch Architecture
Research Example: JA2- Hybrid Optical Burst Switching - HOBS- Architecture HOBS Switch Architecture Hardware Additions: 1 set of 1x2 and 2x1 switches per fiber for inserting / extracting bursts 1 set of receivers and transmitters (tunable) HOBS Agent: It calculates the idle time for best-effort data transmissions It contains a Buffer for storing BE data and a Traffic Scheduler that controls the switches The Switch architecture of a HOBS core node is depicted (edge node: similar, simpler) ---Capable of handling both bursts and traffic… Most of the work is being performed in the control plane, where HOBS employs a dedicated Agent. We have a dedicated agent, implemented in the control plane, where most of the work is performed

64 Research Example: JA2- Hybrid Optical Burst Switching - HOBS- Architecture
Results policy 2 and 3 are capable of supporting, on average, a bit-rate of up to 177Mbits per source-destination pair for a burst arrival rate of λOBS=740 burst/sec, (burst traffic load p = 1)), while policy 1 only 117Mbps. it is clear that policy 2 and 3 can “salvage” up to 340 bursts out from the 740 arrived ones (load p = 1). (a) Burst loss ratio and (b) average packet delay versus burst arrival rate for the three different policies defined. (a) Efficient bit-rate over a specific source-destination pair and (b) Burst sending rate from a single source to all destinations for the three different policies defined

65 Research Example: All-optical high speed  converter based on XPM in HNLF
Tx 80/160 Gb/s EYE (EO, Q) 3 dB DeMUX (10 Gb/s) λ = 1557 nm λ = 1542, 1547, 1550 nm 10, 14, 18 dBm detuned filters Objective: Characterisation and performance evaluation of the wavelength converter using XPM in a HNLF and detuned filters. Principle of operation: Data pulses induce by XPM an instantaneous frequency shift* over the CW-signal. With filters detuned from the CW-wavelength, those frequency shifts are filtered, where the pattern coincides with the original data pattern (wavelength conversion)

Performance degradation effects: cross-talk by the CW “carrier”  CW should be suppressed as much as possible with detuning the filters for high detuning cross-talk either with the original data signal or with the FWM- product may affect. low power for high detuning values (decreased efficiency) walk-off for large separations between data- and CW-wavelength for high data powers spectral broadening due to SPM. Parameters under research: Data-signal power Filter-detuning CW-power CW-wavelength

For MLSE to be able to support km SSMF uncompensated links, substantial progress in digital processing power as well as complexity reduction algorithm are needed.

116 3. SQRT equalizer UPC – IT Effects:
Chromatic dispersion is a linear effect, but produces harmonic distortions in the electrical domain because of the square-law characteristic of the photodiode, and becomes non-linear. These harmonic distortions limit the capacity and reach of digital and SCM, even with Electronic Equalization. Although the phase is lost, if we could detect optical field amplitude instead of optical power, we would take advantage of a more linear relationship between chromatic dispersion and the received signal, using a linear equalizer at the end of the optical network. The idea is: Use a Square Root module could compensate for the square-law characteristic of the photodiode. a non-linear equalization applied at the physical transport layer overcomes the transmission limitation in the electrical domain, providing an extremely more cost effective solution. SQRT eq. module chip layout developed by UPC. Next - Expand this to operation at 40Gb/s.

117 4. Dispersion compensation in MMFs

143 WP-L Joint Experiments
“Ultrafast characterisation of Semiconductor Optical Amplifiers.” Objectives: Demonstrate the applicability of the L-FROG technique for the characterisation of the dynamic response of fast optical devices. Characterisation measurements of an MZI-SOA when this is operated in either XGM or XPM regime. Partners: UPVLC and ORC

144 Experimental results (1)
Study of the XGM response in an SOA After compression induced by the pump, the gain shows a fast recovery, resulting from intraband effects. After the fast gain recovery, the gain is recovering toward the unsaturated value as a result of electrical pumping. Increasing in ER of 9 dB by increasing the signal power between -7 and -12 dBm, this effect is due to the gain saturation. Rise time is longer than the fall time, the negative chirp (-65 GHz) is larger than the positive (13 GHz). The phase changes that occur simultaneously with the gain compression and recovery time are the result of nonlinear refractive index variations in the amplifier. -13 dBm Slow Gain -12 dBm 0.9 Compression Total Gain Compression -10 dBm -7dBm 0.8 0.7 0.6 Intensity a.u. 0.5 0.4 0.3 0.2 0.1 -100 -80 -60 -40 -20 Time (ps) 20 40 60 80 100 Figure 1.- Measured probe transmission pulses for different pump peak powers.

Study of XPM response in an SOA Polarizing the MZI OOP (Out of Phase)  converted signal will be inverted Input signal (at 1550nm) depletes carrier density - modulates refractive index - thereby results in phase modulation of CW signal (1540 nm) coupled into the converter As in the XGM case, the converted pulse is first negatively chirped due to the changes in the refractive index caused by the leading edge of the pump pulse and then positively chirped due to the recovery time Higher ER is measured relative to XGM case Chirp excursion is lower than in XGM – which fits with theory -100 -80 -60 -40 -20 20 40 60 80 100 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 1 Time (ps) Intensity (a.u.) 0 dBm -5 dBm -10 dBm Figure 3.- Converted pulses measured from 1550 to 1540nm after SOA-MZI with XPM setup for 7ps pulses. -10 -9 -8 -7 -6 -5 -4 -3 -2 -1 2 3 4 5 6 7 8 9 10 CHIRP(GHz) Signal Average Input Power (dBm) -10 -9 -8 -7 -6 -5 -4 -3 -2 -1 -35 -30 -25 -20 -15 CHIRP (GHz) Signal Average Input Power (dBm) So the red shift (-34 GHz) is lower than in XGM If we assume that the MZI is perfectly balanced, and we neglect the chirp produced by the SOA1 in XPM, the chirp excursion in XGM is two times the chirp in XPM Figure 4.- (a)Blue Shift measured in XPM (b) Red Shift measured in XPM
