Architectural vision of network evolution

Deliverable D1.1 deals with basic architectural, technological and network and user services concepts and models to be take as references in all the activities of Nobel phase 2.

The motivation of such reference framework come from the evolution of telecommunication network which is gearing to accomplish more dynamicity on connections and to achieve economic savings so to reduce the cost of ownership of a network and to decrease the industrial cost of a network service. The key leveraging to achieve these results are: packet technologies (in particular IP and a strong development of Ethernet), Control Plane (ASON architecture and GMPLS paradigm) and Optical transparency (to reduce the investments due to transponders). Theses aspects are evaluated separately in the metro and in backbone segments, as the two network segments have different characteristics and requirements and they require specific solutions as a consequence.

The D1.1 is divided in a public part to be freely distributed to the community and a confidential part reserved to the consortium partners.

End-to-end experiments: results and analysis

This deliverable reports and analyses the final results of all the experimental activities related to the large network control plane emulation, the end-to-end experiments and the joint activities with other projects.

Preliminary Report on MTE and Resilience Mechanism - common part

Deliverable D2.1 provides a preliminary description of both resilience and traffic engineering solutions aligned with the architecture vision of network evolution described in D1.1. According to it, we propose technical strategies on traffic engineering and resilience aspects for a NOBEL2 global architecture vision that we called 'umbrella scenario' in this deliverable.

The deliverable is organized with a common part and three parts in which specific aspect are dealth with in deep. The three specific parts, available on separate documents, deal with Service Oriented Resource Management (part 1), Traffic Measurment Characterization and Modelling (part 2) and Resilience (part 3).

The common part resumes the work done in the first 11 months of the project within WP2 and it is organized as follows.

In Section 2, we firstly define the umbrella scenario which describes the main characteristics of the foreseen network architectures for the short, medium and long term where the resilience and traffic engineering mechanisms defined in WP2 would be applied. After that, in Section 3, we include a summary of the preliminary results obtained up to now in TMCM, TE and resilience activities carried out in WP2. In particular, the summary of the results of each activity includes the final objective of each case study and its role in the umbrella scenario as well as a description of the inputs to other WPs and activities (e.g., traffic models and generators, definition of test cases, etc). A proposal for experimental validation of Multilayer TE and resilience concepts is presented in Section 4 Finally, main conclusions of D2.1 are summarized in Section 5.

This is the part 2 of deliverable D2.1 and include the detailed report on Traffic Measurement Characterization and Modelling.

This is the part 3 of deliverable D2.1 and include the detailed report on Resilience.

Report on multilayer traffic engineering mechanisms for NOBEL solutions in medium and long term scenarios

Executive summary for Deliverable D2.2

This deliverable gives an overview of Traffic Engineering (TE) and Traffic Measurement Characterization and Modelling (TMCM) solutions aligned with the architecture vision of network evolution described in the NOBEL 2 deliverable D11 [N2D11]. With a similar structure as deliverable D2.1 [N2D21], we propose technical strategies on traffic engineering for a NOBEL2 global architecture vision that we call 'umbrella scenario¿. The executive summary is organized such that techniques that apply to the same time are presented together, i.e. in this executive summary each scenario has its own section:

· Short term scenario in section 2

· Medium term scenario in section 3

· Long term scenario in section 4

All these sections start with a subsection that is an introduction and a short recapitalisation of each scenario as was described in detail in deliverable D2.1 [N2D21]. Each second subsection is a general executive summary of all the studies performed within this scenario. The final subsection contains more detailed summaries for each performed case study. The order of the studies is the same as the order in the main D2.2 document and with identical titles. Finally, Section 5 presents the status of the work on experimental validation of concepts and techniques developed in WP2, as cooperation with WP1. This section gives an overview on the work on this topic, which is done in several of the studies.

Report on multilayer traffic engineering mechanisms for NOBEL solutions in medium and long term scenarios

This deliverable provides the final descriptions and test results of the experimental work and simulations done in WP1, WP2 and WP5 concerning the service oriented resource management and traffic engineering strategies. For the medium and long term scenarios, guidelines for the optimization of end-to-end services with special focus on the relation between QoS and Service Level Agreement will be given.

Report on resilience mechanisms for NOBEL solutions in medium and long term scenarios

This document proposes technical strategies on resilience for future network development. The case studies are structured according to our vision in which year these evolution steps (scenarios) need to be available for the service provider market. Therefore this document has sections for:

· Short Term Scenarios (Year 2008)

· Medium Term Scenarios (Year 2009 and 2010)

· Long Term Scenarios (Year 2011 and 2012)

Migration guidelines with economic assessment and new business opportunities generated by NOBEL phase 2

D2.4 includes a technical and economic benchmarking of the architectures proposed by WP1 (e.g IP/MPLS over static vs. dynamic optical networks with a distributed control plane) as well as of legacy and new services to be supported by NOBEL solutions (e.g leased lines vs. BoD). This deliverable also provides socio-economic guidelines for helping operators with economic and strategic decisions: network planning, regulatory issues, business models, charging policies, etc. Finally D2.4 identifies and valuates new opportunities generated by NOBEL solutions allowing a more generalized and affordable availability of network services (e.g L1/L2/L3 VPNs) to European users (e.g SMEs, schools, hospitals, etc). Furthermore, this deliverable also evaluates how NOBEL phase 2 solutions may favour a more generalized introduction of broadband services in Europe (e.g favouring the appearance of ISPs reducing their CAPEX and OPEX).

Final report on architectures, evolution scenarios and feasibility studies on opto-electronic burst/packet switching networks and nodes

The deliverable summarizes the work of WP3 on burst/packet network architectures for extended long term scenarios including related CP and MP functions and describes the refined potential evolution scenarios based on the NOBEL network visions. The results of feasibility studies on the selected burst/packet network and node solutions and their related CP and MP functions are reported and further inputs relevant for standardization activities are derived.

Requirements of control and management concepts in multilayer and multi-domain GMPLS networks

The demand for IP network bandwidth is constantly growing as services are moved to IP in Telecommunications networks around the world. To increase the capacity and improve traffic engineering (TE), Generalized Multi-Protocol Label Switching (GMPLS) controlled core networks are introduced. This raises new challenges in multilayer network operation, the result being diverse local and global decision logic, distributed across multiple network elements and multiple network layers. While both GMPLS and Multi- Protocol Label Switching (MPLS) continue their respective expansion, we expect that unified environments will take progressive benefit of GMPLS. Paradigm shifts that result from increasing the efficiency, sustainability, and productivity of transport networks depend on an integrated infrastructure, based on advanced network control and management.

Final report on architectures, evolution scenarios and feasibility studies on innovative management and control issues in ML and multi-domain GMPLS networks

This deliverable reports conclusions on the definition of future proof MP&CP concepts in long term and extended long term NOBEL network scenarios. The result includes specifications of detailed network and management functions and contributions to standardization forums. The deliverable describes collaboration issues and solutions of CP and MP in GMPLS networks as well as interworking issues and solutions of IP and GMPLS networks and comprises a description of a MP&CP migration path to multi-service/layer/domain GMPLS networks.

Description of state of the art and breakdown of work for NOBEL phase 2

During the term of the first phase of NOBEL a lot of progress has been made for the different technologies on the physical layer of optical networks. This progress has been documented in various deliverables of NOBEL in WP5, WP6, and WP7 as well as in other projects and publications. Scope of this deliverable is to summarise the technological progress. From this summary it will be concluded which actions are required. It will be discussed which of these required actions can be covered by NOBEL phase 2 and which actions we recommend to be done from the industry outside the NOBEL consortium

The scientific content of the deliverable is concentrated on the five chapters from chapter 2 to chapter 6, according to the activities:

Chapter 2: Packet-optimised Next Generation metro/regional platforms

Chapter 3: Advanced Burst Nodes

Final report on physical layer network issues

The final deliverable of WP5 summarizes the results achieved during the project. It contains the main achievements of the WP as well as on theoretical studies and identified solutions as on experimental verifications and performance tests. It summarizes the work of all activities in a public report, so that the results will be visible for the audience outside of the project. Especially, the cost model taking into account the physical constraints is extended for hybrid network solutions including network planning routing and wavelength assignment algorithms.
