“[…] WP4 aims at desigining the virtualization approach for the provisioning of inter-domain and inter-technology end-to-end services […]”

(DoW, WT3, pp. 22)


[O1] Define the CONTENT virtualization approach for integrated wireless access, optical metro and IT virtual infrastructures

– Per-domain virtualization models based on resource or service virtualization, or hybrid approaches

[O2] Design interactions and interfaces with wireless, optical and IT infrastructure control/management planes

– Architecture and procedures for cross-domain control and management of multi-technology virtual infrastructures

[O3] Implement a proof-of-concept prototype of the virtualization tools

Virtual Infrastructure Planning

– Technology-specific virtualization on each phy domain

– VI planning taking a holistic approach It considers jointly the heterogeneous network technology domains and the IT

resources comprising the PHY infrastructure, to offer a globally optimal solution

Through this joint consideration, it is ensured that sufficient resources are allocated accross all infrastructure segments

– To support the volume of service requests

– To support their specific characteristics (required QoS, or mobility for end-users)

Task 4.1: the results (2) CONTENT cross-domain virtualization

• Initial numerical results available in D4.1• Extensions made from architectural perspective

later in D2.3• Further simulations planned in T2.3 for the next

year


Analysis and evaluation of possible approaches to operate a multi-technology virtual infrastructure– Definition of CONTENT control and management functions

At the single domain level On the whole infrastructure

– Evaluation of existing solutions for TSON domains Distributed GMPLS and PCE architecture from MAINS project Centralized solution based on Software Defined Networking

paradigms

– Evaluation of existing solutions for wireless domains OMF for control and management framework for wireless test-beds

– Initial identification of extensions in support of CONTENT-oriented features Flexible resource configuration, cross-layer interfaces towards cloud

orchestrator, multi-technology procedures
