CONTENT WP2 Year 1 Review, Brussels.BE 18 MOVNO Business Model (I) The VO is then able to provide SP the ability to provide services to its customers. The PIP provides the VO with logical resources and composes virtual infrastructures on top of its physical resources.

CONTENT WP2 Year 1 Review, Brussels.BE 19  The PIP will establish pay-as-you-go contract and an SLA agreement with the VO in order for the VO to spread its reach, whilst the VO will provide the SP the ability to increase its business opportunities through contracts that will be established with new customers. – The MOVNO will pay the PIP per usage e.g. per access, per user and avoid the flat rate per period. – The SP will pay the MOVNO depending on the network usage. MOVNO Business Model (II)

CONTENT WP2 Year 1 Review, Brussels.BE 20  2 use cases were selected as potential candidates to demonstrate and evaluate the CONENT during the trials and evaluation period: – Mobile Optical Virtual Network Operator (MOVNO) in a multi-operator environment – Mobile broadband-enabled cloud services by MOVNO  The selection took into consideration: – The technical innovation – The possibility to deploy the components required by the use case on a test bed for demonstrations – The capability to provide wide support for a variety of services, in order to allow the validation of the CONTENT solution in different contexts and conditions – The requirements described in D2.1 Early Platform Evaluation Plan

CONTENT WP2 Year 1 Review, Brussels.BE 21 CONTENT Architecture (II) Layered architecture : cross-technology virtualization to support optimised, seamless and coordinated cloud and mobile cloud service provisioning across heterogeneous network domains

CONTENT WP2 Year 1 Review, Brussels.BE 22  The Time Shared Optical Network (TSON) data plane consists of FPGA nodes for high speed processing at 10Gb/s per wavelength data rate  The operational architecture of the TSON nodes involves three layers: – Routing and resource allocation – TSON Layer 2 functions – TSON Layer 1 functions Physical Infrastructure Layer - TSON TSON network interconnecting DC and wireless access networks

CONTENT WP2 Year 1 Review, Brussels.BE 23 Physical Infrastructure Layer - Wireless Network Architecture NITOS testbed architecture  Basic components of the NITOS Platform – NITOS Bridge: point where VLAN network connections through the GEANT network terminate – Openflow based wireless Backhaul network – WiFi/LTE Access network – Control network – Details of the NITOS testbed are provided in D4.1

CONTENT WP2 Year 1 Review, Brussels.BE 24 Heterogeneous Physical Infrastructure Layer: including a hybrid wireless access network (LTE/WiFi) domain, and an optical metro network domain (TSON) interconnecting geographically distributed data centres Interfaces performing: Scheduling Aggregation/De-Aggregation Traffic adaptation QoS Mapping Heterogeneous Physical Infrastructure

CONTENT WP2 Year 1 Review, Brussels.BE 25 Infrastructure Management Infrastructure Management Layer: is overall responsible for the management of the network infrastructure and the creation of virtual network infrastructures over the underlying physical resources.

CONTENT WP2 Year 1 Review, Brussels.BE 26 Converged Service Orchestration Control Layer: responsible to provision IT and (mobile) connectivity services in the cloud and network domains respectively. Service Orchestration Layer: responsible for efficient coordination of the cloud and network resources to enable end-to-end composition and delivery of integrated cloud, mobile cloud and network services in mobile environments with guaranteed QoE.

CONTENT WP2 Year 1 Review, Brussels.BE CONTENT architecture evaluation  Objective: a dynamically reconfigurable, energy efficient virtual infrastructure  VI planning: designing the virtual infrastructures and mapping the virtual to physical resources  Considering: – Energy consumption of wireless, optical and DC domains through relevant models – Mobility of end users  A stochastic mobility model has been adopted to predict mobile users’ locations and ensure seamless service provisioning across the various network segments  The problem has been described through suitable mathematical formulation

CONTENT WP2 Year 1 Review, Brussels.BE Comparison between Mobile Cloud Solutions  Cloudlet Approach: Small DCs in the wireless access and large DCs in the core to support mobile and fixed cloud traffic  CONTENT Approach: DCs fully converged with the broadband wireless access and the metro optical network

CONTENT WP2 Year 1 Review, Brussels.BE Performance Comparison: Delay Comparison in terms of delay between the CONTENT architecture and the cloudlet: Considering that the minimum packet delay in LTE networks is measured to be of the order of 100ms the additional 2ms delay of the CONTENT solution is negligible The additional delay, can be compensated by allocating extra resources in the DC domain

CONTENT WP2 Year 1 Review, Brussels.BE Performance Comparison: Power Impact of traffic load on power consumption for the CONTENT and the Cloudlet scheme the wireless access technology is responsible for 43% of the overall power consumption the optical network consumes less than 7% of the energy

CONTENT WP2 Year 1 Review, Brussels.BE Impact of Mobility  Service-to-Mobility Factor: fraction of the service holding time over the cell residence time  Power consumption increases with mobility.

CONTENT WP2 Year 1 Review, Brussels.BE Integration of Technology Domains 1. TSON nodes receive the Ethernet frames and arrange them to different buffers that are part of the node. 2. The Ethernet frames are aggregated into TSON frames, which are then assigned to a suitable time-slot and wavelength for further transmission in the network on a First In First Out (FIFO) basis. 3. When these frames reach the interface between the optical and the DC domains the reverse function takes place

CONTENT WP2 Year 1 Review, Brussels.BE 38  The overall network power consumption model considers:  The active elements of the WDM metro network, based on the Time Shared Optical Network (TSON), supporting frame-based sub-wavelength switching granularity  A cellular LTE system for the wireless access domain and a collection of wireless microwave links for the interconnection of the LTE-enabled based stations  Linear power consumption for the DCs  100% power overhead due to cooling Network Power Consumption

CONTENT WP2 Year 1 Review, Brussels.BE Numerical Results & Comparisons  The wireless access technology consumes 50%, while the optical network less than 10% of the total energy  There is a trade-off between mobility and utilization of physical resources: For high mobility additional resources are required to support the VI in the wireless access domain This additional resource requirement also propagates in the optical metro network and the IT domain
