This equipment will provide AAI with dedicated circuit bandwidth and will multiplex all of the communications circuit at a site onto bulk bandwidth communications transport circuits with required levels of serviceability. FTI Infrastructure of AAI CPE & Managem ent Dash Board NOCC SOCC Media OFC/VS AT/Micr owave How Transition will take Place? • In phased manner • Service provider is supposed to follow the project time line as provided by AAI • Build Own Operate (BOO) model to save cost in Capital Expenditure • Present resources may be utilized by service provider AAI’s Future Plan • Air Traffic Flow Management ( ATFM) • VCCS growth/upgrades (VCCS) • Automated Dependent Surveillance Broadcast (ADS-B) • GAGAN • New RCAG site plan • New long range RADAR plan • New Greenfield's airports • Re sectorization and ACC consolidation • Mixed use airspace coordination with the IAF POST FTI SCENARIO • Achieve a common infrastructure, to meet operational and mission critical voice, data and video requirements. • Obtain the required telecommunications services at the ordered performance levels. • Pay commercial prices that can be optimized over time by the use of price management mechanisms for future services. continued POST FTI SCENARIO • Receive centralized, detailed, timely network management information that can be viewed anytime by AAI management as well. • Provide a single source for network status and service ordering, billing and invoicing Implement new technologies that can be quickly introduced. • Maximize the use of existing commercial systems in the areas of network management and business processes. GLOBAL SCENARIO • FAA & EUROCONTROL have taken lead for the establishment of managed communication infrastructure . • FAA managed telecommunication infrastructure is a single scalable nationwide communication network implemented in 12 year span supporting more than 22,000 services at 4000 locations. • The pan –European network service(PENS) is an international communication infrastructure jointly implemented by Eurocontrol & 38 European air navigation service providers(ANSP) in order to meet existing & future air traffic communication requirements. Scope of Work • Exclusion of low volume circuits like VAH (Value added Hotlines), Dial up Circuits & local hot lines from scope of work • RC lines/Media within Airport operational area shall be considered after stabilization of the FTI network. • RC lines/Media outside Airport operational area are included in scope of work. Scope of work Continued.. • It should be service provider’s responsibility to provide HVAC (Heating, Ventilation and Air-conditioning) equipments in the room provided to MSP for housing of Network equipments. • Service provider should provide cabling up to AAI’s equipments rather than up to common service delivery points (SDP). • Service provider should provide its own dedicated earthing to connect CPE. Scope of Work Continued.. • Provide space free of charge for installing Customer Premises equipments (CPE) • Provide chargeable space if required for logistics support such as deployment of manpower, stores depot etc as per AAI’s Commercial policy • Provide metered raw AC essential power supply to energize service provider’s equipments. Recommended SLA’s Serviceability Un/Availability serviceability time allowed per month 99.999% 27 Sec Services /Applications 99.99% <4 min 99.9% <44min Radar Data, RCAG, ATFM , ADS-B AMSS & DSC Gagan FTI network Implementation Estimated Timelines • The FTI network implementation timeline begins at contract signing. A timeline of activities in order includes: • Procurement and outfitting of facilities • Procurement and build of NOCC/SOCC systems • Beginning Engineering of site and telecommunications • NOCC/SOCC facility completed and staffed • Beginning site and service installations • Site and service cutover from AAI to FTI network Cost recovery/Revenue model While this new system will provide required SLA & necessary provisions for our future needs of operational growth & global harmonization issues, it will also ensure reasonable source of revenue to offset the expenditure incurred in this project by allowing other aviation entities to share data & connectivity without compromising security of our network. Cost recovery/Revenue model Contd. Besides the above, since all the surveillance data pertaining to radar, ADS-B etc from different area control/locations can be made available in the FTI cloud along with VHF communication Air/Ground data, with appropriate agreement and suitable contract formality we will be in a position to work with the neighboring ANSPs and develop more efficient RNP routes in our Sub-Region. (e.g. ADS-B data of Coco island (Myanmar) and Port blair). This arrangement will enhance safety, less fuel consumption thereby reducing carbon emission and more RNFC to AAI Proposed System Design Initial model will be a mix of MPLS cloud & existing point to point links (MLLN) however the MSP will be authorized to have freedom to rework & go for fresh contract for existing MLLN circuits to meet the AAI’s SLA requirement. Layer 3 VPN VS Layer 2 VPN • • • • • • Customer packets are routed across The Customer Frames are switched over the Service provider Edge routers Service provider backbone Service provider backbone Layer 2 Service Provided by Service provider which offers better flexibility provider for management Fully resilient services with auto No resiliency can be offered as in layer 2 switchover can be offered like circuit service provider do not have the dual last mile , dual flexibility router , and dual POP. Managed and Unmanaged CPE options No proactive monitoring can be offered as with proactive monitoring so that if a we just providing a layer two service , link goes down can be detected anytime a circuit goes down customer automatically needs to reactively log a compliant Hub and Spoke and Full Mesh Point to point and Hub and spoke connectivity options available connectivity options are available. Service Provider provides the IP Service provider does not provide IP address address Proposed System Design contd. The MSP will provide Dedicated Network Operations Control Centre (NOCC) & Security Operations Control centre (SOCC) enabling dynamic management of Bandwidth having redundant multilayer media connectivity. By the provisioning of NOCC/SOCC, effective SLA monitoring & security of data can be ascertained. Proposed System Design Contd. The system will be technology and protocol transparent, providing integration and interpretation of data pertaining to divergent systems. The contract period under this model would be for 15 years, however the same can be extended on mutually agreed conditions. The requirement of technology refresh will be assessed & reviewed at every 5 years. Proposed System Design Contd. The above assessment entails a suitable arrangement of providing end user equipments like router, multiplexers and switches etc. of appropriate capacity & redundancy to cover our future bandwidth needs. Transition to new system • Build Own Operate (BOO) model • Transition in phased manner • Service provider is supposed to follow the project time line as provided by AAI • Present telecom infrastructure is to remain in operational readiness and to be utilized by service provider in the event of any failure of the new FTI system for sustaining uninterrupted operations. • Further, MSP may also include some part of the existing Telecom infrastructure in their network for locations not covered by POP(Point of Presence) of their Telecom media provider. • Remaining telecom media will be surrendered once the reliability and the stability of new FTI system is ascertained. Tendering Model • Average budgetary cost of the project will be about 52 Crores per annum .Expenditure on this account/project will be under OPEX instead of traditional CAPEX. • Global tender route • Quality and Cost-Based Selection(QCBS) to ensure only competent eligible with proven track record bid Secured Internet Gateway • The SOCC shall have the capability to manage encryption for AAI authorized Users accessing network resources from outside of the network, or using the public internet to access network resource through a secure network gateway Intrusion Prevention System • Intrusion prevention systems (IPS), also known as intrusion detection and prevention systems (IDPS), are network security appliances that monitor network and/or system activities for malicious activity. The main functions of intrusion prevention systems are to identify malicious activity, log information about this activity, attempt to block/stop it, and report it. continued • Intrusion prevention systems are considered extensions of intrusion detection system because they both monitor network traffic and/or system activities for malicious activity. The main differences are, unlike intrusion detection systems, intrusion prevention systems are placed in-line and are able to actively prevent/block intrusions that are detected. Common regional VPN for Asia Pacific Region • In line with the PENS (Pan European Network), a decision was taken in APANPIRG/24 to establish a taskforce consisting of subject matter expert to study Common Regional Virtual Private Network (CRVPN) for Asia Pacific Region. India is also participating actively in this study as one of the members because it is on similar lines of FTI. Continued • This task force will report the outcome of this study to APANPIRG/25 through Aeronautical Communication Services Implementation Co-ordination Group (ACSICG) and CNS Sub Group of APANPIRG. If decided favourably, all the point to point communication links working within different countries in Asia Pacific region shall be connected with each other in cloud environment. This would also pave a way for implementation of SWIM under the block B1 of ASBU.
