This airport is the second-largest airport in India and a cornerstone of the country's aviation sector. With over 48 million passengers annually, it faces a unique set of operational complexities that necessitate a robust, highly responsive network architecture.

The Imperative for a Robust Network Architecture

Whether it is real-time flight data, security protocols, or passenger facilitation services, each facet is highly reliant on a robust network backbone. A hiccup in network operations at the airport is not just an internal problem; it reverberates through global air travel, impacting airlines, logistics, and millions of passengers.

Operational Challenges

Network Latency: Intermittent data transmission delays hindered real-time operations like flight scheduling and security protocols.

Scalability: The existing architecture could not efficiently accommodate the airport’s rapid growth and expansion.

Security Gaps: Dated security protocols were insufficient for the modern landscape of cyber threats, posing a national security risk.

Inadequate Data Analytics: Limited real-time data analytics capabilities hampered operational optimization.

System Downtimes: Outages had a cascading effect on operations and associated industries.

Interoperability Issues: The network was a patchwork of disparate systems acquired over the years, lacking seamless interoperability.

The urgency and complexity of these issues required a network overhaul that would be both revolutionary and evolutionary, setting a new standard for what airports around the world should strive for in network architecture.

Objectives for Network Overhaul

The airport has 50+ disparate systems. These systems include Information and Communication Technology (ICT), core Airport Systems like AODB, CUPPS, and FIDS, as well as Building Management Systems (Lighting, HVAC, Fire Alarm) and Security Systems (CCTV and Access Control). Each of these systems not only had to function flawlessly on its own but also interface effectively with one or multiple other systems, depending on business demands.

Such cross-system communication makes an Active Communication Network not just important, but strategically essential. It becomes the backbone that allows an airport to meet its operational and customer service objectives while also providing the high levels of reliability and scalability needed for real-time, mission-critical tasks.

We meticulously outlined the objectives for the network overhaul:

1. Integrate existing systems with advanced solutions.

2. Implement an MPLS network architecture for operational needs.

3. Reinforce security measures across the network.

4. Build scalability and flexibility for future requirements.

5. Enable robust data analytics for operational efficiency.

Along with all these objectives, one more objective was to provide unmatched customer support to travelers, hence the need for an IVRS solution.

Implementing MPLS Network Architecture

For the first time in the history of Indian airports, a carrier-grade, three-tier Multi-protocol Label Switching (MPLS) network was implemented at this airport.

Such rigorous scrutiny allowed us to identify areas for optimization, thereby informing our design choices for a more efficient multi-layered network.

Understanding MPLS Network and Its Suitability

What is an MPLS Network?

Multi-Protocol Label Switching (MPLS) is a protocol-agnostic routing technique designed to speed up and shape traffic flows across enterprise-wide and service-provider networks. MPLS allows for the creation of virtual links between distant nodes regardless of the contents of the data packets being sent, the protocols used, or the intermediary hops traversed.

In essence, MPLS attaches short-label identifiers to packets and routes them based on these labels, which allows for more efficient network use and offers better control over Quality of Service (QoS) settings. Because of its efficiency, it is commonly used in high-performance telecommunication networks that also require security and reliability.

Why MPLS Suits the Airport's Needs

Efficient Data Routing: High-speed, reliable routing supports the multitude of systems within the airport, crucial for real-time operations.

Scalability: MPLS inherently supports scalability, a critical feature for an exponentially growing airport.

Security: MPLS networks seamlessly integrate with various encryption and security protocols.

Convergence and Interoperability: MPLS enables seamless integration of multiple data forms, critical for disparate system operability.

Quality of Service (QoS): Fine-tuning for specific QoS requirements is achievable, and vital for system differentiation.

Future-Proofing: The adaptability of MPLS offers a level of future-proofing against technological advancements.

Enhancing Customer Support with Copper

To adhere to the airport's mission of providing exceptional customer support experience to travelers, Arche implemented its home-grown IVRS customer support solution called Copper. It resulted in effortless and efficient handling of customer requests, reducing wait times and improving overall experience.

We had integrated Copper with AODB through the Information Broker to provide real-time information to the customers.
