Real-world case studies provide valuable insights into the implementation of advanced networking technologies and offer lessons learned from both successful and failed networking projects. Here are some examples:
Case Study 1: Google’s SDN Implementation (Success)
- TechnologySoftware-Defined Networking (SDN)
- DescriptionGoogle adopted SDN to manage its global network, which spans data centers and interconnects with the public internet. Google’s network infrastructure is based on its custom SDN platform called Espresso.
- Lessons LearnedGoogle’s SDN implementation improved network agility, reduced latency, and optimized traffic routing. The key takeaway is that SDN can bring significant benefits to large-scale networks by centralizing control and enabling dynamic routing.
Case Study 2: Target’s Data Breach (Failure)
- TechnologyNetwork Security
- DescriptionIn 2013, Target suffered a massive data breach in which hackers stole credit card information from millions of customers. The breach was the result of inadequate network security and failure to detect suspicious activity.
- Lessons LearnedThe Target breach underscores the critical importance of robust network security measures, including intrusion detection and prevention, regular security audits, and employee training.
Case Study 3: AT&T’s ECOMP Platform (Success)
- TechnologyNetwork Orchestration and Virtualization
- DescriptionAT&T developed the Enhanced Control, Orchestration, Management, and Policy (ECOMP) platform to automate network service orchestration and management. ECOMP played a pivotal role in AT&T’s transition to a software-centric network.
- Lessons LearnedECOMP’s success demonstrates the benefits of network orchestration in improving network agility, reducing operational costs, and accelerating service deployment.
Case Study 4: British Airways’ IT Outage (Failure)
- TechnologyIT Infrastructure
- DescriptionIn 2017, British Airways suffered a major IT outage that led to flight cancellations and passenger disruptions. The outage was attributed to a failure in the airline’s IT infrastructure.
- Lessons LearnedThe British Airways incident highlights the importance of robust IT infrastructure, disaster recovery plans, and the need for redundancy to prevent system failures.
Case Study 5: SpaceX’s Starlink (Success)
- TechnologySatellite Internet
- DescriptionSpaceX’s Starlink project aims to provide global internet coverage via a constellation of low Earth orbit (LEO) satellites. Starlink uses advanced networking technology to deliver high-speed internet access to remote and underserved areas.
- Lessons LearnedStarlink demonstrates the potential of advanced networking technologies, including satellite internet and LEO constellations, to bridge the digital divide and connect remote regions.
Case Study 6: Equifax Data Breach (Failure)
- TechnologyNetwork Security
- DescriptionIn 2017, Equifax experienced a massive data breach that exposed sensitive personal information of millions of consumers. The breach resulted from a failure to patch a known security vulnerability.
- Lessons LearnedThe Equifax breach underscores the importance of regular security patching, vulnerability management, and proactive security measures to protect sensitive data.
These case studies illustrate the real-world impact of advanced networking technologies and the critical role of effective network management, security, and resilience. They provide valuable lessons for organizations seeking to leverage advanced networking technologies while avoiding pitfalls and vulnerabilities.
Key terms in plain language
Open a term for a concise explanation of language used on this page.
Fiber Internet
Internet delivered through strands of glass using light. Fiber commonly supports high capacity, low latency, and strong upload performance, but availability must be confirmed for the exact address.
Latency
The time it takes data to travel between two points. Lower latency improves voice, video meetings, cloud applications, gaming, and other real-time services.
Disaster Recovery (DRaaS)
A plan and service for restoring applications, data, and operations after an outage or disruption. DRaaS provides recovery infrastructure through a managed cloud service.
Cybersecurity
The practices and controls used to protect identities, devices, networks, applications, and data from unauthorized access, disruption, or manipulation.
Zero Trust
A security model that does not automatically trust a user or device because of its location. Access is continuously verified and limited to what is necessary.
SASE
Secure Access Service Edge combines networking and security capabilities in a cloud-delivered architecture so users and locations can receive consistent policy wherever they connect.
