Distributed Cloud Network Anycast Routing for DDoS Mitigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional on-premises networks are expensive, require significant capital outlays, and are difficult to manage due to the need for multiple hardware components for performance and security, particularly in mitigating distributed denial-of-service (DDoS) attacks.
Innovation Solution
A distributed cloud computing network provides network layer performance and security services without the need for additional hardware or software, using multiple geographically distributed data centers that advertise anycast IP addresses to route IP traffic and offer performance services such as content delivery networks and security services like DDoS protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If enterprises deploy on-premises network services with multiple hardware components for performance and security, then network security and performance are improved, but capital outlays, operational costs, and device complexity increase significantly
Solution Approach 1:
The patent extracts network security functions (DDoS protection, firewalls, load balancing) from on-premises hardware and relocates them to cloud-based virtual network functions. This allows enterprises to maintain security capabilities while eliminating the need for physical hardware appliances, directly resolving the contradiction between security reliability and device complexity
Solution Approach 2:
The patent implements a unified cloud-based platform that provides multiple network functions (security, performance optimization, load balancing) through virtualized services. This multi-functional approach replaces multiple specialized hardware components with a single versatile cloud platform, reducing device complexity while maintaining comprehensive network protection
2Reliability
If enterprises purchase and maintain network function specific hardware equipment, then network performance and security services are provided, but ongoing maintenance costs and operational complexity increase
Solution Approach 1:
The patent implements self-healing and automated management capabilities in the cloud-based virtual network functions. The system automatically detects, isolates, and recovers from failures without requiring manual intervention, eliminating the need for specialized maintenance staff while ensuring continuous network performance
Solution Approach 2:
The patent introduces a cloud-based intermediary layer that manages network functions remotely. This intermediary handles all maintenance, updates, and optimizations centrally, allowing enterprises to maintain high network performance without bearing the operational burden of hardware maintenance
3Reliability
If enterprises rely on a small number of scrubbing centers for DDoS protection, then security against DDoS attacks is improved, but network vulnerability and lack of redundancy increase
Solution Approach 1:
The patent segments DDoS protection capabilities across multiple geographically distributed cloud data centers rather than relying on a few centralized scrubbing centers. This segmentation provides redundancy and ensures that if one location is overwhelmed or compromised, others can continue providing protection, enhancing both reliability and adaptability
Solution Approach 2:
The patent transitions from a single-dimension approach (few scrubbing centers) to a multi-dimensional distributed architecture across numerous cloud data centers. This dimensional expansion provides diverse attack mitigation strategies and geographic redundancy, improving both DDoS protection reliability and adaptability to various attack vectors
Data Source
AI summary
A first computing device of a distributed cloud computing network receives an IP packet that is destined to an origin server of an origin network. The first computing device processes the received IP packet and encapsulates the IP packet inside an outer packet to generate an encapsulated packet, where the outer packet has a source IP address that is advertised as an anycast IP address at the distributed cloud computing network, and a destination IP address of an origin router of the origin network. The encapsulated packet is transmitted to the origin router.
