CDN Resource Routing via IPv6 Granular Addressing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current content delivery networks face limitations in resource-level control and granularity, particularly with IPv4, which restricts operational and business decision-making and lacks a common control plane for inter-CDN communication, leading to inefficiencies in resource management and customer experience.
Innovation Solution
The implementation of a network protocol with enhanced addressing space using IPv6 for granular resource route mapping, allowing for more precise advertisement and management of resources within CDNs, enabling resource affinity, dynamic balancing, and zero-touch provisioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If IPv4 addressing is used in content delivery networks, then compatibility with existing infrastructure is maintained, but resource-level control and granularity are limited
Solution Approach 1:
The patent transitions from IPv4 to IPv6 addressing, changing the fundamental parameter of address space from 32-bit to 128-bit. This enables fine-grained resource-level control by allowing unique addressing of individual content resources, CDN nodes, and delivery paths, thereby resolving the contradiction between adaptability and complexity through a parameter transformation.
2Adaptability or versatility
If traditional CDN architecture is used, then implementation simplicity is maintained, but operational flexibility and resource management efficiency are reduced
Solution Approach 1:
The patent segments the CDN architecture into distinct functional components including origin servers, edge caches, delivery networks, and control planes. This segmentation enables independent optimization and management of each component, providing operational flexibility while maintaining overall system simplicity through modular design.
Solution Approach 2:
The patent introduces a new dimension of control by implementing a separate control plane that operates independently from the data plane. This dimensional separation allows for sophisticated resource management, dynamic routing, and operational flexibility without complicating the actual content delivery path, resolving the contradiction between adaptability and complexity.
3Productivity
If coarse-grained resource management is used, then system simplicity is maintained, but customer experience and resource allocation efficiency deteriorate
Solution Approach 1:
The patent implements local quality by enabling fine-grained control at each CDN node and resource level. Each edge cache, origin server, and delivery path can be independently optimized and managed based on local conditions such as customer demand, network status, and resource availability, thereby improving resource allocation efficiency without requiring centralized complex management.

AI summary
Apparatus and methods for managing content delivery in a packetized network. In one embodiment, the network provide content to a plurality of clients via a plurality of nodes and origin points, and resources are discreetly represented (e.g., with IP addresses, such as those afforded under the IPv6 protocol) to allows for direct advertisement of resources. Exemplary solutions described herein further advantageously leverage extant architectures and protocols (such as BGP), and make use of a common control plane, which can be utilized for example by different content delivery network (CDN) operators and different delivery components to advertise resources. Internally within a given CDN, increased granularity of resource addressing and advertisement may provide benefits including: (i) resource affinity; (ii) resource-level balancing; (iii) dynamic resource scoping; and (iv) “zero-touch” provisioning and resource relocation.
