Method and system for implementing a version control adaptive architecture platform
Patent No. US10482069 (titled "Method and system for implementing a version control adaptive architecture platform") on Aug 4, 2017. The application was issued on Nov 19, 2019.
What is this patent about?
’069 is related to the field of version control systems and distributed server architectures. Specifically, it addresses the scalability and reliability challenges faced by large-scale Subversion (SVN) deployments where high request volumes and concurrent access to shared file systems often lead to performance bottlenecks, race conditions, and data corruption.
The underlying idea behind ’069 is to decouple the user-facing access point from the physical storage of source code repositories through a multi-tier routing architecture. By utilizing a central lookup table that maps specific repository URLs to dedicated server instances and storage volumes, the system ensures that only one server processes requests for a given repository at any time, effectively eliminating the race conditions inherent in traditional clustered environments.
The claims of ’069 focus on a tiered request-handling structure comprising a global load balancer, a front-end proxy server, and a plurality of backend SVN servers. The core mechanism involves the proxy server parsing a URL to query a lookup table, which identifies the exact storage component and SVN server responsible for that specific repository, ensuring targeted and isolated request processing.
In practice, the system provides a seamless failover mechanism by pairing each production server with a dedicated disaster recovery (DR) instance. These DR servers perform live data monitoring of the production environment, allowing for an automated transition of traffic in the event of a hardware failure or scheduled maintenance. This ensures that developers experience minimal downtime, as the DR server can immediately process requests against the existing live data volumes.
This approach differs from prior solutions by moving away from a single-server model or a loosely managed cluster where multiple hosts compete for the same files. By implementing automated rebalancing based on storage capacity and server load, the architecture can scale horizontally to support thousands of repositories. The use of a persistent global URL ensures that existing build scripts and documentation remain functional even as the underlying backend infrastructure is reorganized or expanded.
How does this patent fit in bigger picture?
Technical Landscape
In the late 2010s when ’069 was filed, source control management was typically implemented using centralized server architectures where a single primary host managed repository access for an entire organization. At a time when systems commonly relied on monolithic server instances to maintain data integrity, scaling these environments to accommodate high-volume global traffic was often constrained by the risk of race conditions occurring when multiple processes attempted to write to the same file system simultaneously. Consequently, hardware and software constraints made achieving high availability and automated failover non-trivial, as disaster recovery often required manual intervention or hot-swap configurations that could not dynamically redistribute active loads without interrupting service continuity.
Prosecution Position
The disclosed architecture achieves a technical advancement in distributed version control by integrating a multi-tier routing logic that decouples user requests from specific backend storage. By utilizing a global load balancer in conjunction with a proxy server that references a specialized lookup table, the system enables an architectural shift from monolithic hosting to a distributed SVN server array where traffic is mapped to specific storage components. This configuration overcomes the technical constraint of write-collision race conditions while enabling a seamless failover capability. The technical effect is a self-healing environment where disaster recovery servers actively monitor live data streams to facilitate automated traffic rerouting, ensuring continuous availability and improved throughput for high-concurrency repository access.
Claims
The patent contains a total of 20 claims, with claims 1 and 11 serving as the independent claims. These independent claims focus on a version control adaptive system and a corresponding computer-implemented method that utilize a global load balancer, a proxy server with a lookup table, and a plurality of Subversion (SVN) servers integrated with disaster recovery servers for automatic failover and traffic rerouting. The dependent claims serve to provide additional technical specifications regarding the nature of failover events, the synchronization and updating of the lookup table, the suspension of backend processes, the specific content of the URLs, the use of Q Trees within the servers, and the automatic load-based rebalancing of repositories.
