Abstract:
Provided are a method and apparatus for content delivery networking. There is provided a method of managing a content delivery network to transfer media content to a user, including: receiving a network configuration request and network configuration information, from a service provider that provides the content; receiving resource information including information about available resources required for configuring the network; and configuring a content delivery overlay network, based on the resource information and the network configuration information. Therefore, by configuring a content delivery overlay network for each provider, service and content providers having no unique content delivery method of their own can provide multimedia services based on applications for smart TV and web TV to a plurality of users.

Plain-Language Overview of Independent Claims

U.S. Patent 9,112,934 contains two independent claims, one directed to an apparatus and the other to a method.

Independent Claim 1 (Apparatus): This claim describes a physical system for managing a content delivery network (CDN). The system is designed to receive a request from a service provider (like a streaming service) to set up a network for delivering their content. This request includes specific information about the network they need. The system also manages information about the available network resources (like servers and bandwidth). Based on the provider's request and the available resources, a controller within the system sets up a specific "transfer path" using multiple network nodes. This path creates a temporary, customized "overlay network" that delivers the content from its source to the end-user's device.

Independent Claim 7 (Method): This claim outlines the process that the apparatus in Claim 1 performs. The method involves three main steps:

1. Receiving a request and network requirements from a content provider.
2. Gathering information about the available network resources.
3. Using this information to configure a delivery path for the content through a series of network nodes, creating a temporary and efficient "overlay network" to deliver the content to the user.

A search of the U.S. Court of Appeals for the Federal Circuit (CAFC) 2026 dockets did not yield any results for litigation involving U.S. Patent 9,112,934 as of the date of this analysis. However, this does not authoritatively preclude the existence of litigation in other venues or outside of the specified timeframe.
