Embodiments herein include methods and systems for use in delivering resources to a client device over a local network. An exemplary system comprises a plurality of caching devices operable to cache resources on behalf of a plurality of content providers, and a local caching device communicatively situated between an access network and the client device, wherein the access network is communicably situated between the plurality of caching devices and the local caching device. The local caching device is operable to retrieve a requested resource from at least one of the plurality of caching devices, deliver the requested resource to the client device over the local network, and store the requested resource for future requests by other client devices.

Content delivery network with deep caching infrastructure

An asymmetrical and dynamic routing system (ADRS) is provided to enable the dynamic adjustment of the bandwidth capacity of two or more network devices exchanging data. The two or more network devices monitor their current bandwidth demand between themselves and others in a network and a first network device can transmit bandwidth request to a second network device when the first network device reaches transmission bandwidth capacity. Each network device is further configured with additional transmit and receive ports and can be selectively enabled in response to a bandwidth request from other network devices. Each network device is further configured to generate control signals that are sent to optical mirrors to re-direct data signals to or from the one or more enabled additional transmit and receive ports.

Apparatus, system, and method for asymmetrical and dynamic routing

A method and computer program product are presented for selecting and arranging an appropriate combination of network components, or elements, in a communications network. The selection of network components is done in a manner that maximizes the net present value of cash flow resulting from the provision of communications services between nodes of the network. The method comprises the steps of receiving information that constrains network design and price establishment, and then using the constraint information to select a combination of network components for each link in the communications network. According to the invention, the selection of network components is performed for each of several successive time periods, effectively planning the evolution of the network. The selections are made so that the network components satisfy demand over time while maximizing the net present value of the cash flow that results from the provision of communications services.
