Abstract: Methods and systems are provided for generating a traffic simulation respective of at least one content storing server, the content storing server operative for caching popular content. One method includes sniffing traffic between at least a first portion of a network and at least a second portion of the network, identifying, from the sniffed traffic, at least a source of content and at least a destination of the content, determining if the content is stored on a cache, simulating a notification respective of the content, and generating a simulation of traffic respective at least of: the content and the simulated notification.

Abstract: A computerized method of delivering popular content of a service delivery apparatus (SDA) in an asymmetrical network topology. The method comprises receiving a first acquisition request for content from a user node (UN) over an upstream data link, the request comprising at least a content identification (CID). An instruction is sent to the UN to redirect content requests to the SDA. A second acquisition request is sent from the SDA to a content source (CS) for the content requested by the first acquisition request, upon determination that the downstream data link between the UN and the CS is inaccessible to the SDA, the request including at least the CID. The content is received by the SDA from the CS. The received content from the SDA is sent to the UN.

Abstract: An apparatus comprising a network interface to at least a first portion of a network and at least a second portion of a network. A deep-packet-inspection (DPI) unit identifies at least a source of content, the DPI unit further inspecting one or more packets provided from the identified at least a source of content over the first portion of the network, each packet having at least a specific source address and a specific destination address. A storage stores at least a portion of the content.

Abstract: A method for identification of popular content provided over a first portion of a network to a second portion of a network in the form of packets containing, the method comprises identifying a source of content in the first portion of a network. Deep-packet-inspection (DPI) is performed to determine if content in each packet related to the content is to be stored in a storage that is in a path between the content source and at least a user node in the second portion of the network. The content is stored. A request is received from the user node for a requested content. It is determined if the requested content or portions of the requested content is in the storage. if the requested content or portions of the requested content is missing in the storage, a request is sent to the content source for the requested content or missing portions of the requested content.

Abstract: An apparatus including a network interface to a first portion of a network and a second portion of a network. A deep-packet-inspection (DPI) unit identifies a content source, inspects one or more packets provided from the identified source over the first network portion, each packet having a source address and a destination address. A storage stores at least a portion of the content. A content delivery unit receives a request from the second network portion for requested content from the identified source and responsive thereto provides the requested content, or portions of the requested content, from the storage to the second network portion if the requested content, or a portion of the requested content, is stored in the storage, or otherwise sends the request over the first network portion to the identified source for the requested content, or missing portions of the requested content.

Abstract: A method for identification of popular content provided over a first portion of a network to a second portion of a network in the form of packets containing, the method comprises identifying a source of content in the first portion of a network. Deep-packet-inspection (DPI) is performed to determine if content in each packet related to the content is to be stored in a storage that is in a path between the content source and at least a user node in the second portion of the network. The content is stored. A request is received from the user node for a requested content. It is determined if the requested content or portions of the requested content is in the storage. if the requested content or portions of the requested content is missing in the storage, a request is sent to the content source for the requested content or missing portions of the requested content.
