Appl. No.:

12/398735

Yang Cao - Westford MA, US
Michael Nicolazzo - Philadelphia PA, US
William M. Turner - Higganum CT, US
Talbot Hack - Ann Arbor MI, US
Moshe Suberri - Voorhees NJ, US

Assignee:

Sycamore Networks, Inc. - Chelmsford MA

International Classification:

G06F 15/16

US Classification:

709218, 709202, 709216, 709217

Abstract:

A method in an electronic device provides local content to a user device in a communication network. The communication network includes an access network and a core network. In the access network, a content request is intercepted from the user device, which may be formatted according to a network interface. The content request may include a request for data content. Protocol layers associated with an active data session may be terminated so that an edge gateway device may extract and inject packets into the data stream without involving the core network. A cache may be maintained in the access network.

H04W 4/00

US Classification:

370225, 370329, 370465

Abstract:

A method in an electronic device and a system for use in a communication network including a core network and at least one access network are described. Intermediate service platforms in an access network process data bound from a base station towards a core network, and vice versa. A first data channel or stream is processed by the intermediate service platform. Exemplary embodiments bypass the intermediate service platform by intercepting a second data channel or stream bound for the intermediate service platform. The data in the second data channel or stream is processed and inserted into a data channel or stream downstream of the intermediate service platform.

Moshe SUBERRI - Voorhees NJ, US

Assignee:

SYCAMORE NETWORKS, INC. - Chelmsford MA

International Classification:

G06F 15/16

US Classification:

709231

Abstract:

A content selection and injection mechanism is provided for a communication network. In the communication network, an electronic device inserts custom data content into a data stream. The electronic device accepts a data stream from a location in the access network and identifies an insertion point suitable for inserting the custom data content into the data stream. The electronic device also selects the custom data content from a local content storage repository located in the access network, and inserts the custom data content into the data stream at the identified insertion point. The electronic device may identify a targeted user for receiving content, and select the custom data content based on the identity of the targeted user.

International Classification:

G06F 12/08

US Classification:

711133, 711E12017

Abstract:

A method for replacing, refreshing, and managing content in a communication network is provided. The method defines an object policy mechanism that applies media replacement policy rules to defined classes of stored content objects. The object policy mechanism may classify stored content objects into object groups or policy targets. The object policy mechanism may also define metric thresholds and event triggers as policy conditions. The object policy mechanism may further apply replacement policy algorithms or defined policy actions against a class of stored content objects. The media replacement policy rules are enforced at edge content storage repositories in the communication network. A computing device for carrying out the method, and a method for creating, reading, updating, and deleting policy elements and managing policy engine operations, are also provided.

International Classification:

G06F 15/16

US Classification:

709203, 709231

Abstract:

A method in an electronic device provides a mechanism for maintaining application mobility in a communication network, such as a content distribution network. In one exemplary embodiment, a user device transitions from a source content server in a first access network of the communication network to a destination content server in a second access network of the communication network. The source content server hands off responsibility for serving the content to the destination content server. In some embodiments, a tunnel is created between the source content server and the destination content server.
