One embodiment of the present invention provides a system that facilitates delivery of advertisements over a network. The system includes an affiliate node. During operation, the affiliate node receives a content piece from a content provider. The content piece includes a placeholder link associated with a predetermined advertising slot. The affiliate node modifies the content piece by replacing the placeholder link with an advertisement or a link thereto. Subsequently, the affiliate node receives a request for the content piece from a client, and delivers the modified content piece to the client.

Distributed advertisement insertion in content-centric networks

One embodiment of the present invention provides a system for controlling the spread of interests and content in a content centric network (CCN). During operation, the system maintains a routing policy for content data. The system also receives a packet associated with a piece of content or an interest for the content. Next, the system determines that the structured name included in the packet is within the namespace specified in the routing policy. The system further determines that the packet satisfies the condition in the routing policy. Subsequently, the system routes the packet based on in part the action corresponding to the condition as specified in the routing policy.

Controlling the spread of interests and content in a content centric network

One embodiment provides a system that forwards a packet with a hierarchically structured variable-length identifier (HSVLI) in a network. An HSVLI indicates a piece of content and indicates a hierarchical structure of contiguous components ordered from a most general level to a most specific level. The length of the HSVLI is not fixed. During operation, the system receives a packet which contains an interest for a piece of content with an HSVLI. Subsequently, the system determines forwarding information for the HSVLI based on one or more of: knowledge of content which matches the HSVLI, a forwarding policy, and contextual information about the network. Next, the system configures a forwarding engine with the forwarding information. The system then forwards the packet based on the forwarding information.

Adaptive multi-interface use for content networking

A network-connectivity system uses one or more local endpoints to establish a set of directed network connections across network domains. During operation, the system determines a first network domain which is to function as a via that communicates data from other network devices to a predetermined endpoint of a local domain. The system then generates a via-domain description, which references the first network domain as a via for the local domain. The system also determines a second network domain which is to function as a proxy that communicates data to other network domains from a predetermined endpoint of the local domain. The system generates a proxy-domain description, which references the second network domain as a proxy for the local domain. The system then synchronizes the via-domain description with devices of the first network domain, and synchronizes the proxy-domain description with devices of the second network domain.

Method and apparatus for configuring routing paths in a custodian-based routing architecture

A collection-synchronizing system synchronizes a local data collection with a remote device. During operation, the system can detect the remote device, and receives collection summaries for one or more data collections stored at the remote device. A collection summary can include at least one additive hash value that represents one or more content items of a data collection. Then, for a data collection that exists at the local device and the remote device, the system compares a remote additive hash value for the remote data collection with a local additive hash value for the local data collection. If the system determines that the local additive hash value does not match the remote additive hash value, the system synchronizes structured names for the data collection at the local device and the remote device.

Data transport by named content synchronization

A data-firewall system blocks sensitive data from becoming available outside a protected space. During operation, the system can obtain an interest from a requesting entity. The requesting entity can include, for example, a software application running on a local computer, a computing device of an Enterprise environment, or a computing node of a computer cluster. Also, the interest can include a location-independent structured name associated one or more data items. When the system obtains the data associated with the location-independent structured name, the system proceeds to obtain a policy associated with the data, and to determine a context for the interest. Then, if the system determines that the requesting entity is within a protected space, as determined based on the policy and the context, the system forwards the data to the requesting entity.

Information firewall

A network-connectivity system can receive a remote additive hash for a routing-data collection of a remote network node, and compares the remote additive hash with a local additive hash for a local routing-data collection. A respective additive hash represents one or more network-configuration items of a routing-data collection. Also, at least one of the network-configuration items of the routing-data collection includes reachability information for a network node of a computer network, such as a link-state advertisement. If the system determines that the remote additive hash does not match the local additive hash, the system synchronizes the local routing-data collection with the remote network node of the computer network.

Dynamic routing protocols using database synchronization

A system and method identifies topology information of an autonomous system as well as other autonomous systems, and can provide topology information in response to requests.

System and method for identifying network topology information in multiple areas

One embodiment of the present invention provides a system for facilitating custodian-based routing. During operation, the system receives, at a computing device serving as a backup custodian to one or more mobile devices, a request for a piece of content from a requesting device, which has mapped the content to the computing device based on the content's name without using the computing device's physical address. The system determines whether the content is available on the computing device. In response to the content not being available on the computing device, the system identifies a mobile device that stores the content, and obtains the content from the identified mobile device. The system then caches the content on the computing device, thereby enabling the computing device to provide the content in response to subsequent requests without connecting to the identified mobile device, and provides the content to the requesting device.

Energy-efficient content caching with custodian-based routing in content-centric networks

One embodiment of the present invention provides a system for facilitating custodian-based routing. During operation, the system receives, at a computing device, a request for a piece of content from a user, and determines whether the content is available locally. In response to the content not being available locally, the system identifies a remote custodian device that stores the content. The custodian device is not identified by its physical address. The system then identifies a communication endpoint associated with the identified custodian device, and maps a physical address corresponding to the identified communication endpoint. The system establishes a connection to the communication endpoint using the mapped physical address to obtain the requested content.

Custodian-based routing in content-centric networks

A system and method processes messages related to nodes in a network and provides reports according to those messages to allow analysis of the network.

System and method for identifying issues related to messages in a communication network

System and method for identifying network topology information

One embodiment of the present invention provides a system including a mobile device and a content-retrieving agent for facilitating energy-efficient content retrieval. During operation, the mobile device receives a request for a piece of content from a user. In response to the request, the mobile device forwards the request to the content-retrieving agent which is configured to obtain the requested content from a remote device on behalf of the mobile device. The system allows the mobile device's receiver to be placed in an energy-saving sleep mode when the content-retrieving agent is obtaining the requested content for the mobile device and is not transmitting the content to the mobile device. The system allows the mobile device's receiver to wake up when the content-retrieving agent is transmitting the content to the mobile device. The mobile device receives the content from the content-retrieving agent.
