摘要： 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.

摘要： 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.

摘要： One embodiment provides a system for forwarding packets with hierarchically structured variable-length identifiers (HSVLIs), wherein the computer includes a processor. During operation, the system converts an HSVLI into a number of fixed-length addresses, wherein the HSVLI indicates a piece of content and is hierarchically structured, and comprises contiguous components ordered from a most general level to a most specific level. In addition, the length of a respective HSVLI is not fixed. The system further performs an effective longest-prefix-match lookup by performing multiple exact-match lookups based at least on the fixed-length addresses.

摘要： 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.

摘要： One embodiment provides a system that receives a packet with a hierarchically structured variable-length identifier (HSVLI). An HSVLI indicates a piece or collection of content and may be hierarchically structured, comprising contiguous components ordered from a most general level to a most specific level. The length of a respective identifier is not fixed. During operation, the system converts the HSVLI into a fixed-length key. Subsequently, the system obtains forwarding information based on one or more longest-prefix matches with a longest-prefix-match lookup engine using the fixed-length key. Next, the system forwards the packet to an output port based on the forwarding information.

摘要： One embodiment of the present invention provides a system for facilitating session migration. During operation, the system receives a communication packet from a client destined to a remote server. The system determines whether the communication packet belongs to a pre-existing communication session, and whether session state information associated with the session is available locally. In response to the communication packet belonging to a pre-existing communication session and the session state information being unavailable locally, the system constructs an interest requesting the session state information, disseminates the interest over a network, and receives the session state information.

摘要： One embodiment of the present invention provides a system for facilitating communication in a content centric network (CCN). During operation, the system receives at a first node from an interest owner an interest in a piece of content. The interest indicates a structured name for the content. Furthermore, the name is unique and persistent with respect to the content, and where the name includes authentication information for the content. Next, the system determines whether content available at the first node satisfies the interest. If so, the system sends the content to the interest owner. Otherwise, the system marks the interest as pending, and forwards the interest to a second node in the network based on the interest. After receiving content from the second node in response to the forwarded interest, the system un-marks the interest as pending and sends the content to the interest owner.
摘要翻译：本发明的一个实施例提供了一种促进内容中心网络（CCN）中的通信的系统。在操作期间，系统在兴趣所有者的第一节点处接收对一条内容的兴趣。兴趣表示内容的结构化名称。此外，该名称对于内容是唯一的和持久的，并且其名称包括内容的认证信息。接下来，系统确定在第一节点处可用的内容是否满足兴趣。如果是这样，系统将内容发送给兴趣所有者。否则，系统将兴趣标记为待处理，并且基于兴趣将兴趣转发到网络中的第二节点。在从第二节点接收到转发的兴趣的内容之后，系统将兴趣标记为待处理，并将内容发送给兴趣所有者。

摘要： 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.
