摘要： One embodiment of the present invention provides a system for facilitating network service virtualization. During operation, the system receives a service request from a client, and initializes a communication session with the client. The system constructs an interest using session state information that can identify the client and/or a previous communication session. The interest comprises a hierarchically structured variable-length name. The system then broadcasts the interest to a number of servers. The system subsequently forwards to the client data received from a server which responds first to the interest.

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 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.
摘要翻译：本发明的一个实施例提供了一种便于会话迁移的系统。在操作期间，系统从发往远程服务器的客户端接收通信包。系统确定通信分组是否属于预先存在的通信会话，以及与该会话相关联的会话状态信息是否可在本地获得。响应于属于预先存在的通信会话的通信分组，并且会话状态信息在本地不可用，系统构造了请求会话状态信息的兴趣，通过网络传播兴趣，并且接收会话状态信息。

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 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.
