    Abstract: A method implemented in a network element (NE) configured to operate in an information centric network (ICN), comprising receiving an Interest packet through an interface, wherein the Interest packet comprises an in-packet bloom filter and at least one counting filter associated with an element of the in-packet bloom filter; determining an outbound interface to forward the Interest packet to a next hop in the ICN; selecting a local bloom filter based on a mapping of the interface to the local bloom filter; updating a value for the in-packet bloom filter based on a product determined by a bitwise OR operation of the local bloom filter and the in-packet bloom filter; incrementing the at least one counting filter based on a change to the associated element of the in-packet bloom filter; updating the in-packet bloom filter in the Interest packet; updating the at least one counting filter in the Interest packet; and forwarding the Interest packet through the outbound interface.

    Abstract: A method implemented by a first content network element (NE) in an information centric network (ICN), the method comprising receiving, by a receiver, an interest packet through a first interface, wherein a header of the interest packet comprises a path filter, the path filter being associated with one or more segments on a path from a consumer to a producer, modifying, by a processor coupled to the receiver, the path filter based on information identifying one or more previous content NEs or one or more next content NEs on the path to produce a modified path filter, and transmitting, by a transmitter coupled to the receiver, the interest packet with the modified path filter to the next content NE.

    Abstract: Aspects of the disclosure provide a network device that includes interface circuitry and processing circuitry. The processing circuitry is configured to receive a first interest packet carrying a first name, add an indicator for routing look-ahead in the first interest packet to generate a first updated interest packet, and select a first entry in a forwarding information base (FIB) based on a lookup in the FIB for matching entries to the first name. The first entry is indicative of an outgoing interface circuit. The processing circuitry is configured to forward the first updated interest packet via the outgoing interface circuit, and receive a data packet in response to the first updated interest packet. The data packet carries forwarding information of devices that forward the first updated interest packet. The processing circuitry is configured to store the forwarding information of the devices in the first entry.

    Abstract: A method implemented by a network element (NE), comprising obtaining a first mapping between a first content name identifying a content data in a content centric network (CCN) and a first hash value of at least a portion of the first content name, wherein the first content name comprises a character string in a hierarchical namespace, receiving, via a receiver of the NE, an initial packet comprising an initial hash value from the CCN, determining, via a processor the NE, that the initial hash value in the received initial packet matches the first hash value in the obtained first mapping, replacing, via the processor, the initial hash value in the received initial packet with the first content name in the matched first mapping to produce a translated initial packet, and forwarding, via a transmitter of the NE, the translated initial packet comprising the first content name to a connected end host.

    Abstract translation: 一种由网元（NE）实现的方法，包括获得识别内容中心网络（CCN）中的内容数据的第一内容名称和所述第一内容名称的至少一部分的第一哈希值之间的第一映射，其中 所述第一内容名称包括分级命名空间中的字符串，经由所述NE的接收者接收包括来自所述CCN的初始哈希值的初始分组，经由所述处理器确定所述接收到的所述初始哈希值的所述NE 初始包匹配获得的第一映射中的第一散列值，经由处理器将匹配的第一映射中具有第一内容名称的接收到的初始包中的初始散列值替换为产生翻译的初始包，并且经由 NE的转发器，将转换的初始分组包括第一内容名称连接到主机。
