At a router, at least one memory and computer program code stored therein are configured to, with at least one processor, cause the router to: determine source router identification information for a tunnel traversing the router based on a routable source IP address for the tunnel; determine destination router identification information for the tunnel based on a routable destination IP address for the tunnel; program a bit string entry for the tunnel in a Bit Index Forwarding Table (BIFT) for tunnels from a source router to a plurality of destination routers, the BIFT being indexed based on the source router identification information and at least a portion of the destination router identification information; and route packet data received at the router according to the BIFT.

A method for synchronizing topology information in a service function chain (SFC) network, where the SFC network includes at least one classifier (CF) and at least one service function forwarder (SFF). The method includes that a first network element in the at least two routing network elements establishes a Border Gateway Protocol (BGP) connection to at least one second network element other than the first network element in the at least two routing network elements, where the first network element is any one of the at least two routing network elements, and the first network element sends a first BGP update message to the at least one second network element, where the first BGP update message includes topology information of the first network element such that the at least one second network element obtains the topology information of the first network element.

A method is performed by a first server on a chip (SoC) node that is one instance of a plurality of nodes within a cluster of nodes. An operation is performed for determine if a second one of the SoC nodes in the cluster has data stored thereon corresponding to a data identifier in response to receiving a data retrieval request including the data identifier. An operation is performed for determining if a remote memory access channel exists between the SoC node and the second one of the SoC nodes. An operation is performed for access the data from the second one of the SoC nodes using the remote memory access channel after determine that the second one of the SoC nodes has the data stored thereon and that the remote memory access channel exists between the SoC node and the second one of the SoC nodes.

Generally discussed herein are systems, devices, and methods for data management in a reverse content data network (rCDN). A component of the rCDN may include a memory to hold content received from a first sensor device of a plurality of sensor devices of the rCDN and first attributes that describe properties of the content. The component may include processing circuitry to receive second content from a second sensor device of the plurality of sensor devices, the second content including a plurality of second attributes that describe properties of the second content, and forward, in response to a determination, based on the first and second attributes, that there is insufficient space to store the second content on the memory, the second content to a node of the rCDN that is fewer hops away from a backend cloud than the component.

This application provides a router. A shielding portion is formed by extending outward an end of a housing where a rotary shaft seat is disposed. The rotary shaft seat is disposed on a side of the shielding portion facing a back of the housing. An end of the shielding portion away from the housing extends to at least a side of the rotary shaft seat away from the housing, so as to shield a front of the rotary shaft seat. In this way, the rotary shaft seat is invisible in a conventional viewing angle, that is, a viewing angle from a front of the router.
