Method, apparatus, and system for implementing a content switch
Some embodiments provide a novel content switching method that distributes requests for different types of content to different sets of content servers. In some embodiments, the method deploys a content switch in the ingress data path of a first content server that is part of a first set of servers that processes requests for a first type of content.

On the other hand, if the request is for a second type of content that is processed by a second set of servers, the content switch identifies a second content server in the second set and forwards the request to the second content server. When the second set of servers includes two or more servers, the content switch in some embodiments performs a load balancing operation to distribute the load amongst the servers in the second set. For each request, the load balancing operation in some embodiments selects one server from the second server set based on a set of load balancing criteria that specifies one manner for distributing the requests among the servers of the second set, and then forwards the request to the selected server. |

Exercising security control point (SCP) capabilities on live systems based on internal validation processing

Access network dual path connectivity
A transport network employs dual homing to an access network to provide connectivity from multiple network switches. Dual homing is a mechanism by which an access network employs pair of switches in the transport network as if it were connecting to a single device. Conventional arrangements for defining multiple paths from a transport network to an access network suffer from the shortcomings of potential routing loops, increased hops to the access network, and inability or inconsistency with forwarding to different types of access networks, and may involve redirecting traffic absent faults in the access network. The dual homed network switches identify the type of access network and perform switching logic corresponding to the access network type to provide comprehensive dual-homed support to the access network independently of the type of transport employed in the access network, and employ redirection only if there is a fault in the access network. |

A feedback divider in a mixed-signal circuit is modulated by a frequency control word controlling a delta-sigma modulator.

Quantum information processing with majorana bound states in superconducting circuits
In a weak link of two s-wave superconductors (SCs) coupled via a time-reversal-invariant (TRI) topological superconducting (TSC) island, a Josephson current can flow due to Cooper pairs tunneling in and out of spatially separated Majorana Kramers pairs (MKPs), which are doublets of Majorana bound states (MBSs). The sign of the resulting Josephson current is fixed by the joint parity of the four Majorana bound states that make up the MKPs on the TSC island. This parity-controlled Josephson effect can be used as a read-out mechanism for the joint parity in Majorana-based quantum computing. For a TSC island with four terminals, the SC leads can address a Majorana superconducting qubit (MSQ) formed by the charge ground states of the TSC island's terminals. Cooper pair splitting enables single-qubit operations, qubit read-out, as well as two-qubit entangling gates.
