摘要： Control circuitry is coupled between an error event output and a data input of a pseudorandom binary sequence (PRBS) checker. The control circuitry is configured to switch between a first operating state in which a received PRBS signal is applied to the data input of the PRBS checker and a second operating state in which an error signal is applied to the data input of the PRBS checker, responsive to detection of a designated condition of the PRBS checker. In an illustrative embodiment, the designated condition is an end-of-test condition indicating that the PRBS checker has completed a test involving the received PRBS signal.

摘要： The innovation provided an approach to the great volume of data based dynamic policy model, which consists of the steps as the following: 1) User registration in the Differentiation Access & Application Control System (DACS); 2) After user log in Radius system, the user profile is delivered to DACS system where user profile can be recorded; 3) After logging in DACS system, user has option to subscribe the policy for the bandwidth, and the DACS system record the subscribed policy information; 4) User requests to use the subscribed policy via the interface provided by DACS system; 5) After receiving policy requests from user, the DACS system creates a thread which dispatches the policy ordered by subscriber. After finishing above, the result will be returned to subscriber. The innovation supports dynamic policy dispatch in real-time manner for the large number of subscribers, specified bandwidth and QoS according to the service, thus the change from bandwidth control to the dynamic policy model for the service control is realized.

摘要： Disclosed is a system or method of using hash functions to preserve a relationship. A relationship is anonymously preserved by storing the hash result of a relationship token that comprises a finite set of values of a plurality of objects. Specifically, an account anonymous identifier of an account can be produced by hashing a relationship token that comprises identity information of an owner of said account. A party that has enough knowledge of an account owner can independently produces said account anonymous identifier and therefore, securely communicates with a specific account without prior communication or a password. An account owner can further prove his/her ownership of an account by submitting related documents and a relationship token that comprises his/her identity information to an account system.
