摘要： Provided is a high speed bit stream data conversion circuit that includes input ports to receive first bit streams at a first bit rate. Data conversion circuits receive the first bit streams and produce second bit stream(s), wherein the number and bit rate of the first and second bit stream(s) differ. Symmetrical pathways transport the first bit streams from the input ports to the data conversion circuits, wherein their transmission time(s) are substantially equal. A clock distribution circuit receives and symmetrically distributes a clock signal to data conversion circuits. A central trunk coupled to the clock port and located between a first pair of circuit pathways with paired branches that extend from the trunk and that couple to the data conversion circuits make up the clock distribution circuit. The distributed data clock signal latches data in data conversion circuits from the first to the second bit stream(s).

摘要： A method and a system for network access control are provided, which are based on cipher code mechanism. After a visitor has raised an access request, an access controller in the destination network processes the access request and initiates an authentication request on the visitor identity to an authentication server through the visitor. The access controller in the destination network accomplishes the authentication on the visitor identity according to the public authentication result of the authentication server transferred by the visitor, and performs according to the authorization policy the authorization management on the successfully authenticated visitor. The present invention solves the problem of incapableness of performing the access control when the access controller can not directly use the authentication service provided by the authentication server. The present invention can sufficiently satisfy the real application requirements of access control on visitor.

摘要： This invention relates to a peer-to-peer access control method of a triple-unit structure for safely implementing bidirectional authentication between the terminal and the network. According to the method, on the basis of the access control method of the existing double-unit triple-entity structure, the authenticator function is implemented in the access controller, and the authentication protocol function is implemented in the terminal and the access controller, so that the terminal, the access controller and the server all participate in the authentication, and the trust relationship is established between the terminal and the access controller directly, which renders security very reliable. The invention not only solves the technical problems of the access control method of the existing double-unit double-entity structure that the access flexibility is limited and the extension of the number of the access controllers is inconvenient, but also solves the technical problems of the existing access control method of the double-unit triple-entity structure that the process for establishing the trust relationship is complicated and the security of the network may be influenced, thus achieving advantages of high security performance, no requirement of changing existing network structures and relative independency of the authentication protocol.

摘要： Embodiments of a summer block for a Decision Feedback Equalizer are provided herein. The summer block is configured to offset a combination of a Feed Forward Equalized (FFE) data signal and a Feedback Equalized (FBE) data signal by a dc amount: The dc amount is based on at least a weight of a tap previously implemented with an FBE of the DFE. The summer block can be further configured to offset the combination of the FFE data signal and the FBE data signal based on a dc offset value necessary to compensate for asymmetries in the data eye of data received by the FFE over a channel and a dc offset value necessary to compensate for mismatches present in the circuits of the DFE.
