    摘要: A system for managing and distributing a blacklist of User Equipment IDs (UE IDs) in a network. The system comprises a number of groups of networks, each of the groups of networks comprise a blacklist server and a number of authentication servers. The system further comprises a Package Key Generator (PKG). The blacklist server is configured to: store a blacklist containing UE IDs that are not allowed to gain access to the network; transmit the blacklist to the plurality of authentication servers in the same group; receive a message; determine a content in the message is an order to add a new revoked UE ID to the blacklist; update the blacklist to include the new revoked UE ID; and send an update blacklist message to the plurality of authentication servers in the same group.

    摘要: This invention is related to an Express Traversal (EXTRA) Network on Chip (NoC) comprising a number of EXTRA routers. The EXTRA NoC comprises a Buffer Write and Route Computation (BW/RC) pipeline, a Switch Allocation-Local (SA-L) pipeline, a Setup Request (SR) pipeline, a Switch Allocation-Global (SA-G) pipeline, and a Switch Traversal and Link Traversal (ST/LT) pipeline. The BW/RC pipeline is configured to write an incoming flit to an input buffer(s) of a start EXTRA router and compute the route for the incoming head flit by selecting an output port to depart from the start EXTRA router. The SA-L pipeline is configured to arbitrate the start EXTRA router to choose an input port and an output port for a winning flit. The SR pipeline is configured to handle the transmission of a number of SR signals from the start EXTRA router to downstream EXTRA routers.
