Abstract: Techniques for implementing multi-table OpenFlow using a parallel hardware table lookup architecture are provided. In certain embodiments, these techniques include receiving, at a network device from a software-defined networking (SDN) controller, flow entries for installation into flow tables of the network device, where the flow entries are structured in a manner that assumes the flow tables can be looked-up serially by a packet processor of the network device, but where the flow tables are implemented using hardware lookup tables (e.g., TCAMs) that can only be looked-up in parallel by the packet processor. The techniques further include converting, by the network device, the received flow entries into a format that enables the packet processor to process ingress network traffic correctly using the flow entries, despite the packet processor's parallel lookup architecture, and installing the converted flow entries into the flow tables/hardware lookup tables.

Abstract: A system adaptably directs packet flows to packet processing elements based on OSI layer characteristics and, when necessary, inspection of data payloads. Characteristics of parsed data flows are identified. A comparison ensues. Upon recognition of a match, the entirety of the packet flow is directed to a linked packet processing element. When a match does not occur, the packet flow is directed to a second analysis tier whereby data payloads of the flow are examined. Characteristics from the data payload analysis are compared to entries in a database. Upon a match being recognized the matching packet flow is directed to the packet processing element. Features of packet flow having undergone data payload analysis are captured and used to update the database of prior associations so that any subsequent receipt of similar packet flows will be forwarded to the linked packet processing element without having to conduct a data payload analysis.

Abstract: Generally, the described techniques provide for a user equipment (UE) generating a scheduling request (SR) for a set of data for an uplink transmission from the UE to a base station. The UE may determine whether the SR for the set of data is associated with a grant-free configuration for the UE. The grant-free configuration may indicate a set of time-frequency resources that the UE may use to transmit the set of data. The UE may transmit to the base station an indication of whether the SR is associated with the grant-free configuration. If the SR is associated with a grant-free configuration for the UE, the UE may use the corresponding resources to transmit the set of data to the base station, and the base station may then decode the data based on having received the indication of the resources by way of the grant-free configuration.

Abstract: A method and apparatus decode packetized data in the presence of packet erasures using a finite sliding window technique. A decoder receives packets containing uncoded and coded symbols. When a packet with a coded symbol is received, the decoder determines whether a packet sequence number is within a sliding window of w consecutive sequence numbers that are no greater than a decoder sequence number, where the number w is fixed prior to encoding. When this is the case, the decoder decodes the coded symbol into one or more of the w input symbols using the coefficient vector. Decoding may use a forward error correcting (FEC) window within the finite sliding window. Decoding also may use a technique of Gaussian elimination to produce a “shifted” row echelon coefficient matrix.

Abstract: In a case that a network (NW) applies a plurality of congestion controls, various kinds of congestion control identification information along with a back-off timer (Session Management (SM) timer) are notified such that a terminal apparatus (UE) can apply a congestion control expected by the NW. Alternatively, in a case that the UE receives an NW-initiated SM request with the back-off timer activated, the UE is allowed to identify an SM timer intended by the NW-initiated SM request. Alternatively, in a case that the UE receives the NW-initiated SM request with the back-off timer activated, the UE is allowed to modify the association of the activated back-off timer and the congestion control to be applied. Thus, a communication control method for the terminal to apply the congestion control expected by the NW in the congestion controls applied by the NW in 5G congestion control that applies a plurality of congestion controls is provided.
