  • Patent number: 9756081
    Abstract: Methods and systems for improving accuracy, speed, and efficiency of context-aware pattern matching are provided. According to one embodiment, a packet stream is received by a first stage of a CPMP hardware accelerator of a network device. A pre-matching process is performed by the first stage to identify a candidate packet that matches a string or over-flow pattern associated with IPS or ADC rules. A candidate rule is identified based on a correlation of results of the pre-matching process. The candidate packet is tokened to produce matching tokens and corresponding locations. A full-match process is performed on the candidate packet by a second stage of the CPMP hardware accelerator to determine whether it satisfies the candidate rule by performing one or more of (i) context-aware pattern matching, (ii) context-aware string matching and (iii) regular expression matching based on contextual information, the matching tokens and the corresponding locations.

  • Patent number: 9743432
    Abstract: Uplink waveforms for operating long term evolution (LTE) in an unlicensed band (i.e., long term evolution-unlicensed (LTE-U) communication) are disclosed. Carrier aggregation (CA) and standalone (SA) are disclosed. LTE on the licensed channel may provide both control and data, LTE on the unlicensed channel may provide data. Managing variable transmission time interval (TTI) continuous transmission is disclosed for transmission over multiple subframes of an unlicensed carrier in LTE-U. Listen-before-talk (LBT) requirements of unlicensed carriers provide for additional channel occupancy constraints when scheduling resources for multiple UEs for variable TTI continuous uplink transmissions over multiple subframes. A joint control channel is disclosed that provides control information for all of the potentially available subframes to be scheduled for the uplink transmissions.

  • Patent number: 9729474
    Abstract: A method includes, in a wireless data network, monitoring communication conditions at an intermediate location between a wireless communication terminal and a network element that provides voice-call services over the network to the wireless communication terminal. Upon detecting that the communication conditions are expected to cause the wireless communication terminal to send a notification to the network element, an early notification is sent to the network element on behalf of the terminal. Another method includes detecting a notification in which a terminal notifies a network element of degraded reception performance. A modification, which the network element is expected to perform in a transmission characteristic to the terminal in response to the notification, is predicted. In-flight communication traffic, which is en-route to the terminal and whose transmission characteristic is not yet modified in response to the notification, is intercepted.

  • Patent number: 9722943
    Abstract: Seamless path switching is made possible in a multi-hop network based upon stream marker packets and additional path distinguishing operations. A device receiving out-of-order packets on the same ingress interface is capable of determining a proper order for the incoming packets having different upstream paths. Packets may be reordered at a relay device or a destination device based upon where a path update is initiated. Reordering packets from the various upstream paths may be dependent upon a type of service associated with the packet.

  • Patent number: 9699051
    Abstract: A method for measuring one-way link delay includes transmitting a first packet from a first network device. The first packet is passively intercepted, a first copy of the first packet is transmitted to the first network device, and a second copy of the first packet is transmitted to a second network device. A time of receipt of the first copy of the first packet is recorded as an origin timestamp at the first network device. A time of receipt of the second copy of the first packet is recorded as a receive timestamp at the second network device. A second packet including the origin timestamp is transmitted from the first network device. The second packet is passively intercepted, and a first copy of the second packet is transmitted to the second network device. The first copy of the second packet is received at the second network device, and the origin timestamp is extracted from the first copy of the second packet.
