  • Patent number: 10051006
    Abstract: Latency-based timeouts are used for concurrent security processing by multiple in-line network security tools. A network system forwards secure network packets to the tools and uses latency-based timeouts with respect to the return of processed packets from the tools. Initially, the network system measures processing latencies for the tools and sets at least one timeout threshold based upon the processing latencies. The network system then receives an input packet from a network source, generates a timestamp, concurrently sends an output packet to the tools based upon the input packet, tracks return packets from the tools, and determines whether a timeout has occurred with respect to the timeout threshold based upon a difference between the timestamp and a current timestamp. If a timeout does not occur, a secure packet is forwarded to a network destination. If a timeout does occur, return packet tracking for the input packet is ended.

  • Patent number: 9918265
    Abstract: One aspect of the teachings herein involves the temporary transfer of radio identities from one service area of a wireless communication network to another service area, where the individual radio identities are used to differentiate individual radio connections between the network and respective wireless nodes supported by the network. In particular, the temporary transfer of a given radio identity from its default service area for use in another service is limited temporally and/or geographically. Limiting the temporal and/or geographic scope of the radio identity transfer allows the network to substantially maintain default associations of radio identities and their respective service areas, which allows the network to prevent or reduce the use of conflicting radio identities in the same service area. Transfer signaling may be used transfer radio identities, and such signaling may include the temporal and/or geographic restrictions, to control the migration or spread of borrowed identities in the network.
