  • Software upgrade and downgrade using ghost entries
    Patent number: 11068253
    Abstract: Methods and systems for modifying software programs are disclosed. For instance, an example method for modifying a software program may include extracting, from a configuration program file, a future list of one or more future active entries relating to a future version of the software program and a future list of one or more future ghost entries relating to the future version of the software program, comparing the future lists of future active and ghost entries to current lists of current active entries and current ghost entries of a current version of the software program. Then, at least one upgrade or at least one downgrade of the current version of the software program is performed in response the comparison of the current and future lists.
    Type: Grant

  • Filtering of packets for packet types at network devices
    Patent number: 10348684
    Abstract: Examples include a network device to filter a packet for a packet type. The network device includes a filter to receive the packet and to determine whether the packet is a defined packet type. The network device also includes a Bloom filter to receive the packet from the filter based on the determination that the packet is a defined packet type and to determine whether the packet is a matched packet or an unmatched packet. A processing resource of the network device may receive the packet from the Bloom filter based on the determination that the packet is a matched packet and to determine whether the packet is an exact match.
