  • Patent number: 11159481
    Abstract: A method is performed by a master network device among network devices of a cluster. The master network device receives cluster configuration information including a set of Internet Protocol (IP) addresses and a pool of port blocks associated with the IP addresses. Each port block includes multiple ports, and the pool of the port blocks is to be shared across the network devices for port address translation. The master network device divides the port blocks in the pool into multiple buckets. The master network device allocates to each network device in the cluster a corresponding one of the buckets, and reserves each bucket that is not allocated for allocation to a potential new network device. When a new network device joins the cluster, the master network device allocates to the new network device the port blocks from a corresponding one of the reserved buckets.

  • Publication number: 20210104266
    Abstract: The present disclosure is directed to efficient memory activation at runtime. A memory module (e.g., a memory riser) being added to a device would typically cause the device to enter system management mode (SMM) to activate the memory module. However, activation (e.g., memory module initialization, hardware training and system reconfiguration) in SMM may substantially delay the resumption of normal operations. Consistent with the present disclosure, at least the memory module initialization and hardware training portions of the activation may be performed by an operating system (OS) in the device, allowing normal device operation to continue during the activation. The OS portion of the activation may generate configuration data. In at least one embodiment, the configuration data may be applied for use in SMM. For example, a system management interrupt (SMI) handler may apply the configuration data during a quiescent period (e.g., a period of inactivity) that occurs during SMM.

  • Publication number: 20210105219
    Abstract: In one embodiment, a network security device configured to monitor a communication session between a first device and a second device generates a first empty acknowledgment packet specifying a first sequence number and sends the first empty acknowledgment packet to the first device. The network security device may thereafter determine that a response from the first device has not been received within a threshold amount of time and generate, at least partly in response, a second empty acknowledgment packet specifying a second sequence number. The network security device may send the second empty acknowledgment packet to the first device and receive, from the first device, a third empty acknowledgment packet specifying a third sequence number. The network security device may then store the third sequence number in association with the communication session between the first device and the second device.
