  • Publication number: 20190335331
    Abstract: A method, an apparatus, and a system for performing authentication on a terminal in a wireless local area network are provided. The method uses a feature code as a part of an authentication credential. The feature code is a function of capability parameters of a terminal. The feature code can identify the terminal, so that the authentication server determines the authentication result based on a MAC address and the feature code of the terminal.

  • Publication number: 20190319918
    Abstract: The method for a virtual machine to use a port and loopback IP addresses allocation scheme for full-mesh communications with transparent transport layer security tunnels is presented. In an embodiment, the method comprises detecting, at a redirect agent implemented in a first machine, a packet that is sent from a client application executing on the first machine toward a server application executing on a second machine; and determining, by the redirect agent, whether a first redirect rule matches the packet. In response to determining that the first redirect rule matches the packet, the redirect agent applies the first redirect rule to the packet to translate the packet into a translated packet, and provides the translated packet to a client agent implemented in the first machine to cause the client agent to transmit the translated packet to a server agent implemented in the second machine.

  • Publication number: 20190303186
    Abstract: Certain embodiments described herein are generally directed to handling a hypervisor restart event in a distributed network system. Embodiments include receiving, by a central controller, a session identifier from a first hypervisor. Embodiments further include comparing, by the central controller, the session identifier to a stored session identifier associated with the first hypervisor. Embodiments further include determining, by the central controller based on the session identifier not matching the stored session identifier associated with the first hypervisor, that the first hypervisor has restarted. Embodiments further include updating, by the central controller, the stored session identifier associated with the first hypervisor to match the session identifier. Embodiments further include identifying, by the central controller, a second hypervisor that is associated with the first hypervisor.

  • Publication number: 20190235894
    Abstract: An approach for a hypervisor to throttle CPU utilization based on a CPU utilization throttling request received for a data flow is presented. A method comprises receiving a request for a CPU utilization throttling. The request is parsed to extract a CPU utilization level and a data flow identifier of the data flow. Upon receiving a data packet that belongs to the data flow identified by the data flow identifier, a packet size of the data packet is determined, and a rate limit table is accessed to determine, based on the CPU utilization level and the packet size, a rate limit for the data packet. If it is determined, based at least on the rate limit, that the CPU utilization level for the data flow would be exceeded if the data packet is transmitted toward its destination, then a recommendation is generated to drop the data packet.

  • Publication number: 20190166109
    Abstract: Certain embodiments described herein are generally directed to methods and apparatus for providing a security parameter index (SPI) value for use in establishing a security association between a source tunnel endpoint and a destination tunnel endpoint. In some embodiments, utilization of the SPI bit space is optimized to allow the scaling of key policies within a network. In some embodiment, using an SPI derivation formula, a server in the network is able to generate SPI values whose bit spaces are optimized to allow key policies to scale out.

  • Publication number: 20190132296
    Abstract: A first host receives a packet from a first compute node for a second compute node of a second host. The payload is larger than a maximum transmission unit size. The first packet is encapsulated with an outer header. The first host analyzes a length of at least a portion of the outer header in determining a size of an encrypted segment of the payload. Then, the first host forms a plurality of packets where each packet in the packets includes an encrypted segment of the payload, a respective encryption header, and a respective authentication value. The payload of the first packet is segmented to form a plurality of encrypted segments based on the size. The first host sends the packets to the second host and receives an indication that a packet was not received. A second packet including the encrypted segment is sent to the second compute node.

  • Publication number: 20190102232
    Abstract: An approach for an adaptive, performance-oriented, and compression-assisted encryption scheme implemented on a host computer to adaptively improve utilization of CPU resources is provided. The method comprises queueing a new data packet and determining a size of the new data packet. Based on historical data, a plurality of already encrypted data packets is determined. Based on information stored for the plurality of already encrypted data packets, an average ratio of compression for the plurality of already encrypted data packets is determined. Based on the average ratio of compression, a throughput of compression value and a throughput of encryption value, a prediction whether compressing the new data packet will reduce a CPU load is derived. If it is determined that compressing the new data packet will improve utilization of the CPU resources, then a compressed new data packet is generated by compressing the new data packet.

  • Publication number: 20190065265
    Abstract: Computer system and method for characterizing throughput performance of a datacenter utilize bandwidth information of physical network interfaces in the datacenter and results of benchmark testing on throughput on a single processor core to compute a plurality of throughput constraints that define a throughput capacity region for the datacenter to improve throughput performance of the datacenter.

  • Publication number: 20190018698
    Abstract: A technique for placing virtual computing instances in hosts in a data center to improve capacity and scalability in the network connecting the hosts in the data center. The network is viewed in regard to the physical placement of the servers and resource slots the servers have for supporting virtual computing instances and in regard to the communication traffic between virtual computing instances supported by the servers. A management system collects the resource slots into slot clusters based on their physical location and the virtual computing instances into virtual computing instance clusters based on communication traffic between pairs of virtual computing instances. The management system then maps the virtual computing instance clusters to the slot clusters to determine their physical placement in the network.
