    摘要: A packet classifier and a method for routing a data packet are provided. The packet classifier includes a content addressable memory, a translation table and a parameter memory. The method includes looking up a content addressable memory for a base address into a parameter memory using a header of the data packet. The base address is related to the routes under ECMP for forwarding the data packet. From among these addresses, using multiple headers of the data packet, an adjustment to the base address is computed. The adjustment specifies an actual address to the parameter memory corresponding to a selected route for forwarding the data packet. The parameter memory is then accessed using the actual address to obtain parameter values relevant to the selected route. The data packet is then forwarded according to the parameter values thus obtained.

    摘要: Techniques that offer enhanced diversity in the selection of paths (e.g., ECMP paths) and/or ports from ports associated with trunks for forwarding network data traffic. In one embodiment, a network device uses a rotate function to generate a rotated index (path index) that is used to select a path (e.g., an ECMP) path from multiple paths (e.g., multiple ECMP paths) for forwarding a packet. A network device may also generate a rotated index (trunk index) that is used to select an output port from multiple output ports associated with a trunk for forwarding the packet.

    摘要: The provisioning of a host computing system by a controller located over a wide area network. The host computing system has power-on code that automatically executes upon powering up, and causes the host to notify the controller of the host address. In a first level of bootstrapping, the controller instructs the host to download a maintenance operating system. The host responds by downloading and installing a maintenance operating system, enabling further bootstrapping. The persistent memory may further have security data, such as a public key, that allows the host computing system to securely identify the source of the download instructions (and subsequent instructions) as originating from the controller. A second level of bootstrapping may accomplish the configuring of the host with a hypervisor and a host agent. A third level of bootstrapping may accomplish the provisioning of virtual machines on the host.

    摘要: Cloud computing platforms having computer-readable media that perform methods for direct addressability and direct server return are provided. The cloud computing platform includes a load balancer and several servers. The servers are configured with public addresses, private addresses, and an address of the load balancer. The loopback interface of the servers is configured with the address of the load balancer. This allows a server to bypass the load balancer when replying to communication messages. Additionally, the public and private addresses of the servers enable direct addressability in the cloud computing platform. Accordingly, an application executing in the cloud computing platform may connect two or more clients on the same server.

    摘要: The movement of a Virtual IP (VIP) address from cluster node to cluster node is coordinated via a load balancer. All or a subset of the nodes in a load balancer cluster may be configured as possible hosts for the VIP. The load balancer directs VIP traffic to the Dedicated IP (DIP) address for the cluster node that responds affirmatively to periodic health probe messages. In this way, a VIP failover is executed when a first node stops responding to probe messages, and a second node starts to respond to the periodic health probe messages. In response to an affirmative probe response from a new node, the load balancer immediately directs the VIP traffic to the new node's DIP. The probe messages may be configured to identify which nodes are currently responding affirmatively to probes to assist the nodes in determining when to execute a failover.

    摘要: Discovery of intermediate network devices is performed using a technique that piggybacks upon the existing standard TCP (Transport Control Protocol) “SACK” (Selective Acknowledgment) option in a SYN/ACK packet so that discovery information may be shared between pair-wise-deployed peer intermediate devices when a TCP/IP connection (Transport Control Protocol/Internet Protocol) is first established between network endpoints using a conventional three-way handshake. Use of the SACK option is combined with another technique which comprises modifying the original 16-bit value of the TCP receive window size to a special arbitrary value to mark a SYN packet as being generated by a first peer device. The marked SYN when received by the second peer device triggers that device's discovery information to be piggybacked in the SACK option of the SYN/ACK packet. The first device then piggybacks its discovery information in the SACK option of the ACK packet which completes the three-way handshake.
