Abstract: In some embodiments, the present disclosure provides for accelerating cross-sited resources in an accelerated document. In some embodiments, a set of rules is created to determine which cross-site resources will be accelerated. Using the rules, a first cross-site resource is selected for acceleration. The cross-site resource is cached on a CDN edge server. A link for a first cross-site resource is wrapped so that a client will be directed to retrieve the cross-site resource from the CDN edge server. The client receives the cross-site resource directly from the CDN edge server.

Abstract: Operating a message queue cluster having multiple nodes. A messaging request from a client is obtained by one or more processors, the messaging request to be routed to one of multiple nodes in a cluster. The one or more processors parse the messaging request to determine whether the messaging request should be routed to an other node. A messaging request is obtained from a client by one or more processors, the messaging request to be routed to one of multiple nodes in a cluster. The messaging request is parsed by one or more processors to determine whether the messaging request should be routed to an other of the multiple nodes in the cluster. The messaging request is routed by one or more processors in response to a determination that the messaging request should be routed to the other one of the multiple nodes in the cluster.

Abstract: A method for load balancing network traffic. First network address translation rules are executed with respect to a first data packet of the network traffic to translate initial address space data thereof, with respect to an initial destination network address and port identifier. An entry is generated with respect to the first data packet that includes data related to the translated destination network address and port identifier, and an initial source network address and port identifier. A second data packet is received from a client. The generated entry is identified and implemented in executing second network address translation rules with respect to the second data packet, to translate address space data thereof with respect to an initial destination network address and port identifier, for routing thereof to the host, and upon servicing, for routing thereof directly to the client.

Abstract: An approach includes providing support multi-tenancy support on a DHCP protocol. The approach includes receiving a dynamic host configuration protocol (DHCP) packet, inserting a tenant-specific option information within the DHCP packet, and transmitting the DHCP packet with the tenant-specific option information.

Abstract: An expandable package filler or ornament includes a stack of sheets, such as tissue paper, foil, etc. The stack is bound together, such as by a fastener. A generally spiral cut extends from a peripheral edge of the stack toward the center of the each sheet. The cut forms each sheet into a generally spiral strip ending in a peninsula portion. Grasping the peninsula portion, lifting and shaking the stack causes the strips to fall and entangle with each other. The resulting structure is decorative and may be used to stuff a gift box, bag or basket.

Abstract: Embodiments disclose systems, methods, and computer program products to perform an operation for generating entropy values for packets in an overlay network. The operation generally includes generating a first entropy value for each packet in a first group of packets received in a sequence of packets from a host, and detecting an idle amount of time between the the first group of packets in the sequence of packets and a second group of packets in the sequence of packets received from the host. The operation also includes upon determining that the idle amount of time is greater than a first threshold, generating a second entropy value for each packet in the second group of packets. The operation further includes inserting the second entropy value in an outer header of each packet in the second group of packets, and transmitting the second group of packets to the underlay network.

Abstract: A load-balancer instance is instantiated in a network virtualization edge (NVE) in a software defined network (SDN). A forwarding table in the NVE is modified to indicate that a next hop for a packet having a destination address of the load-balancer instance is to be resolved by the load-balancer instance. From a portion of the packet, and using the load-balancer instance, a value usable to select a singular next hop to a first real server in a pool of real servers managed by the load-balancer instance is determined. The packet is forwarded, using the modified forwarding table, the packet through an underlay of the SDN such that the packet tunnels from the NVE to a first NVE, the second NVE hosting the first real server.

Abstract: A method includes obtaining, by one or more processor, data from a virtual network of a tenant and an identifier of the tenant, where the virtual network of the tenant is one of at least two virtual networks in a shared computing environment where the at least two virtual networks overlay a physical network. Based on obtaining the identifier of the tenant, the method includes setting, by one or more processor, the identifier in metadata of the data and based on the identifier in the metadata, identifying, by the one or more processor, a network connection associated with the tenant. The method also includes identifying, by the one or more processor, a policy of the network connection and processing the data with the policy to create processed data and transmitting, by the one or more processor, the processed data through the network connection.

Abstract: In one embodiment, a system includes a processing circuit and logic integrated with and/or executable by the processing circuit that causes the processing circuit to receive a congestion notification message from a first virtual switch of a first server indicating that a first virtual machine (VM) hosted by the first server is overloaded. The logic also causes the processing circuit to advertise a congestion status of the first VM in a congestion status message to one or more virtual switches in a network in response to receiving the congestion notification message. Moreover, the logic causes the processing circuit to cause all virtual switches in the network except for the first virtual switch to stop sending traffic destined for the first VM while the first VM is overloaded without restricting sending traffic that is destined for other VMs hosted by the first server.

In another embodiment, a method includes receiving, using a first virtual switch of a first server, a congestion status message from a controller indicating that a second VM hosted by a second server is overloaded, and stopping traffic that is destined for the second VM from being sent in response to receiving the congestion status message from the controller without restricting sending traffic that is destined for other VMs hosted by the second server.
