Abstract: Grouping virtualized computing instances in cloud environments can be achieved utilizing groups of network endpoints, such as hardware devices, virtualized computing instances, etc. The network endpoint group (NEG) provides a logical grouping for providers of backend services that may be arranged on the network endpoints, and may be organized based on the backend service to be provided by the computing environments that operate as network endpoints. For example, the NEGs may be implemented for load balancing applications. The network endpoint groups, and the network endpoints included therein, may be managed using a framework of tools, libraries and application programming interfaces.

Abstract: Systems and methods of offloading multicast virtual network packet processing to a network interface card are provided. In an example implementation, a network interface card can route packets in a virtual network. The network interface card can be configured to receive a data packet having a multicast header for transmission to a plurality of destination virtual machines. The network interface card can retrieve a list of next hop destinations for the data packet. The network interface card can replicate the packet for each next hop destination. The network interface card can encapsulate each replicated packet with a unicast header that includes a next hop destination virtual IP address indicating the next hop destination and a source virtual IP address, and transmit the encapsulated packets.

Abstract: Methods, systems, and apparatus include computer programs encoded on a computer-readable storage medium for firewall policies with improved efficiency. A policy can be defined that specifies a set of firewall rules, where the set of firewall rules provides a respective firewall rule for each layer of a plurality of layers within a hierarchical structure of a network, the network including a plurality of elements. Determining, for a first element within the network, a position within a first layer of the hierarchical structure. In response to receiving a data transmission request to or from the first element, applying the set of firewall rules in accordance with the first layer of the hierarchical structure, where applying the set of firewall rules comprises sequentially applying each respective firewall rule at each layer from an upper layer within the network to the first layer within the network.

Abstract: Establishing proxy-less connectivity from logically isolated virtual private clouds (VPC)within a cloud environment without the use of VPN or VPC peering is provided. Establishing a service attachment in one VPC, related to a service which is to be accessed, and a service endpoint in another VPC allows for private communication between the two networks without exposing the service to other VPCs in the cloud environment.

Abstract: A system and method for protocol independent multi-flow table routing includes a first flow table, a second flow table, and a shared hash table accessible by both the first flow table and the second flow table. Upon receipt of a packet, a first secure signature of a first lookup key is generated for the first flow table, and a second secure signature of a second lookup key is generated for the second flow table. The shared hash table stores both the first secure signature in association with a first value corresponding to the first secure signature, and the second secure signature along with a second value corresponding to the second secure signature. The first and second values indicate destination information for the packet.

Abstract: A method and apparatus are provided in which a source and target perform bidirectional forwarding of traffic while a migration guest is being transferred from the source to the target. In some examples, the migration guest is exposed to the impending migration and takes an action in response. A virtual network programming controller informs other devices in the network of the change, such that those devices may communicate directly with the migration guest on the target host. According to some examples, an “other” virtual network device in communication with the controller and the target host facilitates the seamless migration. In such examples, the forwarding may be performed only until the other virtual machine receives an incoming packet from the target host, and then the other virtual machine resumes communication with the migration guest on the target host.

Abstract: The present invention pertains to the allocation of bandwidth on a global large scale network. Systems and methods are provided to base bandwidth allocation on the predicted bandwidth demands of the network users. In allocating bandwidth, each user is assigned a user weight value, and is to be allocated bandwidth in proportion to that value. In addition, the bandwidth allocation is enforced so as to ensure that bandwidth allocation policies are maintained.

Abstract: Systems and methods for achieving high utilization of a network link are provided. A first communication protocol can be selected for transmitting network flows of a first type. A first quality of service can be assigned to network flows of the first type. A second communication protocol can be selected for transmitting network flows of a second type. A second quality of service, lower than the first quality of service, can be assigned to network flows of the second type. A first percentage of available bandwidth can be allocated to the network flows of both the first and second types. The remaining bandwidth, plus a second percentage of available bandwidth, can be allocated to the network flows of the second type, such that the total allocated bandwidth exceeds the available bandwidth of the network link.

Abstract: Systems and methods are provided for allocating network resources across network flow aggregates to apply fairness at different levels of flow aggregation. Utility functions of member flows in each aggregate may be adjusted based on a target aggregate utility function. Processes for allocating network resources may then be performed using the adjusted member utility functions.
