摘要： An approach is provided in which an information handling system receives, at a network virtualization edge (NVE), a set of Diffserv parameters comprising at least one classifier parameter, at least one meter parameter, at least one marker parameter, and at least one shaper/dropper parameter. The NVE performs a deep inspection on a plurality of data packets to classify the plurality of data packets at one or more classification levels. In turn, the NVE passes the set of Diffserv parameters and the one or more classification levels to underlay switch hardware.

摘要： A method and system for virtual networking is provided. The method includes receiving logical service chain data describing a source virtual network ID (VNID) for a source virtual network, a destination VNID for a destination virtual network, and a group of intermediate waypoints. The logical service chain data defines a logical service chain. A set of networked virtual environments (NVE) is selected to support the group of intermediate waypoints and the logical service chain is deployed and mapped to a physical service chain implemented on the set of NVEs. The logical service chain data is transmitted to a network virtual authority (NVA) and a packet forwarding mechanism is introduced when a packet is received from an overlay port or an underlay port. An associated IP address is requested and the first packet is analyzed.

摘要： 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.

摘要： A method, computer system, and computer program product 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.

摘要： An approach is provided in which an information handling system matches packet properties of an egress data packet to a classification rule corresponding to differentiated services (DiffServ) parameters. The information handling system encapsulates the egress data packet with a network virtualization overlay header that includes a DiffServ classification identifier corresponding to the DiffServ classification rule. In turn, the information handling system sends the encapsulated egress data packet to a downstream network component.
