摘要： Detecting resource errors in a heterogeneous computing environment is provided. A plurality of individual resource dependency graphs corresponding to a plurality of computing systems that comprise the heterogeneous computing environment is consolidated to form a consolidated resource dependency graph. An analysis of respective nodes representing respective resources of the heterogeneous computing environment in the consolidated resource dependency graph is performed to identify a resource error caused by a new resource being added to a computing system of the plurality of computing systems based on defined rule sets. It is determined whether the new resource causes an error to sibling resources at a same level under a parent resource in the consolidated resource dependency graph based on the analysis. In response to determining that the new resource does not cause an error to the sibling resources, the new resource is deployed in the computing system of the heterogeneous computing environment.

摘要： Embodiments of the invention provide a method for load balancing a networking system comprising multiple computing nodes. The method comprises maintaining one or more data sets on at least one computing node. The method further comprises receiving, from each computing node, a load information unit for the computing node, wherein the load information unit relates to resource usage on the computing node. For each computing node, the method determines whether the load information for the computing node exceeds a corresponding load threshold for the computing node. A data set on at least one computing node is transferred to another computing node when the load information for the at least one computing node exceeds a corresponding load threshold for the at least one computing node.

摘要： In a distributed network environment, a first virtual machine sends a first virtual machine control information to a first network system. The first network system sends a first control information to a first network control system in response to receiving the first virtual machine control information. The first network control system sends a portion of the first control information to a number of network systems. The first network control system sends a second control information to the first network system. The first virtual machine sends a first packet to the first network system which generates a unicast packet using a portion of the first packet and a portion of the second control information. A second network system receives and processes the unicast packet. The second network system sends a copy of the processed unicast packet to a second virtual machine associated with a second tenant.

摘要： In one embodiment, an apparatus includes a processor and logic configured to designate one of a plurality of endpoint virtual network identifiers (EPVNIDs) for each endpoint device in a network, wherein each EPVNID is configured to be shared by one or more endpoint devices, designate a common waypoint virtual network identifier (WPVNID) for all transparent waypoint devices in the network which perform a same function, designate a unique WPVNID for each routed waypoint device in the network, designate a common virtual network identifier (VNID) for all virtual switches in a single virtual network, wherein a different VNID is designated for each virtual network, and create a service chain table comprising each VNID, WPVNID, and EPVNID designated in the network individually correlated with at least a pair of VNIDs: a source VNID and a destination VNID, based on one or more policies affecting application of services to packets in the network.

摘要： Embodiments of the present invention provide methods, computer program products, and systems for fulfilling a service chain request. Embodiments of the present invention can be used to collect network data of a plurality of instances of services and connections between the plurality of instances of services and redefine service chains to direct flow to an alternative instance of a service responsive to determining that an instance of a service in a service chain has become inaccessible. Embodiments of the present invention can be used to fulfill a service chain request and avoid one or more instances of services (and/or connections there between) that could cause a delay between transmitting data packets through the service chain.

摘要： Embodiments of the invention provide a method for data replication in a networking system comprising multiple computing nodes. The method comprises maintaining a data set on at least two computing nodes of the system. The method further comprises receiving a data update request for the data set, wherein the data update request includes a data update for the data set. The data set on the at least two computing nodes is updated based on the data update request received.

摘要： According to one embodiment, a method for asymmetrical link aggregation includes detecting a link change corresponding to a previously selected port of a first set of ports used to forward frames to one of a plurality of aggregation switches connected via the first set of ports to an access switch. The method also includes re-selecting, using the access switch, a port of the first set of ports according to a distribution algorithm that ensures that all frames with a given source address are forwarded using a single port and causes frames with different source addresses to be distributed uniformly among the first set of ports in response to detecting the link change. Also, the method includes generating and sending a fake reverse address resolution protocol (RARP) frame including the given source address of the frame from the re-selected port in response to detecting the link change.
