    Abstract: Example methods and systems for failure handling for service chaining with service path monitoring. One example may comprise a first computer system detecting a data packet that is being forwarded along a first service path. The first computer system may configure a liveness check query and send the liveness check query along with the data packet towards a service virtualized computing instance to cause a liveness check response. In response to detecting the liveness check response from the service virtualized computing instance, the first computer system may determine that the service virtualized computing instance is available. Otherwise, report information may be generated and sent to trigger a switch from the first service path to a second service path that excludes the service virtualized computing instance.

    Abstract: Some embodiments provide novel methods for performing services for machines operating in one or more datacenters. For instance, for a group of related guest machines (e.g., a group of tenant machines), some embodiments define two different forwarding planes: (1) a guest forwarding plane and (2) a service forwarding plane. The guest forwarding plane connects to the machines in the group and performs L2 and/or L3 forwarding for these machines. The service forwarding plane (1) connects to the service nodes that perform services on data messages sent to and from these machines, and (2) forwards these data messages to the service nodes. In some embodiments, the guest machines do not connect directly with the service forwarding plane. For instance, in some embodiments, each forwarding plane connects to a machine or service node through a port that receives data messages from, or supplies data messages to, the machine or service node. In such embodiments, the service forwarding plane does not have a port that directly receives data messages from, or supplies data messages to, any guest machine. Instead, in some such embodiments, data associated with a guest machine is routed to a port proxy module executing on the same host computer, and this other module has a service plane port. This port proxy module in some embodiments indirectly can connect more than one guest machine on the same host to the service plane (i.e., can serve as the port proxy module for more than one guest machine on the same host).

    Abstract: The disclosure provides an approach for computing service paths for a service chain identifying a sequence of services. One method includes including information about a plurality of hosts in a heap. Each of the plurality of hosts includes at least one service virtual computing instance (SVCI) configured to provide at least one of the services of the service chain. The information includes, for each of the plurality of hosts, a number of service paths computed for the service chain at the host and one of a number of services provided by unused SVCIs of the host or a number of consecutive services provided by unused SVCIs of the host. The method further includes selecting a host from the heap based on the information. The method further includes generating a first service path for the service chain, the first service path identifying at least one SVCI of the selected host.
