Abstract: In an embodiment, a method for a VRF and multi-service insertion on edge gateways is described. In an embodiment, the method comprises obtaining a rule configuration. Based on, at least in part, the rule configuration, a rule table is created. The rule table comprises rule data records, wherein a rule data record comprises packet attributes and a redirection identifier. A policy configuration comprising policy records is obtained. Each policy record comprises a redirection identifier, a next_hop, and an address pair for interfaces. A mapping between VRF identifiers and address pairs is generated. Based on, at least in part, the mapping and the policy configuration, a policy table is generated. The policy table comprises table records, wherein a table record comprises a redirection identifier, a next_hop, and an address pair. The rule and policy tables are used to redirect a packet from an edge gateway to a service virtual machine.

Abstract: Methods, computer-readable storage medium, and systems described herein facilitate registering and consuming network services on a virtual network. A virtual machine management server (VMMS) is configured to receive a service definition associated with a network service. The VMMS creates one or more service profiles based on the service definition. The VMMS configures a plurality of hosts based on the one or more service profiles such that the network service is usable, via a virtual network, by one or more virtual machines within the plurality of hosts.

Abstract: An example method of packet processing in a host cluster of a virtualized computing system includes: receiving traffic at packet processing software of a hypervisor executing on a host of the host cluster; processing the traffic using a network service of the packet processing software in the hypervisor; redirecting the traffic to a service virtual machine (VM) in the host cluster through a virtual network interface card (vNIC) of the service VM; sending metadata from the network service of the packet processing software to the service VM; processing the traffic and the metadata through at least one network service executing in the service VM; returning the traffic from the service VM to the packet processing software of the hypervisor; and forwarding, by the packet processing software, the traffic to a destination.

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.

Abstract: Example methods are provided for packet handling during service virtualized computing instance migration in a software-defined networking (SDN) environment. The method may comprise configuring first reachability information to associate a first service virtualized computing instance with an active role, and second reachability information to associate a second service virtualized computing instance with a standby role. In response to determination that a switchover is required to facilitate a migration of the first service virtualized computing instance, the first reachability information may be updated to associate the first service virtualized computing instance with the standby role, and the second reachability information to associate the second service virtualized computing instance with the active role. The method may also comprise: in response to detecting a completion of the migration, updating the first reachability information to associate the first service virtualized computing instance with a target host instead of a source host.
