Abstract:
The disclosure provides an approach for pre-filtering traffic in a logical network. One method includes receiving, by a hypervisor, a packet from a virtual computing instance (VCI) and determining a service path for the packet based on a service table. The method further includes setting, by the hypervisor, a pre-filter component as a next hop for the packet based on the service path. The method further includes receiving, by the pre-filter component, the packet. The method further includes making a determination, by the pre-filter component, of whether the packet requires processing by the security component. The method further includes performing, by the pre-filter component, based on the determination, one of: forwarding the packet to its destination and bypassing the security component; or forwarding the packet to the security component.
