Abstract:
1. For a first managed switching element that implements a logical switching element along with a plurality of additional managed switching elements, a method comprising: receiving a packet for processing through the logical switching element at an ingress port of the first managed switching element that connects to a source of the packet; at the first managed switching element, performing a set of ingress context mapping operations to determine a logical context of the received packet; at the first managed switching element, performing a set of logical ingress access control list (ACL) operations to determine whether to further process the packet based on the logical context of the packet; when the logical ingress ACL operations determine to continue processing the packet, performing a set of logical forwarding operations at the first managed switching element to determine a destination logical port of the logical switching element to which to forward the packet; at the first managed switching element, performing a set of logical egress ACL operations to determine whether to further process the packet through the logical switching element based on the destination logical port of the logical switching element; when the logical ACL operations determine to continue processing the packet, performing a set of physical forwarding operations to determine a destination physical port of a second managed switching element of the plurality of managed switching elements that corresponds to the destination logical port of the logical switching element; and forwarding the packet to the destination physical port of the second managed switching element.
