The edge forwarding element receives data messages for forwarding and performs a service classification operation to select a set of services of a particular type for the data message. The particular type of service is one of multiple types of services that use different transport mechanisms to forward the data to a set of service nodes (e.g., service virtual machines, or service appliances, etc.) that provide the service. The edge forwarding element receives the data message after the selected set of services has been performed and performs a forwarding operation to forward the data message. In some embodiments, the method is also performed by edge forwarding elements that are at the edges of logical network segments within the logical network.

Embodiments described herein are directed to creating a cognitive heterogeneous ad hoc mesh network via generation and utilization of a participant table. Participant object transmit notification signals to inform other participants objects in line-of-sight of their position and movement.

If the receiving mobile participant is responsible for forwarding participant table updates to the sending mobile participant, then the receiving mobile participant includes the received notification signal with the transmission of its next notification signal to propagate the participant table update to a stationary participant. The stationary participant can then transmit participant table updates to other mobile participants. If a stationary participant is not accessible or not functioning, the participants continue to propagate participant table changes when a responsible forwarding participant changes.
