Abstract: Described herein are systems, methods, and software to enhance network traffic management. In one implementation, a first host identifies a packet to be transferred from a first virtual machine on the first host to a second virtual machine on a second host. In response to identifying the packet, the first host identifies a source logical port for the first virtual machine, and transferring a communication to the second host, wherein the communication encapsulates the data packet and the source logical port. Once the packet is received by the second host, the second host may use the source logical port to determine a forwarding action for the packet.

Abstract: In some embodiments, a method determines when a packet is fragmented into multiple fragmented packets in a flow between a first workload and a second workload. The method switches from generating an outer source port in the outer header using layer 4 information from the inner header to using layer 3 information from the inner header. A fragmented packet is encapsulated with the outer header that includes an outer source port value that is generated using the layer 3 information. The method initiates a process to determine when to switch back to using layer 4 information from the inner header to generate the outer source port. When it is determined to switch back to using layer 4 information, the method switches back to using layer 4 information from the inner header to generate the source port in the outer header of a packet from the first workload.
