Abstract: A method and system of transmit load balancing across multiple physical ports. At least some of the illustrative embodiments are methods comprising teaming a first and second communication ports to create a teamed communication port, creating a plurality of virtual ports which abstract the first and second communication ports (and wherein a number of virtual ports utilizing each communication port is based on parameters associated with the communication ports), selecting one of the plurality of virtual ports out which to send a message packet thus designating a select virtual port (the selecting implements transmit load balancing across plurality of virtual ports) and sending the message packets out the first or second communication port utilized by the selected virtual port.
