Abstract
Systems and methods described herein use a variable 2MSL timer (also referred to herein as a “port reuse timer”) for a core network/gateway. A network device in a core network detects closing of a session that uses a port designated for Network Address Translation (NAT), monitors an overall NAT port utilization level, and manages release timing for the port based on the overall port utilization level.
