Methods, non-transitory computer readable media, session director apparatuses, and network traffic management systems that facilitate packet data network (PDN) service slicing with microsegmentation in an evolved packet core are disclosed. With this technology, a create session request (CSR) general packet radio service (GPRS) tunneling protocol (GTP) control (GTP-c) message is intercepted. A lookup key is then determined based on content of the intercepted CSR GTP-c message. A PDN gateway (PGW) identifier for a PGW is obtained using a slice name obtained using the lookup key. The intercepted CSR GTP-c message is modified to include the obtained PGW identifier. Subsequently, the modified CSR GTP-c message is steered based on the obtained PGW identifier, such as directly to the PGW or to a serving gateway (SGW) module associated with the PGW.

Embodiments are directed towards overprovisioning IP addresses among a plurality of traffic management devices (TMDs). A plurality of IP addresses may be distributed among a plurality of available TMDs. A corresponding mirror TMD may be determined for each IP address. The corresponding mirror TMD for an IP address may be different than the available TMD currently associated with the IP address. In various embodiments, connections associated with each IP address may be mirrored at their corresponding mirror TMDs. The available TMDs may be employed to perform traffic management tasks on received packets based on at least a destination IP address of the received packets and the IP addresses associated with the available TMDs. If a TMD becomes unavailable, the IP addresses associated with the unavailable TMD may be redistributed to at least one remaining available TMD.
