Abstract
In a multi-core system, multiple packet engines across corresponding cores may be working concurrently processing data packets from data flows of SSL VPN sessions. For example, a first core may establish a SSL VPN session with a client. Any one of the other cores, such as a second core, may received packets related to the session owned by the first core. Embodiments of the systems and method described below provide management of IIP addresses for the multi-core/multi-packet engine approach to providing SSL VPN service. In some embodiments, the approach to managing IIP addresses is to have one packet engine on a core act as a master or controller of the IIPs for the remaining packet engines and cores. The packet engines/cores use a protocol for communications regarding IIP management.
