Abstract
Systems are methods are provided for implementing load balancing of IPsec security associations (SAs) SAs between different heterogeneous cores, for example in a multiple controller systems. The balancing of IPsec SAs are performed using software implementations of IPsec offloading and/or hardware implementations of IPsec offloading. By balancing the processing functions related to orchestration of IPsec SAs between hardware (e.g., IPsec hardware accelerator) and software (e.g., IPsec software accelerator), the methods realize increased optimization, improved user experience, and enhanced product performance in networks using IPsec. For example, an IPsec session is initiated, and it is determined whether a resource limitation for a hardware-based IPsec accelerator has been reached. If the limitation for the hardware-based IPsec accelerator has been reached, processing for the IPsec SA for the initiated IPsec session is offloaded to a software-based IPsec accelerator.
