An extension to Transport Layer Security (TLS) 1.3 to enable session migration. This mechanism is designed for modern network architectures, particularly for multi-homed servers that possess multiple network interfaces and IP addresses. Comparing to the existing solutions such as maintaining the customer- based connection status table in network devices, HTTP redirection and DNS redirection, this solution can avoid the waste of resources caused by saving a large amount of customer status data in the network devices, and realize the optimized scheduling of resources based on network conditions and computing resources in the computing- aware traffic steering scenario, so as to realize the reasonable operation of network resources, cloud resources and computing resources.}, }
