Abstract: Techniques are presented herein for optimizing secure communications in a network. A router in a virtual private network determines whether or not it has successfully registered with a key server that provides cryptographic keys for routers in the virtual private network. The router stores state information that is indicative of whether or not the router has successfully registered with the key server.

Abstract: A first virtual machine is established in a virtual private service chain to provide a first network service to virtual private service chain traffic. A second virtual machine is also established the virtual private service chain to provide a second network service to the virtual private service chain traffic. The virtual private service chain traffic is encrypted for transmission within the virtual private service chain from the first virtual machine to the second virtual machine, wherein the encryption uses a key shared by the first and second virtual machines.
