    Abstract: Techniques are presented for optimizing secure communications in a network. As disclosed herein, a key server is configured to provision a plurality of routers that are part of a virtual private network. The key server selects a counter value that is part of a security association and calculates a key value. The key server sends the key value, together with the security association, to the plurality of routers that are part of the virtual private network to enable them to exchange encrypted packets with each other in the virtual private network using the key value and the security association. The key server then increments the counter value to a value within a range of counter values capable of being predicted by the plurality of routers that received the key value.

    Abstract: Techniques are presented for optimizing secure communications in a network. A first router receives from a second router an encrypted packet with an unknown security association. The first router examines the packet to determine whether the counter value is in a range of predicted counter values. Additionally, a key server is configured to provision routers that are part of a virtual private network. The key server selects a counter value that is part of a security association and calculates a key value. The key server sends the key value together with the security association to enable routers to exchange encrypted packets with each other in the virtual private network using the key value and the security association. The key server increments the counter value to a value within a range of counter values capable of being predicted by the routers.

    Abstract: Techniques are described herein for optimizing communications in a network. At a router in a virtual private network, a packet is received from a device in a subnetwork protected by the router. The router examines the packet to determine a source address that identifies the device and a destination address that identifies a destination network device for the packet. The router also analyzes the packet to determine a size of the packet and determines whether or not the size of the packet is larger than a maximum transmission unit size. If the size of the packet is larger than the maximum transmission unit size, the router encapsulates the packet with a header that includes the destination address and a new source address that identifies the router.
