Abstract
A packet network includes packet engines that perform packet handling. Cipher engines are provided separately from the packet engines for encryption and/or authentication operations. To preserve relative timing and ordering of data packets, a packet engine performs pre-shaping of data traffic, wherein the packet engine inserts dummy packets into a data flow. The packet engine provides the pre-shaped data traffic to a cipher engine.
