According to one aspect, a method includes coupling first and second security units in series between first and second networks. The first security unit obtains packets from the first network, and the second security unit obtains the packets from the first security unit. The first security unit includes first logic arranged to provide security. The second security unit includes second logic arranged to provide security. The method also includes configuring the second security unit in a bypass mode such that the second logic does not provide security, and obtaining a first packet from the first network via the first security unit. The first packet is identified as secure by the first logic. Finally, the method includes providing the first packet from the second security unit to the second network by passing the first packet through the second unit without using the second logic to provide security.

A method for regulating network traffic may be provided. The method may comprise: measuring usage of a CPU; determining if the CPU usage is greater than an overload threshold value; halting the increase of a data traffic shaping rate associated with traffic regulated by the CPU if the CPU usage is greater than the overload threshold value; determining if the CPU usage is greater than an overflow threshold value; and decreasing the data traffic shaping rate associated with traffic regulated by the CPU if the CPU usage is greater than the overflow threshold value for improving session setup speed.
