Common Classification (
CC
herein after) is commonly used within the network
devices in order to selectively categorize packet traffic and deal with it differently.
CC find its application in various areas such as:
•
Filtering for allowing selective route re-distribution from one routing protocol to
another
•
Firewalling
•
Tunnelling
•
Categorizing and prioritizing traffic for meeting the QoS requirements.
The evolution of network devices has thrown up some interesting facts. As new
features were developed, the classification became more complex and varied.
This complexity grew from the fact that people wanted to match traffic on
increasing number of packet fields. Enhancement in speeds of the interface and
switching has increased ascent on classification performance. Last but not the
least, a generic classification model was required in order to match traffic classes
which could be used for variety of services like QoS, VPN, Firewall, IDS, etc.
The OA-700 incorporates multiple services like routing, switching, firewall, VPN,
and QoS. As part of our unified architecture, we have evolved a common classifier
design which decouples classification and action. Thus, the same classifier can
be used across all applications.
