• Definitive Packet Classifier

This is an attempt to fully implement rfc 4594, along with some proposed extensions, at the edge router on the home gateway. The results should be suitable also for hotels, convention centers and small businesses.

It could be further extended by supplying tables to end machines, to classify their behavior at the switch, rather than router level.

It is being tested within the auspices of the 'uberwrt' series of projects.

• Requirements Be both ipv6 and ipv4 enabled. Handle packet encapsulation (VPN) traffic correctly
• Components Debloating Techniques ** Minimize multicast Short queue lengths Use web proxies by default (wpad and dhcp supplied) ECN Enabled *** Optimizations for

Classifier ** Shall include comprehensive port to dscp database. Shall also include anti-worm filtering ** Bandwidth Shaper(s) and policer(s) The bandwidth shapers should be as simple as possible, but no simpler.

Example logic would include the number and type of machines in a household, the kinds of traffic the user expects, etc.

It would be good to allow for bandwidth sharing. Should penalize

** DSCP statistics Complete DSCP statistics will be kept.

Wired and Wireless awareness ** 802.11e converter Wherever possible, packets will be transformed into their proper 802.11e classes. 802.11d converter Wherever possible, packets will be transformed into their proper 802.11d classes.

• Futures Simple lookup tables for DSCP <-> Port mappings Simple lookup tables for threats ** Support for multiple switch types and vlan prioritizations

• Tasks Ahead TODO Write Good classifier Analyze existing realistic traffic Measure existing shapers Implement ECN in existing shapers **
