NAME
     ipgpc - IP Generic Packet Classifier

DESCRIPTION
     The IP Generic Packet  Classifier  (ipgpc)  module  provides
     packet  classification  at the Solaris IP layer. ipgpc is an
     implementation  of  the  Multi-Field  (MF)   classifier   as
     described  in  RFC2475:  An  Architecture for Differentiated
     Services.


     The classifier is configured,  at  startup  or  dynamically,
     using  a  set  of "filters." Filters describe selectors that
     are matched against input packets that are processed by  the
     classifier.  Some  selectors  feature  exact  matching  data
     points, while others  utilize  non-exact  or  wildcard  data
     points.


     Each filter is associated with a class describing  the  next
     actions to process a packet. There is a many-to-one (M-to-1)
     mapping relationship between filters and a class.  Addition-
     ally,  each  class  is aware of which filters are associated
     with it. A class is configured with a class name and a  next
     action.


     Unlike traditional classifiers used in edge  routers,  ipgpc
     is  designed for a host or server device. A host-based clas-
     sifier provides access to more resources and data than  edge
     routers. User, project, and interface information are avail-
     able at the host.

  Statistics
     The ipgpc module exports  global  and  per-class  statistics
     (available through kstat:)


     Global statistics:

       module: ipgpc                           instance:
       name:   ipgpc global stats              class: 
               crtime
               snaptime
               nbytes                          
               nclasses                        
               nfilters                        
               npackets                        
               epackets
