<A NAME="sec:dsedge"></A><BR>9.2.2 Edge and core routers</H2>
The DiffServ edge and core routers are defined in
class <TT>edgeQueue</TT> and class <TT>coreQueue</TT>,
which are derived from class <TT>dsREDQueue</TT>,
see <TT>dsEdge, dsCore.{h,cc}</TT>.
Packet marking is implemented in class <TT>edgeQueue</TT>.
A packet is marked with a code point according to
the policy specified
before it is put into the corresponding physical and virtual queue.
Class <TT>edgeQueue</TT> has a reference to an instance of
class <TT>PolicyClassifier</TT>,
which contains policies for packet marking.
