Hi Frank,

1. It is already referenced in WiMAX NWG for the IPoETH CS service in
Rel 1.0.
   For IPoETH CS a bridge is deployed inside the ASN-GW to provide
Ethernet behavior 
   between FA and the MSs. You will find the description in chapter 6.3
of Stage 3.
   Only the public access scenario is supported in WiMAX NWG to ensure
that all packets
   are passing through the CSN (no direct MS to MS communication
allowed).
   Please contact me if you have any question on the text in the NWG
specification.

   The I-D will find further usage in the upcoming NWG specification for
support 
   of Ethernet services over Mobile WiMAX. Depending on whether Mobile
WiMAX provides 
   a E-LAN or a E-LINE service, the Net-Bridge for the particular VLAN
is located
   in the CSN or outside of the Mobile WiMAX network, respectively.

2. There is no new network entity introduced. The specification
describes functional
   enhancements to the layer 2 switch on the network side (Net-Bridge)
between BS and AR.
   Some of the functional enhancements are well known and may be
commercially available.

Bye
Max

Hi folks

After reading the draft, somethings are not clear to me.

1. can it be applied to WiMAX NWG? If possible, could you give me some
explanation?
   Publice access scenario and enterprise scenario are  illustrated  .
    I wander if  they are deployable.
2. Net-Bridge are separated  from BS and AR. 
   I wander if there is any switch is in line with the requirement with
the Net-Bridge.
   Generally, there is ethernet aggratation network which consists of
layer 2 switch
   between BS and AR.   Now, a new network entity is introduced. 

BR
Frank
