 ## Frame Types
-Chapar support **UniCast** and **BroadCast** frame and not support **MultiCast**. We strongly suggest use broadcast frames just in network discoverable mechanism like find GP network coordinators. Also to broadcast emergency messages service.

+## Switching
 
-### Blocking
-transmitting will block sender until frame transmitted successfully. Sender can be sure frame transmitted.
+### Adaptor
+When two peer connect by two different port number, one of them must be as switching adaptor. That means **usually higher hop** must add virtual switch hop to switching road. It will add one more hop port number in each chapar frame. Suggest to be addable port protocol like [SFP](https://en.wikipedia.org/wiki/Small_form-factor_pluggable_transceiver).
 
-### Non blocking
-transmitting will not block caller to be non blocking and queue frames for congestion situations.

 A situation might be occur that a port available when a frame queued but when the time to send is come, the port broken and sender don't know about this.

 ## Hardwares
-Chapar functions can add by switching fabric unit (SFU) in any devices by any interfaces like PCIe, .... It can have 1 to 256 wired port or 2^16(65536) wireless port. Each Chapar wireless switch device handles two hops of the frame instead of regular one hop in each switching hop. It means each wireless hot-spot can serve  2^16(65536) devices.

-The line processing unit (LPU) provides physical interfaces connecting the SFU to external networks. The LPU processes and forwards service data. In addition, the LPU maintains and manages link protocols and forwarding information base (FIB) tables and frames congestions.

 Like other wireless technology, We must provide some dedicate channel:
 - Broadcast control channel (BCCH) to manage broadcasting for all user equipment
 - Paging control channel (PCCH) to manage paging messages --- why not page device by DTCH?????
