In the embodiment of the present invention:
Protocol stack (Protocol stack), also known as protocol stack are that one of computer network protocol external member is specific
Software realization.An agreement in protocol suite is usually only to design for a purpose, and design can be made more to hold in this way
Easily.Because each protocol module will usually be communicated with upper and lower two other protocol modules, they are usually it is envisioned that at being association
Discuss the layer in stack.The agreement of lowermost level always describes to interact with the physics of hardware.Each advanced level increases more characteristics.
User application is the agreement for handling top layer.
It is wireless that Pipe (Wireless Pipe) --- phytype=" atheros " refers to based on the wireless of wlan_mwds
mesh_Pipe；
Common wireline Pipe (ethernet Pipe) --- phytype=" ethernet " refers to the base in same broadcast domain
In two layers of wired mesh_Pipe；
Ip_tunnel Pipe --- phytype=" ip_tunnel ", for establishing three layers of Mesh net across local area network
Network.Divide both of which by working method difference: actively, non-active；
Ip Pipe --- phytype=" ip " refers to the changing based on three layers of wired mesh_Pipe in same broadcast domain
Become the ability for having extension other types link, multimedium fusion may be implemented under the application of Mesh Pipe, give business by Fig. 6
Unit provides unified network interface, so business unit just has the ability across medium, business unit only needs standard Ethernet interface
Access；Such as: communication unit can be directly accessed the wireless communication system of multimedium fusion by Mac layers.It can also be by
IP_tunnel Pipe accesses the wireless communication system of multimedium fusion by IP, and no matter that is accessed, and merges by multimedium
Wireless communication system after all provide unified standard Ethernet interface.
