On, the Ethernet exchange does not partially replace the Ethernet controller, and the Ethernet is cheaper at a lower cost. Hugh, in the receiving direction, externally received P number P Ethernet controller, Ethernet controller will be P to the processor, processor P VA special, and in advance, stripping P VA in the direction, the processor will P adds VA, the Ethernet controller sends the VA to the P, PP, and the P is external to the phase.

The following is a breakdown of the details. The Ethernet system includes a connector supporting the external component interconnection (C, e phe a Co po ee co ec ), the processor C is connected to the Ethernet controller, and the processor does not include a built-in fast external Ethernet controller. In the case of Ethernet exchange, the Ethernet exchange has multiple ethers, some of which are outside the fixed force, and generally no less than 4/external, as explained below with 4 external connections.

Steps, ether exchange.

First, the Ethernet exchanges 1 P and 4 externally, respectively, 4 externally assigned 4 different AC addresses, 4 external 4 AC addresses, and external P to the destination AC non-AC address will prohibit this exchange.

At the same time, the external 4 V A of the Ethernet exchange, 4 externally belong to 4 different V A , CP is the same as 4 V A , and V A has a unique V A (TAG). The external and P are the same as the V A. The externally exchanged P can only be specific to P and not to other externals.

V A , in the Ethernet exchange internal external with the same number of paths, only the external and P can be special, and the ether exchanges the external.

The externally exchanged P can only be specific to P and not to other externals.
