- the addressing module obtains the freest target physical address based on the target logical or service address.
- the system monitoring module is responsible for monitoring the status of each client and writing the status to the addressing table.
- the information of bus A and B gets their own receiving and sending queues after registering the system; 1) The information of bus A sends a request to the sending queue of A001S (B, Data A, A001R); where B represents the logical destination address, and Datal represents the request Content, A represents the source logical address, and A001R represents the source physical i;
- the core switching module detects that there is a data request in A001S and receives it;
- the core switching module obtains the physical address B of BQQ1R according to the addressing table, and sends the request to B001R;
- the bus B obtains a data request from B001R and processes it;
- Bus B sends response data (A, A001R, Data2, B) to B001S;
- the core switching module detects that there is a data request in BQ01S and receives it;
- the core switching module detects that the bus A has a physical address, and sends data to A001R without addressing;
- Bus A gets a response from A001R.
- Correction ⁇ (Rule 91)
- the key to the solution here is the ability to maintain the addressing table. For example, for the same bus B, multiple instances are allowed, that is, bus B has multiple physical addresses in the addressing table, in which the running status of each address is recorded, and the core switching module can dynamically determine according to the running status when addressing Select the physical address of the least busy instance. This scheme has a dynamic equalization effect on the load of the system.
- switching modules can be added to form a switching cluster. Since the performance of each switching module is stable, within the range allowed by the hardware and the network, the switching capacity of the entire information switch and the number of switching modules The number is nearly linearly expanded.
