Latest Patents

The latest patents attributed to Andersson include:

1. **Queue management system having one read and one write per cycle by using free queues** - This invention focuses on a buffer memory, method, and buffer controller designed for queue management, particularly useful in ATM (Asynchronous Transfer Mode) switches. The invention enhances data cell throughput in buffer memory by employing an organized system of 256*(424+8) SRAM cells. This structure facilitates the management of ten queues along with two free-queues that contain idle cells, ultimately aiming for higher efficiency in data handling.

2. **Multicasting method and arrangement** - This patent pertains to a method and arrangement that facilitates multicasting, which is the point-to-multipoint transmission of data packets. The innovative design allows a data packet to be copied and sent to multiple addresses simultaneously. In this system, the input port detects the multicasting packet and forwards it to an appropriate output port. The output port, in turn, copies the data packet, modifies the address, and manages the return of the packet via a direct channel integrated within the link interface. This innovation aims to enhance the overall efficiency of multicasting by effectively distributing the copying process across various output ports of the switch core.
