Abstract
An Ethernet controller, for use within an Ethernet network of other Ethernet controller connected together by a bus, is provided. The Ethernet controller includes a plurality of ports including at least one bus port associated with ports connected to other switching Ethernet controllers, a hash table for storing addresses of ports within the Ethernet network, a hash table address control, a storage buffer including a multiplicity of contiguous buffers in which to temporarily store said packet, an empty list including a multiplicity of single bit buffers, a packet storage manager, a packet transfer manager and a write-only bus communication unit. The hash table address control hashes the address of a packet to initial hash table location values, changes the hash table location values by a fixed jump amount if the address values stored in the initial hash table location do not match the received address, and provides at least an output port number of the port associated with the received address. The packet storage manager associates the state of the bit of a single bit buffer with the empty or full state of an associated contiguous buffer and generates the address of a contiguous buffer. The packet transfer manager directs the temporarily stored packet to the port determined by said hash table control unit. The write-only bus communication unit is activated by the packet transfer manager, for transferring the packet out of the bus port by utilizing the bus for write only operations.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
