摘要： Devices and methods are provided for enabling high-speed data communication at relatively low cost. Some methods allow devices to communicate by selecting a data transfer rate from among multiple data transfer rates. Some such methods allow devices to communicate according to the highest data transfer rate among multiple data transfer rates at which communications can be made without exceeding a predetermined error rate. Communications may be enabled between a first device operating at a relatively higher data transfer rate and a second device operating at a relatively lower data transfer rate. Pause frames or the like may be used to rate limit data received from the first device and maintain an average data transfer rate for communications with the second device at the lower data transfer rate.

摘要： Provided are methods, apparatuses and systems for balancing the load of data transmissions through a port aggregation. The methods and apparatuses of the present invention allocate port assignments based on load, that is, the amount of data being forwarded through each port in the group. The load balancing of the present invention is preferably dynamic, that is, packets from a given stream may be forwarded on different ports depending upon each port's current utilization. When a new port is selected to transmit a particular packet stream, it is done so that the packets cannot be forwarded out of order. This is preferably accomplished by ensuring passage of a period of time sufficient to allow all packets of a given stream to be forwarded by a port before a different port is allocated to transmit packets of the same stream. The invention may be used in a variety of different network environments and speeds, including 10Base-T, 100Base-T, and Gigabit Ethernet, and other network environments.

摘要： Methods and apparatus for enabling communication between a source network device and one or more destination network devices are disclosed. The source network device and the one or more destination network devices are connected via an associated interconnect to a switch having a memory associated therewith. One or more messages are composed at the source network device, where the messages include data and control information associated with the data. The messages are then sent to the switch to enable the data and at least a portion of the control information to be stored in the memory associated with the switch, where the data is stored for retrieval by the one or more destination network devices.

摘要： Provided is a 10Base-T MAC to PHY interface requiring only two wires (pins) per port, with two additional global wires: a clock wire (pin), and a synchronization wire (pin). This reduction in the number of pins associated with each port is achieved by time-division multiplexing wherein each time-division multiplexed wire combines a plurality of definitions from the conventional seven-wire interface. As a result, each port has its own pair of associated time-division multiplexed wires (pins) and the addition of each port simply requires two additional wires. According to a preferred embodiment of the present invention, information normally transferred on nine wires in a conventional seven-wire interface at 10 MHz is time-division multiplexed onto two wires (corresponding to two pins) that transfer data at 40 MHz, four times the speed of conventional interfaces. Importantly, this multiplexing is done on a port by port basis. Therefore, the number of pins required for a MAC to transceiver interface is two times the number of ports plus two instead of nine times the number of ports, and the addition of each additional port requires only two more wires (pins).
摘要翻译：提供了一个10Base-T MAC到PHY接口，每个端口只需要两根电线（引脚），另外两根全球线：时钟线（引脚）和同步线（引脚）。通过时分复用实现与每个端口相关联的引脚数目的减少，其中每个时分复用引线组合来自常规七线接口的多个定义。因此，每个端口都有自己的一对相关联的时分复用电线（引脚），并且每个端口的添加只需要两根额外的电线。根据本发明的优选实施例，在10MHz的常规七线接口中通常在九条线路上传输的信息被时分复用到以40MHz传输数据的两条线（对应于两个引脚）四倍常规接口的速度。重要的是，这种复用是以端口为基础完成的。因此，MAC到收发器接口所需的引脚数量是端口数量的两倍，而不是端口数量的九倍，而每个附加端口的添加只需要两个电线（引脚）。

摘要： Methods and apparatus for enabling communication between a source network device and one or more destination network devices are disclosed. A system enabling communication between a source network device and one or more destination network devices includes a switch and a ring interconnect. The switch is adapted for connecting to the source network device and the one or more destination network devices. More particularly, the switch is capable of storing data provided by the source network device and retrieving the data for the one or more destination network devices. The ring interconnect is adapted for connecting the source network device and the one or more destination network devices to one another. In addition, the ring interconnect is capable of passing one or more free slot symbols along the ring interconnect. Thus, the ring interconnect is capable of expanding when one or more of the free slot symbols are each replaced by a frame notify message indicating that the data has been stored by the switch for retrieval by the one or more destination network devices.

摘要： Methods and apparatus for providing a source interface device and destination interface device are disclosed. A method of enabling communication between the source device and one or more destination devices includes sending data from the source device to the switch for storage. A frame notify message addressed to the one or more destination devices and indicating that the data has been stored by the switch for retrieval is then sent on the ring interconnect. One of the specified destination devices obtains the frame notify message from the source device via the ring interconnect. A frame retrieval message identifying the data is then sent from the destination device to the switch in response to the frame notify message. In addition, the destination device modifies the frame notify message to indicate whether the destination device was capable of accepting the frame notify message. The modified frame notify message is then sent on the ring interconnect for retrieval by another destination device or the source device.
