摘要： In a distributed switching environment, a plurality of switches are clustered together to form a stack, and it is generally desirable for forwarding tables, such as MAC tables, to be synchronized so that their mappings are consistent. When a switch receives a packet having a source address (e.g., MAC address) that is unknown, the switch is configured to disseminate the source address to the other switches of the stack. Rather than using software protocols to disseminate the source address, the switch instead transmits a multicast packet that (1) includes the unknown source address and (2) spoofs the other switches into believing that the packet was received on the same port from which the unknown source address was received on ingress to the stack. Thus, the other switches learn the unknown source address in hardware without having to rely on software for updating their forwarding tables.

摘要： A midspan device for providing power and data from a one-pair power sourcing equipment to a two-pair powered device is described. The midspan device is connected to the one-pair power sourcing equipment and takes a portion of the power from the power sourcing equipment to power a converter. The converter converts one-pair data into a two-pair data and forwards the converted data to the two pairs of the powered device. Another portion of the power from the power sourcing equipment is on a DC path and coupled through center tap transformers to provide power to the powered device.

摘要： A differential time domain digital communication bridge module interfaces 100 Mbps Ethernet traffic with a T3 communication link, using a relatively small sized data buffer. To avoid dropping packets, the relatively large sized buffer in the Ethernet switch is used to temporarily store packets, in when an upper threshold of the storage capacity of the buffer is reached. The upper threshold leaves enough storage overhead in the buffer to allow the Ethernet switch to complete its current transmission of a maximum length packet. When a lower threshold is reached a ‘resume transmission’ packet is sent to the switch. The lower threshold provides sufficient buffer space to allow the T3 transmitter to read out the contents of the buffer without underflow.
摘要翻译：差分时域数字通信桥模块使用相对较小尺寸的数据缓冲器将具有T3通信链路的100Mbps以太网业务与100Mbps以太网流量进行接口。为了避免丢弃数据包，当达到缓冲区的存储容量的上限阈值时，以太网交换机中相对较大的缓冲区用于临时存储数据包。上限阈值在缓冲区中留下足够的存储开销，以允许以太网交换机完成其当前最大长度数据包的传输。当达到较低的阈值时，将“恢复传输”数据包发送到交换机。较低的阈值提供足够的缓冲空间，以允许T3发送器读出缓冲器的内容而不会下溢。
