摘要： A method for connecting a first communication system with a third communications system, by passing through a second communications system, is disclosed. A first frame is received from the first communications system, where the first frame has a multicast address as a destination address. The multicast address requires the frame to be transmitted onto the second multicast address is translated into a functional address. The functional address is written into a second frame, and the second frame is transmitted onto the second communications system. A station receiving the second frame translates the functional address into a multicast address and writes the multicast address into the destination address field of a third frame, and transmits the third frame onto the third communications system.

摘要： A connection apparatus for connecting a first communication system with a second communication system and a third communication system. A first frame is received from the first communication system, where the first frame has a multicast address as a destination address, and where the destination address requires the first frame to be transmitted onto the second communication system. The multicast address is translated into a functional address, and the functional address is written into a second frame transmitted onto the second communication system. The second frame is received and is transmitted onto a third communication system, and the functional address is translated into a multicast address for the third communication system, and the multicast address is written into a destination field of the frame as it is transmitted onto the third communication system. The second communication system may be a token ring system based upon an IEEE 802.5 standard, and the functional address may be written into a DSAP field and into a PROTOCOL TYPE field of an 802.5 Standard frame.

摘要： An apparatus for forwarding a data packet from a first link to a second link is disclosed. The apparatus is coupled with a plurality of computer networks through ports on the apparatus. The apparatus maintains a spanning tree list indicating which of the apparatus ports are active. The apparatus receives a packet, and determines if the packet was received from a port that is active. If the packet was received from a port that is not active, the packet is discarded. If the packet is not discarded, the data link source address of the packet is stored in a database within the apparatus for the computer network coupled with the port from which the packet was received. The apparatus then decides, responsive to a contents of a data link destination address field in the packet, whether to forward the packet as a bridge or to forward the packet as a router. If the apparatus forwards the packet as a router, the apparatus sends a redirect message to update the data link layer destination address used by the originating station to contain the data link layer address of the destination station where the destination station is on a link remote from the link of the originating station. For the subsequent packets the apparatus then behaves as a bridge by forwarding the subsequent packets based upon parsing of only the Data Link Header. For forwarding of subsequent packets, the apparatus is advantageously fast, in accordance with bridge operation.

摘要： An access point in a wireless network includes an external indication of the access point's proximity to another access point. The external indication can be a LED that blinks at a rate that is related to the proximity of the access point to the other access point. An access point is also capable of producing a network map that indicates the access point's proximity relative to other access points that are coupled to the network. The access point is further capable of monitoring wireless network traffic to ascertain whether wireless network traffic has exceeded a threshold, and if so, releasing some client devices so that wireless network traffic no longer exceeds the threshold. The access point is also capable of automatically choosing one of a plurality of radio frequencies on which to operate. The access point chooses a frequency after evaluating frequencies on which other access points may be operating.

摘要： A wireless access point is operable to tag packets received from mobile clients. For example, a VLAN tag or Layer-3 tunnel tag for a packet is determined based at least in-part on a mapping between a mobile client and tag maintained by the access point. In one embodiment the access point uses Association IDs (“AIDs”) to uniquely identify mobile clients in the BSS. Hence, the mapping is between A/Ds and VLAN tags/Layer-3 tunnel tags. The mapping may be generated by snooping authentication related communications or from information maintained by a switch, such as a MAC address to tag mapping.
摘要翻译：无线接入点可用于标记从移动客户端接收的分组。例如，分组的VLAN标签或第3层隧道标签至少部分地基于移动客户端与接入点维护的标签之间的映射来确定。在一个实施例中，接入点使用关联ID（“AID”）来唯一地识别BSS中的移动客户端。因此，映射在A / D和VLAN标签/三层隧道标签之间。可以通过窥探认证相关的通信或者由交换机维护的信息（例如MAC地址到标签映射）生成映射。
