摘要： An integrated circuit (203) for use in processing streams of data generally and streams of packets in particular. The integrated circuit (203) includes a number of packet processors (307, 313, 303), a table look up engine (301), a queue management engine (305) and a buffer management engine (315). The packet processors (307, 313, 303) include a receive processor (421), a transmit processor (427) and a risc core processor (401), all of which are programmable. The receive processor (421) and the core processor (401) cooperate to receive and route packets being received and the core processor (401) and the transmit processor (427) cooperate to transmit packets. Routing is done by using information from the table look up engine (301) to determine a queue (215) in the queue management engine (305) which is to receive a descriptor (217) describing the received packet's payload.

摘要： A system and method that facilitates the configuration and control of components of a radio frequency identification (RFID) system, taking into account how the RFID system components are associated with one or more physical locations within an environment in which the RFID system is deployed. The RFID system can be controlled by obtaining a representation of the physical space. Next, at least one region of interest is specified in the representation of the physical space. An interrogation zone is then specified in the representation of the physical space, in which the interrogation zone corresponds to the data reader. Next, at least one overlap region of the interrogation zone and the region of interest is specified. Information is then stored, including the representation, and the interest region, the interrogation zone, and/or the overlap region. Operation of the data reader is controlled as a function of the stored information.

摘要： A method and apparatus are disclosed which permit multipoint trunking among a plurality of network devices connected by a trunk comprising at least two physical links. A trunk control message protocol (TCMP) is described which assures that message traffic may be delivered to the respective devices over the individual links of the trunk prior to inclusion of the respective links as active links in the trunk. The trunk acts as a single network port for each of the devices utilizing the trunk and is layered over a plurality of media access control (MAC) ports which interface to the respective links. The disclosed trunking technique and apparatus permit the bandwidth of the trunk to be increased in increments through the addition of links to the trunk.

摘要： A live insertion and removal mechanism assures that a sub-assembly being inserted or removed from a live electronic assembly does not disrupt system power and buses and is protected against the negative affects of current surge. An active current control device and related circuitry, and a connector having a plurality of graduated pin lengths effect a controlled ramp-up and ramp-down of power to the sub-assembly inserted into and removed from the live electronic assembly. Additionally, means are provided for effectively disconnecting selected output drivers from signal and control paths to avoid damage to the drivers upon insertion or removal of the sub-assembly from the live assembly.

摘要： A technique for more directly transmitting information between devices in different virtual local area networks ("VLANs") in a local area network ("LAN") is disclosed. A VLAN tag is used to forward a packet into the VLAN in which the destination device resides by attaching the VLAN tag associated with the destination device to each transmission. Devices that are not associated with the VLAN specified by the VLAN tag are thereby segregated from the packet and LAN background traffic overhead is reduced. To determine the appropriate VLAN tag the sending device transmits a NHRP query requesting connectivity information between the sender and receiver, and the receiver or an intermediary router responds with information including the VLAN tag of the receiver. Packets of data are then sent from the sending device to the receiving device with the VLAN tag of the receiver attached thereto so that a more direct connection is established with bridge hops replacing router hops.
摘要翻译：公开了一种用于在局域网（“LAN”）中的不同虚拟局域网（“VLAN”）中的设备之间更直接地传送信息的技术。 VLAN Tag用于通过将与目标设备相关联的VLAN标签附加到每个传输中来将数据包转发到目标设备所在的VLAN中。与VLAN标签指定的VLAN不相关的设备因此与数据包隔离，LAN背景流量开销减少。为了确定适当的VLAN标签，发送设备发送NHRP查询请求发送方和接收方之间的连接信息，接收方或中介路由器以包含接收方VLAN标签的信息进行响应。然后将数据包从发送设备发送到具有接收者的VLAN标签的接收设备，以便建立更直接的连接，桥接跳跃替代路由器跳。

摘要： A system and method that facilitates the configuration and control of components of an RFID system, taking into account how the RFID system components are associated with one or more physical locations within an environment in which the RFID system is deployed. A user provides information specifying associations between the system components and the physical locations within the environment to obtain visual representations of configuration data generated therefrom with reference to a facility view, an RF coverage view, and a location view of the data. The facility view serves as a reference plane for placement and orientation of antennas associated with RFID readers, location benchmark tags, and the physical locations of interest. After each antenna is placed and oriented on the facility view, an estimate of the size and shape of the RF interrogation zone of each antenna is computed, and representations of the RF interrogation zones are provided on the facility view to obtain the RF coverage view of the data. Next, the user provides information specifying the physical locations of interest to obtain the location view of the data. A composite of the facility view, the coverage view, and the location view is then generated to obtain an enhanced visual understanding of how the system components and the physical locations exist within the system environment, and how the components and locations are associated with one another.
