摘要： Methods, systems, and computer readable media for performing stateless load balancing of network traffic flows are disclosed. According to one aspect, the subject matter described herein includes a method for performing stateless load balancing of network traffic flows. The method occurs at a layer 3 packet forwarding and layer 2 switching device. The method includes responding to address resolution protocol (ARP) requests from clients, the ARP requests including a virtual IP (VIP) address shared by the device and a plurality of servers coupled to the device, with the medium access control (MAC) address of the device. The method also includes receiving, from the clients, packets addressed to the VIP address and having the MAC address of the device. The method further includes load sharing the packets among the servers using a layer 3 forwarding operation that appears to the clients as a layer 2 switching operation.

摘要： A flexible, policy-based, mechanism for managing, monitoring, and prioritizing traffic within a network and allocating bandwidth to achieve true quality of service (QoS) is provided. According to one aspect of the present invention, a method is provided for managing bandwidth allocation in a network that employs a non-deterministic access protocol, such as an Ethernet network. A packet forwarding device receives information indicative of a set of traffic groups, such as: a MAC address, or IEEE 802.1p priority indicator or 802.1Q frame tag, if the QoS policy is based upon individual station applications; or a physical port if the QoS policy is based purely upon topology. The packet forwarding device additionally receives bandwidth parameters corresponding to the traffic groups. After receiving a packet associated with one of the traffic groups on a first port, the packet forwarding device schedules the packet for transmission from a second port based upon bandwidth parameters corresponding to the traffic group with which the packet is associated. According to another aspect of the present invention, a method is provided for managing bandwidth allocation in a packet forwarding device. The packet forwarding device receives information indicative of a set of traffic groups. The packet forwarding device additionally receives information defining a QoS policy for the traffic groups. After a packet is received by the packet forwarding device, a traffic group with which the packet is associated is identified. Subsequently, rather than relying on an end-to-end signaling protocol for scheduling, the packet is scheduled for transmission based upon the QoS policy for the identified traffic group.

摘要： A method is provided to dynamically manage the configuration of a network device. An application supporting a protocol, network interface or other component of the configuration operates in conjunction with a master agent and subagent to send and receive configuration management information. The application further operates in conjunction with a configuration manager interface and configuration manager to access and update the configuration in accordance with a priority of the application, and without taking the network device out of service.

摘要： A rack mounted installation 200 comprises a rack 100 and a number of raceways 51, 52, 53 for routing cables to and from the rack 100. To route cables that are plugged into connectors 155 on any of a number of blades 150, the rack mounted installation 200 further includes a cable harness 300 which supports and channels the cables from the raceways 51, 52, 53 to the blades 150. There are also cable clips (800, Fig 8E), and bundle clips (1100, Fig 11A), which may be used individually or in combination, to perform cable management.

摘要： A multi-protocol packet translator is disclosed. The translator may have microcoded control to translate a packet from one protocol to another. The microcoded instructions may be fed through a pipeline to control reading of information from information sources (including the original packet) and selectively connecting those sources to an output memory.

摘要： A packet of data is received from a LAN and transmitted over a WAN, by retaining the native LAN frame format of the packet during transmission across the WAN. Thus, LAN data may be transmitted over a SONET point-to-point link within a WAN network without the interim steps of creating ATM cells or other WAN transport packaging protocols. Instead, the LAN data may be transmitted directly over the SONET link as raw data, and reconstructed directly at the receiving end of the SONET link. A first buffer stores data from the LAN so that a corresponding packet size may be determined, and a second buffer stores data from the WAN to account for any speed difference between the LAN circuitry and WAN circuitry.
