摘要： A method and apparatus is provided to restore the configuration of a network device. A configuration manager in a network device saves a version of the configuration of the network device by storing the configuration data in an format that conforms to a standard markup language such as the extended markup language (XML). The format includes a sequence of corresponding tags and values that represent the content of the internal data structures in the memory of the router that comprise the saved version of the configuration. At the time of restoration, an parser is used to parse the values from the tags and the configuration manager restores the contents of the internal data structures in the memory of the router to the parsed values in accordance with the corresponding tags.

摘要： The present invention relates to methods for dynamically displaying images on a display window of a digital display device such as a digital picture frame. These methods include the steps of: processing the source image into a canvas image having canvas pixels as a function of the source image characteristics; upon the canvas image meeting one or more conditions for the panning of an image, selecting a panning velocity for the canvas image; defining a viewing window with respect to the canvas image wherein said viewing window having a viewing image, said viewing image is to have a plurality of viewing pixels; calculating the viewing pixels for said viewing image; displaying said viewing image for said viewing window on said display window; redefining said viewing window with respect to the canvas image as a function of said panning velocity; and repeating the calculating and displaying steps for said viewing window. These methods allow for the dynamic display of images with special effects on a digital display device as a function of the properties of the image (e.g. a panoramic image). They also provide for the smooth panning of digital images at velocities that are accurate up to fractional pixels per unit time.

摘要： A method and system is provided for increasing participation in a standby router protocol (SRP) without increasing the amount of network traffic due to SRP messaging. One or more domain master VLANs participate in an SRP on behalf of numerous member VLANs belonging to the domain master VLAN's domain. The domain master VLANs are associated with at least one virtual router. Each domain member VLAN follows the current default routing configuration for the domain master VLAN as determined in accordance with the SRP election process defined for that virtual router. An end-host attached to a host-specific port on an SRP router participates in the SRP by using a router bridge connection established between the SRP router and other SRP routers supporting the virtual router. Each end-host on a host-specific port follows the current default routing configuration implemented by the current master SRP router as determined in accordance with the SRP election process defined for that virtual router.

摘要： A method and system is provided in which data packets from multiple customer VLANs are forwarded over a MAN using VLAN aggregation. A layer-2 switch located at the edge of the MAN connects the customer VLANs to the MAN. The edge switch aggregates multiple customer VLANs (the “sub-VLANs”) into one provider VLAN (the “super-VLAN”). When a packet is forwarded from the sub-VLAN to the super-VLAN and vice versa, the edge switch uses modified bridge forwarding rules to exchange the customer-configured VLAN-IDs with the provider-configured VLAN-IDs before transporting the packet over the MAN. The edge switch further uses modified bridge media access control (MAC) address learning rules to isolate one customer's traffic from another's (i.e. isolate one sub-VLAN's traffic from another sub-VLAN's traffic).

摘要： In a data network, a source node transmits a data packet to a destination node across interconnected switches whereby a switch, upon receiving the data packet from the source node, queries other switches in the network for the appropriate switch and port on the switch out which to forward the data packet to the destination node. The appropriate switch responds to the query with its switch number and the port number of the port out which the data packet should be sent to reach the destination node. The querying switch caches the switch number and port number and prepends a destination tag to subsequent data packets it receives which are destined to the same destination node, thereby providing a distributed system among the switches in the network for maintaining detailed information regarding the appropriate switch and port out which to forward data packets received by a source node in the network.

摘要： A packet switching device having a central shared memory and a number of medium access controllers each coupled to a communications medium to exchange data packets therewith, and a controller coupled to each medium access controller via a data path to exchange data packets with the media access controller. The controller has a number of data path controllers each connected to each medium access controller via a separate and like portion of the data path to exchange a corresponding portion of the data packets with the medium access controller. The data path controllers each have a number of buffers each connected to one of the medium access controllers to which the data path controller is connected, to hold the portion of the data packets exchanged with the corresponding medium access controller. Each data path controller has a selector that selects the buffer from which to transmit or receive the portion of the data packets with the central shared memory and control logic that controls the selector to concurrently select the buffer corresponding to the same medium access controller. A comparison engine associated with each data path controller detects the slice of a field in a data packet buffered in the corresponding data path controller and computes a hashing function on the contents of the slice of the field to generate a hash key. A packet forwarding controller reads one or more entries from a hash bucket in a forwarding database indexed by the hash key and sends the entries to the comparison logic. The comparison logic compares the slice of the field in the buffer to each of the entries and returns the results of the compare to a packet forwarding controller. The forwarding controller then forwards, filters or identifies packets based on the results of the comparisons done on each slice of a field in the packets.

摘要： A network interconnect device and message exchange protocol for forwarding data among packet forwarding devices are provided. According to one aspect of the present invention, data is forwarded between a first and second packet forwarding device coupled to an interconnect device. The interconnect device receives a menu message from the first packet forwarding device that indicates one or more types of data that are awaiting transmission on the first packet forwarding device. Based upon the menu message, the interconnect device transmits an order message selecting a type of data of the one or more types of data awaiting transmission to the first packet forwarding device. The interconnect device receives a message from the first packet forwarding device containing data of the type selected by the order message. The interconnect device then forwards the data to the second packet forwarding device. According to another aspect of the present invention, data is forwarded among multiple packet forwarding devices through an interconnect device by selecting a configuration of the interconnect device based upon ports to which the packet forwarding devices have data to transfer. For each of the ports of the interconnect device, an indication of ports to which an attached packet forwarding device has data to transfer is received. Based upon these port indications, a configuration of the interconnect device is selected that contains non-conflicting paths through the interconnect device. Data is then forwarded in accordance with the selected configuration by forwarding data from those of the of packet forwarding devices coupled to ports that have been selected as source ports to corresponding destination ports.
