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.

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.

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.

A method for forwarding data packets to one of a plurality of servers comprising receiving a data packet from a source, at a data packet forwarding device having a plurality of ports, performing a hashing function using a unique component of the data packet as a seed value for the hash, generating a hash value using the hashing function, looking up a table for an address of one of the plurality of servers using the hashed value as an index to the table, and forwarding the data packet to a server corresponding to the address.

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.

This invention relates to methods for identifying potentially infected files downloaded to a digital display device (“DDD”) and for managing those potentially infected files. These methods may include the steps of: connecting the DDD to a device; downloading one or more files to the DDD; disconnecting the DDD from the device; verifying and repairing the boot sector of the DDD; removing the one or more downloaded files that are not supported for playback on the DDD; and scanning the one or more downloaded files that are supported for playback on the DDD.
摘要:
A method and system is provided in which MAN traffic is segregated at a customer and a provider domain level. A switch at the edge of the MAN encapsulates a data packet in a new header, which is used to specify the customer domain tags. The data packet is encapsulated further in another new header, which is used to specify new VMAN tags. The nested encapsulation is repeated as necessary until the data packet is forwarded to a remote switch at the edge of the MAN in accordance with the VMAN configuration or the source and destination address in the original data packet. The remote switch strips the VMAN tags from the data packet, and forwards the stripped data packet to the receiving customer domain as specified in the customer domain tag.
