摘要： A software reload is executed. The hardware associated with the network device continues to forward network traffic during the software reload. Also, a kernel of the network device operates unaffected in a protected address space throughout the software reload. Further, the kernel preserves local checkpointed and shared memory data. Application processes running on the network node are shut down gracefully. The reloaded software is brought up and the network device is resynchronized.

摘要： A network infrastructure element such as a router or switch performs transparent and optimized validation of XML schemas of XML payloads received in the network element. The network element comprises logic for receiving and storing one or more validation scope rules that define a portion of an extensible markup language (XML) schema for validation; receiving and storing the XML schema; receiving over the network an application-layer message comprising one or more of the packets; identifying a particular XML element in an XML payload of the application-layer message, wherein the particular XML element is within the portion of the XML schema defined in the one or more validation scope rules; determining whether the particular XML element conforms to the XML schema; and performing a responsive action based on whether the particular XML element conforms to the XML schema.

摘要： A network provisioning system for establishing a path between two networks is disclosed wherein a common network device between those networks is modeled as a link between a first network element in one network and a second network element in a second network. A network routing graph is created by an inventory subsystem in a routing manager by inventorying the physical network elements and links in the network. The inventory subsystem then models those elements/links as a plurality of nodes and links between the nodes. At least one common network device, such as a digital cross connect connecting the two networks, is modeled as a link instead of a node. A routing engine then uses the network routing graph, including the link modeled from the common network device, to provision a path between the networks.

摘要： A method and apparatus for performing an in-service upgrade of a switching fabric of a network element is described. Network traffic is denominated in cells as it passes through the network element. Prior to the upgrade, an internal header is provided to direct the communication of a cell through the network element. The internal header has internal routing information to direct the routing of the cell through the switching fabric of the network element. Additional internal routing information compatible with upgraded components of a network element is added to the cells passing through the network element. The additional internal routing information is dependent on the internal routing information previously provided in the internal header, but differs from the internal routing information in that it supports the upgraded components of the network element. Thus, prior to the upgrading of a switching fabric in a network element, the internal routing information is used to route the cells through the non-upgraded network components, while, after the upgrading of the switching fabric, the additional internal routing information is used to route cells through the upgraded components of the network element.

摘要： Custom or user-defined application program extensions may be loaded into a network infrastructure element such as a router or switch without restarting the device. For example, a network element has program extensibility logic operable for receiving one or more user program extensions that comprise logic operable to interface with the application program and perform message processing functions or protocol processing functions that are not in the application program; installing the one or more user program extensions without restarting the apparatus; receiving one or more packets representing an application message; selecting a particular one of the user program extensions based on a protocol associated with the message; loading the particular one of the user program extensions; executing business logic of the application program associated with the received message; and invoking a function of the particular one of the user program extensions in response to a call in the business logic.

摘要： A multi-network system is provided with a facility for storing an old or superseded router image without the need for increasing router memory. A local storage device is coupled, directly or indirectly, to a router. Before a new image is downloaded to the router, the old or superseded image is first stored in the support device. If the new image is defective or undesirable, the old image can be recovered, even if the wide area link is unopenable, by reloading the old image from the local storage device.
