URL based communication protocol from a client computer to a network device
A method of signaling in a computer network uses interception by a network device of a message transmitted by a client computer to a server. The message contains a Universal Resource Locator (URL), the URL having a reserved port designation. The network device parses the URL and intercepts the message in response to finding the reserved port designation in the URL. The network device executes a command, where the command is carried in a field of the intercepted message. The client computer receives the URL having the reserved port designation in a HTML file transmitted to the client computer by the server. The message containing the URL is transmitted by the client computer in response to a user requesting a resource displayed in a web page displayed by the client computer. A second web page is transmitted to the client computer by a server receiving a request for services, and the URL containing the port designation is written into the second web page so that the URL is executed automatically as the second web page is received by the client's browser. The method transmits a redirect message by the network device to the client computer, the redirect message redirecting to an address of a web page without the reserved port designation in the URL to carry information to the server. |

System for automated reply to natural language input
Method and agent network architecture for processing a subject message, where each agent has a view of its own domain of responsibility. An initiator agent which receives a user-input request and does not itself have a relevant interpretation policy, queries its downchain agents whether the queried agent considers such message to be in its domain of responsibility. Each queried agent recursively determines whether it has an interpretation policy of its own that applies to the request, and if not, further queries its own further downchain neighboring agents. The further agents eventually respond to such further queries, thereby allowing the first-queried agents to respond to the initiator agent. The recursive invocation of this procedure ultimately determines one or more paths through the network from the initiator agent to one more more leaf agents. The request is then transmitted down the path(s), with each agent along the way taking any local action thereon and passing the message on to the next agent in the path. In the event of a contradiction, the network is often able to resolve many of such contradictions according to predetermined algorithms. If it cannot resolve a contradiction automatically, it learns new interpretation policies necessary to interpret the subject message properly. Such learning preferably includes interaction with the user (but only to the extent necessary), and preferably localizes the learning close to the correct leaf agent in the network. |

At registration, techniques detect repeated elements in the XML schema and analyze whether the repeated elements are from the same complex type. If so, techniques perform additional analysis to determine a minimal common ancestor. Within the context of a minimal common ancestor, techniques determine the maximum number of times an element may occur in the schema. In a choice content model, the largest maximum occurrence value is selected. In other content models, the maximum occurrence value is determined by adding together the occurrence values for the repeated elements. Then, when an object relational table is generated for the XML schema, the maximum number of times that an element appears in the schema is this value. Techniques retain the advantages of object relational storage, even after a schema evolution. |

Method for reordering and reassembling data packets in a network
A method is described that is operable to reorder and reassemble data packets from network traffic into unfragmented and in-order traffic flows for applications such as deep packet classification and quality of service determination. A queue engine stores incoming data packets in a packet memory that is controlled by a link list controller. A packet assembler extracts information from each data packet, particularly fields from the header information, and uses that information among other things, to determine if the data packet is fragmented or out of order, and to associate the data packet with a session id. If the packet is determined to be out of order, the queue engine includes a reordering unit, which is able to modify links with the link list controller to reorder data packets. A fragment reassembly unit is also included which is capable of taking fragments and reassembling them into complete unfragmented data packets. The reordered and reassembled data packets are then sent to an output where further operations such as deep packet classification can take place. |

The virtual disks will have two or more actuators, one for each virtual disk, improving performance for the capacity of the platters through concurrent data seeks and transfers to different data areas. |
