摘要:
Operations in a worksite (20) are managed by networking at least some items of apparatus (4, 16, 24, 26, 30, 28, 34) which perform tasks in connection with said worksite and which receive and/or send data. The items of apparatus are organized in hierarchical levels according to a determined dependency relationship of the worksite. Communications are made with an electronic data network comprising management means (74, 76, 66, 64) cooperating with a plurality of communications interfaces (42-46), a given item of apparatus having a data link with a specified communications interface. The management means stores a correspondence between each item of apparatus and an address structure reflecting the hierarchical position of that item of apparatus (4, 16, 24, 26, 30, 28, 34) in the determined dependency relationship of the worksite. It uses that correspondence to establish a communications link with a selected item of apparatus, via its communications interface, in response to a call addressed with an address structure reflecting the hierarchical position of that selected item of apparatus.

A secure domain name service for a computer network is disclosed that includes a portal connected to a computer network, such as the Internet, and a domain name database connected to the computer network through the portal. The portal authenticates a query for a secure computer network address, and the domain name database stores secure computer network addresses for the computer network. Each secure computer network address is based on a non-standard top-level domain name, such as .scom, .sorg, .snet, .snet, .sedu, .smil and .sint.

A method for retrieving data from a network having network elements in a multi-level hierarchical tree includes providing a data exchange interface defining formats for requesting and delivery of types of data to be retrieved, generating a request at the data exchange interface to define the data to be retrieved, using the request to define a canonical name and a depth indicator, implementing, at one or more levels in the network, a data retrieval routine that uses the canonical name to generate a command that is issued to the element or elements from which data are to be retrieved to cause the element or elements to return data including a description and a value, and communicating the returned data to the data exchange interface in the defined data format.
摘要:
A technique for examining the relationships of autonomous systems (ASes) participating in an Internet Exchange Point (IXP) utilizes packet tracing servers proximate the IXPs. Where such packet tracing servers cannot be found in the participating ASes, the methodology identifies additional vantage points by looking at a list of ASes that are one hop away from the ASes at the IXP. The choice of one-hop away ASes is made judiciously by picking ones that have better connectivity, based on past-data. Plural-hop ASes may also be used where necessary.
摘要:
One embodiment of the present invention provides a system for looking up location-specific configuration information for a network node or a subnet. During system operation, a network node creates a query message containing a key that comprises an Internet Protocol (IP) prefix and a string, wherein the IP prefix identifies the network node or the subnet, and the string specifies the type of configuration information. The network node then sends the query message to a name server, which is part of a distributed system that provides a global naming service, wherein the name server additionally stores configuration information. Finally, the network node receives a response message from the name server, wherein the response message contains the requested configuration information.

A top-level domain (TLD) hierarchical routing system comprises a domain name server (DNS) configured to analyze a universal resource locator (URL) top-level domain (TLD) and to route an Internet query to a numerical Internet protocol (IP) destination; a proprietary server Internet-coupled with the numerical Internet protocol (IP) destination, the server configured to analyze one or more second-level domains (SLDs) behind the TLD and further to provide an operative engagement between an Internet user and a value-added service in the form of a software-as-a-service (SaaS) or application software program (ASP) relatable to selected ones of plural SLDs that are licensed or otherwise authorized to use the TLD, thereby to add value to the one or more SLDs and to the one or more users sharing such a ubiquitous Internet-based value-added services platform.
摘要:
Service resource items (49) for use in call setup in a telephone system are held on servers (58) that are connected to a computer network which is logically distinct from the telephone system infrastructure; this computer network may, for example, make use of the Internet. Each service item (49) is locatable on the network at a corresponding URI and is associated with a particular telephone number. A mapping is provided between telephone numbers and the URIs of associated service resource items. When it is desired to access a service resource item (49) associated with a particular telephone number, this mapping is used to retrieve the corresponding URI (step 55) which is then used to access the desired service resource item (56, 57, 59).
摘要:
Techniques for discovering and/or advertising services are described herein. A first bitmask is received from a remote device over a wireless network, the first bitmask having one or more bits that have a predetermined logical value. Each bit represents a particular service provided by the remote device. A logical operation is performed between the first bitmask and a second bitmask locally generated within a local device, where the second bitmask represents a service being searched by the local device. It is determined whether the remote device is potentially capable of providing the service being searched by the local device based on a result of the logical operation.
摘要:
Systems and processes include a disaster recovery system for a production site. The disaster recovery site may include replications of at least a portion of information and/or applications from the production site. Requests for the production site may be redirected to the disaster recovery site according, as appropriate. The disaster recovery site may be tested while without substantially inhibiting operation of the production site
摘要:
Methods and apparatus enable a femto radio base station (28f) to be connected to an appropriate radio network controller node (26) of a radio access network (24) for use as an active radio network controller node for the femto radio base station. The connection is accomplished the femto radio base station (28f) preparing a node address inquiry and for using the node address inquiry for obtaining an internet protocol (IP) address of an appropriate radio network controller node. The femto radio base station (28f) further uses the internet protocol (IP) address of an appropriate radio network controller node for connecting to the appropriate radio network controller node as its active radio network controller node.
