A network management system for a multi-layer network having multiple architectural or technological domains includes an inter-domain configuration manager arranged between a set of one or more network service management applications and a set of network element domain managers, each of the domain managers being associated with a particular domain of the multi-layer network. The configuration manager implements network service design and provisioning functions across the domains of the network in conjunction with stored connectivity information characterizing the multi-layer network. The network management system further includes an inter-domain fault manager and an inter-domain capacity manager, which provide respective fault management and transport capacity management functions across the domains of the multi-layer network. The inter-domain configuration manager, inter-domain fault manager and inter-domain capacity manager may be interfaced to the set of network service management applications and the set of network element domain managers through corresponding published Common Object Request Broker Architecture (CORBA) Application Programming Interfaces (APIs).

A gateway between client manager applications and an enterprise manager may be provided to manage various networked objects. In one embodiment, CORBA-based TMN manager applications may be communicatively coupled to a CORBA Object Request Broker (ORB) and may be operable to send Interface Definition Language (IDL) requests to, and receive IDL responses and CORBA events from, managed objects through the CORBA ORB. The client manager may first be authenticated to the gateway by username and password, or other validation information associated with the client manager, which may be represented in a user profile. Once the initial client authentication is accomplished, the gateway may provide object-level access control between manager applications and managed objects at an individual object level so that one of the managers is granted access to one of the managed objects while being prevented from interfacing with a different one of the managed objects.

The disclosure relates to systems, apparatus, and methods of reducing round trips associated with DNS lookups in ways that are substantially transparent to the user. Embodiments implement prefetching of DNS entries, sometimes piggybacking on the prefetching of associated web objects. In one embodiment, prefetching of an object continues according to other prefetching techniques, until the point where the HTML response may be parsed. When an embedded object request is identified, a DNS lookup is performed, and the resulting IP address is pushed to the client as part of a prefetch data package. In some embodiments, the client strips off the relevant portion of the prefetch data package to create a local DNS entry. The DNS entry may be used to locally handle DNS requests by the client, thereby potentially avoiding a round trip to a remote DNS.

A web server configured to respond to client requests over a network such as the World Wide Web includes a web listener having a Hypertext Transfer Protocol (HTTP) daemon, a plurality of extension programs configured to perform respective operations, and a web request broker configured to identify one of the programs for responding to a client request, and determine the availability of an instance of the identified program. The web request broker maintains control of multiple instances of each server extension program to provide enhanced server operation without overwhelming server resources. The web request broker maintains a minimum number of instances of the identified program in memory, each executed in its own address space. The web request broker determines whether an available instance of the identified program is available from an existing number of instances, and selectively initiates a new instance of the program if no other instance is available. If no instance is available and the existing number of instances exceeds the maximum prescribed number, then the web request broker returns the reply to the web listener to send a reply over the network that the request was not processed.

According to the method, the seamless splicing for the ultrahigh resolution images is realized, the time for splicing is reduced, the splicing efficiency is increased and the beneficial effect on the high-definition image is achieved.

A system and method for managing network devices using a metadata gateway. The metadata gateway provides translation of metadata to and from a database format and Interface Definition Language (IDL), which is operable across a plurality of platforms and across a plurality of programming languages. Metadata may be retrieved through the metadata gateway by a client manager application sending a request for type information for a managed object attribute or event in IDL through a CORBA Object Request Broker (ORB) to the metadata gateway, which then reads the type information from a metadata repository, where the type information is stored in a database format. The metadata gateway then translates the retrieved type information from the database format to IDL and sends the translated type information to the ORB, which sends the translated type information for the attribute or event to the client manager application. Metadata may be encoded through the metadata gateway by sending the metadata in IDL to the metadata gateway, which translates the type information from IDL to a database format and stores the type information in the metadata repository.
