A loop carrier system includes a home local area network having plural telephone modules and a hub coupled to in-home telephone wiring. The telephone modules and the hub communicate voice signals over the in-home wiring in a dedicated frequency band above baseband POTS.

The invention discloses a JACA remote invocation method in a CORBA (Common Object Request Breaker Architecture) system. The method comprises the steps of: receiving an invocation request of a user, restructuring the invocation request through JACA dynamic proxy and interception, converting the invocation request into a CORBA service-oriented request, and realizing remote invocation by invocating a similar standard CORBA core through a pre-packaged CORBA interface. When a user carries out remote JAVA invocation, the invention ensures that the user does not need to pay attention to a specific invocation implementation process or implement a specific CORBA interface, thereby greatly reducing the work load on the prophase development and later-stage maintenance of the JAVA remote invocation which can be implemented easily.

In a preferred embodiment, requesters are categorized and identified by their roles in the enterprise. Only those requesters having a proper role are authorized to access the requested object.

A method, apparatus, and computer implemented instructions for binding object references from a remote name space into a local name space using a Web application. Information is collected to generate a request for an object reference. Information, such as an application server to use as the source, a source name space path, an identification of destination server, and a destination name space path to which the object reference is to be bound, may be used. The request is sent using a communications protocol, such as hypertext transfer protocol to the application server to be used as the source for the object reference. An object reference is located using the name space. The object reference may be serialized into a format, such as a common object request broker architecture format and sent to the destination. The destination will unserialize the object reference and perform binding using the destination name space path.

Communications using the common object request broker architecture (CORBA) is disclosed. The communications are between a first computing device and a second computing device separated by a NAT device. The first computing device issues a request conforming to the CORBA protocol to obtain an IOR for an object from the second computing device. A first request interceptor on the first device adds a public IP address of the second computing device as user-defined data in the request. A second request interceptor on the second computing device extracts the IP address from the request and stores it. The second computing device builds the IOR for the object including embedding the public IP address of the second computing device in the IOR. The second computing device sends the IOR to the first computing device. The first computing device then establishes a successful connection to the public IP address received in the IOR.

A method and system for allowing a PERL application to communicate with distributed objects. One embodiment comprises a method in which first an adapter program receives a request from a PERL application. The PERL request specifies a distributed object with which the PERL application desires to communicate. The adapter program translates the request from the PERL application. For example, the adapter program translates PERL data structures into a format which is compliant with a communication program. Then, the adapter program calls the communication program to access the distributed object via Common Object Request Broker Architecture (CORBA). After the adapter program receives a response from the communication program, the adapter translates the response to a form suitable for the PERL application. For example, the adapter program may need to translate a data structure into a PERL compliant form. Then, the adapter program passes the response to the PERL application.
