摘要： A method is disclosed that enables the avoidance of a processor overload of a telecommunications endpoint device that is susceptible to traffic floods. An enhanced network switch sets the speed on one of its data ports as a specific function of the speeds of the devices that are donnected to one or more of its other data ports. This behavior is different from that of network switches in the prior art, in which the data rate of a port in the prior art is auto-negotiated to the highest speed that can be supported by the network elements at either end of the port's connection, regardless of the other devices present. By considering the specific devices that are connected, the enhanced network switch is able to limit the amount of traffic that is directed by an upstream device, such as a router, towards a device with limited processor capability, such as a packet-based phone.

摘要： A method is disclosed that enables the transmission of a digital message along with a corresponding media information signal, such as audio or video. A telecommunications device that is processing the information signal from its user, such as a speech signal, encodes the information signal by using a model-based compression coder. One such device is a telecommunications endpoint. Then, based on an evaluation of the perceptual significance of each encoded bit, or on some other meaningful characteristic of the signal, the endpoint's processor: (i) determines which encoded bits can be overwritten; and (ii) intersperses the digital message bits throughout the encoded signal in place of the overwritten bits. The endpoint then transmits those digital message bits as part of the encoded information signal. In this way, no additional bits are appended to the packet to be transmitted, thereby addressing the issue of compatibility with existing protocols and firewalls.

摘要： A method and an apparatus are disclosed that provide a privilege-granting technique for enabling a service-providing domain to grant a privilege to a requesting user in a service-requesting domain. A request handler (221) in the service-providing domain, which comprises one or more service-associated resources, receives a user request to use a service and requests a token from a privilege-granting server (223), in accordance with the illustrative embodiment of the present invention. Upon receiving the token that specifies a granted privilege from the privilege-granting server, the request handler extends the privilege to the requesting user. Alternatively, the request handler can request a plurality of tokens in advance from the privilege-granting server; after receiving the tokens, the request handler extends a privilege to each requesting user as the handler receives requests to use one or more services.

摘要： A method is disclosed that enables the implementation of an embedded firewall at a telecommunications endpoint. In particular, the illustrative embodiment of the present invention addresses the relationship between the application, firewall engine, and packet-classification rules database that are all resident at the endpoint. In the variations of the illustrative embodiment that are described herein, the application: (i) directly communicates with the co-resident firewall engine such as through local message passing, (ii) shares memory with the firewall engine, and (iii) makes socket calls to the operating system that are intercepted by a middleware layer that subsequently modifies the rules database, depending on the socket call. The common thread to these techniques is that the application, firewall engine, and rules database are co-resident at the endpoint, which is advantageous in the implementation of the embedded firewall.

摘要： A method is disclosed that enables the transmission of a digital message along with a corresponding information signal, such as audio or video. The supplemental information contained in digital messages can be used for a variety of purposes, such as enabling or enhancing packet authentication. In particular, a telecommunications device that is processing an information signal from its user, such as a speech signal, encrypts the information signal by performing a bitwise exclusive-or of an encryption key stream with the information signal stream. The device, such as a telecommunications endpoint, then intersperses the bits of the digital message throughout the encrypted signal in place of those bits overwritten, in a process referred to as "watermarking." The endpoint then transmits the interspersed digital message bits as part of a composite signal that also comprises the encrypted information bits. No additional bits are appended to the packet to be transmitted, thereby addressing compatibility issues.

摘要： A technique is disclosed that evaluates a network path between (i) a first node in a first subnetwork of endpoint nodes, such as IP phones, and (ii) a second node in a second subnetwork. A "ricochet" node in the network path evaluates the path by probing one or both subnetworks, where the ricochet node acts as relay for traffic packets being transmitted between the two subnetworks. A given relay has only to probe a single, representative node within a subnetwork at any given time in order to obtain performance data that is representative of the subnetwork overall. By probing the representative node, the relay is able to acquire an assessment of network conditions that is valid for the path between the relay and any endpoint in the subnetwork. As a result, the disclosed technique reduces the probing overhead when many endpoint nodes on a given subnetwork are simultaneously active and experiencing adverse network conditions.
