Telephone calls, data and other multimedia information is routed through a hybrid network which includes transfer of information across the internet. A media order entry captures complete user profile information for a user. This profile information is utilized by the system throughout the media experience for routing, billing, monitoring, reporting and other media control functions. Users can manage more aspects of a network than previously possible, and control network activities from a central site. The hybrid network also contains logic for responding to requests for quality of service and reserving the resources to provide the requested services.

A communication system providing telephony communication across combined circuit switched and packet switched networks, such as a telephone network and the Internet, which are connectable to terminals, such as telephones and computers, for selective communication therebetween. The communication system includes an authorization and account control object in the packet switched network, multiple gateways between the circuit switched and packet switched networks providing controlled connectivity between those networks, and an information retrieval object in the packet switched network, wherein the authorization and account control object maintains a substantially real time record of user accounts and usage, and the information and retrieval object provides substantially real time retrieval of selected information from the authorization and account control object. The retrieval object provides on demand to terminals which provide authentication for access to an identified account information regarding that account. The information regarding the account is substantially real time information including information with respect to communications in progress, which are chargeable to the account which has been authenticated. The authorization and account control object is preferably a unitary logical object having distributed instances thereof handling multitudinous accounts of widely separated terminals. The retrieval object provides isolation of the authorization and account control object permitting simultaneous multitasking by the authorization and account control object and the retrieval object respectively.

A callback system is created utilizing a hybrid telecommunication system including a switched communication network and a packet transmission network. A call parameter database is stored in a memory. A call is received on the system. The call parameter database is accessed to determine at least one call parameter. The call is routed over the switched communication network and the packet transmission network based on the at least one call parameter. A plurality of service engines is provided, each configured to execute desired service logic utilizing expert system.

Reservation controllers and reservation systems for reservation of access to multimedia multipoint telecommunications servers (MCUs) are provided. The reservation controller establishes a reservation domain having a reservation request channel on which reservation applications may be taken. An ongoing reservation conference is associated with the reservation domain. The reservation domain is preferably established within the ITU-T T.120 standard series requirements, with multipoint connection under T.122/T.125, and interface to profiles such as ISDN, TCP/IP, X.25, ATM, Ethernet, etc., under T.123. A user makes reservations for MCU resources by knowing the address of the reservation domain, attaching himself to the reservation domain, joining the reservation conference via establishing one or more transport connections, and sending the reservation request onto the reservation request channel. All reservation requests forwarded onto the reservation request channel are received and acted upon by the reservation controller. Reservation systems utilizing a plurality of reservation controllers are also disclosed, where the reservation controllers are part of the same domain, are arranged in multiple domains on a single level, or are arranged in hierarchical domains. Where more than one reservation domain is established, same-level or hierarchical level bridges are established.

A frame relay (FR) protection method generates an OAM frame to other nodes upon detecting a defect on a SONET ring. The protection frame comprises a type of failure and a location of failure. A node that detected the defect transmits the protection frame to other nodes about the location of the failure and the type failure. Protection tables are provided for switching a working fiber link to a protection fiber link. A protection switching provides a method re-establish FR traffic in spite of a detected failure on a SONET ring.

Availability is one of the most critical aspects of a network design. Despite that, few organizations have a good understanding of how much availability they really need. Factors such as budget constraints, limited time, or skills and experience of the staff at hand are what decide the network design and availability obtained. As a result, most organizations end up with solutions that have a sub-optimal level of availability. These solutions will have either too much availability or worse, too little. In the former case, the extra cost of the solution could be saved and used for other Information Technology (IT) projects. In the latter case, the lack of adequate network availability could impact operation, which ultimately can harm the financial performance of the organization. In both cases, organizations can lose money; hence the importance of selecting the adequate level of availability. This paper discusses different issues related to network availability. First, the paper presents some of the elements that impact the availability of a solution. Then the paper discusses how network designers can calculate the exact availability of their solution. Finally the paper provides means to determine the optimal level of availability. Using these elements, network designers should then be able to evaluate which of the options at hand provide that adequate level of availability.

Designing Networks with the Optimal Availability

A system for partitioning SONET frames into logical channels in a SONET ring is described. A SONET frame comprising a number of STS frames is subdivided into a plurality of logical channels. Each logical channel includes one or more STS frames. A protection layer is assigned to each logical channel. The protection layer may correspond to protection provided by the SONET ring or protection provided by network elements and specific to the type of data traffic transmitted within each channel. If SONET level protection for a particular logical channel is disabled, the bandwidth for the STS frames comprising that channel may be allocated among two or more nodes in the SONET ring.
