摘要： A method for rate-based flow control protocol on a ring topology network utilizing ethernet packet format and ethernet equipment. The method operates on a communication network communicatively coupling a plurality of network nodes each representing a local area network (LAN). The method for controlling a transmission of a data packets on the ring-topology communication network uses the following steps. A flow path is determined for data packets in the communication network. In another step, limits are calculated for the flow paths of the data packets with respect to each of the network nodes such that the data packets have controlled access to transmit on the communication network. In a final step, the transmission of the data packets on the flow paths is controlled according to the limits and using a packet format and equipment that is directly compatible with the local area network.

摘要： A broadband service control point provides processing instructions and data to a broadband session controller and an information sender/receiver. The broadband session controller communicates with a user's settop controller and video information providers, ("VIPs"), and requests processing information from the broadband service control point in response to predetermined triggers. The broadband session controller also instructs the broadband switch network to establish broadband connections between a VIP and a predetermined settop controller. An integrated service control point integrates broadband and telephone networks to provide efficient and effective integrated broadband and telephone services via video interface at a user's remote location. Also, the integrated network provides unique caller identification delivery services.

摘要： Optical networks, network elements, and methods of use are described herein, including an optical network comprising head-end and tail-end network elements, an optical multiplex section (OMS) connecting the head-end and tail-end network elements, and one or more intermediate line amplifiers in the OMS between the head-end and tail-end network elements. The head-end network element may store first information indicative of a first tilt control section having the head-end and tail-end network elements as endpoints; determine information indicative of a change in topology of the OMS, such as that a first intermediate line amplifier has switched from a non-monitoring to a monitoring mode; and store second information indicative of a second tilt control section having the head-end network element and a new tail-end network element, such as the first intermediate line amplifier.
