摘要： A method, a network, and a network element use dynamic packet traffic performance adjustment techniques. In an exemplary embodiment, the dynamic resizing techniques utilize different packet connections providing connectivity to same sites between which bandwidth resizing is needed. Each of the packet connections has a separate and independent bandwidth profile that governs an amount of traffic that is dispatched over each packet connection. A network element sourcing traffic into the packet connections uses bridge functionality that dispatches client traffic onto all of the packet connections or an individual packet connection. This effectively means that the transport network bandwidth utilization is only consumed by a single packet connection, i.e., the packet connection-A (even through there are multiple configured). The network element sinking the traffic selects from a single active packet connection.

摘要： A method and system provide in-band protection switch signaling in a communication system arranged as a point-to-multipoint tree. The point-to-multipoint tree includes a root node communicatively coupled to a plurality of leaf nodes through both a working link and a protection link. Data is transferred through a current link of the point-to-multipoint tree. The current link is either the working link or the protection link. A fault is detected in the current link in the point-to-multipoint tree. Each leaf node in the point-to-multipoint tree is notified of the fault using the current link. Upon receiving the notification, the root node and each leaf node switch to the other link of the working link and the protection link.

摘要： A configuration for a SONET transport node comprises a pair of transparent mux/demuxs provided at two sites and connected over a high rate span. The T-Muxs provide continuity of all tribs and maintain a lower bit rate linear or ring system through the higher bit rate span. The lower bit rate linear or ring system operates as if it were directly connected without the higher bit rate midsection. For the forward direction of the traffic, the T-Mux comprises a multi-channel receiver for receiving the trib signals and providing for each trib signal a trib SPE and a trib OH. The trib SPEs are multiplexed into a supercarrier SPE and the trib OHs signals are processed to generate a supercarrier OH. A supercarrier transmitter maps the supercarrier SPE and the supercarrier OH into a supercarrier signal and transmits same over the high rate span. Reverse operations are effected for the reverse direction of traffic. With this invention, an entire ring system does not have to be upgraded to a higher line rate due to fiber exhaust on a single span. The invention is particularly applicable to OC-48/OC-12/OC-3 linear and ring networks and the high rate span could be an OC-192 line.

摘要： A new architectural arrangement for network elements deployed in a central office (CO) is disclosed. The architectural arrangement involves dividing the network elements into an optical layer comprised of elements that have optical signal interfaces and switch optical signals, an opto-electrical layer comprised of elements that have optical signal interfaces and switch electrical signals, and an electrical layer comprised of elements that have electrical signal interfaces and switch electrical signals. The opto-electrical layer connects the optical and the electrical layer, and also connects lower-rate optical links into the CO. This layered architectural arrangement allows for more efficient use to be made of the small number of high-rate ports supported in the optical layer, and for the off loading of switching responsibility from both the optical and the electrical layers. This, in turn, improves the overall performance and capacity of the CO. The opto-electrical layer can be implemented using known transport nodes that are only slightly modified for deployment within the CO environment.

摘要： The virtually unused switching fabric of an OC-192 SONET transport node is used to greater effect when used as a switching node. Several of the nodes are used in the central office (CO) of a communication network. Each node terminates an optical network link and each node hosts a number of transport cards that also terminate different optical network links. The nodes provide space-switching between the cards. Additionally an intra-CO optical link is provided that interconnects the nodes to allow traffic flow between any of the optical network links in the CO that are terminated by transport cards or the nodes.

摘要： The invention provides for a method for transporting a SONET formatted asynchronous transfer mode (ATM) signal and/or a synchronous transfer mode (STM) signal on a line switched ring over a unidirectional path. The SONET formatted ATM signal comprises cells mapped into a STS-Mc or m×STS-1s while the STM signal comprises STS-1s/VTS mapped STS-W. A unidirectional line switched ring is provided for transporting the STM STS-W using a unidirectional path switched protection protocol and the ATM STS-Mc using a unidirectional line switched protection protocol. A ring node comprises input and output ring interfaces, an STS management block, an ATM cell management block, and a non-ATM payload management block. The STS management block routes the traffic to the ATM cell management block and to the non-ATM payload management block, according to the traffic type. The STS management block also provides the UPSR protection for the STS-1s and ULSR protection for the STS-Mc. The ATM cell management block maps the add ATM cells received from the ATM ports into the STS-Mc signal, and delineates the cells from the STS-Mc to present them to the ATM ports. The non-ATM payload management block routes STM VTs or STS-1s to/from the non-ATM ports.
