摘要： The present invention provides a broadband service nesting processing method and device, and a service application server. The method includes: receiving a service request message sent to a user equipment, and obtaining a service identity of a current service carried in the service request message; determining that service nesting is formed between a terminating call service and a service corresponding to the service identity of the current service; and evading the terminating call service according to a result of the service nesting formed between the terminating call service and the service corresponding to the service identity. A technical solution provided in an embodiment of the present invention can effectively avoid the occurrence of service nesting phenomena.

摘要： The embodiments of the present invention provide a tunnel fault detection method and a traffic engineering (TE) node. The method includes: receiving, by a traffic engineering TE node, a link fault report packet; determining, by the node, a faulty link in which a fault occurs according to the link fault report packet; detecting, by the node, whether one or more tunnels which use the node as an ingress node and pass through the faulty link exist; and identifying the tunnels as faulty tunnels if the one or more tunnels which use the node as the ingress node and pass through the faulty link exist. In the embodiments of the present invention, the TE node can detect all faulty tunnels at a time, and it is not necessary to wait until the fault notification based on each tunnel is received and then the faulty tunnel is identified one by one.

摘要： Example fiber amplifiers and gain adjustment methods for the fiber amplifiers are described. One example fiber amplifier includes a first power amplifier, a wavelength level adjuster, and a controller, where the first power amplifier is connected to the wavelength level adjuster. The controller includes a first input end and a control output end. The first input end is configured to receive an input optical signal, and the control output end is configured to output a first amplification control signal to the first power amplifier, and output an adjustment control signal to the wavelength level adjuster. The wavelength level adjuster is configured to perform power adjustment on each wavelength in a separate manner based on the adjustment control signal.

摘要： A method for determining an optical signal power change, wherein the method includes: A first optical signal that includes a plurality of wavelength signals is obtained, where the plurality of wavelength signals are distributed in a plurality of bands. Then, an optical power of each band and a center wavelength signal of each band are detected, and a preset single-wavelength transmit power and a preset coefficient are obtained. Next, an equivalent quantity N of equivalent wavelength signals is determined, and an equivalent wavelength signal corresponding to the first optical signal is determined. Further, a target power that is used to compensate for a first power change value of the first optical signal in transmission over an optical fiber is determined based on the preset coefficient, the equivalent wavelength signal, the equivalent quantity, and the preset single-wavelength transmit power.
