A method and apparatus facilitates an enterprise to lease virtual appliances from network services provider. The method operates by deploying a converged networking and computing device at a service location, downloading a virtual network function to the converged networking and computing device, activating the virtual network function by a service in the wide area network, and connecting the virtual network function to a provisioned network path over the wide area network. Different virtual network functions can be deployed to different locations. The same virtual network function scan be deployed to different locations. Moreover, more than one virtual network function may be deployed to more than one service location. The virtual network functions can be realized through virtual machines, software containers, etc.

A method and apparatus for adjusting power in an optical signal are disclosed and a bidirectional equalized amplifier for providing bidirectional equalization, employing the apparatus and method is disclosed. Use of the method and apparatus to form a seamless ring in an optical network is also disclosed. The method of adjusting power involves splitting an input composite signal into respective drop signals in separate wavelength bands and respective pass signals with a splitter. An attenuator attenuates the drop signals to produce attenuated drop signals. A combiner combines the attenuated drop signals to produce a first output composite signal in which the power is equalized.
