A communication network is configured to implement time scale separated management and provisioning optimizations, for example, in a core optical network coupled to multiple data networks. Network management optimizations are performed at respective points in time separated by intervals of a first time scale, and network provisioning optimizations are performed at respective points in time separated by intervals of a second time scale, with the intervals of the second time scale being on average substantially longer than the intervals of the first time scale. Moreover, at least a given one of the intervals of the second time scale has a length which is determined based on results of performance of one or more of the network management optimizations. The core optical network maybe configured utilizing information specified by the network management and network provisioning optimizations.

A hand-held combination key apparatus configured to input information to an intelligent electronic apparatus is provided. Three to five key groups, which correspond to each corresponding finger of a single hand respectively, are set on one of left side and right side of a shell, each key group having two combination keys, and each combination key being the key with compound functions of touch conduction and press conduction. Various combination states of touch conduction of each combination key are used to search and pre-display characters or operational function symbols; and press conduction of each combination key is used to determine character input or operational function input. The hand-held combination key apparatus can be used in any state without limitation absolutely, such as when the user is sitting, standing, lying down and moving, other than the normal standard keyboard which needs a practicable plane to support in use, saving space.
