Abstract: The present invention provides a fiber deployment method, storage medium, electronic device and system. The fiber deployment method includes the following steps: S10, traversing all single-mode fiber links and selecting a link for ultra-low loss fiber upgrade with the objective of minimizing the maximum number of frequency slots used in the whole network; and S20, when both an ultra-low loss fiber and a single-mode fiber satisfy the service demand, using preferentially spectrum resources in the single-mode fiber.

Abstract: A method, system and computer program product for integrating a calendaring system with a mashup page. A mashup server accesses the calendar data inputted by a user to create or edit an entry in a calendar application. The mashup server provides the user access to widgets to be included on a mashup page, where the widgets use the accessed calendar information so that the widgets provide information to the recipients of the calendared event. In this manner, the widgets provide information that normally would be accessible by the participants via links to a myriad of disjoint applications thereby negating the fractured experience of the participants. Upon finalizing the mashup page, the mashup page is saved as a Uniform Resource Location (URL) in the created/edited calendar entry. The mashup page is later transmitted by the mashup server to the recipients of the calendar entry.
