Abstract: The invention relates to a method and system for providing a unified user interface to a communication network, comprising means for generating the user interface based on user mode (2), and means for converting the user mode to a presentation mode (3) using a list (4) of attributes for presentation. The user interface (1) is generated additionally taking account of the connectivity level. Selection means for selecting the user mode by a user, and detection means for automatically detecting available connectivity levels at the current environment may be provided.

Abstract: Interworking of optical protection in an optical network and IP-layer protection in the Internet is achieved by configuring optical links to form a part of a ring network and by arranging different protection types for different links. Each optical link is provided with an appropriate protection level corresponding to the nature of Internet traffic being transmitted over the link. The highest protection level is achieved with 1+1 protection. The optical layer can offer this protection for high priority Internet traffic that does not tolerate delay. The middle and the low protection level are achieved with 1:1 protection. The low protection level of a link does not guarantee uninterrupted transmission of the Internet traffic, in case of link failure caused by a fiber cut. Optical signaling at the optical layer takes care of protection wherein the IP-layer does not know when protection actions are carried out.
