In this paper, we investigate the problem of survivable all-optical routing in WDM networks
with physical impairments. One of the recent key issues in survivable optical network design …

Need for efficient and reliable network transport technologies has led to the introduction of
all optical networks and routing technologies. With the spreading of new, bandwidth …

The majority of papers on resilience deal with fast and resource-saving mechanisms that are
typically taylored to a certain networking technology or to a certain protocol. The aim of this …

The difference between dedicated and shared protection is well known. In this paper we
investigate these ideas applied to sharing power budgets of links. When defining protection …

In this paper we present the idea to use the grooming-capability of two-layer networks not
only to better handle traffic, but also to implicitly regenerate physically impaired optical …

The amount of traffic transported over the Internet is growing year by year. According to the
latest forecast this trend will not be changed in the near future. As the end users have gotten …

In optical networks, according to the latest tendencies, the goal is to route all demands in all-
optical way. However, in the near future, this will still not be possible due to technical …
