In this paper, the problem of routing, modulation level, core, and spectrum assignment
(RMCSA) in space-division-multiplexed elastic optical networks (SDM-EONs) is studied. We …

As elastic optical networks (EONs) are expected to convey high bitrate connections, a failure
in these networks causes vast data losses. Thus, addressing the problem of survivability in …

For addressing the problems of high bandwidth blocking probability and low spectrum
utilization caused by spectrum fragmentation in elastic optical networks (EONs), a dynamic …

The space division multiplexing elastic optical network (SDM-EONs) can effectively supply
the large-capacity for the current optical network. If a link failure occurs, it will bring huge …

One of the visions of fifth-generation fixed networks (F5G) is to provide a guaranteed reliable
experience (GRE). Optical transport networks (OTNs) represent a primary candidate …

Optical networks can support service degradation by providing bandwidth lower than that
required to adapt the network provisioning when optical resources are insufficient. This …

A fragmentation-avoiding spectrum assignment strategy based on spectrum partition is
proposed, which is used to resolve the spectrum fragmentation problem in elastic optical …

Abstract Space division multiplexing elastic optical networks (SDM-EONs) are considered as
a efficient solution for increasing the link's capacity. However, the SDM-EONs brought …

Fixed alternate routing is a potential routing scheme for routing and spectrum allocation
(RSA) in elastic optical networks (EON) which has less complexity and time consumption …

Network virtualization can enhance the flexibility of Internet infrastructure resources and the
scalability of the substrate elastic optical networks (EONs) through the coexistence of …
