This special issue was well received, and the guest editors
received more than 18 high-quality technical papers. All sub-
mitted papers were peer-reviewed by experienced reviewers.
After a thorough review process and based on comments
received from the reviewers, 7 papers have been selected for
publication in this Special Issue of the Springer Photonic
Network Communications (PNET) journal.
We are pleased to introduce a collection of 7 papers (accep-
tance ratio of 38.9 %) covering a range of hot topics in cloud
optical networks such as elastic cloud optical networks, cloud
optical data center networks, cloud optical access networks.
A brief summary of accepted papers is provided next.
In “Design of optical ﬁlters and switches used in telecom-
munications and computer engineering; S. Eslamian, A.
Mazaheri, M. H. Keshavarz, S. Omidvari, E. Goodarzi, and
M. Honarjou”, the authors investigate optical switch, optical
ﬁlter and attenuator intensity system based on photonic crys-
tal structure in communication and computer applications
for cloud optical networks. Simulation is obtained by using
ﬁnite element method and ﬁnite-difference time-domain
In “Adaptive multilevel modulation for grooming in elas-
tic cloud optical networks; C. Yu, W. Hou, Y. Wu, J. Wu and
Z. Sun”, the authors propose green grooming for elastic cloud
optical networks based on link adaption. This position paper
demonstrates the important role of adaptive multilevel mod-

ulation on saving spectrum and power consumption for the
green grooming in elastic cloud optical networks, because the
spectral bandwidth can be saved by increasing the number
of bits per symbol to transmit the same data rate.
In “Survivable routing, spectrum and waveband assign-
ment strategy in cloud optical and data center network; S.
Yin, S. Huang, Y. Zhou, H. Huang, J. Zhang and W. Gu”, the
authors study the survivable routing, spectrum and waveband
assignment strategy in cloud optical data center networks,
and a novel algorithm named HSPGA is presented to signif-
icantly decrease the amount of employed ports, along with
the improved spectrum efﬁciency.
In “Availability-aware service provisioning in SD-EON-
based inter-datacenter networks; X. Chen, F. Ji, S. Zhu, Q.
Bao, and Z. Zhu”, the authors experimentally access the per-
formance of a novel availability-aware service provisioning
solution in software deﬁned elastic cloud optical data cen-
ter networks. This solution is assorted with the algorithm
that leverages different path protection schemes and service
downgrading strategy to satisfy different service availability
requirements and further improve the system performance.
In “Novel multi-band DFT-spread OFDM-PON systems
based on intensity modulation and direct detection for cloud
computing; X. Gong, Y. Peng, Y. Liu and H Li”, the authors
propose a transmission system approach tailored to cloud
optical access networks, in terms of the OFDM-PON based
on intensity modulation and direct detection. The DFT-
spread is utilized to reduce the peak-to-average power ratio
(PAPR), and meanwhile, a multi-band power allocation and
bit loading are achieved to satisfy the different degrees of
QoS requirement owned by ONUs.
In “Survivable deployment of cloud-integrated ﬁber-
wireless networks against multi-ﬁber failure; Y. Yu, Y. Liu,
P. Han, and Y. Zhou”, the authors investigate the optimiza-
tion of tolerating multiple disabled distribution ﬁbers with
