With the development of 5G technology, high definition video and internet of things, the
capacity demand for optical networks has been increasing dramatically. To fulfill the capacity …

Network function virtualization (NFV) is a promising technology to decouple the network
functions from dedicated hardware elements, leading to the significant cost reduction in …

Modern network services are constantly increasing their requirements in terms of bandwidth,
latency and cost efficiency. To satisfy these requirements, the concept of network slicing has …

This paper studies the problem of service chain (SC) deployment. Specifically, we try to
place virtual network functions (vNFs) on network nodes and connect the vNFs in sequence …

We study how to allocate spectrum and IT resources jointly for realizing efficient virtual
network function (VNF) service chaining in inter-datacenter elastic optical networks. We first …

It is known that by leveraging programmable data plane, in-band network telemetry (INT)
can be realized to provide a powerful and promising method to collect realtime network …

It is known that by incorporating network function virtualization (NFV) in inter-datacenter
(inter-DC) networks, service providers can use their network resources more efficiently and …

This work addresses the relatively long setup latency and complicated network control and
management caused by on-demand virtual network function service chain (vNF-SC) …

Network function virtualization (NFV) in elastic optical datacenter interconnections (EO-
DCIs) enables flexible and timely deployment of network services. However, as the service …

With the boom of Internet of Things (IoT), an increasing amount of data from IoT applications
is moved to geo-distributed data centers (DCs) for data analysis. Massive compute …
