text: In conventional large-scale networks, creation and management of network services
are costly and complex tasks that often consume a lot of resources, including
time and manpower. Network softwarization and network function virtualization
have been introduced to tackle these problems, aiming at decreasing costs and
complexity of implementing new services, maintaining the implemented services,
and managing available resources in service provisioning platforms and underlying
infrastructures. To experience the full potential of these approaches, innovative
development support tools and service provisioning environments are needed. To
answer these needs, we introduce the architecture of the open-source SONATA system,
a service programming, orchestration, and management framework. We present a development
toolchain for virtualized network services, fully integrated with a service platform
and orchestration system. We introduce the modular and flexible architecture of
our system and discuss its main components and features, such as function- and
service-specific managers that allow fine-grained service management, slicing
support to facilitate multi-tenancy, recursiveness for improved scalability, and
full-featured DevOps support.

text: "Developing a virtualized network service does not only involve the\r\n implementation
and configuration of the network functions it is\r\n composed of but also its
integration and test with management\r\n solutions that will control the service
in its production\r\n environment. These integration tasks require testbeds that
offer the\r\n needed network function virtualization infrastructure~(NFVI), like
OpenStack, introducing a\r\n lot of management and maintenance overheads. Such
testbed setups\r\n become even more complicated when the multi\r\n point-of-presence~(PoP)
case, with multiple infrastructure\r\n installations, is considered.\r\n\r\n
\ In this demo, we showcase an emulation platform that executes\r\n containerized
network services in user-defined multi-PoP\r\n topologies. The platform does
not only allow network service developers to\r\n locally test their services
but also to connect real-world\r\n management and orchestration solutions to
the emulated PoPs. During our\r\n interactive demonstration we focus on the integration
between\r\n the emulated infrastructure and state-of-the-art orchestration\r\n
\ solutions like SONATA or OSM."

text: Management of complex network services requires flexible and efficient service
provisioning as well as optimized handling of continuous changes in the workload
of the service.To adapt to changes in the demand, service components need to be
replicated (scaling) and allocated to physical resources (placement) dynamically.
In this paper, we propose a fullyautomated approach to the joint optimization
problem of scaling and placement, enabling quick reaction to changes. We formalize
the problem, analyze its complexity, and develop two algorithms to solve it. Extensive
empirical results show the applicability andeffectiveness of the proposed approach.

text: "Benchmarking and profiling virtual network functions (VNFs) generates input\r\nknowledge
for resource management decisions taken by \r\nmanagement and orchestration systems.
\r\nSuch VNFs are usually not executed in isolation but are often deployed as
part of a service function chain (SFC) that connects single functions into complex
\r\nstructures. To manage such chains, isolated performance\r\nprofiles of single
functions have to be combined to get insights into \r\nthe overall behavior of
an SFC. This becomes particularly\r\nchallenging in highly agile DevOps environments
in which profiling\r\nprocesses need to be fully automated and detailed insights
about a chain's\r\ninternal structures are not always available. \r\n\r\nIn this
paper, we introduce a\r\nfully automatable, flexible, and platform-agnostic profiling\r\nsystem
that allows to profile entire SFCs at once. This obviates \r\nmanual modeling
procedures to combine profiling results from single\r\nVNFs to reflect SFC performance.
\r\nWe use a case study with different SFC configurations to show that it\r\nis
hard to model the resulting SFC performance based on single-VNF measurements and
that\r\nperformance interactions between real, non-trivial functions that are
deployed in a\r\nchain exist. "

text: The Service Programming and Orchestration for Virtualised Software Networks
(SONATA) project targets both the flexible programmability of software networks
and the optimisation of their deployments by means of integrating Development
and Operations in order to accelerate industry adoption of software networks and
reduce time-to-market for networked services. SONATA supports network function
chaining and orchestration, making service platforms modular and easier to customise
to the needs of different service providers, and introduces a specialised Development
and Operations model for supporting developers.

text: "Allocating resources to virtualized network functions and services to meet
service level agreements is a challenging task for NFV management and orchestration
systems. This becomes even more challenging when agile development methodologies,
like DevOps, are applied. In such scenarios, management and orchestration systems
are continuously facing new versions of functions and services which makes it
hard to decide how much resources have to be allocated to them to provide the
expected service performance. \r\nOne solution for this problem is to support
resource allocation decisions with performance behavior information obtained by
profiling techniques applied to such network functions and services.\r\n\r\nIn
this position paper, we analyze and discuss the components needed to generate
such performance behavior information within the NFV DevOps workflow. We also
outline research questions that identify open issues and missing pieces for a
fully integrated NFV profiling solution. Further, we introduce a novel profiling
mechanism that is able to profile virtualized network functions and entire network
service chains under different resource constraints before they are deployed on
production infrastructure."

text: "Traditional cellular networks are forced to remain active regardless of the
actual amount of traffic that is currently produced/requested, with a clear waste
of energy. Two-layer mobile networks with separated signalling and data layers
have been recently proposed for energy savings in future implementations. These
networks are able to switch off unneeded data cells completely while maintaining
full coverage with their signalling cells, thus saving energy. In this demonstration,
we showcase a testbed that uses Wi-Fi access points to emulate small cells of
the data layer and a publicly available cellular connection as the signalling
layer. We use off-the-shelf Android smartphones with an ad-hoc networking management
module and a MultiPath TCP-enabled kernel to manage the Wi-Fi and cellular interfaces
simultaneously.\r\nThe testbed is used to demonstrate the general feasibility
of this layered architecture and to facilitate experiments with network-wide resource
optimization. "

text: "Elastic deployments of virtualized network functions~(VNF) can automatically
scale the amount of used resources in relation to their workload. This is often
done by starting new VNF instances or stopping old ones. A problem of these scale
operations is that most network functions are stateful and their internal state
is not automatically migrated when traffic is redistributed in the deployment.
As a result, mechanisms are needed to exchange or migrate internal network function
state between VNF instances.\r\n\r\nThis paper presents a state management framework
that creates a logically distributed state store on top of elastically deployed
virtual network functions. We also introduce a novel programming model that provides
both a local and a global view of the state to each VNF instance. We discuss the
integration of our framework into existing network function virtualization architectures
and compare the performance of our prototype to a centralized and a distributed
state store solution."

text: "Virtualized network services consisting of multiple individual network functions
are already today deployed across multiple sites, so called multi-PoP (points
of presence) environments. This allows to improve service performance by optimizing
its placement in the network. But prototyping and testing of these complex distributed
software systems becomes extremely challenging. The reason is that not only the
network service as such has to be tested but also its integration with management
and orchestration systems. Existing solutions, like simulators, basic network
emulators, or local cloud testbeds, do not support all aspects of these tasks.\r\n\r\nTo
this end, we introduce MeDICINE, a novel NFV prototyping platform that is able
to execute production-ready network functions, provided as software containers,
in an emulated multi-PoP environment. These network functions can be controlled
by any third-party management and orchestration system that connects to our platform
through standard interfaces. Based on this, a developer can use our platform to
prototype and test complex network services in a realistic environment running
on his laptop.\r\n"

text: Network function virtualization and software-defined networking allow services
consisting of virtual network functions to be designed and implemented with great
flexibility by facilitating automatic deployments, migrations, and reconfigurations
for services and their components. For extended flexibility, we go beyond seeing
services as a fixed chain of functions. We present a YANG model for describing
the service structure in deployment requests in a flexible way that enables changing
the order of functions in case the order of traversing them does not affect the
functionality of the service. Upon receiving such requests, the network orchestration
system can choose the optimal composition of service components that gives the
best results for placement of services in the network. This introduces new complexities
to the placement problem by greatly increasing the number of possible ways a service
can be composed. In this paper, we describe a heuristic solution that selects
a Pareto set of the possible compositions of a service as well as possible combinations
of different services, with respect to different resource requirements of the
services. Our evaluations show that the selected combinations consist of representative
samples of possible structures and requirements and therefore, can result in optimal
or close-to-optimal placement results.

text: 'Video streaming is in high demand by mobile users. In cellular networks,
however, the unreliable wireless channel leads to two major problems. Poor channel
states degrade video quality and interrupt the playback when a user cannot sufficiently
fill its local playout buffer: buffer underruns occur. In contrast, good channel
conditions cause common greedy buffering schemes to buffer too much data. Such
over-buffering wastes expensive wireless channel capacity. Assuming that we can
anticipate future data rates, we plan the quality and download time of video segments
ahead. This anticipatory download scheduling avoids buffer underruns by downloading
a large number of segments before a drop in available data rate occurs, without
wasting wireless capacity by excessive buffering.We developed a practical anticipatory
scheduling algorithm for segmented video streaming protocols (e.g., HLS or MPEG
DASH). Simulation results and testbed measurements show that our solution essentially
eliminates playback interruptions without significantly decreasing video quality.'

text: The size of modern data centers is constantly increasing. As it is not economic
to interconnect all machines in the data center using a full-bisection-bandwidth
network, techniques have to be developed to increase the efficiency of data-center
networks. The Software-Defined Network paradigm opened the door for centralized
traffic engineering (TE) in such environments. Up to now, there were already a
number of TE proposals for SDN-controlled data centers that all work very well.
However, these techniques either use a high amount of flow table entries or a
high flow installation rate that overwhelms available switching hardware, or they
require custom or very expensive end-of-line equipment to be usable in practice.
We present HybridTE, a TE technique that uses (uncertain) information about large
flows. Using this extra information, our technique has very low hardware requirements
while maintaining better performance than existing TE techniques. This enables
us to build very low-cost, high performance data-center networks.

text: 'Multi-rooted trees are becoming the norm for modern data-center networks.
In these networks, scalable flow routing is challenging owing to vast number of
flows. Current approaches either employ a central controller that can have scalability
issues or a scalable decentralized algorithm only considering local information.
In this paper we present a new decentralized approach to least-congested path
routing in software-defined data center networks that has neither of these issues:
By duplicating the initial (or SYN) packet of a flow and estimating the data rate
of multiple flows in parallel, we exploit TCP’s habit to fill buffers to find
the least congested path. We show that our algorithm significantly improves flow
completion time without the need for a central controller or specialized hardware.'
