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 and orchestration~(MANO) systems are the key components of future
large-scale NFV environments. They will manage resources of hundreds or even thousands
of NFV infrastructure installations, so called points of presence~(PoP). Such
scenarios need to be automatically tested during the development phase of a MANO
system. This task becomes very challenging because large-scale NFV testbeds are
hard to maintain, too expensive, or simply not available.\r\n\r\nIn this paper,
we present a multi-PoP NFV infrastructure emulation platform that enables automated,
large-scale testing of MANO stacks. We show that our platform can easily emulate
hundreds of PoPs on a single physical machine and reduces the setup time of a
test PoP by a factor of 232x compared to a DevStack-based test PoP installation.
Further, we present a case study in which we test ETSI's Open Source MANO~(OSM)
against our proposed system to gain insights about OSM's behaviour in large-scale
NFV deployments."

text: To adapt to continuously changing workloads in networks, components of the
running network services may need to be replicated (scaling the network service)
and allocated to physical resources (placement) dynamically, also necessitating
dynamic re-routing of flows between service components. In this paper, we propose
JASPER, a fully automated approach to jointly optimizing scaling, placement, and
routing for complex network services, consisting of multiple (virtualized) components.
JASPER handles multiple network services that share the same substrate network;
services can be dynamically added or removed and dynamic workload changes are
handled. Our approach lets service designers specify their services on a high
level of abstraction using service templates. JASPER automatically makes scaling,
placement and routing decisions, 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 and effectiveness of the proposed approach.

text: "Dynamic allocation of resources is a key feature in network function virtualization
(NFV), enabling flexible adjustment of slices and contained network services to
ever-changing service demands. \r\nConsidering resource allocation across the
entire network, many authors have proposed approaches to optimize the placement
and chaining of virtual network function (VNF) instances and the allocation of
resources to these VNF instances. In doing so, various optimization objectives
are conceivable, e.g., minimizing certain required resources or the end-to-end
delay of the placed services.\r\n\r\nIn this paper, we investigate the relationship
between four typical optimization objectives when coordinating the placement and
resource allocation of chained VNF instances. We observe an interesting trade-off
between minimizing the overhead of starting/stopping VNF instances and all other
objectives when adapting to changed service demands."

text: "In recent years, a variety of different approaches\r\nhave been proposed
to tackle the problem of scaling and placing\r\nnetwork services, consisting of
interconnected virtual network\r\nfunctions (VNFs). This paper presents a placement
abstraction\r\nlayer (PAL) that provides a clear and simple northbound interface\r\nfor
using such algorithms while hiding their internal\r\nfunctionality and implementation.
Through its southbound interface,\r\nPAL can connect to different back ends that
evaluate\r\nthe calculated placements, e.g., using simulations, emulations, or\r\ntestbed
approaches. As an example for such evaluation back ends,\r\nwe introduce a novel
placement emulation framework (PEF)\r\nthat allows executing calculated placements
using real, containerbased\r\nVNFs on real-world network topologies. In a case
study,\r\nwe show how PAL and PEF facilitate reusing and evaluating\r\nplacement
algorithms as well as validating their underlying\r\nmodels and performance claims."

text: "A key challenge of network function virtualization\r\n(NFV) is the complexity
of developing and deploying new\r\nnetwork services. Currently, development requires
many manual\r\nsteps that are time-consuming and error-prone (e.g., for creating\r\nservice
descriptors). Furthermore, existing management and\r\norchestration (MANO) platforms
only offer limited support of\r\nstandardized descriptor models or package formats,
limiting the\r\nre-usability of network services.\r\n\r\nTo this end, we introduce
a fully integrated, open-source\r\nNFV service development kit (SDK) with multi-MANO
platform\r\nsupport. Our SDK simplifies many NFV service development\r\nsteps
by offering initial generation of descriptors, advanced\r\nproject management,
as well as fully automated packaging and\r\nsubmission for on-boarding. To achieve
multi-platform support,\r\nwe present a package format that extends ETSI’s VNF
package\r\nformat. In this demonstration, we present the end-to-end workflow\r\nto
develop an NFV service that is then packaged for multiple\r\nplatforms, i.e.,
5GTANGO and OSM."

text: "Signal processing in WASNs is based on a software framework for hosting the
algorithms as well as on a set of wireless connected devices representing the
hardware. Each of the nodes contributes memory, processing power, communication
bandwidth and some sensor information for the tasks to be solved on the network.
\r\nIn this paper we present our MARVELO framework for distributed signal processing.
It is intended for transforming existing centralized implementations into distributed
versions. To this end, the software only needs a block-oriented implementation,
which MARVELO picks-up and distributes on the network. Additionally, our sensor
node hardware and the audio interfaces responsible for multi-channel recordings
are presented."

text: The microservice architecture uses independently running microservices as
build- ing blocks for applications. These microservices are clearly bounded for
each other and expose their functionality through, for instance, RESTful application
inter- faces. Particularly the clear boundaries between microservices enable the
reuse of microservice throughout different projects. Because of the increasing
use of microservices, the composition of multiple microservices in service composition
becomes a more important task. A challenging area in developing service compo-
sitions is that it involves two distinct layers with few junctions. On the one
hand, describes a service composition a business process, which involves multiple
com- ponents. On the other hand, involves the implementation of a service composition
topics like service discovery and message exchange protocols since the microser-
vices involved in a service composition are located within a network environment.
In this Bachelor’s Thesis, I describe a descriptions language to abstractly describe
the business logic of a service composition. Furthermore, I describe a genera-
tion process, which compiles this abstract description to a working microservice
realizing the specified service composition. In addition to that, I provide an
im- plementation of the generation process, as a proof of concept, and test it
within a Kubernetes-based cluster environment.

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 define the service structure in a flexible
way that enables changing the order of functions in case the functionality of
the service is not influenced by this, and propose a YANG data model for expressing
this flexibility. Flexible structures allow the network orchestration system to
choose the optimal composition of service components that for example gives the
best results for placement of services in the network. When number of flexible
services and number of components in each service increase, combinatorial explosion
limits the practical use of this flexibility. In this paper, we describe a selection
heuristic that gives a Pareto set of the possible compositions of a service as
well as possible combinations of different services, with respect to different
optimization objectives. Moreover, we present a heuristic algorithm for placement
of a combination of services, which aims at placing service components along shortest
paths that have enough capacity for accommodating the services. By applying these
solutions, we show that allowing flexibility in the service structure is feasible.

text: 'A current trend in networking and cloud computing is to provide compute resources
at widely distributed sites; this is exemplified by developments such as Network
Function Virtualisation. This paves the way for wide-area service deployments
with improved service quality: e.g. user-perceived response times can be reduced
by offering services at nearby sites. But always assigning users to the nearest
site can be a bad decision if this site is already highly utilised. This paper
formalises two related decisions of allocating compute resources at different
sites and assigning users to them with the goal of minimising the response times
while the total number of resources to be allocated is limited – a non-linear
capacitated Facility Location Problem with integrated queuing systems. To efficiently
handle its non-linearity, we introduce five linear problem linearisations and
adapt the currently best heuristic for a similar scenario to our scenario. All
six approaches are compared in experiments for solution quality and solving time.
Surprisingly, our best optimisation formulation outperforms the heuristic in both
time and quality. Additionally, we evaluate the influence of distributions of
available compute resources in the network on the response time: The time was
halved for some configurations. The presented formulation techniques for our problem
linearisations are applicable to a broader optimisation domain.'

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. "
