text: "Modern services consist of modular, interconnected\r\ncomponents, e.g., microservices
forming a service mesh. To\r\ndynamically adjust to ever-changing service demands,
service\r\ncomponents have to be instantiated on nodes across the network.\r\nIncoming
flows requesting a service then need to be routed\r\nthrough the deployed instances
while considering node and link\r\ncapacities. Ultimately, the goal is to maximize
the successfully\r\nserved flows and Quality of Service (QoS) through online service\r\ncoordination.
Current approaches for service coordination are\r\nusually centralized, assuming
up-to-date global knowledge and\r\nmaking global decisions for all nodes in the
network. Such global\r\nknowledge and centralized decisions are not realistic
in practical\r\nlarge-scale networks.\r\n\r\nTo solve this problem, we propose
two algorithms for fully\r\ndistributed service coordination. The proposed algorithms
can be\r\nexecuted individually at each node in parallel and require only\r\nvery
limited global knowledge. We compare and evaluate both\r\nalgorithms with a state-of-the-art
centralized approach in extensive\r\nsimulations on a large-scale, real-world
network topology.\r\nOur results indicate that the two algorithms can compete
with\r\ncentralized approaches in terms of solution quality but require\r\nless
global knowledge and are magnitudes faster (more than\r\n100x)."

text: "Modern services comprise interconnected components,\r\ne.g., microservices
in a service mesh, that can scale and\r\nrun on multiple nodes across the network
on demand. To process\r\nincoming traffic, service components have to be instantiated
and\r\ntraffic assigned to these instances, taking capacities and changing\r\ndemands
into account. This challenge is usually solved with\r\ncustom approaches designed
by experts. While this typically\r\nworks well for the considered scenario, the
models often rely\r\non unrealistic assumptions or on knowledge that is not available\r\nin
practice (e.g., a priori knowledge).\r\n\r\nWe propose a novel deep reinforcement
learning approach that\r\nlearns how to best coordinate services and is geared
towards\r\nrealistic assumptions. It interacts with the network and relies on\r\navailable,
possibly delayed monitoring information. Rather than\r\ndefining a complex model
or an algorithm how to achieve an\r\nobjective, our model-free approach adapts
to various objectives\r\nand traffic patterns. An agent is trained offline without
expert\r\nknowledge and then applied online with minimal overhead. Compared\r\nto
a state-of-the-art heuristic, it significantly improves flow\r\nthroughput and
overall network utility on real-world network\r\ntopologies and traffic traces.
It also learns to optimize different\r\nobjectives, generalizes to scenarios with
unseen, stochastic traffic\r\npatterns, and scales to large real-world networks."

text: Data-parallel applications run on cluster of servers in a datacenter and their
communication triggers correlated resource demand on multiple links that can be
abstracted as coflow. They often desire predictable network performance, which
can be passed to network via coflow abstraction for application-aware network
scheduling. In this paper, we propose a heuristic and an optimization algorithm
for predictable network performance such that they guarantee coflows completion
within their deadlines. The algorithms also ensure high network utilization, i.e.,
it's work-conserving, and avoids starvation of coflows. We evaluate both algorithms
via trace-driven simulation and show that they admit 1.1x more coflows than the
Varys scheme while meeting their deadlines.

text: "Network function virtualization (NFV) proposes\r\nto replace physical middleboxes
with more flexible virtual\r\nnetwork functions (VNFs). To dynamically adjust
to everchanging\r\ntraffic demands, VNFs have to be instantiated and\r\ntheir
allocated resources have to be adjusted on demand.\r\nDeciding the amount of allocated
resources is non-trivial.\r\nExisting optimization approaches often assume fixed
resource\r\nrequirements for each VNF instance. However, this can easily\r\nlead
to either waste of resources or bad service quality if too\r\nmany or too few
resources are allocated.\r\n\r\nTo solve this problem, we train machine learning
models\r\non real VNF data, containing measurements of performance\r\nand resource
requirements. For each VNF, the trained models\r\ncan then accurately predict
the required resources to handle\r\na certain traffic load. We integrate these
machine learning\r\nmodels into an algorithm for joint VNF scaling and placement\r\nand
evaluate their impact on resulting VNF placements. Our\r\nevaluation based on
real-world data shows that using suitable\r\nmachine learning models effectively
avoids over- and underallocation\r\nof resources, leading to up to 12 times lower
resource\r\nconsumption and better service quality with up to 4.5 times\r\nlower
total delay than using standard fixed resource allocation."

text: Currently, the coexistence of multiple users and devices challenges the network's
ability to reliably connect them. This article proposes a novel communication
architecture that satisfies the requirements of fifth-generation (5G) mobile network
applications. In particular, this architecture extends and combines ultra-dense
networking (UDN), multi-access edge computing (MEC), and virtual infrastructure
manager (VIM) concepts to provide a flexible network of moving radio access (RA)
nodes, flying or moving to areas where users and devices struggle for connectivity
and data rate. Furthermore, advances in radio communications and non-orthogonal
multiple access (NOMA), virtualization technologies and energy-awareness mechanisms
are integrated towards a mobile UDN that not only allows RA nodes to follow the
user but also enables the virtualized network functions (VNFs) to adapt to user
mobility by migrating from one node to another. Performance evaluation shows that
the underlying network improves connectivity of users and devices through the
flexible deployment of moving RA nodes and the use of NOMA.

text: 'Assigning bands of the wireless spectrum as resources to users is a common
problem in wireless networks. Typically, frequency bands were assumed to be available
in a stable manner. Nevertheless, in recent scenarios where wireless networks
may be deployed in unknown environments, spectrum competition is considered, making
it uncertain whether a frequency band is available at all or at what quality.
To fully exploit such resources with uncertain availability, the multi-armed bandit
(MAB) method, a representative online learning technique, has been applied to
design spectrum scheduling algorithms. This article surveys such proposals. We
describe the following three aspects: how to model spectrum scheduling problems
within the MAB framework, what the main thread is following which prevalent algorithms
are designed, and how to evaluate algorithm performance and complexity. We also
give some promising directions for future research in related fields.'

text: "Softwarization facilitates the introduction of smart\r\nmanufacturing applications
in the industry. Manifold devices\r\nsuch as machine computers, Industrial IoT
devices, tablets,\r\nsmartphones and smart glasses are integrated into factory
networks\r\nto enable shop floor digitalization and big data analysis. To\r\nhandle
the increasing number of devices and the resulting traffic,\r\na flexible and
scalable factory network is necessary which can be\r\nrealized using softwarization
technologies like Network Function\r\nVirtualization (NFV). However, the security
risks increase with\r\nthe increasing number of new devices, so that cyber security
must\r\nalso be considered in NFV-based networks.\r\n\r\nTherefore, extending
our previous work, we showcase threat\r\ndetection using a cloud-native NFV-driven
intrusion detection\r\nsystem (IDS) that is integrated in our industrial-specific
network\r\nservices. As a result of the threat detection, the affected network\r\nservice
is put into quarantine via automatic network reconfiguration.\r\nWe use the 5GTANGO
service platform to deploy our\r\ndeveloped network services on Kubernetes and
to initiate the\r\nnetwork reconfiguration."

text: "For optimal placement and orchestration of network services, it is crucial\r\nthat
their structure and semantics are specified clearly and comprehensively\r\nand
are available to an orchestrator. Existing specification approaches are\r\neither
ambiguous or miss important aspects regarding the behavior of virtual\r\nnetwork
functions (VNFs) forming a service. We propose to formally and\r\nunambiguously
specify the behavior of these functions and services using\r\nQueuing Petri Nets
(QPNs). QPNs are an established method that allows to\r\nexpress queuing, synchronization,
stochastically distributed processing delays,\r\nand changing traffic volume and
characteristics at each VNF. With QPNs,\r\nmultiple VNFs can be connected to complete
network services in any structure,\r\neven specifying bidirectional network services
containing loops.\r\n We discuss how management and orchestration systems can
benefit from our\r\nclear and comprehensive specification approach, leading to
better placement of\r\nVNFs and improved Quality of Service. Another benefit of
formally specifying\r\nnetwork services with QPNs are diverse analysis options,
which allow valuable\r\ninsights such as the distribution of end-to-end delay.
We propose a tool-based\r\nworkflow that supports the specification of network
services and the automatic\r\ngeneration of corresponding simulation code to enable
an in-depth analysis of\r\ntheir behavior and performance."
