text: 'We study the Online Prize-collecting Node-weighted Steiner Forest problem
(OPC-NWSF) in which we are given an undirected graph \(G=(V, E)\) with \(|V| =
n\) and node-weight function \(w: V \rightarrow \mathcal {R}^+\). A sequence of
k pairs of nodes of G, each associated with a penalty, arrives online. OPC-NWSF
asks to construct a subgraph H such that each pair \(\{s, t\}\) is either connected
(there is a path between s and t in H) or its associated penalty is paid. The
goal is to minimize the weight of H and the total penalties paid. The current
best result for OPC-NWSF is a randomized \(\mathcal {O}(\log ^4 n)\)-competitive
algorithm due to Hajiaghayi et al. (ICALP 2014). We improve this by proposing
a randomized \(\mathcal {O}(\log n \log k)\)-competitive algorithm for OPC-NWSF,
which is optimal up to constant factor since OPC-NWSF has a randomized lower bound
of \(\varOmega (\log ^2 n)\) due to Korman [11]. Moreover, our result also implies
an improvement for two special cases of OPC-NWSF, the Online Prize-collecting
Node-weighted Steiner Tree problem (OPC-NWST) and the Online Node-weighted Steiner
Forest problem (ONWSF). In OPC-NWST, there is a distinguished node which is one
of the nodes in each pair. In ONWSF, all penalties are set to infinity. The currently
best known results for OPC-NWST and ONWSF are a randomized \(\mathcal {O}(\log
^3 n)\)-competitive algorithm due to Hajiaghayi et al. (ICALP 2014) and a randomized
\(\mathcal {O}(\log n \log ^2 k)\)-competitive algorithm due to Hajiaghayi et
al. (FOCS 2013), respectively.'

text: Supporting the vast variety of network services’ management and orchestration
requirements is one of the main challenges that Network Function Virtualization
(NFV) is dealing with. While general management requirements such as Virtual Network
Function (VNF) resource requirements can be specified by the service developers
using service descriptors, specific management operations like VNF-specific configuration
cannot be performed by these descriptors. On the other hand, it is inefficient
and also very challenging for Management and Orchestration (MANO) frameworks to
provide all specific-management operations for every individual network service
and their constituent VNFs. To mitigate this issue, we propose the use of service-specific
programs called Specific Managers (SMs) that can customize management and orchestration
of network services and also extend the capability of MANO frameworks to support
per-service management and orchestration. The results of our evaluation show that
the higher flexibility and programmability enabled by SMs improve the performance
of the service performance and also utilises the service provider resources more
efficiently.

text: "Developing cloud applications using a microservice architecture allows their
functional blocks to be distributed and\r\ndeployed on multiple Cloud infrastructures.
This enables service providers to mix and match Cloud-based microservices and
Virtual Network Functions (VNFs) that are provided by Network Function Virtualization
(NFV). Provisioning complex services containing VNFs and Cloud-based microservices
across NFV and cloud infrastructures can enhance service quality, reduce latency,
and optimise cost. This can be provided by an orchestration system that can handle
cross-ecosystem dependencies. To this end, we implemented Pishahang that is a
framework for jointly managing and orchestrating virtual network functions and
Cloud-based microservices. During the demo, we deploy several complex services
to demonstrate features provided by Pishahang to support management and orchestration
of complex services."

text: "We present CLARC (Cryptographic Library for Anonymous Reputation and Credentials),
an anonymous credentials system (ACS) combined with an anonymous reputation system.\r\n\r\nUsing
CLARC, users can receive attribute-based credentials from issuers. They can efficiently
prove that their credentials satisfy complex (access) policies in a privacy-preserving
way. This implements anonymous access control with complex policies.\r\n\r\nFurthermore,
CLARC is the first ACS that is combined with an anonymous reputation system where
users can anonymously rate services. A user who gets access to a service via a
credential, also anonymously receives a review token to rate the service. If a
user creates more than a single rating, this can be detected by anyone, preventing
users from spamming ratings to sway public opinion.\r\n\r\nTo evaluate feasibility
of our construction, we present an open-source prototype implementation."

text: "Dynamically steering flows through virtualized net- work function instances
is a key enabler for elastic, on-demand deployments of virtualized network functions.
This becomes par- ticular challenging when stateful functions are involved, necessi-
tating state management. The problem with existing solutions is that they typically
embrace state migration and flow rerouting jointly, imposing a huge set of requirements
on the on-boarded VNFs, e.g., solution-specific state management interfaces.\r\nIn
this paper, we introduce the seamless handover proto- col (SHarP). It provides
an easy-to-use, loss-less, and order- preserving flow rerouting mechanism that
is not fixed to a single state management approach. This allows VNF vendors to
implement or use the state management solution of their choice. SHarP supports
these solutions with additional information when flows are migrated. Further,
we show how SHarP significantly reduces the buffer usage at a central (SDN) controller,
which is a typical bottleneck in existing solutions. Our experiments show that
SHarP uses a constant amount of controller buffer, irrespective of the time taken
to migrate the VNF state."

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: Profiling applications on a heterogeneous compute node is challenging since
the way to retrieve data from the resources and interpret them varies between
resource types and manufacturers. This holds especially true for measuring the
energy consumption. In this paper we present Ampehre, a novel open source measurement
framework that allows developers to gather comparable measurements from heterogeneous
compute nodes, e.g., nodes comprising CPU, GPU, and FPGA. We explain the architecture
of Ampehre and detail the measurement process on the example of energy measurements
on CPU and GPU. To characterize the probing effect, we quantitatively analyze
the trade-off between the accuracy of measurements and the CPU load imposed by
Ampehre. Based on this analysis, we are able to specify reasonable combinations
of sampling periods for the different resource types of a compute node.
