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: "Despite recent progress in orchestration of Virtual Network Functions (VNFs)
and in multi-technology SDN connectivity, the automated provisioning of end-to-end
network services composed of virtual functions deployed across distributed compute
locations remains an open challenge. This problem is especially relevant to support
the deployment of future 5G networks, comprising virtual access and core network
functions connected through a potentially multi-domain transport network.\r\nIn
this paper, we present and demonstrate the 5GOS, a lightweight end-to-end orchestration
framework that enables the\r\nautomated provisioning of virtual radio access network
services. Using an experimental multi-domain testbed we demonstrate that the 5GOS
can provision multi-domain virtual Wi-Fi and LTE services in less than three minutes."

text: Remarkable advantages of Containers (CNs) over Virtual Machines (VMs) such
as lower overhead and faster startup has gained the attention of Communication
Service Providers (CSPs) as using CNs for providing Virtual Network Functions
(VNFs) can save costs while increasing the service agility. However, as it is
not feasible to realise all types of VNFs in CNs, the coexistence of VMs and CNs
is proposed. To put VMs and CNs together, an orchestration framework that can
chain services across distributed and heterogeneous domains is required. To this
end, we implemented a framework by extending and consolidating state-of-the-art
tools and technologies originated from Network Function Virtualization (NFV),
Software-defined Networking (SDN) and cloud computing environments. This framework
chains services provisioned across Kubernetes and OpenStack domains. During the
demo, we deploy a service consist of CN- and VM-based VNFs to demonstrate different
features provided by our framework.
