“…The EU-Japan STRAUSS project proposed a multi-domain SDN architecture where the network orchestrator acted as a unified transport network control layer, which enables end-to-end resources orchestration across multiple domains with heterogeneous technologies [2]. The authors in [3] demonstrated a network orchestrator provisioning end-toend optical services with SDN controllers, but without any common interface. Therefore, the work in [3] lacked a standard interface to operate the optical domains.…”

“…Typically, domain SDN controllers have a northbound interface (NBI) which is technology and vendor dependent, so the Network Orchestrator has to implement different plugins for each of the domain SDN controller's NBI [7]. During the latest OIF/ONF Transport SDN demonstration [8], vendors tested prototypes of SDN controllers NBI for Service Request and Topology functions in development by the OIF.…”

Due to the importance for network operators of dynamically control networks (in contrast to what has been deployed until now), this paper proposes a technical solution based on an SDN architecture. With the introduction of an endto-end (E2E) SDN architecture, it is possible to support an E2E service from access to backbone networks. This paper firstly presents an optimum end-to-end network architecture, which covers both network domains. A transport API is introduced (Control Orchestration Protocol protocol) and it is used for joint network orchestration between network controllers, in order to provide these E2E services. Finally, this paper presents a multipartner demonstration, which involves two different labs, located in Telefonica and Trinity College of Dublin facilities. This demonstration is used to validate this work.

“…These have simplified infrastructure configuration for data centre servers, storage, as well as core and edge networks. As a result, the infrastructure is able to [127,81,17] [ 42,140,153,100,164,163,132,131,116,170,70,156,44,95,79,107] [ 106,53,46,166,128,64] adapt to the needs of the services that run on it, making the interplay between the services and the infrastructure more dynamic and complex.…”

Fog/edge computing, function as a service, and programmable infrastructures, like software-defined networking or network function virtualisation, are becoming ubiquitously used in modern Information Technology infrastructures. These technologies change the characteristics and capabilities of the underlying computational substrate where services run (e.g. higher volatility, scarcer computational power, or programmability). As a consequence, the nature of the services that can be run on them changes too (smaller codebases, more fragmented state, etc.). These changes bring new requirements for service orchestrators, which need to evolve so as to support new scenarios where a close interaction between service and infrastructure becomes essential to deliver a seamless user experience. Here, we present the challenges brought forward by this new breed of technologies and where current orchestration techniques stand with regards to the new challenges. We also present a set of promising technologies that can help tame this brave new world.
