“…The ONOS has been used today in variety of applications ranging from multilayer network control to datacenters [38]. Major use cases of ONOS includes CORD (Central Office Rearchitected as a Datacenter [39], [40], Multi-Layer Network Control, Migrating MPLS Network, and Global Research Network Development. ONOS also provides its partner driven use cases such as Huawei Agile L3 VP, Huawei Enterprise CPE, DirectTV Multicast and NEC Transport SDN.…”

Abstract-Software Defined Networking (SDN) is an emerging network paradigm that provides central control over the network. Although, this simplifies the network management and makes efficient use of network resources, it introduces new threats to network reliability and scalability. In fact, a single centralized controller is a single point of failure. Moreover, a single controller may become a performance bottleneck as processing overhead increases. Distributed SDN controller platforms improve the reliability and scalability to some extent, however they remain vulnerable to Distributed Denial of Service (DDoS) attacks, specifically on control plane. We believe that there is a need for a distributed controller framework that is capable of providing service continuity without performance degradation in case of excessive network traffic or DDoS attacks on controller. In this paper, we aim to address the vulnerabilities of SDN control plane. We propose and implement an efficient and Resilient Controller for Software Defined Network (ReCSDN). This framework is capable of detecting and mitigating DDoS attacks timely and ensures the continuity of services without performance degradation. We created an experimental test bed using Mininet to conduct extensive experiments. We deployed ReCSDN on top of Open Network Operating System (ONOS) cluster to confirm the viability of our approach. The experiment results show that with ReCSDN, control plane is not only able to withstand excessive network load but will also continue to provide services in case of any controller failure.

While the cost of the access network could be considerably reduced by the use of caching, this is not currently happening because content providers (CPs), who alone have the detailed demand data required for optimal content placement, have no natural incentive to use them to minimize access network operator (ANO) expenditure. We argue that ANOs should therefore provide such an incentive in the form of direct subsidies paid to the CPs in proportion to the realized savings. We apply coalition game theory to design the required subsidy framework and propose a distributed algorithm, based on Lagrangian decomposition, allowing ANOs and CPs to collectively realize the optimal memory for bandwidth tradeoff. The considered access network is a cache hierarchy with per-CP central office caches, accessed by all ANOs, at the apex, and per-ANO dedicated bandwidth and storage resources at the lower levels, including wireless base stations, that must be shared by multiple CPs.

Intent‐based service management for heterogeneous software‐defined infrastructure domains

Summary One of the main challenges in delivering end‐to‐end service chains across multiple software‐defined networking (SDN) and network function virtualization (NFV) domains is to achieve unified management and orchestration functions. A very critical aspect is the definition of an open, vendor‐agnostic, and interoperable northbound interface (NBI) that should be as abstract as possible and decoupled from domain‐specific data and control plane technologies. In this paper, we propose a reference architecture and an intent‐based NBI for end‐to‐end service management across multiple technological domains. The general approach is tested in a heterogeneous OpenFlow/Internet‐of‐Things (IoT) SDN test bed, where the proposed solution is applied to a rather complex service provisioning scenario spanning three different technological domains: an IoT infrastructure deployment, a cloud‐based data collection, processing, and publishing platform, and a transport domain over a geographic network interconnecting the IoT domain and the data center hosting the cloud services.
