The onset and progression of immune-mediated inflammatory arthritis, such as rheumatoid arthritis and spondyloarthritis, are linked to the IL23-IL17 immune axis, so that many therapeutic strategies aim at modulating this pathway. However, there is so far no possibility of an in vivo direct monitoring, without a biopsy, of the specific T cells involved in this modulation. Synovial perfusion, and thus...
The simple network management protocol (SNMP) Framework, is one of the most diffused and successful protocol for network management generally available in current network devices.This work studies the dynamic evolution of the SNMP management information based (MIBs) of commercial IP/MPLS routers and evaluates the effectiveness of the relevant implementation. In addition, it characterizes the MIB modules...
Within the ITU-T next generation network (NGN) architecture, the resource admission control function (RACF) has been designated to perform the application-driven QoS control across both access and core networks. However, an actual RACF implementation acting on MPLS metro-core networks does not exist since RACF lacks of the capability to configure QoS policies on MPLS network nodes. This prevents an...
This paper reports the experimental validation of a SIP-based service platform for optical transport networks. The platform enables applications to trigger network resource reservation during the session signaling thanks to a consistent network node configuration.
A service oriented optical network (SOON) architecture for control plane enabled transport network is described and assessed. The relevant service plane is also described in terms of functional blocks and interfaces.
This paper presents a service-oriented multi-granular multi-format network demonstrator. Service-oriented wavelength and sub-wavelengthnetwork connection establishment is being demonstrated by utilising SOON-JIT protocols to support VoD HD and Quad-HD multi-media applications.
This paper presents multi-granular OBS node architectures able to manage multiservice traffic according to the required Quality-of-Service (QoS). These nodes exploit fast and slow switching devices to obtain scalable and cost-effective network.
The virtual private line service (VPLS) represents an attractive solution for enterprise customers requiring ldquotransparent LAN servicerdquo among remote sites and across a MPLS core network. In this context, the QoS enforcement is a challenge due to the high expectation of customers that require the same guarantees as a private network. This paper describes the implementation of a dynamic QoS control...
Next generation network (NGN) Release 1 is the ITU- T architecture for packet-switched networks that supports the provisioning of broadband and QoS-guaranteed multimedia services, such as Video on Demand and TV streaming, independently of the underlying network transport technologies. Control plane (CP)-enabled transport networks might be a candidate to support NGN services in the Metro/Core segment...
Applications such as grid computing, storage or video-on-demand may need the provisioning by a transport network of ad-hoc secure end-to-end connections with guaranteed bandwidth, latency and resilience. The service plane (SP) is a functional layer, proposed by the authors, that enhances the automatically switched transport network (ASTN) for the provisioning of network services with a level of abstraction...
This paper presents the architecture, some specific supporting functions and an experimental validation of a new functional plane, namely the service plane, for realizing an added-value service provisioning (e.g., grid connectivity) for telecommunication operators. First, it is shown as the service plane can be a viable solution for decoupling service and transport development, by masking the transport-related...
The object of this paper is the experimental validation of the service plane functionality for supporting application-initiated invocation of a virtual private network service in transport networks.
