Phosphorus grid-enabled GMPLS control plane (G MPLS): architectures, services, and interfaces

G2MPLS is a network control plane architecture that implements the concept of grid network services. In the framework of the 1ST Phosphorus project, GNS allows the provisioning of network and grid resources in a single step through a set of seamlessly integrated procedures. The implementation of GNS imposes a number of requirements in the control planes of the underlying network infrastructure. This article describes services such as GNS set up and restoration, GNS resource and service discovery, and advance reservation services, which are the main trigger factors of the G2MPLS control plane architectures. The article provides an overview of overlay architecture prior to turning to the main focus of the article, which is the integrated architecture through service procedures and the grid-enabled network interfaces provided by the Phosphorus project.

Energy efficiency considerations in integrated IT and optical network resilient infrastructures

The European Integrated Project GEYSERS - Generalised Architecture for Dynamic Infrastructure Services - is concentrating on infrastructures incorporating integrated optical network and IT resources in support of the Future Internet with special emphasis on cloud computing. More specifically GEYSERS proposes the concept of Virtual Infrastructures over one or more interconnected Physical Infrastructures comprising both network and IT resources. Taking into consideration the energy consumption levels associated with the ICT today and the expansion of the Internet in size and complexity, that incurring increased energy consumption of both IT and network resources, energy efficient infrastructure design becomes critical. To address this need, in the framework of GEYSERS, we propose energy efficient design of infrastructures incorporating integrated optical network and IT resources, supporting resilient end-to-end services. Our modeling results quantify significant energy savings of the proposed solution by jointly optimizing the allocation of both network and IT resources.

Architectural approaches for the integration of the service plane and control plane in optical networks

This paper presents some instantiations of novel application-aware network architectures for emerging IT services and future Internet applications. It proposes and analyses network architectures where the Control and Service Planes are closely and seamlessly interacting with the applications. One instantiation, the Grid-GMPLS (G^2MPLS, as defined by the Phosphorus project) is presented, which implements the Network Control Plane (NCP) architecture for the support of Grid Network Services (GNS). The GNS allows the provisioning of network and HPC/Grid resources in a single-step through a set of seamlessly integrated procedures. In a second example of instantiation, a quite popular application in signalling, i.e. the Session Initiation Protocol (SIP), is integrated with the Optical Burst Switched (OBS) network technology. The SIP-enabled OBS network can be used to manage application sessions and provide network and IT services according to application requirements. This paper investigates the requirements that these new integrated architectures impose on supporting network Control and Service Planes, and technologies, and discusses their possible implementations.

First experiences with the Polish optical Internet

Abstract The paper describes the new development programme of the Polish information infrastructure. The programme, called in Polish PIONIER: (English—PIONEER) Polish Optical Internet, Advanced Applications, Services and Technologies for the Information Society, has been proposed to the Polish State Committee for Scientific Research and has been accepted. The aim of the programme is to create an advanced infrastructure together with tools, services and applications available to the entire scientific community and eventually to government and local administrations as well as society in general. Services and applications are expected to appear as selected pilot realizations in order to verify deployed technologies. Some of the pilot realizations and testbeds are also presented in the paper.

New approach for management services with a Web browser

Abstract This paper presents a new approach for integrated management services, which depend on the use of a Web browser for access to MIB objects. This approach allows the user to perform network management from any host on the network, guarantees the safety of transmissions between the Web browser and the server and permits the visualization of variables of the MIB in different ways. The most interesting feature is the possibility for the user to define the appearance of the management interface. The system, called WebMan , was implemented at the Poznan Supercomputing and Networking Center (PSNC) and it is now in production for management of its UPS devices.

Deployment and Interoperability of the Phosphorus Grid Enabled GMPLS (G2MPLS) Control Plane

Grid-GMPLS (G2MPLS) is conceived as a powerful network control plane solution that enhances the standard ASON/GMPLS architecture providing single-step resource reservation, co-allocation and maintenance of both network and Grid resources. This paper identifies and discusses the main issues and considerations that arise by network research and educational networks and network operators in order to facilitate the dissemination of G2MPLS control plane. Interoperability issues and backwards compatibility with existing network control planes centre the scope of this study, which intends to demonstrate the feasibility of adopting the proposed architectures.

Polish contribution to the worldwide LHC computing

The computing requirements of LHC experiments, as well as their computing models, are briefly presented. The origin of grid technology and its development in high energy community is outlined, including the Polish participation. The LHC Computing Grid project and its successor, the Worldwide LHC Computing Grid, are presented, including the summary of its successful operations in the first years of LHC data gathering. Against such a background, the creation and operation of the Polish Tier-2 is described, including examples of its use by the LHC experiments.

Programmable Abstraction of Datapath

Despite continuous developments in this area, Software Defined Networking (SDN) still seeks for a flexible way of defining a network device behaviour. The control plane needs to be able to fully utilize growing capabilities of modern networking hardware and its diversity. In this paper we propose a new hardware abstraction for various network devices (network processors, optical devices and access devices). The first goal of this proposal is to expose advanced programmability capabilities of network processors and software switches. The second goal of our proposal is to extend the concept of the network node programmability by giving a possibility to dynamically check capabilities supported by a particular network device. The third goal of this paper is to introduce programming language which use new-defined API to Programmable Abstraction of Datapath (PAD) for different kind of network devices. The presented solution ensures therefore flexibility and adaptability of the new programmable functions to specific requirements of a device. The proposed solution creates a unified way of controlling and configuring a variety of families of network devices from optical switches to x86-based appliances.
