MOICANE
Multiple Organisation Interconnection for Collaborative Advanced Network Experiments
Abstract
The MOICANE project investigates several aspects related to providing proper end-to-end quality of service in the future new generation network environment, on both the theoretical and pragmatic points of view. Several network islands will use different access technologies and implement the IETF IP QoS models, namely IntServ and DiffServ, within their access and core IP networks. Advanced new components such as RSVP/IntServ-aware applications, QoS-aware DiffServ border routers and bandwidth brokers will be deployed along with existing equipment. Trials will be then performed to assess the validity of the currently proposed methods for the support and management of QoS IP services in a single and multi-domain context.
Objectives
The project's main goal is to realise a distributed test-bed interconnecting several network islands, characterised by different access technologies and supporting different services, such as tele-lecturing, virtual-classroom, virtual-laboratory. Each island will be based on the IETF architectural models for IP Quality of Service, and will constitute a test-field to assess their effectiveness.
As of January 2002, the architecture, network elements and applications to be deployed are defined and specified. Development of specific network elements and services is in progress. Integration of existing and developed elements and services is scheduled during the second quarter of 2002. Trials are planned during the second half of the same year.
The network islands that compose the MOICANE testbed are shown on the above map: one island in Portugal, four in Italy, two in Greece and two in Romania.
Technical Approach
The project considers three network sections namely the access technology, the access IP network and the core IP network.
Four different access technologies are deployed:
- Current Ethernet-based LANs,
- Asymmetric Digital Subscriber Lines which allow high bit rates on existing subscriber copper lines,
- Wireless, both IEEE 802.11b and 802.15 (Bluetooth) which address mobility related issues,
- WLL, Local Multipoint Distribution Systems which offer broadband communications to residential and business customers via radio link in a limited area from a local base station.
Provisioning of IP QoS is based on the two models defined by the IETF: - IntServ, which makes use of explicit reservation of resources for each individual IP flow, in the access IP network,
- DiffServ, which focuses on aggregates of a number of individual flows having identical sensitivity to the delays and losses introduced by the network, in the core IP network.
Studies within the MOICANE project are related to practical operation, management, and performance of implementations of these models both alone and in combination.
Some specific hardware and software network components are being developed by the partners. Besides existing and new commercial applications running on hosts, specific applications are developed to match the need of the project especially with regard to their RSVP/IntServ awareness. Specific and commercial applications are components of the E-learning and virtual laboratory services that will form the basic traffic for several tests.
Testbed
The islands are using specific as well as commercial network elements and applications. Not all islands will be deploying all access technologies and services. As part of the collaborative work and experiments, each island will focus on a specific access technology and share results and conclusions with other partners. However, all islands will support standard LANs and are expected to support the specific E-learning service. Almost all tests can be conducted within a single island. The extent of tests involving interconnected islands will depend on the precise nature of the national and international links between the islands.
Applications/Results
The project contributes to the advance of the state of the art in access technologies and QoS implementation and to the use of related technologies for new generation networks by:
- implementing components such as:
- QoS-aware DiffServ border router,
- Bandwidth broker,
- End-to-end QoS measurement,
- integrating them with other commercial network elements,
- running distributed trials aiming at testing the effectiveness of proposed methods for allocating and negotiating resources as well as the efficiency of communication protocols between components of the IP network.
Innovation
Innovation within MOICANE is reflected by the following project objectives:
- Study and validation of methods to support QoS to applications inside a single access network and at the access/IP core boundary;
- Validation of methods to manage QoS within a single IP core domain and across multiple IP core domains;
- Validation and tuning of the interconnection by means of tests involving a geographically distributed, heterogeneous test-bed and users.
