Power Line Communication

In May 2003 the HomePlug Powerline Alliance, the industry federation behind the realisation of communications provided through the low voltage electrical network, announced they had drawn up a new draft standard. The new specification - given the name HomePLug AV - is set to simplify the communication between entertainment electronics devices using the low voltage electrical network as the transmission medium.
Since then several manufacturers (e.g. Belkin, Devolo, Linksys, MSI, NETGEAR, Philips, Sharp, ZyXEL, etc.) have been working on the development of data transmission devices that do not require separate cabling and that use the existing low voltage electrical network.
These adapters that can be plugged into the 220 V socket and linked to the USB or Ethernet interfaces of computers are increasingly cheaper here in Hungary now too, and they provide the possibility of setting up networks in a flexible way. They can be used where WiFi cannot be or only with restricted bandwidth - for example, due to reinforced concrete walls. They represent a perfect solution for a network connection for basements, garages, garden sheds or
for any remote point. Their use is advantageous in protected monument buildings, in leased facilities, offices (where there are no network terminals or there is no way of extending the data transmission network). Even security systems, e.g. exterior video cameras, can be set up in this way. A telephone line, IPTV and even an Internet connection can be “extended” using these devices.
Less than 5 minutes are needed to set up the simplest communication (data transmission) network, but a video camera security system requires no more than just 15 minutes to set up.
This time even includes the software installation for the operation of the system as well.
Normal devices are capable of speeds of 200 Mbps, which is double that of the wireless connections existing today, but devices that can reach speeds of 1 Gbps are already available.
Security has been improved with data encryption features.
In my lecture I would like to share with you my practical experiences in connection with the construction of these communication networks, with consideration to the significance of use at home, in education and in the workplace.

The data connection among the computers of the University of Debrecen is materialized through the own optical backbone named UDNet. The metropolitan area network promoted by the World Bank in 1993 and named optical core of the Universitas of Debrecen has been developed significantly till now. Connection to the Internet for the UDNet had been provided exclusively by 10 Gigabit/sec and 2.5 Gigabit/sec optical links, which take part of the national network for research a high education in Hungary, HBONE. The relatively low prices of these high bandwidth HBONE WAN links are induced by the special education and research profile of institutes connected together. For this reason the Hungarian Government directive 20/2004.
(VI.21.) prohibits any profit oriented communication on the HBONE network. This directive pertains only to HBONE WAN links and not to the local network o f universities.
Another recent directive, the law for higher education supports and inspires universities to increase their business oriented activities. Several national and EU calls for proposal (Operative Programs) assess consortium of universities and other companies as candidates.
During these business activities the university and companies joined or established locally should generate business oriented communication, like price lists transmission, business
portals, etc. Companies joined to the university claim extended data communication services (data, voice and video) of the university local network. Conform to the government law mentioned anterior these companies should procure their own links to the Internet.
In our presentation we demonstrate technical details of the impact presented anterior. We exhibit deep routing and switching mechanisms beyond the CCNP knowledge level able to give right solution to this challenge. We present stable virtual routing configurations of partitioning business oriented traffic from the non-business oriented traffic on the local production network. The solution satisfies these apparently two contradictory demands of the Internet-user profile extension by optimal development of the university core network.
Aspects of planning the Hot Spot Systems for universities

The WLAN solution to be used in university environment should provide differentiated and prioritized access to the various network services and servers.
The system proposed by SCI-Network can provide the required unified radio coverage and differentiated and secure wireless access possibility in all buildings of the university and institute campus.
The students and teachers of the different faculties can reach the services of the system (according to location and time) with different priority and security level.
According to the multiple virtual AP technology the radio network delivers specific, and separated traffic (Virtual Services=VLAN in wireless) to the different user groups of the campus.
Beyond the simple network access, extra care should be taken by handling the student’s, teacher’s, guest, employees, and special application’s traffic in a secure, and prioritized way.
Since the WLAN systems are working on the free ISM band (2,4 and 5 GHz), the continuous wireless security monitoring is a basic requirement.
When designing WLAN network customers satisfaction is as important as the building structure, maximizing the coverage and the available bandwidth.
The WLAN system should fit the existing LAN physically and logically, (IP structure, authenticating method) in such a manner, which allows the cost-effective expansion in the future.
The access to the offered services can be limited by different techniques. Inner authentication based on the existing RADIUS or LDAP database, guest users can be authenticated by locally or centralized (on demand).
The connection between the controller and the APs can be L2 or L3. In a routed environment L3 is recommended solution. At those cases where the user traffic should be inspected packet- by-packet (http redirection at web based guest access, time or traffic based subscription) the traffic between the AP and controller is based on a proprietary protocol.
The system supervision is done by the centralized management system, which can be used to overview, control the APs settings, optimize the radio characteristic according to the specific traffic requirements and RF environment. There can be made several statistics and detailed records of the connection sessions, which can be used to track the user and the user accessed servers.
Securing the RF network is based on the RF and wireline LAN network concurrent monitoring, which is done a critical system element called RF Manager. This solution not only capable of detecting RF threats but preventing and actively eliminating the LAN and WLAN attacks.

In our HBONE user community there is an emerging need for L2VPN (Layer-2 Virtual Private Network) service. Reacting to the demands we have evaluated the different
possibilities; the results of the evaluation will be highlighted in the presentation. Based on the possibilities we have already been providing this type of service to two of our member organizations as a pilot. Without the completeness in the presentation some L2VPN technical solutions as well as their usage areas will be shown.
Changing role of e-Infrastructures in the European Research Area
Bálint Lajos dr. <lajos.balint@niifhu>
NI1F Intézet
Gradual evolution of the ERA (the European Research Area) provides completely new opportunities for the scientific research activities in the old continent. Increased mobility of researchers, strengthening of the Research Infrastructures in Europe, pan-European harmonisation of research programs and projects, free movement of information related to research, as well as widening and deepening of global scientific cooperation all these do intensely influence our entire social-economical development and improve overall European competitiveness.
Among the basic ERA objectives, having been set early in the new millennium, there there were, among others, the development of integrated, networked, world class research infrastructures accessible, as a result of applying new generation e-Infrastructures, by research communities working at any part of the world.
In 2007 the EC established an Expert Group on Research Infrastructures for investigating the status and trends of developing and using the research infrastructures. The Final Report of this Expert Group not only drew the attention to the importance of the RIs but also went into details about the questions of improving the infrastructures, by emphasising the special role of e-Infrastructures.
The October 2009 Strategic Foresight of the ERAB, the European Research Area Board, established due to the significance of the ERA by the Commissioner responsible for Research within the European Commission, mentions, as the No. 1 pillar of the ERA related paradigm shift, the pan-European integration of those resources (human, organisational, infrastructural, information, financial ones, etc.), where the e-Infrastructures serve as primary tools of that integration.
Communication between the researchers, dissemination and accessing of scientific information, storing in digital archives enormous amounts of information, connectivity and remote availability of the geographically distributed human and instrument resources, and the operation of those virtual research communities foreseen in the forthcomings is indeed impossible without advanced e-Infrastructures - networking, grid, computing, storing, and collaboration tools as e-Infrastructure components.
The significance of Research Infrastructures and e-Infrastructures is also well proven by the pan-European activities of the ESFRI (European Strategy Forum for Research Infrastructures), the e-IRG (e-Infrastructures Reflection Group), the ENPG (European Networking Policy Group), and the elnfraNet project which soon will merge with the ENPG.
Fast development of the e-Infrastructures will result in one of the most important features of the ERA: a new habit of doing research is gradually emerging a habit characterised by joint efforts, joint responsibilities, joint infrastructures, intense cooperation, high flexibility, and
increased mobility of the researchers getting integrated by this way into global virtual research communities.
Development and operation of the e-Infrastructures should, in this process, step by step turn from traditional server function move to a new, more demanding key role in influencing the effectiveness of the leading edge research activities.
Cisco ASR9000 - MoFRR: Multicast only Fast Reroute Technology
Nagy Tibor <tinagy@cisco.coin>
Cisco Systems Magyarország Kft.
Multiple techniques have been developed and deployed to improve service guarantees, both for multicast video traffic and Video on Demand traffic. Most existing solutions are geared towards finding an alternate path around one or more failed network elements (link, node, path failures). This presentation describes a mechanism for minimizing packet loss in a multicast network when node or link failures occur. Multicast only Fast Re-Route (MoFRR) works by making simple changes to the way selected routers use multicast protocols such as PIM.

Beyond developing the Fiber Channel over Ethernet technology there were introduced several other features. These developments have significant benefits in networks of enterprises and service providers also.
The presentation will briefly highlight the latest development on Nexus platform regarding to hardware and software features.
This presentation is for system engineers and operators who are highly qualified at LAN switching.
Evolution of flexible DWDM networks
Szepesi Zoltán <zszepesi@cisco.com>
Cisco Systems Magyarország Kft.
In the last several year we could noticed a major change in the transport networks. The traditional TDM based networks is being replaced by the native IP or Ethernet based transport, which is running mainly above DWDM system. These courses raise bigger and bigger expectations against the DWDM systems: support of flexible architecture like mesh, simplified design and rapid installation as well as efficient operations.
This presentation summarizes the characteristic of a DWDM system in order to fulfill these requirements, where the Cisco ONS15454 MSTP platforms stands today and what the development directions are. The session also explains those hardware and software features which support the building of a flexible, zero touch transport network as well as includes a status update on the IPoDWDM architecture which has been created by Cisco and now followed by several major industry players.

Because of the significant raise of the capacity demands the number and capacity of the services deployed in a DWDM system have been drastically grown for today together with the increasing variety of the endpoints as well as the much more dynamic behavior of the connections than before. As a consequence, instead of the previously used static kind of point to point DWDM links requiring a huge amount of manual interventions and administrations new generation devices shall be introduced supporting mashed topology efficiently serving any to any connections and offering advanced protection mechanisms, providing efficient end to end management of a huge number of services, where connections can be reprovisioned (deleted or created) remotely within a short time to serve dynamic demands. Thus, element level approach shall be replaced by networking in the DWDM systems. To achieve this we need to introduce new components (like WSS) and architectures (like R/TOADM) on equipment level while network management layer instead of the pure element managers on management level. This presentation entitles networking, key solutions and components and advanced management solutions including novel technique Wavelength Tracker.
