We plan gradual implementation of these front-ends: own linear interface, webinterface, command-line interface of Cisco IOS and JUNOS and SNMP. As regardsback-ends, we intend to support Cisco IOS, JUNOS, SNMP in addition toPC routers, or also methods of direct communication between processes, e.g.,XML-RPC.5.6 Project PresentationWithin our presentation activities, we have made efforts to present the IPv6protocol and the results of our project to the general professional public.5.6.1 WebSome years ago, we set up a section focusing on IPv6 within the www.cesnet.czserver. The section provided general information concerning the protocol andFigure 5.7: Server at www.ipv6.cz78 High-speed National Research Network and its New Applications 2002
the activities of our project. In 2002, we decided to change the structure of thispresentation.We set up a new independent server at www.ipv6.cz, in order to populariseIPv6 in the Czech Republic. The server provides information concerning theprotocol and its implementations, description of the current situation and offerssome interesting links. The server also includes mailing lists: ipv6@ipv6.czserves for discussions concerning the practical aspects of IPv6 and the objectiveof the ipv6-peering@ipv6.cz list is to discuss the recommended rules forIPv6 peering.We moved general information concerning the protocol from www.cesnet.cz towww.ipv6.cz and kept there only the pages describing the project. The sectiondevoted to IPv6 at www.cesnet.cz thus offers an information concerning the activitiespursued by CESNET in this respect.As the PC-based Router subproject witnessed a prompt development, it wasnecessary to come up with a corresponding presentation and communicationplatform. As this is a logically integrated issue, to be solved also by researchersoutside CESNET, we considered it adequate to create another independentserver at www.openrouter.net.Figure 5.8: Server at www.openrouter.netHigh-speed National Research Network and its New Applications 200279
