StanNet : Infrastructure
 StanNet : a double backbone, Gigabit Ethernet – ATM
 The backbone is powered by
:
 4 high-end core Gigabit Ethernet switches/routers
 providing bandwith from 100Mb/s to 1Gb/s
 using VLAN technology and central routing
 transporting mainly IPv4 traffic
 4 ATM switches with OC-3 interfaces
 providing maximum bandwith up to 155Mb/s
 allowing the configuration of dedicated virtual channels/paths
 transporting specific traffic – IP over ATM, IPv6, telephone
traffic, … -

StanNet : Infrastructure
 Extensibility and flexibility of the infrastructure
 A new client
 construction of a new fiber path –if necessary- easily done
(strategic location of converging points)
 deployment of a new switch connected to the backbone
 creation of a new VLAN –if necessary central routing of this new VLAN on the backbone
 An existing client : migration or extension to another
site
 optional deployment of a new switch
 transport of the VLAN to the new site

StanNet : Services
 Network services
 IPv4 and IPv6 connectivity within the MAN, and to the Internet
 extensibility and scalability of LAN with VLAN
 security inter-VLAN with ACL (Access Control Lists) and central
routing
 support of specific traffic from Renater : IPv6, multicast, …
 System services : classic Internet services
 DNS
: StanNet domain management
 e-mail : e-mail box management (for certain sites)
 Web : web hosting (for certain sites)
 News : providing news service for StanNet

StanNet : Exploitation and operating team
 StanNet network and system services are managed :
 by a team of 5 network engineers and 3 system engineers
 This team is located in the
 inter-university network/computing resource center
 The
has some specific missions :
 provide network and system services
 guarantee the connectivity and the good health of the
network/system
 network/system evolution with technological survey
(development, testing)

StanNet : Exploitation and operating team
 To provide its mission, the CIRIL Team uses several
tools :
 device configuration (telnet, scripts, web-based




administration)
IP and level 2 supervision (netup, traceroute, SNMP)
Security configuration (ACL + scripts)
Security supervision (ACL + syslog )
traffic metrology and statistics with
, a tool
developed by the CIRIL

Lothaire : A WAN for MAN and sites

 a high bandwidth wide area network
 provides network transport for 2 MAN and 32 peripheral sites
 financed and operated by and for the Universities of Lorraine
 entirely operated by the CIRIL and its team of network/system
engineers
 optical fibers of the ATM backbone are leased from France
Telecom
 Lothaire is a regional network, but :
 it has a « user dimension »
 it provides the same functionalities as a MAN
 it’s operated like a MAN

Conclusion
 StanNet and Lothaire are networks with a
« user dimension »
 an obvious dimension for a MAN like StanNet
 a dimension now recognized for Lothaire
 Networks and users « lives » are closely linked :
 users have an effect on networks
 network exploitation must take care of users requests
 An homogeneous operation of the network guarantees
 this interaction between networks and users
 the long and successful life of the network
