Alcatel 7770

Alcatel 7770

• The Alcatel 7770 at Cern is now connected to the
  Datatag testbed and to the CERN production
  Network
• It receives the full BGP routing table and it is
  ready to be connected to the VTHD line to Lyon
  (in case this option could be interesting for
  VTHD and INRIA).
• QoS
• Based on DiffServ model
• It couldn't be a AS border router, i.e. DSCP
  (re)marking is not supported.

Alcatel 1670

• The 25th of February 2003 the STM16 line from
  CERN to Starligth will be reconfigured in a 16 x
  VC4 stm16 (not concatenated) in order to be
  connected to the Alcatel 1670 multiplexers.
• Then two cross connections between the
  Gigaethernet ports will be defined. This will
  provide two layer 2 indipendent 1GBEth
  connections between CERN and STARLIGHT.

• More flexibility each connection could be used
  at L2 or L3, one indipendently from the other.
• L2
• Each link could connect two remote LANs
• The links could be bundled together to have a
  2Gbps trunk
• L3
• Two different paths for the same location
  (backup?)
• Equal cost path load balancing vs. trunking

Available Interfaces

• After the STM16 configuration there will be
  available
• Alcatel 7770 in Geneva and Chicago 2xSTM16 and
  7x1GBE
• Cisco 7606 in Geneva and Chicago 1xSTM16 and
  several 1GBE
• Juniper M10 in Chicago 1xSTM16 and 1xGBE

these GBE interfaces cannot be connected to a
switch.

Juniper routers

• The STM16 backup connection to Geant is now
  connected to the Juniper M10 router. The line has
  been moved from a CERN production Cisco 7600
  since the latter doesn't support MPLS TE. This is
  necessary to define the CCC connection between
  CERN and CNAF.
• The LSPs needed for the CCC tunnel are already
  configured, but there are still some problems and
  the L2 connection is still not running.
