SLAC Network Status

1
SLAC Network - Status Plans

• Transparencies for CCC
• Les Cottrell Dave Millsom
• 10/12/98

2
LAN Growth
Drivers new users, new servers (130 servers _at_
100Mbps), new applications, faster clients,
switches filling up (gt80 full), increased
dependence on avalilability
3
LAN growth

• Build on highly successful switched Enet
• Scalable (Mbps gt Gbps), flexible (VLANs)
• Manageable (isolate problems)
• Available (redundancy, UPS)

4
Next Steps

• Double bandwidth every 12-18 months
• BaBar Network Support -
• SCS - IR-2 Link Farm2
• Structured wiring expansion (8 new locations,
  complete outside radiation fence)
• Core upgrade
• Core switch expansion (internal routing, more
  ports)
• Router upgrade (higher backplane speeds)
• Gbps trunks, phase out 100 Mbps FDDI
• Extend monitoring to switched net

Offsite Access

• Remote access support
• ISDN (production), 56kbps direct modems,
  investigating DSL (128kbpsgt1.5Mbps always on)
• DMZ upgrade
• OC3 (155Mbps) to ESnet for production Spring -
  Summer 1999
• Fiber to Stanford Campus - SSRL Internet2
• NTON (622 Mbps) experiment - WDM

Other Projects

• Security internal firewalls BSD plus MCC, then
  SSRL, BaBar VPNs
• DHCP (production), IMAP LDAP
• Get feet wet with VoIP
