UKI-LT2-BRUNEL
Institution Janet Connection: 8 x 10G
Tier 2 Connection:4 x 10G
Forward Look: Covid delayed network upgrade finally started (May/2021). All internal network moving to 100G
Comments (including any routing and firewall bypass arrangements, DTZ etc):
IPv6 Enabled?:
IPv6 Comments:
UKI-LT2-IC-HEP
Institution Janet Connection: 100Gb/s
Tier 2 Connection: 100Gb/s shared
Forward Look:
Comments (including any routing and firewall bypass arrangements, DTZ etc): LHCONE routing enabled
IPv6 Enabled?: Yes
IPv6 Comments:
UKI-LT2-QMUL
Institution Janet Connection:
Tier 2 Connection:
Forward Look:
Comments (including any routing and firewall bypass arrangements, DTZ etc):
IPv6 Enabled?:
IPv6 Comments:
UKI-LT2-RHUL
Institution Janet Connection: 1x10 Gb/s plus second 10 Gb/s backup link
Tier 2 Connection: 1x10 Gb/s plus second 10 Gb/s backup link, dedicated and separate to the institute connection above
Forward Look:
Network manager is in discussions at an early stage with JISC to get a 100 Gb/s link, but this may be shared with other users on campus.
Comments (including any routing and firewall bypass arrangements, DTZ etc): Tier2 has dedicated Janet links which bypass the campus firewall. College occasionally expresses concern about cost implications of our (future) network requirements.
IPv6 Enabled?: No
IPv6 Comments: Networks team is overstretched and cannot cope with our request.
UKI-NORTHGRID-LANCS-HEP
Institution Janet Connection: Waiting on confirmation, was 1 x 10Gb
Tier 2 Connection: Almost exclusive use of the 10Gb "back up link".
Forward Look: Imminent upgrade, details TBC.
Comments (including any routing and firewall bypass arrangements, DTZ etc): Site outside the University firewall.
IPv6 Enabled?: Yes
IPv6 Comments: Enabled for at least the last 4 years.
UKI-NORTHGRID-LIV-HEP
Institution Janet Connection: 2x10G (plus failover 2x10G)
Tier 2 Connection: 1x10G shared, upstream limited to 3G
Forward Look: Hoping to have the upstream throttle removed eventually. Campus network being upgraded to 40/100G.
Comments (including any routing and firewall bypass arrangements, DTZ etc): All traffic through university firewall, but with reduced ACLs. No interest from university in providing bypass/DTZ.
IPv6 Enabled?: None, except for perfsonar servers.
IPv6 Comments: Awaiting university router hardware to be upgraded to allow production IPv6 throughput.
UKI-NORTHGRID-MAN-HEP
Institution Janet Connection:
Tier 2 Connection:
Forward Look:
Comments (including any routing and firewall bypass arrangements, DTZ etc):
IPv6 Enabled?:
IPv6 Comments:
UKI-NORTHRGRID-SHEF-HEP
Institution Janet Connection: None shared 1 x 10Gbps link for LHC / Grid / HPC
Tier 2 Connection: 1 x 10Gbps uplink.
Forward Look: No bandwidth upgrade is planned for LHC / Grid / HPC activities.
Comments (including any routing and firewall bypass arrangements, DTZ etc): All routes through Institution firewall.
IPv6 Enabled?:
IPv6 Comments:
UKI-SCOTGRID-DURHAM
Institution Janet Connection:
Tier 2 Connection:

IPv6 Enabled?:
IPv6 Comments:
UKI-SCOTGRID-ECDF
Institution Janet Connection:
Tier 2 Connection:
Forward Look:
Comments (including any routing and firewall bypass arrangements, DTZ etc):
IPv6 Enabled?:
IPv6 Comments:
UKI-SCOTGRID-GLASGOW
Institution Janet Connection: 2 × 10 Gb/s
Tier 2 Connection: 40 Gb/s
Forward Look: Preliminary discussions (requirements gathering) underway between campus IT Services and Janet.
Comments (including any routing and firewall bypass arrangements, DTZ etc): Current traffic bypasses firewalls with a minimal set of ACLs to restrict certain protocols.
IPv6 Enabled?: Site has IPv6 allocation
IPv6 Comments: IPv6 routed to production cluster for perfSONAR. Networking at campus level is currently under review pending future refresh. IPv6 is currently not routed in hardware, so should be avoided for performance-critical operations (e.g. storage access).
UKI-SOUTHGRID-BHAM-HEP
Institution Janet Connection:
Tier 2 Connection:
Forward Look:
Comments (including any routing and firewall bypass arrangements, DTZ etc):
IPv6 Enabled?:
IPv6 Comments:
UKI-SOUTHGRID-BRIS-HEP
Institution Janet Connection:
Tier 2 Connection: 3 x 10 Gbit/s (10 Gbit/s dedicated + a bit extra)
Forward Look: 100 Gbit/s
Comments (including any routing and firewall bypass arrangements, DTZ etc):
IPv6 Enabled?: yes
IPv6 Comments: internally IPv4 (actively disabled IPv6) due to software restrictions (storage system)
UKI-SOUTHGRID-OX-HEP
Institution Janet Connection: 4 x 10 Gb/s
Tier 2 Connection: 1 x 10Gb/s dedicated
Forward Look:
Comments (including any routing and firewall bypass arrangements, DTZ etc):
University has 20Gb/s (Actually 2*10) with 20Gb/s failover. Grid site has to share the normal routing so in effect is sharing a 10Gb/s link for any single transfer
IPv6 Enabled?:
IPv6 Comments:
UKI-SOUTHGRID-RALPP
Institution Janet Connection:
2x100Gb/s Active + 2x100Gb/s Passive Connections
Tier 2 Connection:
2x40Gb/s from T2 router to the Border routers but 2x10Gb/s bottleneck to the T2 Router
Forward Look:
Hardware procured at the end of last FY to upgrade the T2 router to 2x100Gb/s to the Boarder Routers and 2x100Gb downlink. Discussing connections to the Tier 1 as their network design finalises
Comments (including any routing and firewall bypass arrangements, DTZ etc):
Tier 2 Network is a DTZ and is connected to LHCONE
IPv6 Enabled?:
Yes
IPv6 Comments:
All Grid nodes (including worker nodes) are Dual Stack. No plans for IPv6 only nodes yet.
