==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 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-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?:

==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-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.
