Please fill this in as best as you can for your site. The previous table from 2017 is on page 8 here: https://www.gridpp.ac.uk/wp-content/uploads/2017/10/179_20171004_NetworkForwardLook.pdf

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: 2* 20Gb/s

Tier 2 Connection: 2* 20Gb/s

Forward Look: Expect 100Gb/s

Comments (including any routing and firewall bypass arrangements, DTZ etc):The University are working on 100Gb/s WAN connection and backbone project. We expect the Tier 2 will have a 100Gb/s link with maybe some QoS limits to ensure the rest of University are not starved of access. A data transfer zone is also expected to be implemented.


IPv6 Enabled?: yes

IPv6 Comments: Full IPv6 connectivity for storage and compute.

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: 40Gb (4x10) + two 10Gb link (one temp, one the backup used by the Tier 2)

Tier 2 Connection: Exclusive use of the 10Gb link.

Forward Look: Tier-2 has an imminently pending update to 40Gb. within the next few years will update to 100Gb.

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: 100Gb/s shared

Tier 2 Connection: 10Gb/s + failover currently directly to Janet

Forward Look: 40Gb/s + failover (?)

Comments (including any routing and firewall bypass arrangements, DTZ etc): site will bypass all the university firewall.

IPv6 Enabled?: yes

IPv6 Comments: outgoing IPv6 traffic on all machines, incoming IPV6 traffic only on storage.

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?: currently only on perf sonar

IPv6 Comments: intention to deploy wider in the future.

UKI-SCOTGRID-DURHAM

Institution Janet Connection: 10Gbps

Tier 2 Connection: 10Gbps

Forward Look: Moving to 2x 10Gbps in 2021. Pushing for minimum of 40Gbps by 2022/2023. Wanting to aim for 100Gbps by 2025.

Comments (including any routing and firewall bypass arrangements, DTZ etc): Dedicated Science DMZ for Cluster

IPv6 Enabled?: Yes

IPv6 Comments: Institute isn't IPv6 at all but as we're a Dedicated connection and DMZ, we managed to implement it first.

UKI-SCOTGRID-ECDF

Institution Janet Connection: 100GB to ACF facility https://shapingthefutureofjanet.jiscinvolve.org/wp/technology-innovation/to-100gbit-s-and-beyond/

Tier 2 Connection: 10G currently

Forward Look: plans to improve uplink to EDDIE (Edinburgh Tier2) compute to 20G in 2021, not yet clear if we will get 10G or 20G to/from site storage after this work is completed.

Comments (including any routing and firewall bypass arrangements, DTZ etc): University perimeter firewall gets grumpy when not using valid certificates, but otherwise ntr.

IPv6 Enabled?: yes, enabled on site storage and perfsonar, not expected to be deployed on compute

IPv6 Comments: broadly just works within the university

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: 10Gb/s (I think)

Tier 2 Connection: 10Gb/s

Forward Look: Hoping to fix issue with second 10 Gb/s link bond to get up to 20Gb/s

Comments (including any routing and firewall bypass arrangements, DTZ etc): Grid site is completely outside Uni firewall. Technically, if the uni has problems with their connection they would use ours but that's never happened.

IPv6 Enabled?: Can route traffic but can't assign names

IPv6 Comments: Uni IT says they are unable to do IPv6 DNS assignments. This may have changed recently after a change to their DNS/DHCP management systems though they still seem to be having trouble.


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?:

IPv6 Comments:

All Grid nodes (including worker nodes) are Dual Stack. No plans for IPv6 only nodes yet.

UKI-SOUTHGRID-SUSSEX
