Context

• Use of gt 2 Mbps FEC links to MAN
• particularly LES 2/10/100
• need for upgrade options for FECs
• England only
• Scotland, Wales central initiatives with extra
  funds to RNOs
• Northern Ireland no MAN (yet)

4
Context continued

• FEC needs to be seen to pay for more than 2 Mbps
  to JANET
• FEC ? UKERNA ? RNO flow must be self-funding
• need to offer upgrades that are attractive to
  FECs - amount and price
• Need reasonably simple scheme

5
LES 2/10 vs 2 Mbps serial

• Use of LES 2/10 to reduce access cost
• where cheaper than 2 Mbps serial links
• RNO decision
• RNO has freedom to police to 2 Mbps (in routers
  if it wants)
• benefit to RNO better management of telecomms.
  budget

6
Upgrade to 4 Mbps

• FEC requests gt 2 Mbps to JANET
• request made to UKERNA (as provider of Primary
  Connection)
• 2 ? 2 Mbps implementation payment to RNO as
  already established
• LES 2/10 implementation propose notional transit
  payment at 1,274 per Mbps
• RNO can police to 4 Mbps if wishes

7
Upgrade to 10 Mbps

• Only where LES2/10 available
• propose addition to funding modelaccess based
  on BT tariff, plus transit assume 7 Mbps max.
  effective throughput ? additional 6,370 transit
  contribution

8
Upgrade to 100 Mbps

• Same model as for LES2/10
• access based on BT LES100 tariff
• but transit based on JANET bandwidth agreed with
  FEC
• MAN free to police through router
• contractual proviso on FEC to purchase more
  bandwidth if it persistently runs above agreed
  amount on access link

9
High bandwidth FEC connections to MAN

• but not to JANET
• e.g. for local collaborations, with high
  intra-MAN traffic flows
• do we need to cater for this?
• if so propose to make it the RNOs responsibility
  to negotiate prices and to keep traffic to JANET
  to contracted level

10
Multi-site FEC connections

• Propose to leave at MANs discretion whether to
  provide and at what price
• where so, treat (largest site of) highest
  bandwidth connection(s) as the Nominated
  Connection
