MidMAN3 Technical Briefing Welcome
MidMAN3 Technical Briefing Roland Trice JANET Technical Design Manager roland.trice@ja.net
Overview • Introductions Rolly Trice • Network Overview Rolly Trice • NTL perspective Mark Woodley • Project planning Neil Shewry and Rollout • Q&A session All
Introductions • JANET(UK) • Rolly Trice, Regional Delivery Group Manager • Neil Shewry MidMAN3 Rollout Manager • ntl:Telewest Business • Tony Foster Network Designer • Jim Offord Project Manager • Mark Woodley Account Manager
Background • MidMAN board • Did not wish to operate beyond Sept 08 • RPAN 2.5 expires at end of September • MidMAN2 contract expires early October • JANET(UK) • Procure new network • Operate new network
Procurement • Competitive Dialogue August 2008 • PQQ process • Five short-listed bidders entered dialogue • Cable & Wireless • EasyNET • ntl • Synetrix • Thus
Procurement Aims • More bandwidth • In the core and to the institutions • Enhanced Resilience • In the core and for institutions • The option of 100 Mbit/s for FE ** ** See funding caveats later
Procurement Aims • JANET Lightpath services to HEIs • Dedicated bandwidth for • Research • High volume operational traffic (LHC to RAL) • Connection of Local Authorities • “Corporate” as well as “child services” • Enhance regional aggregation • Connection to GSI
Procurement Panel • Lead by Bob Day • Senior JANET(UK) staff involved • Stakeholders • Mike Abel MidMAN Board • Carol Sandys Uni of Birmingham • Max Cains Uni of Wolverhampton • Steve Horsfield WMRBC • Jonathan Jones LA procurement overseer
Approved Supplier • Panel decision in March • ntl/Telewest • Best technical bid • Most economically advantageous • Contract signature imminent • The hard work really begins NOW
Network Features • 10 Gbit/s resilient core • Dedicated to MidMAN • Fibre path diversity • within the MidMAN core • between the MidMAN core and SJ5

Network Features • Note: use of SJ5 for core resilience • Cost of additional 10 Gbit/s better spent building resilience to outlying PoPs • Will be kept under review • 1 GE for HEIs • Backup circuits available over diversely routed fibres for resilience • 100 Mbit/s costed for all FEIs**
Network Features • All circuits are ethernet • RNEP links to MidMAN core • All HEIs to be offered resilience • Bham & Warwick resilience • Circuit to a Core PoP as well as connection “under the floor” at RNEP
Network Features • Core PoPs • On 10 Gbit/s core are all ntl Pops • Carrier grade co-location facilities • Aggregation PoPs • College or Local Authority sites • Lightweight PoP contracts required • Will be written shortly
Points to note • Aggregation in all PoPs • At Layer 3, By JANET(UK) • Better management visibility • Hereford, Shropshire & Staffordshire are still SPoF • We will work with ntl on ways to mitigate these risks
Backup Links • Ethernet circuits have poor OAM • Link loss passed through • Signals a hard failure • Won’t detect partial failure • Keep both links active • Traffic over both links will show packet loss if links become “flaky”
Lightpath Services • Present at the RNEPs as 1GE circuits • Contract used to call off point to point GE circuits between RNEPs and HEIs.
Project Board • Overall direction of the network build • Will close once the network is complete • JANET(UK) • Senior management & technical staff • MidMAN, • Willing volunteers will be sought this pm • Local Authorities • WMnet
Project Management • Neil Shewry • Project Manager • Tony Hacche • Senior IP engineer • Timescales are tight but achievable • Regular updates for MidMAN sites
Site Surveys • ntl and BT have already started • Planning of the fibre route • into campus • across campus • into buildings, comms rooms to the rack
Site Surveys • ntl and BT have already started • Planning of the fibre route • into campus, across campus • into buildings, to comms rooms & the rack • Wayleaves • Permission to route fibre • Please expedite signature
Circuit termination • 10 & 100 Mbit/s ethernet • Electrical presentation, RJ45 • 1 Gbit/s ethernet • Optical presentation, • Multimode fibre with SC connectors
Circuit termination • ntl equipment at PoPs • Needs 19” rack space • H 135mm W 485mm 255mm • Weight 4.0 Kg • A 13 amp socket • ntl equipment at sites • Needs 19” rack space • H 45mm W 145mm 265mm • Weight 1.7 Kg • A 13 amp socket
Transition • Network handover by end June 2008 • Transition must be complete by end September • Access link testing • Left looped at B-end by ntl • JANET NOC tests around the loop • Hopefully the test works • You take loop off when asked • Hopefully, the test fails
Transition • New /30 address will be allocated • Institutions on JANET MRS • Secondary addresses for links • JANET NOC will manage transition • Transitions planned for Tuesday mornings 07:00-0900 • Can be at other times to suit you • Fridays & weekends not good
LSC Upgrade Programme • Fund CAPITAL for bandwidth upgrades • Typically from 10 to 100 Mbit/s • Sites must fund recurrent costs • In MidMAN3 • If ntl has offered 100 Mbit/s circuit in their response, there will be no cost to upgrade • If MidMAN3 recurrent <= MidMAN2 recurrent there will be no cost to upgrade
LSC Upgrade Programme • Otherwise, institution pays the difference between MidMAN3 10 Mbit/s cost and MidMAN3 100 Mbit/s cost • Applying LSC national policy • There may be oddities • Sites that are physically close may not be treated the same • 10 Mbit/s circuits still zero cost to site
