Brian Gilmore University of Edinburgh A View from the Campus 5/25/2017 Serenate 1 Context • In UK terms, Edinburgh is a large University with circa 20,000 students • Edinburgh is a heavily research active University 5/25/2017 Serenate 2 Current Position • SuperJANET backbone is 2.5G and 10G • Access speed from SuperJANET is 2x1G. (1 G for e-science – unusual!) • Interior Campus links are mainly 1G • System connections are 10/100 but could be 1G 5/25/2017 Serenate 3 Current Service and Usage • Current service is pure IP • No QoS, no dedicated bandwidth • Usage currently peaks at about 50meg 5/25/2017 Serenate 4 Financing • University funds the capital for the backbone • Schools fund the capital for their networks • Thus upgrades to 1G would be paid for by the School • The recurrent funding for the network is charged to Schools 5/25/2017 Serenate 5 MANs • The SuperJANET (SJ) user base is approx 750 institutions with about 5,000,000 users • Most institutions are connected via their local Metropolitan Area Network (MAN) to SJ • These MANs are a separate management domain with policies etc 5/25/2017 Serenate 6 Stakeholders for the Future • If a new ‘service’ is to be introduced, such as: • QoS • Bandwidth on Demand • Large Bandwidth Demands • Then the following need to be consulted and to agree! 5/25/2017 Serenate 7 Management Domains User School (Dept) University Network Provider (Computing Services) MAN Provider UKERNA 5/25/2017 Serenate 8 Obstacles • The ‘easiest’ levels to address are probably the UKERNA and Computing Services levels • Though the problems of small institutions with limited resources can not be overlooked 5/25/2017 Serenate 9 Obstacles - Continued • The School and MAN levels can offer significant financial and policy level problems • For example, the existence of School level Firewalls is currently a major obstacle to the working of GRID Virtual Organisations and even e-science working in a single Institution! 5/25/2017 Serenate 10 Summary • The ‘last mile’ is still a problem even in campus based networking • Investment at ‘the top’ needs to be matched with investment ‘down below’ 5/25/2017 Serenate 11
