Advanced architecture and services Implications of the CEF Networks workshop Michal Hažlinský Lada Altmannová , Jan Nejman, Stanislav Šíma, Josef Verich, Josef Vojtěch Copenhagen, November 21th, 2012 Network Architects Workshop 1
Outline 1. Mission of R&E Networks 2. CESNET Integrated Facility 3. Advanced services of CESNET IF 4. Carrier Ethernet in CESNET Copenhagen, November 21th, 2012 Network Architects Workshop 2
Extensions of the R&E networks - Motivation • To use the full potential of global networking – Applications running in parallel to Internet – Experimental networks (testbeds), research and science support – To use resources more effectively (especially fiber footprint) • To activate new requirements of users – Demanding real time applications – Network control of instruments and processes – Network Aided Design Copenhagen, November 21th, 2012 Network Architects Workshop 3
Recommendations of the 7th CEF Networks Workshop (1) • provide reliable environment for innovations especially by end users • test and deploy leading-edge components and devices requested by new applications • provide space for unconventional ideas and set-ups • collaborate with vendors on scientific and pilot projects not known from telco networks and services • develop multi-vendor experimental facilities available to end users • ensure possibilities of CBFs are evaluated and used Copenhagen, November 21th, 2012 Network Architects Workshop 4
Recommendations of the 7th CEF Networks Workshop (2) • ensure that new applications like atomic clocks comparison or ultra-stable frequency transfer are not blocked in NRENs • investigate possibilities for dark fiber testbed in European scale • investigate possibilities of alien wavelengths deployment especially in international environment • recollect that not only high speed (100G and beyond) networking is cutting-edge but new networking topics arrived • collaborate actively with new projects (e.g. metrology) and provide information on how NRENs can help and provide new services Copenhagen, November 21th, 2012 Network Architects Workshop 5
Extensions of the R&E networks mission Development towards Integrated Facility which: • Is available to users in form of Facility as a Service (FaaS) • Integrates production network services, experimental facility services, testbed services, network fabric services, etc. • Enables potentially disruptive experimentation, keeping production network services running reliably • Share Fiber footprint for all its services (production, experimental and potentially disruptive) • Is built on a System of interconnected computer networks Copenhagen, November 21th, 2012 Network Architects Workshop 6
System of interconnected computer networks Wikipedia: “ The Internet is a global system of interconnected computer networks… “ The situation was changed: The Internet is one application of a global system of interconnected computer networks… Non-Internet Applications (NIAs) running in parallel to the internet. • Precise time and frequency transfer • Remote instrument control and monitoring • Time-critical real-time applications The future Internet will probably include a part of today‘s NIAs. Photonic services enable the building of Integrated Facility. Copenhagen, November 21th, 2012 Network Architects Workshop 7
Disruptive network technologies ? • A number of testbeds have been funded in recent years to explore and prototype the dynamic instantiation of insulated network environments that can be used to test and evaluate disruptive network technologies. It is affordable from cost point of view for lambda testbeds and higher layers! • The purpose of dark fibre experimentation is very different: to prepare cost effective use of dark fibres for needs of R&E Community. These technologies require realistic traffic loads in order to evaluate network behaviour at scale. • Proved approach is: – Design and testing period (typically about 3 month) for understanding risks of disruption and to reach stable solution setup – for example to avoid negative mutual influence of adjacent channels – Long term operation period with parallel running of experimental and production services (for example frequency transfer on RENATER backbone or time transfer on Prague-Vienna line) Copenhagen, November 21th, 2012 Network Architects Workshop 8
Importance Integrated facility brings freedom in experimentation on networks. • Independence on traditional network architectures and protocols Various scientific, engineering and technical fields will benefit from the NIAs. • Metrology (time and frequency), fundamental physics, geophysics, next- generation network synchronization, essential timing backup for vital systems in case of GPS outages (mobile telecom network, power grid, …) Copenhagen, November 21th, 2012 Network Architects Workshop 9
Integrated Facility in CESNET Copenhagen, November 21th, 2012 Network Architects Workshop 10
Integrated Facility in Prague Use for experimental and regular traffic Copenhagen, November 21th, 2012 Network Architects Workshop 11
Integrated Facility in CESNET To divide CEF Network fibers into production and experimental footprint is considered harmful. • it is useful to enable experiments on the production network (for experts) – Test of multivendor 100 Gb/s data transmissions (http://www.ces.net/doc/press/2011/pr110909.html) • it is useful to enable production traffic on experimental lines (it is effective to use free bandwidth) Deployment of one‘s own R&D results • Verification of R&D results • Increasing FaaS strength in limited funding • real-life large examples: single fiber bidirectional lines , Open DWDM photonic system developed by CESNET Copenhagen, November 21th, 2012 Network Architects Workshop 12

CESNET Photonic Photonic Service End-to-End connection between two or more places in an optical network. Described by its photonic path and allocated bandwidth. – physical route that light travels from the one point to another – reserved part of system spectrum along the entire path – fully transparent network – All-optical path, no OEO conversion Copenhagen, November 21th, 2012 Network Architects Workshop 14
CESNET Photonic Provides : – Minimal and constant latency (negligible jitter) – Stable service availability – Future-proof design thanks to grid-less bandwidth allocation Challenges : – Limited service reach due to missing universal all-optical regeneration Photonic services allows FaaS.
