Transcript of "10 fn s36"

  1. 1. FOLLOW-THE-SUN ADAPTIVE-MESH GRID Assumptions: • Round-the-world wavelength ring • Considered example: Grid of 5 fiber-optics connected zero-emission Data Centers (DCs): – 4 solar-powered Data Centers (DCs) at 24/4 = 6 hour of time zone difference apart (e.g. Europe/Africa, Americas, Asia-Pac, ME); – 1 always-on (e.g. wind and/or geothermal powered, electric grid connected) DC • Network connectivity and data center access required at all time zones continuously • However, only two of the data centers need to be active at any time © Optimum Communications Services, Inc. All rights reserved. 1
  2. 2. EXAMPE NETWORK DIAGRAM (1) LEGEND IM 2 x 10Gbps Access ITN Interface Module 4 solar-powered DCs do (at least) 24/4 = 6 hour shifts e.g. 9am-3pm Data center Customer Access Data center at their local time zones, for Asia-Pac Router Americas shortest network latencies during 40 Gbps Wavelength busiest business hours 10 Gbps Access PPP IM IM IM IM Adaptive-Mesh Grid (A-M) IM IM IM IM IM IM Always- ME Europe/ Data center on Africa Data center Data center • A-M ring section provides a dynamically channelized network bus (STS-192 for 10Gbps DC access link) for each egress access port on the local half-ring for transport of data from sources along the bus to the given destination port © Optimum Communications Services, Inc. All rights reserved. 2
  3. 3. EXAMPE NETWORK DIAGRAM (2) LEGEND IM 2 x 10Gbps Access ITN Interface Module 4 solar-powered DCs do (at least) 24/4 = 6 hour shifts e.g. 9am-3pm Data center Customer Access Data center at their local time zones, for Asia-Pac Router Americas shortest network latencies during 40 Gbps Wavelength busiest business hours 10 Gbps Access PPP IM IM IM IM Adaptive-Mesh Grid (A-M) IM IM IM IM IM IM Always- ME Europe/ Data center on Africa Data center Data center • At any given ring section, such a bus is needed per each destination data center on local half ring © Optimum Communications Services, Inc. All rights reserved. 3
  4. 4. EXAMPE NETWORK DIAGRAM (3) LEGEND IM 2 x 10Gbps Access ITN Interface Module 4 solar-powered DCs do (at least) 24/4 = 6 hour shifts e.g. 9am-3pm Data center Customer Access Data center at their local time zones, for Asia-Pac Router Americas shortest network latencies during 40 Gbps Wavelength busiest business hours 10 Gbps Access PPP IM IM IM IM Adaptive-Mesh Grid (A-M) IM IM IM IM IM IM Always- ME Europe/ Data center on Africa Data center Data center • Case of 2 destination DCs per half-ring:  2 (10Gbps) network buses needed on each A-M ring section per each direction © Optimum Communications Services, Inc. All rights reserved. 4
  5. 5. EXAMPE NETWORK DIAGRAM (4) LEGEND IM 2 x 10Gbps Access ITN Interface Module 4 solar-powered DCs do (at least) 24/4 = 6 hour shifts e.g. 9am-3pm Data center Customer Access Data center at their local time zones, for Asia-Pac Router Americas shortest network latencies during 40 Gbps Wavelength busiest business hours 10 Gbps Access PPP IM IM IM IM Adaptive-Mesh Grid (A-M) IM IM IM IM IM IM Always- ME Europe/ Data center on Africa Data center Data center • With entire network doubled, the buses of A-M consume in total 2 x 2 x 10Gbps = 40Gbps of ring capacity, i.e., a single 40G wavelength suffices • Conventionally, for equal performance (single packet hop) network connectivity, 10G wavelength loop needed per each of the 20 10Gbps access ports, for a total of twenty wavelength loops required on the fiber ring, plus 200Gbps of packet switch capacity  Adaptive L1 channelization of A-M grid can reduce network capacity costs by factor of 20:1 © Optimum Communications Services, Inc. All rights reserved. 5
  6. 6. FOLLOW-THE-SUN OPERATION (1) LEGEND IM 2 x 10Gbps Access Each dynamically channelized bus, ITN Interface Module Adaptive-Concatenation Multiplexer Data center Customer Access Data center Bus (AMB), automatically optimizes Asia-Pac Router Americas its L1 capacity allocation among its 40 Gbps Wavelength sources according to realtime traffic 10 Gbps Access PPP load variations IM IM IM IM Adaptive-Mesh Grid (A-M) IM IM IM IM IM IM Always- ME Europe/ Data center on Africa Data center Data center 1) At 9am, solar-powered DC becomes the active DC for new requests, and gets latest process data from the always-on DC © Optimum Communications Services, Inc. All rights reserved. 6
  7. 7. FOLLOW-THE-SUN OPERATION (2) LEGEND IM 2 x 10Gbps Access Each dynamically channelized bus, ITN Interface Module Adaptive-Concatenation Multiplexer Data center Customer Access Data center Bus (AMB), automatically optimizes Asia-Pac Router Americas its L1 capacity allocation among its 40 Gbps Wavelength sources according to realtime traffic 10 Gbps Access PPP load variations IM IM IM IM Adaptive-Mesh Grid (A-M) IM IM IM IM IM IM Always- ME Europe/ Data center on Africa Data center Data center 2) At 3pm, DC stops taking new jobs (which are directed to solar powered DC at -6hr), backs up its data and transfers any remaining processes to always-on DC. AMBs to that destination allocate their capacity to the source IMs at the 3pm DC, for 40Gbps transfer © Optimum Communications Services, Inc. All rights reserved. 7
  8. 8. FOLLOW-THE-SUN OPERATION (3) LEGEND IM 2 x 10Gbps Access Each dynamically channelized bus, ITN Interface Module Adaptive-Concatenation Multiplexer Data center Customer Access Data center Bus (AMB), automatically optimizes Asia-Pac Router Americas its L1 capacity allocation among its 40 Gbps Wavelength sources according to realtime traffic 10 Gbps Access PPP load variations IM IM IM IM Adaptive-Mesh Grid (A-M) IM IM IM IM IM IM Always- ME Europe/ Data center on Africa Data center Data center 3) Outside 9am-3pm from any given time zone, processes get directed to either the current active solar-powered DC or the always-on DC, depending on the distances and the respective loads © Optimum Communications Services, Inc.

  9. 9. FOLLOW-THE-SUN OPERATION (4) LEGEND IM 2 x 10Gbps Access Each dynamically channelized bus, ITN Interface Module Adaptive-Concatenation Multiplexer Data center Customer Access Data center Bus (AMB), automatically optimizes Asia-Pac Router Americas its L1 capacity allocation among its 40 Gbps Wavelength sources according to realtime traffic 10 Gbps Access PPP load variations IM IM IM IM Adaptive-Mesh Grid (A-M) IM IM IM IM IM IM Always- ME Europe/ Data center on Africa Data center Data center  A-M optimizes network capacity allocation automatically according to data load variations, without external signaling/control © Optimum Communications Services, Inc.

  10. 10. DATA CENTER / ACCESS SITE LEGEND IM 2 x 10Gbps Access ITN Interface Module Customer Access Router 40 Gbps Wavelength 10 Gbps Access PPP Adaptive-Mesh Grid (A-M) IM IM IM IM Data Center Server Farm User access network Can be located out of reach of electric grid, Always-on / powered on Client layer techniques as is solar/wind/geothermal when users desire (e.g. GMPLS etc.) can powered be used to form (semi- dynamically) the PPP links between the DCs and routers (incl. through the transparent A-M grid) © Optimum Communications Services, Inc. All rights reserved. 10
  11. 11. BENEFITS (1) • To provide equal network connectivity (i.e. non-oversubscribed full mesh connectivity among the 5 sites with total of 20 10Gbps access points) conventionally would require 20 wavelength loops on the global fiber ring -- instead of just one that suffices for A-M -- plus doubled 200Gbps core router/switch I/O capacity, which can be eliminated with A-M  A-M considerably reduces the materials and electric power needed for the network  A-M reduces cost base for the network by 20:1, making the near-zero-emission data center grid economically viable © Optimum Communications Services, Inc. All rights reserved. 11
  12. 12. BENEFITS (2) • Hardware-automated, automatic network capacity allocation optimization process – programmable logic allows flexible yet straightforward hardware automated control plane, rather than multi-layer distributed software implementation involving complex signaling, middleware etc.  Deterministic, reliable operation required by service providers and enterprises © Optimum Communications Services, Inc. All rights reserved. 12
  13. 13. BENEFITS (3) • Total 24h (always-on DC) + 4x6h (the 4 day-shift DCs) = 2x24 powered-on DC hours, vs. 5x24h that would conventionally be required  5:2 reduction in electricity demand, without significant performance trade-off (and none during peak business hours)  Solar and wind powered IT grids made a technically and commercially sound reality © Optimum Communications Services, Inc.
