    39 Experiment consists in changing the light path from ToR1<-->ToR2 to ToR1<-->ToR3, representing changing of the light path in C-RAN when “Client” wants to move its base-band processing from “Edge Cloud” to “Central Cloud”.
    40 
    41 Experiment includes 3 servers:
    42 {{{
    43 srv1-lg1.bed.cosmos-lab.org
    44 srv2-lg1.bed.cosmos-lab.org
    45 srv3-lg1.bed.cosmos-lab.org
    46 }}}
    47 
    48 Experiment includes 4 ROADMs:
    49 {{{
    50 roadm1-co1.cosmos-lab.org (10.104.1.1)
    51 roadm2-co1.cosmos-lab.org (10.104.1.2)
    52 roadm3-co1.cosmos-lab.org (10.104.1.3)
    53 roadm4-co1.cosmos-lab.org (10.104.1.4)
    54 }}}
    55 
    56 
    57 3 interfaces are connected to these servers from data1 pool of ToR interfaces:
    58 
    59 {{{
    60 twentyFiveGigE 1/1/1 <--> srv1-lg1.bed.cosmos-lab.org
    61 twentyFiveGigE 1/1/2 <--> srv2-lg1.bed.cosmos-lab.org
    62 twentyFiveGigE 1/1/3<--> srv3-lg1.bed.cosmos-lab.org
    63 }}}
    64 
    65 
    66 3 interfaces and 3 transceivers are associated with them in vlans:
    67 
    68 {{{
    69 vlan 121: twentyFiveGigE 1/1/1 ; tengigabitethernet 1/32/1;
    70 vlan 122: twentyFiveGigE 1/1/2;  tengigabitethernet 1/29/1;
    71 vlan 123: twentyFiveGigE 1/1/2;  tengigabitethernet 1/31/1;
    72 }}}
    73 
    74 
    75 We are assigning next wavelengths to tengigabitethernet:
    76 
    77 {{{
    78 1553,30 nm 193,00 with bandwidth ~[192.95;193.05] Thz
    79 }}}
     39This experiment demonstrates optical switching between the short (1-hop) path, between {{{srv1-co1}}} and {{{srv1-lg1}}}, and the long (2-hop) path, between {{{srv1-co1}}} and {{{srv2-lg1}}}. It represents changing of the light path in C-RAN when a "Client" wants to dynamically change its base-band processing location between a nearby "Edge Cloud" and a further away "Central Cloud".

     41This experiment uses 3 servers and 4 ROADM units from the {{{bed.cosmos-lab.org}}} domain:
     42{{{
     43srv1-co1.bed, srv1-lg1.bed, srv2-lg1.bed
     44rdm1-co1 (10.104.1.1), rdm2-co1 (10.104.1.2), rdm1-lg1 (10.104.2.1), rdm2-lg1 (10.104.2.2)
     45}}}
     46
     47Setup for the ToR switches ({{{da-sw-co1}}} and {{{da-sw-lg1}}}), 10G DWDM tunable sfp+ transceivers, and vlan:
     48{{{
     49(da-sw-co1) vlan 1066: Eth 1/1/1:1 (srv1-co1 data1);  Eth 1/1/66 (10g dwdm tunable);
