 Figure 1. Topology setup of the experiment.
 
-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”.
-
-Experiment includes 3 servers:
-{{{
-srv1-lg1.bed.cosmos-lab.org
-srv2-lg1.bed.cosmos-lab.org
-srv3-lg1.bed.cosmos-lab.org
-}}}
-
-Experiment includes 4 ROADMs:
-{{{
-roadm1-co1.cosmos-lab.org (10.104.1.1)
-roadm2-co1.cosmos-lab.org (10.104.1.2)
-roadm3-co1.cosmos-lab.org (10.104.1.3)
-roadm4-co1.cosmos-lab.org (10.104.1.4)
-}}}
-
-
-3 interfaces are connected to these servers from data1 pool of ToR interfaces:
-
-{{{
-twentyFiveGigE 1/1/1 <--> srv1-lg1.bed.cosmos-lab.org
-twentyFiveGigE 1/1/2 <--> srv2-lg1.bed.cosmos-lab.org
-twentyFiveGigE 1/1/3<--> srv3-lg1.bed.cosmos-lab.org
-}}}
-
-
-3 interfaces and 3 transceivers are associated with them in vlans:
-
-{{{
-vlan 121: twentyFiveGigE 1/1/1 ; tengigabitethernet 1/32/1;
-vlan 122: twentyFiveGigE 1/1/2;  tengigabitethernet 1/29/1;
-vlan 123: twentyFiveGigE 1/1/2;  tengigabitethernet 1/31/1;
-}}}
-
-
-We are assigning next wavelengths to tengigabitethernet:
-
-{{{
-1553,30 nm 193,00 with bandwidth ~[192.95;193.05] Thz
-}}}
+This 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".
+
+This experiment uses 3 servers and 4 ROADM units from the {{{bed.cosmos-lab.org}}} domain:
+{{{
+srv1-co1.bed, srv1-lg1.bed, srv2-lg1.bed
+rdm1-co1 (10.104.1.1), rdm2-co1 (10.104.1.2), rdm1-lg1 (10.104.2.1), rdm2-lg1 (10.104.2.2)
+}}}
+
+Setup for the ToR switches ({{{da-sw-co1}}} and {{{da-sw-lg1}}}), 10G DWDM tunable sfp+ transceivers, and vlan:
+{{{
+(da-sw-co1) vlan 1066: Eth 1/1/1:1 (srv1-co1 data1);  Eth 1/1/66 (10g dwdm tunable);
+(da-sw-lg1) vlan 1033: Eth 1/1/1:1 (srv1-lg1 data1);  Eth 1/1/33 (10g dwdm tunable);
+(da-sw-lg1) vlan 1034: Eth 1/1/1:2 (srv2-lg1 data1);  Eth 1/1/34 (10g dwdm tunable);
+}}}
