4 Background of the sof ware defined networking and its c ntrol pla e for

optical nodes

Optical network are evolvin from static l n services to flexible ln services to provide

future dy amic tran p rt services Sof ware defined networkin (SDN) is one of the network

arc itectures that ena le flexible an d namic network control The b sic ide of SDN is to

se arate the control plane from the data plane, al owin con oldation of hardware

infrastru ture to save the overhe d as ociated with p r-service de loyment of a closed set of

resources s c as computation, storage, an network For o tical y switc ed network s c

s heme s ould b desig ed to b as simple as p s ible, as they as ociate with complex

config ration of multiple d namic mod les In p rtic lar, common control interface is a key

for re l zin the control plane for s c an o tical y switc ed node; th s, these interfaces

s ould b pro erly defined from not only the sofware, but also the hardware asp ct Su h an

interface ena les q ic network bui din without hardware restriction

There are several kin s of hig -p rforman e node s stems for recent hig -sp ed

commu ication s stems, s c as the internet protocol (IP) router in the field of data

commu ication an the reconfig ra le o tical ad -dro multiplexin (ROADM) s stem in

therefore, the neces ary commu ication ca acity for the control plane network is pre ared In

6.1 De cription of the c ntrol er

6.1.1 Control er of multiple dy amic module for a network no e

For config rin a sin le network node as a hig -p rforman e node s stem, the control p rt

s ould b a sin le interface to the network control plane The control interface is a network

control er that u ifies multiple d namic mod les with variou hardware/sofware comp nents

to make it b have as a sin le network node This con e t helps in bui din up the o tical

network s stem in a way that simpl fies the entire hardware config ration Fig re 1 s ows a

con e tual bloc of the control interface for multiple d namic mod les an network devices

From a network config ration p int of view, thre layers ( he a plcation layer, control layer,

an infrastru ture layer) work as a co rdinated network A large amou t of commu ication

eq ipment, s c as o tical tran p rt s stems, is distributed in the infrastru ture layer, an

s stem config ration in the infrastru ture layer has an imp ct on the adjacent layer The

intermediate control er has the role of wra pin up several network devices an d namic

mod les in the s stem Th s, the intermediate controler provides a simpl fied commu ication

en ironment to the s stem, an it can b a wra -up control p rt of the hig -p rforman e node
