Elastic Optical Network: A Promising Solution for Future Communication Networks Considering Differentiated CoS

“…So, the Internet traffic has been increased widely. Therefore, the Internet traffic is divided into three CoS [36]. These are CoS1-immediate service traffic such as video conferencing applications like Zoom, Skype, etc., CoS2-nonimmediate services such as compressed video, online game, video streaming apps like YouTube, Disney+, etc., and CoS3-delay permissive traffic services like bulk data file transfer.…”

Cost function‐based class of service provisioning strategy in elastic optical networks

“…Thus, it is important to classify the arriving traffic into differentiated class of service (CoS) 18,19 . The CoS is a method of managing multiple traffic over the network by indexing them as per their importance and urgency, which is defined in the service level agreement (SLA) policy in advance by the client 20 . Also, the CoS ensure that the highest CoS connection requests can be easily transported even when the network is suffering from congestion problem.…”

“…SLA policy is an agreement between the client and the network service provider in which the type of service, time constraints, service price, and negotiation policies are defined 16 . In this work, the traffic is classified into three different CoSs, that is, CoS1: real‐time traffic (i.e., online audio–video traffic), CoS2: nonreal‐time traffic (i.e., compressed video and transactional data traffic), and CoS3: delay‐tolerant traffic (like store‐and‐forward bulk data files transfer between various datacenters) 18–21 . The priority order of these CoS is as CoS1 > CoS2 > CoS3.…”
