Optical Ring Networks

1
Optical Ring Networks

• Research over MAC protocols for optical ring
  networks with packet switching.
• MAC protocols divide the ring bandwidth according
  to rules established by fairness policies.

2
Optical Ring Networks

• Data flows in the ring are composed in great part
  by TCP traffic.
• It is important to analyze the impact of ring MAC
  protocols over TCP connections.

3
Optical Ring Networks

• Current protocols offer fairness based on
  throughput of nodes or flows.
• Bandwidth is assigned regardless of the number of
  users in the flows.
• Result unfairness from the users point of view.

4
Optical Ring Networks

• Creation of new MAC protocols for optical ring
  networks.
• Protocol capable of sharing the ring bandwidth
  with fairness among TCP connections.
