Photonic MPLS router to create bandwidth-abundant IP networks

Experimental Investigation of Adaptive Ethernet Forwarding and Optical Cut-through for Metro Optical Ethernet Networks

“…Compared to normal Ethernet or WDM networks, the benefits of iOPEN are numerous: 1) Increasing processing capacity of traffic by using optical cut-through; 2) Supporting QoS and traffic engineering with dynamic topology changes to adapt to traffic conditions; and 3) Simplifying management and reducing operation cost. Though hybrid IP packet and WDM networks have been extensively studied and demonstrated in recent years [5]- [7], to the best of our knowledge, we do not see any experimental results or demonstrations of direct integration of Ethernet with WDM without IP layer. In hybrid IP packet and WDM networks, it is relatively easy for packet or traffic to choose either IP forwarding or WDM switching by using some QoS and traffic engineering measures or manually configuring routing tables.…”

Experimental Study of a Novel Cross-Layer Traffic Optimization Technique for Improving Throughput in Metro Ethernet/WDM Networks

“…Initially, all the traffic will use the route of Ethernet forwarding by assigning ports for cut-through a VLAN different from the VLAN used for Ethernet forwarding [4]. (VLAN 1 is a default VLAN assigned to all ports when system boots up [5]). For example, we make port 1, 2, and 3 work on VLAN 2 and Port 4 work on VLAN 4.…”

GMPLS Based Survivable Photonic Network Architecture

“…The recent prevalence of broadband access services such as Asymmetric Digital Subscriber Line (ADSL) or Fiber to the Home (FTTH) service requires a wide bandwidth for optical backbone networks. Thanks to the maturity of optical component device technologies such as optical amplifiers, wavelength multiplexers or de-multiplexers, and optical switching devices, the nationwide deployment of reconfigurable optical add/drop multiplexers (ROADMs) and optical crossconnects (OXCs) [1] is fast becoming a feasible solution for network operators to meet the recent intensive traffic demand. In ROADM/OXC networks, Operation, Administration, and Maintenance (OA&M) functionality is achieved through the ITU-T G.872 based optical transport network (OTN) architecture [2], which employs a three-layer architecture.…”
