Abstract:

The introduction of new networking paradigms in optical networks has enabled new thinking with respect to network architectures and connection resiliency at both the optical and packet layers. Through the introduction of dynamic networking at the optical layer, technologies such as the IETF-defined GMPLS and architectures such as G.8080 (formerly G.ASON) defined within the ITU are enabling new options for closer synergy between the optical and packet layers of the network. This synergy is particularly relevant to the new capabilities enabled for diverse routing and connection protection.

This presentation will highlight some of the key values of packet/optical integration as they relate to services, connection management and protection. Topics include: the effects of new, flexible restoration techniques available with the advent of dynamically switched optical networks; the effects on packet technologies such as IP, MPLS and ATM; how packet /optical integration is complementary to emerging Optical VPN (OVPN).

Questions covered by this presentation include: What are the practical implications of applying these protocols to the optical domain? What networking architecture achieves this packet optical integration? What combinations of circuit based and packet based architecture make sense? This presentation tracks the current technology and standards as the new world of packet optical integration is described.
