Traffic replay tools that generate traffic in order to recreate real traffic scenarios play an important role in network operation. Nowadays, the Internet backbone links are increasing in capacity as well as in transmission speed making trace-based replay difficult. This paper proposes a novel approach to high-speed backbone traffic replaying. We bring out an original granular split of traffic that...
This paper examines the economic viability of two technologies - optical circuit-switched (OCS) networks and optical burst-switched (OBS) networks - in the core network. We analyze and dimension OCS network (OCSN) and OBS network (OBSN) architectures for a range of traffic demands given the constraints on the network element capacities. We investigate the effect of traffic grooming for both of these...
We investigate the optimal level of IP integration for the deployment of an automatically switched optical network (ASON). We design and analyze a national network delivering a high bandwidth access to every user, and investigate the capital cost of ASONs with IP routers. Based on this analysis, we show that an ASON with IP routers at the edge is more cost-effective than other alternatives.
