A lot of attention is being paid to overcoming a number of present Internet limitations, mainly w.r.t. mobility, security, address space exhaustion, and routing table size growth. The continuous patching of the TCP/IP suite with ad-hoc protocol extensions and overlay solutions is regarded as a complex and costly solution in the long term. As a consequence, the so-called “cleanslate” approach to...

Forwarding accountability mechanisms pinpoint the sending/forwarding properties of traffic to the entities that send and forward the traffic along a path. In this paper, we take flooding attacks as a use case and describe a proposal to hold senders accountable for the sending rates of their flows. Furthermore, we describe the corresponding challenges, potential solutions, and briefly present th...

In addressing the integration of IP and WDM networks, we propose a joint operation approach. Through reconfiguration or real-time setup of lightpaths, joint operation focuses on optimizing network performance or guaranteeing it to a defined level under current network configuration and dynamic data traffic pattern at the network operational stage. Our model features a separation of control plan...
