We present a lab-trial of multi-domain path computation using a hierarchical PCE when domain topologies are aggregated as dynamic virtual meshes. We detail the extended path computation procedures, control plane extensions and the overall performance.
The LegOS (Lego Operating System) on top of an RCX system is an example of an operating system that enables infrared communication. Infrared communication is easy to implement in terms of hardware and software, but allowing three or more robots to participate in the communication is hard to accomplish through infrared techniques. This paper suggests a technique that allows communication among multiple...
This paper describes a new path computation model in Multi-protocol Label Switching (MPLS) and Generalized MPLS (GMPLS) networks. It introduces a path computation element (PCE), which is functionally separate from label switching routers (LSRs). The Path Computation Element (PCE) is an entity that is capable of computing a network path or route based on a network graph, and applying computational...
Within the generalized multi-protocol label switching (GMPLS), link management protocol (LMP) has been proposed to maintain the connectivity of the out-of-fiber control plane. In this paper, we analytically quantify the impact of control plane link failures on whole network performance. Then, we use the obtained results to suggest the keep-alive interval for LMP, introducing the least overhead to...
