High-speed routers rely on well-designed packet buffers that support multiple queuing, large capacity and short response times. Some researchers suggested a combined SRAM/DRAM hierarchical buffer architecture to meet these challenges. However, both the SRAM and DRAM need to maintain a large number of dynamic queues which is a real challenge in practice and limits the scalability of these approaches...
The future Internet is envisioned to host a large number of virtual networks managed by different operators sharing the same physical infrastructure. In such a scenario, an operator may not even own physical resources as such, but lease virtual resources to have their own virtual networks. While control-plane virtualization with several routing instances becomes common in equipments, the data plane...
In this work we investigate the effects of multiple access interference (MAI) and polarization mode dispersion (PMD) in optical code division multiplexing (OCDM) lightpaths. These paths are determined by the data encoding with non-coherent optical orthogonal codes (OOC), using a sequence inversion keying (SIK) optical correlator system. Our results show the impact of MAI effects and PMD constraint...
