The mass deployment of fiber access networks is probably the most important network upgrade strategy for operators over the coming decade. Next-generation networks, and in particular the long-reach passive optical network (LR-PON) solution, aim to increase the long-term economic viability and sustainability of fiber-to-the-premises (FTTP) deployment. The(More)
10-Gigabit-capable Passive Optical Network (XG-PON), one of the latest standards of optical access networks, is regarded as one of the key technologies for future Internet access networks. In this paper, we propose and discuss the design and implementation of an XG-PON module for the NS-3 network simulator. The aim is to provide a standards-compliant,(More)
Long-reach passive optical networks (LR-PONs) prove to be a suitable candidate for future broadband access networks. The longer reach of the feeder fiber in a LR-PON enables us to consolidate a large number of end users. The longer reach also eliminates a degree of electronic processing by eliminating the metro network and connecting the local exchanges (or(More)
The increasing success of Video on Demand and IPTV services poses several challenges to both network operators and service providers. Due to their heavy bandwidth requirement and the high concentration of requests during peak times, implementing these services efficiently without compromising the Quality of Experience of customers is not a trivial task.(More)
 One of the major side effects of radical radiation therapy for head and neck malignancies is xerostomia, or dryness of the mouth. There is no clearly effective treatment for this condition, but we have observed that patients in our practice believe that their symptoms improve significantly when using two "over-the-counter" oral comfort products – Biotene(More)
Content Distribution currently accounts for the vast majority of Internet traffic. Peer-to-Peer represents a scalable and inexpensive strategy to deliver content to end-customers; unfortunately, it poses a sever strain on the network core and generates high costs for service providers. Locality-aware policies have been proposed to tackle these issues, but(More)
Fibre-to-the-premises (FTTP) has been long sought as the ultimate solution to satisfy the demand for broadband access in the foreseeable future, and offer distance-independent data rate within access network reach. However, currently deployed FTTP networks have in most cases only replaced the transmission medium, without improving the overall architecture,(More)
Thirty-one patients with stage IIIA (N2) non-small-cell lung cancer were randomized to receive radiotherapy alone or chemotherapy with cisplatin and vinblastine followed by surgery. Response rates to induction chemotherapy and radiotherapy were 50% and 53.3% respectively. Complete surgical resection was possible for 62.5% of patients. Median survival times(More)
Backhauling base stations with Passive Optical Networks (PONs) besides bringing a new revenue source for the PON operator, can reduce the cost of installing new base stations for the mobile operator since a new, dedicated, backhaul can be avoided. If mobile operators have more than one base station on the PON, they might be interested in assuring bandwidth(More)
