Comparative Evaluation of Two Scalable QoS Architectures

This paper performs a comparative evaluation of two QoS architectures, RSVP Reservation Aggregation and Scalable ReservationBased QoS, aimed at providing QoS levels similar to the ones provided by the well-known RSVP/IntServ architecture, but scalable enough for use in high traffic core networks. The comparative analysis, based on each model’s characteristics and on simulation results, shows th...

Internet TV Architecture Based on Scalable Video Coding

The heterogeneity of the Internet raises several problems to the distribution of multimedia contents. This paper starts by introducing those problems and briefly overviewing the main approaches being used to mitigate them, in order to present a novel web-based Adaptive Video Streaming solution prototype, supporting Scalable Video Coding (SVC) techniques. The proposed solution, with focus on the...

SRBQ and RSVPRAgg: A Comparative Study

This paper presents a comparative evaluation of the Scalable ReservationBased QoS (SRBQ) and the RSVP Reservation Aggregation (RSVPRAgg) architectures, both designed to provide QoS levels similar to RSVP/IntServ without the scalability concerns that prevent its usage in high-speed core networks. The comparative analysis, based on simulation results, shows that SRBQ provides the same QoS guarant...

Scalable Reservation-Based QoS Architecture (SRBQ)

Having its roots in the military ARPANET, conceived as a data transport network with a focus on resilience, the Internet supports only a best-effort service model, where all packets are treated the same way, therefore providing a single level of service. Now that the Internet is becoming a ubiquitous global communication infrastructure, new applications are emerging with more demanding and dive...
