Bandwidth Management in IntServ to DiffServ Mapping [chapter]

António Pereira, Edmundo Monteiro
2005 Lecture Notes in Computer Science  
This work presents a bandwidth management mechanism to be used with mapping mechanisms between Integrated Services (IntServ) and Differentiated Services (DiffServ) domains.  ...  The proposed bandwidth management mechanism evaluates the bandwidth needs of the AF classes in the DiffServ domain taking into account the behaviour of the previously mapped CL flows for the same IntServ  ...  The bandwidth management algorithm that supports the Admission Control functions in IntServ flows mapping into AF classes is described in Section 3.  ...

QoS Support for Real-Time Applications Using the Integration of RSVP/Intserv and Diffserv: A Testbed Experiment [chapter]

Seong-Ho Jeong, Myung Choi, Randal Abler, Henry Owen, John Copeland, Joachim Sokol
2000 Lecture Notes in Computer Science  
Recently, lots of attention is being paid to the integration of RSVP/Intserv and Diffserv because it can provide both end-to-end QoS and scalability.  ...  This paper presents a testbed realization of the integration of RSVP/Intserv and Diffserv to provide resource reservation and end-to-end QoS to real-time applications such as voice over IP.  ...  For seamless operations, requests in the Intserv region need to be mapped onto the underlying capabilities of the Diffserv region.  ...

Flow-Based Reservation Marking in MPLS Networks

N. Liu, J. Cao, M. Liu, J. Zeng
2008 2008 IEEE International Conference on Communications  
It provides a simple, scalable and adaptive mechanism of implementing quantitative end-to-end QoS by mapping per flow in IntServ into per class in DiffServ.  ...  Such marking based on traffic characteristics is irrespective to network dynamics, which causes collision and QoS degradation in DiffServ.  ...  ACKNOWLEDGMENT The authors would like to thank Shenyi Lin for proofreading the paper.  ...

Evaluation of end-to-end QoS support for mobile hosts in IPv6 with IEEE802.11e

Wei Wu, W.K.G. Seah
2003 2003 IEEE 58th Vehicular Technology Conference. VTC 2003-Fall (IEEE Cat. No.03CH37484)  
In this paper, we use IntServ at edge networks, DiffServ at core networks, and IEEE802.11e at the wireless last hop to provide end-to-end QoS for mobile hosts.  ...  IntServ and DiffServ are two architectures developed by the IETF to support Internet QoS.  ...  Therefore, GS service is mapped to EF service, CL service is mapped to AF service and BE service in IntServ is still BE service in DiffServ.  ...

Towards all-IP wireless networks: architectures and resource management mechanism

Majid Ghaderi, Raouf Boutaba
2007 International Journal of Wireless and Mobile Computing  
The first architecture, called ISB, is based on a combination of DiffServ and IntServ models appropriate for low-bandwidth 3G cellular networks with significant resource management capabilities.  ...  The second architecture, called DSB, is purely based on the DiffServ model targeted for high-bandwidth wireless LANs with little resource management capabilities.  ...  At the same time it must be able to handle the service mapping between different resource management models, i.e. the IntServ vs.  ...

Hybrid Technique for Enhancing Quality of Service in Wireless Network

Theophilus Alumona
2014 Advances in Networks  
in the wireless access segment of the network where the resources available and the levels of traffic aggregation render the DiffServ principles less effective, Integrated services (IntServ) provides  ...  fine-grained service guarantees to individual flows.  ...  It applies the DiffServ architecture and uses the IntServ management model. IntServ is not deployed here since its requirement of setting states in all routers along a path is not scalable.  ...
