As multimedia communications are developing rapidly in Internet, in order to improve the end-to-end (E2E) performance, we propose an overlay routing layer middleware (ORLM) aiming to overcome the limit inherent in the Internet’s IP-layer routing service with the aid of a cross-layer design, based on the ALTO service and the NGI QoS support. In this paper, we mainly show the design principles and details...
EPS including Long Term Evolved (LTE) and Evolved Packet Core (EPC) has been accepted as the architecture of the next generation advanced mobile telecommunication network in the future. QoS in EPC is an important mechanism to provide guaranteed service to users. However, current QoS in EPC mainly based on barrier identification, resulting in complicated and forgetful QoS negotiation and updating process...
IPv6 has gained its common sense as a fundamental IP instruction for the next generation network with larger address space with better QoS (Quality of Service) service. The IPv6 FL (flow label) is a function that, as it was designed, can be a big help in alleviating QoS problem from flow level treatment. However, the original design of FL can easily induce scalability problem and it has not been used...
In the past few years, overlay networks have emerged as an alternative option for supporting value-added services such as fault tolerance, multicasting, and security. In this paper, we describe a quality of service (QoS) overlay network architecture for scalable, efficient and practical QoS support. In this architecture, we propose a flow label (FL)-based QoS class mapping method for QoS implementation,...
In order to support more value-added services and a larger space for IP addresses, the Internet requries to classify IPv6 packets into flows for specific requirements. High performance IPv6 packet classification (PC) algorithms are therefore in high demand. This paper proposes a new IPv6 PC algorithm based on flow label (FL), called FLIN (Flow Label Initial Noticed). FLIN is fast and scalable with...
The emergence of new types of popular multimedia services requires in the long run a quality-of-service (QoS) solution better than the best-effort service provided by IP. Failure to widely deploy either one of the main architectures for IP QoS, integrated services (IntServ) or differentiated services (DiffServ), has fueled research into alternate solutions. Therefore, an alternative approach for QoS...
The next generation Internet Protocol, IPv6, has attracted growing attention and has been deploying worldwide, especially in Europe, Asia, and North America. It intends to provide better QoS (quality of service) ability for the increasing demanding multimedia service, and FL (flowlabel) field in IPv6 main header was designed to be a big help in alleviating QoS problem. However, the related research...
