The modern, optical bore metro and particularly core networks consist of multiple layers, where multiple different networking technologies are stacked one over the other. In this paper we assume an IP/MPLS layer over an DWDM layer, both controlled jointly by one vertically integrated GMPLS control plane. To better utilize network resources, smaller, upper-layer traffic streams are multiplexed into...
Ethernet protocol is the most wide-spread protocol in the local area network (LAN) environment. It is cost effective, simple, and provides high speeds, exactly what is needed in the provider network. However, deployment in the provider network imposes carrier-grade requirements. Standardization bodies realized this, and they are extending its capabilities: QoS support and traffic management by 802...
With the spread of survivable network the existing quality of service (QoS) classes are required to be expanded with service availability and maintainability issues. By including them in the service level agreements (SLAs) new and more complex requirements of commercial applications can be guaranteed. In this paper, a uniform framework of extending all types of QoS definitions with service availability...
