The emerging Ethernet technologies deployed in metro networks provide services based on pure Ethernet. Low cost optical Ethernet interfaces are used to interconnect different sites. Then, the use of wavelength division multiplexing technology with optical Ethernet is clearly the next step in building cost efficient metro networks. In this paper we propose a novel architecture and configuration methods...
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...
This paper introduces a novel dynamic availability-aware survivable routing architecture in the modern communication networks, which aims to provide much finer design granularity by having a partially restorative protection path for a working path. Simulation is conducted to verify the proposed scheme on a special case where a single protection path is equipped to each working path, where an integer...
