Switch fabrics for 100 Gigabit Ethernet systems pose high demands in terms of delay and scalability. In this paper we analyze the performance of a Clos-based switch fabric under uniform and bursty traffic, and compare its performance to a crossbar-based switch design for benchmarking. In particular, we focus on a Clos-design using a Space-Memory-Memory (SMM) configuration, which has recently gained...
This paper addresses network survivability for IPTV multicast transport in Carrier Ethernet networks. The impact of link failures is investigated and suggestions for intelligent multicast resilience schemes are proposed. In particular, functions of the multicast tree are integrated with the Carrier Ethernet transport layer, thereby optimizing the protection path with regards to delay and Quality of...
The Internet users behavioural patterns are migrating towards bandwidth-intensive applications, which require a corresponding capacity extension. The emerging 100 Gigabit Ethernet (GE) technology is a promising candidate for providing a ten-fold increase of todays available Internet transmission rate. As the need for 100 Gigabit Ethernet equipment rises, so does the need for equipment, which can properly...
