European Advanced Networking Test Center Carrier Ethernet Justification

Carrier Ethernet one of the hottest topics in wireline and wireless backhaul networking in 2006 Î Carriers seek for scalable and affordable solutions for Triple Play and business layer 2 services Î Many networks are upgraded after telecom investments were delayed in the early 2000‘s Î “Carrier Ethernet” driven by strong marketing efforts

European Advanced Networking Test Center Carrier Ethernet Defined

• Carrier Ethernet is a ubiquitous, standardized, carrier-class SERVICE defined by five attributes that distinguish Carrier Ethernet Carrier from familiar LAN based Ethernet Ethernet • It brings the compelling business benefit of the Ethernet cost model to achieve significant savings

• Standardized Services

• Scalability Carrier Ethernet • Service Management Attributes • Reliability

European Advanced Networking Test Center Performance Tests

Carrier Ethernet imposes new scalability, performance, security challenges Typical issues: ¾ Cannot learn Ethernet addresses fast enough ¾ MAC address table too small ¾ Does not master MAC flooding and hijacking attacks ¾ Throughput depends on % of mcast/bcast traffic ¾ QoS implementations not easy to configure, different philosophies / hardware support ¾ …

European Advanced Networking Test Center Outlook

¾ Carrier Ethernet has a great future because it is a service-based idea – not limited to Ethernet transport

¾ Stringent Network-Network Interface (NNI) specifications are required to achieve performance and interoperability goals

¾ Further scalability, protection and multicast testing required in the future
