Consumers and enterprises will benefit in terms of high bandwidth and flexibility.
Carrier-grade Ethernet in the first mile means an increased reach with speeds of 10 to 100Mbit/s in metropolitan and also more dispersed residential areas.
Enterprises, on the other hand, are looking for flexible service offers ranging from the replacement of E1/T1 lines to Gigabit Ethernet multipoint-to-multipoint services.
This can be achieved through the use of direct fibre connections, although the latest DSL technologies like VDSL and ADSL2+ also permit distances of up to 6km or speeds up to 100Mbit/s.
In the second mile, traffic is aggregated toward an IP/MPLS core for services such as residential high-speed internet access.
For services like LAN interconnection, VPN, peer-to-peer traffic, video on demand or TV broadcast, direct connectivity is provided.
A structured network and service architecture maps this variety onto a simple generic model.
This concept is implemented using VLAN and MPLS technologies, allowing a separation for security and service control, and the flexible provisioning of QoS and SLAs.
With advanced mechanisms for ring protection (ERP, RPR) and MPLS fast failovers, sub-50ms restoration times are possible.
Together with redundant nodes and network design, hitless switchovers and in-service upgrades, the required level of service availability can be guaranteed.
The presentation will be held on Wednesday 22nd September, 2004, at 1515 local time in the Palazzo dell'ex Casino (TecPreview Theater).
