Standards Engineering 7 Next Generation Networks Current networks - opaque and static Next generation networks - agile (flexible) and transparent Agile = dynamically reconfigurable Current networks - opaque and static Next generation networks - agile (flexible) and transparent Agile = dynamically reconfigurable

Standards Engineering 8 Enabling Agile Transparency Products needed to enable agile transparency: –Optical transport technology that extends the distance between optical to electronic conversions –Optical switching technology that adds little cost or signal degradation to through traffic Many companies working on such products Products needed to enable agile transparency: –Optical transport technology that extends the distance between optical to electronic conversions –Optical switching technology that adds little cost or signal degradation to through traffic Many companies working on such products

Standards Engineering 9 Dynamic Modules An important class of products are not currently being addressed in IEC TC86 Differentiating features : –alter and control the inter-relationship of channels in a multi- channel device. –provide flexible connectivity or conditioning, rather than being fixed (i.e. dynamic not static). Some elements span across subgroups in IEC TC86 Agreed to form a new group under TC86 called “Dynamic Modules” (TC86 WG8) An important class of products are not currently being addressed in IEC TC86 Differentiating features : –alter and control the inter-relationship of channels in a multi- channel device. –provide flexible connectivity or conditioning, rather than being fixed (i.e. dynamic not static).
