Expected-Capacity Guaranteed Routing toward Reliable Access-Metro Edge Computing
Access-Metro Edge Computing
Expected-Capacity Guaranteed Routing
Expected-capacity guaranteed routing (ECGR) is the routing
and capacity allocation method that guarantees the expected
value of the allocated capacity based on link failure prediction
Required Capacity: 100 Gbps
45 Gbps * 0.9 = 40.5 Gbps
25 Gbps * 0.8 = 20.0 Gbps
45 Gbps * 0.9 = 40.5 Gbps
SUM
101 Gbps > 100Gbps
Multipath routing saves bandwidth resources.
Guaranteed expected capacity gives high reliability.

Access-Metro Edge Computing treats processing modules of
network devices in network as edge computing resource. It
enable expansion of resource and flexible resource assignment.

The software routers can accommodate traffic of any
applications, but because multipath forwarding provides
high throughput, they are suit for stored data transmission.
