Abstract
To implement virtualized service-edge-routerfunctions on carrier networks using general-purpose servers, itis necessary to improve forwarding performance. The requiredforwarding performance of a service-edge-router reached morethan 100-Gbps in bandwidth on carrier networks.<br>In this paper, we propose a distributed architecture thatinvolves reconfigurable hardware accelerators with high-levelsynthesis technology for virtualized service-edge functions tosatisfy migration time constraints and improve forwardingperformance. The proposed architecture prepares severalcircuit files for the hardware accelerators according to theutilizations of the network functions in advance and selects asuitable circuit file at the time of migration, instead ofgenerating circuit files for the accelerators every time.<br>The evaluation of the proposed architecture showed thatmigration time can be almost the same as the time onconfigurations without hardware accelerators, and forwardingperformance can be on the order of 100-Gbps when ageneral-purpose server exhibits 10-Gbps forwardingperformance.
