KDDI started deployment of the Telecom Infra Project's Distributed Disaggregated Backbone Routers (DDBR) as the Internet gateway peering routers.
KDDI estimates that DDBR carrying live internet traffic could reduce power consumption by about 46% and the rack space by about 40% compared to the traditional routers in KDDI production networks.
KDDI cites two key advantages for its DDBR architecture:
1. Optimal Merchant Silicon Selection and Configuration
Traditional routers comprise software, hardware and semiconductor chips chosen by one vendor. On the other hand, this DDBR comprises DriveNets Network Cloud software, hardware (40×100GE line card systems) from Delta Electronics, and merchant silicon (Jericho2) from Broadcom. Only one Jericho inside the hardware box has enough capability to fulfill software/hardware features and scalability in KDDI production networks. As a result, DDBR leads to reduce the power consumption, the equipment capital cost and the rack space.
2. Sharing of Hardware Resource
In a carrier's traditional network architecture, the dedicated routers for core, edge and internet GW are deployed depending on each area. On the other hand, DDBR can utilize the same white box hardware infrastructure for multiple areas such as core, edge and internet GW. As a result, it will enable KDDI to share hardware spare parts in our backbone networks, leading to the reduction of the equipment capital cost.
KDDI completed the DDBR technical requirements document in May 2021 and TIP announced the DDBR compliant vendors in March 2022. In March 2022, KDDI completed a final phase of commercial testing for DDBR.
