Huawei IP OPS Components
Open Programmability System (OPS) is an open programmable ecosystem that can be deployed anywhere (embedded to
device, controller, collaboration-layer device, client or deployed independently) and consists of a series of components. It
implements multi-layer capability openness including network control and management. The OPS supports integration and
interconnection with third-party applications, implementing fast service innovation.
Just remember:
OPS is a powerful adhesive
and an integration tool for
agile networks. It can
effectively joint network
applications and the SDN
network.

Operating system
Through software-defined GRE tunnel between DCs, achieve rapid data
enter traffic scheduling virtual network. 21ViaNet DCI With this technique
bypasses the specified high cost, high risk traffic chokepoint, reduced
overhead while improving bandwidth utilization.
TE Tunnel
Agile TE APP :Flexibility to modify PW bear TE Tunnel
Through software-defined PW over TE tunnels quickly realized the
21ViaNet carries traffic scheduling multi-ring network, traffic priority to
identify and use, traffic protection, traffic operations quality assurance.
Improve the bandwidth utilization, to ensure that customers receive
quality service.
