A server system may include a plurality of internal hubs communicatively coupled to a plurality of server nodes. The plurality of internal hubs may communicate with an external hub to transmit broadcast traffic to reach a designated server node. A hub controller, a routing device coupled to the plurality of internal hubs, may select an internal hub from among a plurality of internal hubs based on a link status and a set of hub selection rules. Based on a status of active link and a relative priority of internal hubs, an internal hub is selected as a transmission channel to receive broadcast traffic from the external hub and direct the broadcast traffic to a corresponding server node.

A network system is provided between at least a first client site and a second client site, the first and the second client site are at a distance from one another. A client site network component is implemented at least at the first client site, the client site network component bonding or aggregating one or more diverse network connections so as to configure a bonded/aggregated connection that has increased throughput. At least one network server component may be configured to connect to the client site network component using the bonded/aggregated connection. A cloud network controller may be configured to manage the data traffic and a virtual edge providing transparent lower-link encryption for the bonded/aggregated connection between the client site network component and the network server component.

Certain aspects of the present disclosure generally relate to wireless communications and more specifically to a method for machine type communications involving identifying one or more subframes, within at least one radio frame, unavailable for bundled transmissions across multiple subframes and communicating, via at least one narrowband region within a wider system bandwidth, using bundled transmissions across multiple subframes based on the identification.
