Portabella is a packet-level load balancing 3G 4G LTE router. Portabella can bond cellular Internet access lines for all types of traffic (including encrypted traffic such as VPN) for aggregated downlink and uplink capacity when peered over the Internet with a Mushroom Relay located at the headquarter office or data center. The optional Broadband Bonding Service subscription enables downlink/uplink bonding.

Without peering, all HTTP downlink sessions are still bonded for faster file transfers. Even in cases of single HTTP session (such as a single file download), all Internet access lines are simultaneously and intelligently combined together to provide a faster data transfer for that single session.

Without the optional peering, non-HTTP downlink sessions and all uplink sessions initiated from the Local Network, will be session based load balanced intelligently across the 3G 4G LTE WAN lines. The application and cookie semantics will be preserved for sites such as banking sites.
