A single-ended optimized storage protocol enables storage clients or other devices to direct a remote data storage to copy data. In response to commands via the protocol, a remote data storage can copy portions of a data stream at the remote data storage to destination storage locations within the same or a different data stream. The protocol may be utilized for optimized transfer of data via a network to a remote data storage. An initial data stream is divided into segments. Redundant segments are removed from the data stream to form an optimized data stream, which is transferred to the remote data storage. Commands are issued to the remote data storage using the protocol to direct the remote data storage to reconstruct the initial data stream at the remote data storage using the optimized data stream and optionally segments from other data streams previously transferred to the remote data storage.

Single-ended deduplication using cloud storage protocol

Digital certificates are distributed to WAN optimization modules in organization and content delivery networks to securely optimize network traffic. The content delivery network identifies edge WAN optimization modules for use with each combination of organizations and their cloud services and distributes digital certificates accordingly. Peering digital certificates for establishing inner connections between organization and edge WAN optimization modules are exchanged via one or more management portals. Shadow digital certificates for establishing outer connections between WAN optimization modules and clients are generated in the form of certificate signing requests. Configuration information identifies any additional cloud services associated with a given cloud service and generate corresponding additional certificate signing requests. Certificate signing requests are digitally signed by a certificate signing authority associated with the organization and then returned via the one or more management portals to the allocated edge WAN optimization modules. Digital certificates may be rotated for security purposes.

Managing digital certificates for WAN optimization over content delivery networks

WAN optimization devices and content delivery networks together optimize network traffic on both private networks and public WANs such as the internet. A WAN optimization device intercepts and optimizes network traffic from clients within a private network. The WAN optimization device communicates this first optimized network traffic to the nearest edge computer in the content delivery network via a public WAN, such as the internet. This edge computer further optimizes the network traffic and communicates the doubly optimized network traffic via the content delivery network to a second edge computer nearest to the network traffic destination. The second edge computer converts the doubly optimized network traffic back to its original format and communicates the reconstructed network traffic from the second edge computer to the destination via a public WAN. Licensing and configuration portals configure WAN optimization devices for specific network protocols, types of network traffic, applications, and/or cloud services.
