XStream IP modem TCP acceleration extended to cover new protocols

January 17, 2018

Paradise’s XStream IP™ advanced modem IP optimization suite has been extended to include the acceleration of Server Messenger Block (SMB V2 and V3) and Common Internet File System (CIFS) protocols. These are used for file sharing via remote server access, as used for example in cloud applications. SMB/CIFS are inherently extremely inefficient when used over high latency satellite links because all file accesses are broken down into sequences of operations that need to be completed serially, resulting in large delays due to multiple satellite round trips.


Our SMB/CIFS proxy sits between the client and server and optimises remote file accesses, minimizing the number of round trips required to satisfy requests and thereby minimizing the time taken for data retrieval and saving files on the server. It does this using a variety of techniques such as caching data and reading/writing files in larger chunks than would otherwise be the case.


The XStream IP™ embedded IP optimization suite includes TCP and HTTP acceleration, header and payload compression, traffic shaping, encryption, packet encapsulation and ACM and VCM.


XStream IP™ has also recently been expanded to include TCP Cipher Acceleration hardware that, in addition to providing general purpose TCP acceleration, is able to accelerate traffic from IP crypto devices. To achieve the highest possible performance, the initial release of SMB and CIFS acceleration runs on the high power TCP Cipher Acceleration hardware modem add-on card. At a later date, a lower cost solution will be available when the new protocol acceleration is migrated to run directly on the modem main processor.
