XV Virtual Machine

Enhance user experience and network efficiency while securely scaling hybrid networks

XipLink technology delivers the most advanced satellite and wireless optimization, assuring the best possible ‘goodput’ at a reasonable cost. The technology has been perfected over decades of intense and dedicated focus in the Wireless Link Optimization environment and includes multiple mechanisms that operate at several layers of the networking stack.

The XipLink Optimization Software (XipOS) can be provided as a software virtual network function (XV prefix) that scales from 1,000 to 300,000 TCP sessions on a desktop or 1U platform. Aggregate throughput beyond 2Gbit/s is delivered via a highly-scalable virtualized blade server. XipOS software is deployed as a virtual function and is remotely managed using a user-friendly Graphical User Interface or can be centrally managed via XipLink central management software (XMS). 

Conveniently integrated hardware appliances are available for projects where no Edge CPE is available. These appliances are identified by the XA prefix. XipLink also provides high speed, fully integrated appliances for deployment to satellite ground stations or hybrid cloud environments.

All major VM hypervisor systems are supported KVM/QEMU and VMWare ESXi or Player.

XipOS Software Features

User Experience

TCP Acceleration using the SCPS-TP standard, scalable TCP up to 1Gbit/s per XV image, fast start, congestion controls, acknowledgment frequency reduction, selective negative acknowledgement, DNS caching

Optimization Features

Packet Coalescing with Header Compression, Stream Compression, Byte Caching

Transparent Tunnel Acceleration

Accelerate TCP embedded in tunnel technologies: Transparent GTP (4G and 5G), GRE, VLAN, MPLS and XipLink Lightweight Tunnels (XLT)

Layer 2 Support

Layer 2 over Layer 3 (VXLAN) and VLAN Tagging

Traffic Steering with Link Balancing & Bonding

OverSite traffic steering policies steer and overflow unique groups of traffic onto one or more links, based on link status, protocol, IP source and destination address and subnets, port numbers, DSCP mark, VLAN ID, VLAN priority and MPLS label. Links are actively monitored for congestion and buffer bloat. Sessions are smoothly moved to alternate links, within seconds of a link degradation or failure. Bandwidth Bonding uses the available bandwidth of all links, for any IP traffic, including UDP and TCP/IP.

Advanced QoS

Class based weighted fair queuing (CBWFQ), Min/Max/Guaranteed Bandwidth setting, Bandwidth Pooling, Allow/Deny, Selective Optimization


VPN / IPsec, Pre-Shared Secrets, X509 Certificates, CMPv2, IPsec Decrypt-Optimize-Encrypt (DOE) supports acceleration of encrypted traffic
