Satellite IP solutions
Internet access and network interconnections are now essential to all of us. Every company, every institution, and increasingly, every individual, needs to be connected. There is a range of technologies available on the market, of which satellite is one of the most reliable (with 99.95% availability). When satellite is the chosen solution, there are a number of issues that need to be addressed:
Performance: the high latency on satellite networks (~700ms), as well as inefficient transport protocols, inefficient applications, and usually shared bandwidth, lead to a decrease in the productivity of remote networks connected to the Internet/Intranet via satellite. Even when the bandwidth is increased, some applications continue to perform slowly and so provide unsatisfactory work results.
UDcast brings high performance to satellite IP communications, effectively closing the gap with terrestrial access technologies, such as DSL. More importantly, UDcast enables satellite communications to function using full IP networking, while optimizing bandwidth utilization. UDcast uses TCP acceleration and state-of-the-art compression/caching mechanisms, and has developed specific application acceleration, like http and CIFS. The objective is to provide a wide range of highly advanced features that enable service providers and end users to get the most out of their satellite IP links.
Bandwidth: the cost of bandwidth dramatically affects the OPEX of satellite IP networks. Until now, terrestrial ADSL connections have been preferred because of their considerably lower cost than connections over satellite. Satellite bandwidth is the key issue in the SSP business model. The huge bandwidth savings provided by the UDgateway allow the SSP to add more users within the same amount of bandwidth, resulting in more competitive prices that are very similar to those of DSL connections.
Security: security is increasingly important for enterprise networks and government projects, which want to obtain the same level of security as they would if the remote networks where physically located at their headquarters. As data is transmitted over the air, an encryption mechanism is necessary to ensure the required level of security. UDcast’s solutions bring unparalleled end-to-end security to satellite IP communications. Based on the IPsec standard, they are fully transparent and entirely manageable by the enterprise, while still accelerating all applications.
UDcast’s satellite IP solutions address the above issues so that satellite service providers can offer LAN-like services, and end users are able to forget that they are connected to the Internet through a satellite network. The benefits are listed in the chart below, and include amortization of the equipment in only a few months.
| Benefits for Satellite Service Providers | Benefits for End-users |
|---|---|
|
Bandwidth savings: beams may be less charged, enabling more remotes to be added within the same beam. Professional service offered for companies and government projects. Increased customer satisfaction. Less hotline calls. Win bids where end-to-end security is a must.  |
Increase in employee productivity. Traffic differentiation: allows critical applications to be prioritized versus other applications. Secure networks end-to-end based on standards. Bandwidth savings: increased performance using less bandwidth. Data centre consolidation: most servers located at headquarters (i.e., e-mail, Windows server, SAP, etc.). Only feasible when acceleration is provided. CAPEX savings (UDgateway as all-in-one solution): VPN, router, firewall, antivirus, acceleration and QoS integrated. Less equipment to maintain and manage. |
KEY APPLICATIONS
Geographically Dispersed Enterprises
The need for competitive differentiators leads to companies being strategically distributed in various branch offices connected to headquarters. The reasons for this are so that they can be closer to their customers in each location, get access to cheaper manpower, and be present in strategic places, etc. Enterprises are, by definition, decentralized. But they are still part of the same company, and the same network.
For these remote, satellite-connected networks to function in a LAN-like environment, a solution must be found for accelerating all applications and securing the link from the remote networks to the company’s headquarters. UDcast’s solutions have been implemented for hundreds of companies, including oil and petrol businesses, banks and construction companies.
Business Continuity
UDcast understands the value of maintaining IP communications. Its solutions help to protect enterprise and government organizations against loss of revenues, service degradation and other damages to their activities when failures occur in the traditional terrestrial infrastructure.
Disaster Recovery
Re-establishing reliable IP communication is among the very first steps of any major disaster recovery plan. UDcast's solutions help to ensure that both voice and data communications operate at their peak efficiency in areas impacted by any type of natural or man-made incident.
Bridging the Digital Divide
UDcast's satellite performance technology enables enhanced delivery of IP communication services anywhere, anytime. It can be deployed immediately and with no investments into costly terrestrial infrastructure. Bridging the digital divide is essential for the growth of broadband usage in rural areas and for the emergence of developing economies in all the parts of world.
