Regardless of what your business is, whichever industry you are operating in, if your business requires broadband connectivity for remote locations, SuperDirect is the ideal solution to provide end to end IP networking capabilities. Whether you are an oil refinery, retail chain, hospital, bank, media outlet or any business needing fast, reliable, broadband communication, SuperDirect can connect you. SuperDirect service works on the iDirect technology, which is the latest VSAT technology in the world.
SuperDirect system is a satellite based IP solution which is based on the iDirect platform. The service was launched in Q2 2007 and since then it has grown significantly. Supernet has a 5-IF Hub from iDirect which is capable of looking at five different satellites. Currently Supernet Ltd is offering SuperDirect services on two different Ku-Band satellites namely PAKSAT-1 and ABS from its teleport located in Karachi Pakistan. In both the cases the outroutes (Hub to remote carrier) are a using a maximum of 18 M bit/s each and there are multiple inroutes (Remote to Hub carrier) that support the customer traffic. Supernet customers include Airlines, Banks, United Nations organizations, cellular service providers, government departments, manufacturers, logistics companies etc.
SuperDirect uses the star topology, which consists of a Hub and multiple Remotes. The system is a 2 way broadband network solution with all traffic on the outroute or downstream broadcast over a TDM carrier. Remotes pass traffic to the Hub on a shared inroute carrier using Super Direct’s highly differentiated Deterministic TDMA (D TDMA) access scheme. The Super Direct system is ideally suited for networks with traffic patterns that follow a hub-to-spoke model and traffic that is bursty in nature. The system was designed and developed to optimize the transport of TCP/IP protocol traffic over satellite. The highly efficient D TDMA achieves efficiencies that are close to 98% of the payload bandwidth.
The SuperDirect system has features and controls that allow it to be easily configured to deliver application QoS and other traffic engineered solutions to the users. The SuperDirect system also provides TCP and Web acceleration that supports line rate TCP throughputs in BOTH directions, even to only one TCP session in the network. Other features of the system include optional 3-DES link encryption that encrypts the Remote, local DNS cache on the Remote, dynamic and static IP routing, end-to-end VLANs and mobile mode.
The highly scalable and flexible broadband Hub has been designed to support multiple outroutes and inroutes within a single Hub Chassis, while simultaneously enabling the connection of up to 5 different satellites. This architecture provides significant cost savings to the network operator, because they can support multiple footprints without incurring the cost associated with multiple Hubs.
SuperDirect is based on a platform that combines years of research and development in TDMA, satellite communications and software algorithm technology, resulting in the delivery of a unique combination of flexibility, reliability and cost-effectiveness. The features that have enhanced the SuperDirect solution include TCP/IP optimization over satellite (TCP and HTTP Acceleration, local DNS caching), QoS and Prioritization of traffic, traffic engineering flexibility options, DHCP/NAT, Network configuration and management features, centralized control features and MF-TDMA Frequency Hopping.
The SuperDirect remote consists of a 1.2m Ku-Band VSAT antenna, a PLL LNB and a 3000 or 5000 series satellite router from i-Direct.

Traffic Engineering
As different customers or different applications have different traffic characteristics, it is important for network operators to be able to design a network to support these requirements. The SuperDirect solution has traffic engineering features and capabilities that address layer 1 – layer 4 of the OSI stack. This tremendous flexibility and feature richness allows a network operator to design the most optimal solution to support any type of application.
Traffic engineering features include:
- Different Encoding Options
- Variable Frame Length (Support of realtime traffic and non-realtime traffic)
- Ability to change carrier size in 100 Hz range. Highly granular.
- Rate Limiting capability on a remote-by-remote basis.
- CIR or Committed Information Rate (Dynamic and Static) Capability
- VIR or Variable Information Rate Capability (Allows for burstability)
- QoS or Quality of Service. Class based queuing for prioritizing and allocating
- bandwidth for different types of traffic. This ensures mission critical
- applications bandwidth even during congestion times. Group QoS Support.
- Deterministic TDMA
