    Traffic between the IP gateway and the intranet host uses a standard IP packet format. However, the IP gateway implements an Hughes-proprietary protocol between itself and the satellite routers that is optimized for efficient, yet reliable communication over the satellite link.

    profiles. Profiles are generally organized by function or feature, and can be of two types: shared and unique. • Shared profiles can contain such parameters as resource allocations and tuning parameters, which are often shareable. Operators can create shared profiles and manage them independently of any particular network component.

  • Page 43: Fault Management

    Vision monitors the status of gateway and remote site network components through simple network management protocol (SNMP) and proprietary Hughes protocols. All managed HX network components have embedded SNMP agents that can report status and statistics information to a suitably configured SNMP manager.

  • Page 44: Performance Management

    Performance NMSS provides both real-time and historical statistics on network components and traffic. These statistics are obtained by management querying components through SNMP. Real-time statistics Real-time performance reports are shown through the Vision UEM GUI. Detailed statistics, which are updated periodically, can be displayed on every managed network component.

  • Page 45: Management Nmds

    Partitioning is performed at the network device (satellite router or HX gateway component) level. When a network is installed, one NMD, called the default NMD, is automatically provided. Each device belongs to exactly one NMD. Management NMDs To limit the number of service offerings that must be managed and maintained, all value-added resellers (VARs) are presented with the same set of service offerings (and therefore, profile groups).

  • Page 51: Bandwidth Management

    The Hughes HX System allows the return channel burst size to be built optimally per satellite router, based on demand. Extensive and repeated tests on the throughput of the Hughes inbound system demonstrate inbound efficiency up to 85 percent.

  • Page 52: Bandwidth Assignments

    Inroute bandwidth To leverage the fact that all satellite routers within the HX System are fully frequency-agile across all inbound channels, the HX pooling System bundles the inbound channels into a single large pool of resources.
  • Page 53 Figure 5: Multi-frequency inbound access To achieve the efficiencies of pooling (that is, to realize the effects of the law of large numbers) while, at the same, providing the quality of service committed for each satellite router, the HX System uses a number of techniques. One important element is the concept of inroute quality of service (IQoS) plans.

  • Page 54: Dynamic Stream Services

    The advantage of guaranteeing bandwidth is that when an IQoS plan does not fully utilize its assigned bandwidth, the HX System is free to reallocate this bandwidth to other IQoS plans (allowing over subscription of bandwidth), providing flexibility to an operator.

  • Page 55: Advanced Bandwidth Management Techniques

    Advanced bandwidth The HX System has advanced bandwidth management tools that advise the operator how much outbound and inbound bandwidth management has been consumed by various CBR and CIR services, as well as techniques how much bandwidth is available for the best effort services.
  • Page 56 • Step increment – The fixed amount of bandwidth, in kbps, that will be allocated to a satellite router as it requires more than the minimum CBR amount. The HX System uses the threshold level (defined above) to determine when to allocate additional step increments.

    in the allocated bandwidth. The decrease amount is dictated by step-size. • Session activity timeout – The period of IP inactivity after which the session will be disconnected and the bandwidth freed for use by other satellite routers. Note: The idle timeout feature can be disabled in order to configure nailed-up bandwidth assignment.

  • Page 58: Outroute Cir

    Figure 8: CIR services with best effort Figure 8 illustrates the CIR with best effort service. In this access mode, the satellite router is provided the guaranteed CIR the moment traffic activity is detected. A satellite router is eligible to receive bandwidth in excess of its guaranteed CIR up to its maximum CIR based upon its advertised backlog, periodic, and left-over bandwidth.

  • Page 59: Best Effort Services

    The IQoS plan defines the maximum amount of bandwidth available to a group of satellite routers as they access the dynamic stream bandwidth. The HX System supports multiple IQoS plans, allowing operators to provide different levels of best effort services to different groups of customers.
  • Page 60 In the outroute direction, traffic prioritization occurs in the soft QoS before the hard QoS. The HX System can prioritize both inbound and outbound traffic (Figure 9) based on IP parameters. This prioritization can be based on either source or destination IP address and/or IP port numbers and Diffserv code point bits.

  • Page 61: Unlimited Combination Of Service Plans

    Unlimited combination Because the HX System treats the inbound channels as a pool, and given that inbound TDMA bursts are of variable lengths, the of service plans HX System can efficiently provision a virtually unlimited combination of service plans. This contrasts significantly with...

    • TCP /UDP port number • Diffserv code point (DSCP) bits NAT/PAT HX System satellite routers support network address translation (NAT) and port address translation (PAT), allowing translation of IP addresses from the local LAN to global or external addresses.

  • Page 66: Port Mapping

    The capability for NAT and PAT is assigned to satellite routers in their profiles, assigned to them at the HX gateway. The following NAT/PAT modes are supported: • Port Address Translation (PAT) allows users to send data traffic from multiple IP devices on the satellite router LAN using a single address.

    address, from an enterprise DHCP server. DHCP requests received by a satellite router from devices on a connected LAN are forwarded through the spacelink to the HX gateway, which in turn, forwards them to an enterprise DHCP server. The responses are carried over the spacelink to the satellite router and sent out on the LAN port from which the requests were received.

  • Page 69: Vrrp

    VRRP VRRP provides redundant internet gateways. Increased availability is achieved by creating a virtual router consisting of a group of cooperating physical routers that share a MAC and IP address. The physical routers elect and monitor a master router to service requests.
