Adaptive Coding and Modulation Benefits • Why ACM: • Enables each remote to operate at the most efficient coding and modulation (MODCOD) scheme based on local conditions • How iDirect’s ACM works: • Assesses link conditions at each remote based on: • Location within the satellite contour • Antenna size and RF performance • Clear sky or rain fade conditions • Determines highest MODCOD to maximize throughput at any given time • Adjusts MODCOD for each remote in real time • Evaluates against QoS profile • iDirect’s ACM benefits: • Increased data throughput and bandwidths savings • DVB-S2 design optimized to maximize ACM performance • Real-time ACM gain monitoring through NMS (iMonitor) • Ease of network configuration
Features of the Evolution X3 VSAT • Integrated router functionality • 10/100Mbps Ethernet • Console access via Ethernet & serial ports • Enhanced L-band interface • Extended Rx frequency range (950MHz - 2150MHz) • DiSEqC-ready & 10MHz reference for future low cost PLL LNBs • 100W PSU for BUCs to 3W with option for higher power BUCs • Protocols and traffic engineering • Extensive range of IP routing protocols (TCP, UDP, ACL, ICMP, IGMP, RIP Ver2, BGP, etc.) • Group QoS, application based QoS, CIR and bandwidth on demand • VLAN tagging • Minimum CIR, CIR (static and dynamic), rate limiting • Fully manageable by iVantage NMS • Upgradeable over-the-air
Evolution Line Cards • Supports DVB-S2/ACM • Two GigE interfaces • Hot swappable • Same cards for any band (Ku, C, Extended C, Ka) • Works seamlessly with iNFINITI line cards XLC-10 (One Modulator) XLC-M (Multi Demod)
iDirect’s DVB-S2/ACM Specifications •System Performance • Supports all modulation types: QPSK, 8PSK, 16APSK, 32APSK • Supports all LDPC Code rates • Full support for ACM • Maximum Symbol Rate: 45 MSym/s saturate a 54 MHz transponder • Data Rate: up to 140 Mbit/s using 16APSK • Leverages current industry-leading iDirect MF-TDMA upstream
But What Makes iDirect DVB-S2 Unique? •Integration of Satellite and Terrestrial Networks •Multiple Topologies for Multiple Services •Ease of Management •Efficient MF D-TDMA Return Channel
Seamless Integration with MPLS backbone •QoS Integrated with ACM •Enhanced Capabilities are Required • Advanced Routing Protocols: BGP, OSPF, VLAN Tags • VLAN to MPLS mapping • Encryption and VPN • IPv6 Support • Security • Open NMS Interface
What is BGP? •BGPv4 is the core routing protocol of the Internet. It connects enterprise networks to ISPs and ISPs to other ISPs. •BGP is an advanced routing protocol that makes routing decisions based on path, network policies and rule sets. •BGP neighbors (or peers) are established by manual configuration between routers.
Why BGP over RIP? - Stateful Routing •RIP constantly sends it’s entire routing table as it is stateless. We have always recommend not to use it over the RF segment for this reason. •BGP is a stateful protocol, so it does not transfer any user data after convergence. •BGP speakers run a minimal keepalive protocol on top of TCP. •iDirect extensions allow for no keepalive packets on the RF side. Zero steady state overhead!
Why BGP over RIP? - Policy •RIP’s only factor in routing decisions is hop count. •BGP will consider different attributes, in selecting the best path for a route. •BGP can be configured to allow/deny routes based on these attributes. •Network administrators can modify attributes. •Finally, a BGP speaker can configure all of the above for import or export to each individual peer.
Multiple Topologies for Multiple Service Offerings •Traditional Networks : • Fixed star-topology enterprise networks • Operators offered single service to single market •Large and Small Network Operators Now Offer Multiple Services for Different Markets • Hub allows services to be customized for each user •Topologies Offered at Every iDirect 5IF Hub : SCPC, mesh, star, and multi-star. iDirect supports Multiple Topologies on the Same Hub
