key feature ddos protection
Key Feature: DDOS Protection
  • Automatically enforced blacklists for remote IPs
  • Intelligently applied to IP addresses or Subscriber, based on feature server response
  • Controllable timers allowing various block periods
  • Applies to Registrations, Invites, Subscribes, Option polls and protocol errors

key feature call admission zone
Key Feature: Call Admission Zone
  • Customer and vendor call admission control enforced across all network elements on Trunk ID basis
    • Can manage CPS, RPS and session count across pool of VSXi systems
    • Configured in single GUI screen

Example: CPS capped at 100 cps for TID 10,000 – managed across Co-Lo 1, 2, & 3

Trunk ID 10,000

key feature network license
Key Feature: Network License
  • VSXi “Network License Zone” shares a pool of session capacity across a network of VSXi hardware
  • Better support for geographic redundancy and distributed hardware
  • Shown below: 6 nodes in 3 high availability pairs supporting 3 interconnect points - pool of sessions shared across all nodes

  • Enables more efficient use of session capacity across nodes
  • Shown below: network snapshot of traffic across 6 nodes that are licensed for a total of 5000 sessions

  • NLZ loading is 4500 sessions at snapshot
  • Each co-location better able to handle localized traffic bursts using shared pool of buffer capacity
modular system design

gsma ipx operator
GSMA IPX Operator
  • Enables intelligent SIP-I session switching and media optimization with Pathfinder ENUM
mst2 transcoder
MST2 Transcoder
  • 1U server with Sansay DSP card
  • Licensed on a network wide basis
  • Transcoding session count is tracked along with but separate from NLZ
  • Provides added value for applications:
    • Long tail echo cancellation up to 728 msec
    • DTMF translations
    • T.38 translations
mst2 transcoder cont
MST2 Transcoder (cont)
  • Highly scalable yet low cost per port
    • Add up to 4000 sessions per 1U rack space
    • N:1 redundant and NLZ make for lower TCO
  • Integrated into TID config for easy routing
    • Makes routing independent of codec concerns
  • Redundant RTP (RRTP) for best OTT quality
  • Video transcoding supported at limited size
tsx transcoder
TSX Transcoder
  • Integrated INX/MST2 for easier deployment
  • Has a new system type with limited functions
    • This is similar to Peering Edition; ie, lower cost
  • Still supports NLZ for redundancy and building distributed networks
  • HA Redundant for highly reliable POPs
  • All DSP (audio) aspects are same as MST2
introducing rome
Introducing ROME
  • HRS – High-speed Route Server
  • Centralized management of Routes
    • Simplifies route management
    • Improves system operating performance
    • Expands number of routes operators can manage
  • Enables more sophisticated routing
    • Enables simple & flexible jurisdictional determination
    • Supports up to 50 alternative routes
rome operations
ROME Operations
  • Stateless server, routes held in RAM for extremely fast processing
  • Queried via SIP protocol
  • Route uploads do not affect system CPS
  • Server updated / managed via GUI and SOAP
  • VSXi can recurse with TID mode
    • Provides compatibility with variety of policy servers (Nuestar Pathfinder, ATT, etc)
functioning in the network
Functioning in the Network
  • ROME can be added to existing VSXi network
  • ROME typically deployed at Super POP or core network hub
  • ROME deployed in LB mode with Active-Active systems
  • Can also be deployed in geo-redundant config

ROME Accepts queries and provides routes across INX nodes
