3. 3H00000 5/24/2015 Advanced Bandwidth Management Four Different Service Profiles Dynamic Streaming No Jitter And Rate Guarantees Bandwidth Allocation is Backlog Based Constant Bit Rate (CBR) Low Jitter Guaranteed Rate Adaptive CBR Medium Jitter Guaranteed Minimum Rate Predefined steps between Min and Max CIR Enforced Maximum Rate Committed Information Rate (CIR) with Best Effort Medium Jitter Guaranteed Minimum Rate Best Effort between Min and Max CIR Enforced Maximum Rate  Service profiles are set per remote – not per Inroute or network  Outbound and Inbound service profiles can be configured independently  One Inroute Group can support any or all of the various service profiles

4. 4H00000 5/24/2015 Adaptive CBR Bandwidth Management  Each session configured with the following parameters – Minimum CIR (Kbps) – Maximum Rate (Kbps) – Step Increment (Kbps) – Usage threshold (% of utilization) – Idle Period (can be eternal) UPSTREAMDOWNSTREAM MAX Rate MIN CIR No allocation Low jitter minimum bandwidth per terminal Maximum bandwidth per terminal No bandwidth assigned if no traffic STEP 1 STEP 2 Usage Threshold  Traffic Between The Minimum And Maximum Rate; – Fixed “step” increments  Flexibility Of Exceeding The Min Rate When Bandwidth Is Available In The Network  Outroute CIR Allocates Resources Only When Outroute Data Is Backlogged.  Inroute CIR Minimum Is Allocated Independent Of Backlog.  Inroute CIR Session Is Released When Inactive For A Predefined Interval.

5. 5H00000 5/24/2015 CBR V CIR  Constant Bit Rate) A uniform transmission rate. For example, real-time voice and video traffic requires a CBR to lessen jitter.
