Differentiated Services/Quality of Service (DiffServ/QoS)
 
 

EION’s Differentiated Services (DiffServ) for IP Quality of Service (QoS) is a set of transparent and portable software components enabling policy-based QoS control and multiple levels of QoS.



DiffServ/QoS Highlights and Literature

EION Open IP Environment DiffServ for IP QoS demonstrates the following key features:

  • Configurable to run on either a DiffServ Edge device or a Core network device
  • Enhanced packet classification and filtering capabilities: BA (Behaviour Aggregate) and MF (Microflow) Classification
  • Flow Management2 module that permits accurate classification of fragmented packets
  • Configuration of filters and traffic profiles via COPS-client interface. It supports traffic Profiles’ PIR (Peak Information Rate) and CIR (Committed Information Rate)
  • Houses high performance meters at three levels: Filter-level Granularity, Interface-level granularity, and queue-level granularity. Supported Meter algorithms include: Sliding Window meter and Exponential Weighted Moving Average meter (EWMA)
  • Supports different DiffServ Policers that operate on specified trafficprofiles which are: single rate Three Colour Marker (srTCM, two rate Three Colour Marker (trTCM), Time Sliding Window Three Colour Marker (TSWTCM) and Two Color Token Bucket (tcTB).
  • Allows Rate Limiting per Egress Interface
  • Includes a number of hot-swappable packet schedulers. The schedulers supported are: Round Robin (RR), Weighted Round Robin (WRR), Weighted Interleaved Round Robin (WIRR), Bounded Strict Priority (BSP) and Weighted Fair Queuing (WFQ)
  • Features configurable Traffic Shapers: Token Bucket and Leaky Bucket shaper
  • Showcases a variety buffer management algorithms (e.g. Drop Tail, Random Early Detect (RED), Multi-Level RED (MRED), RED with In/Out (RIO-Coupled), Weighted RED (WRED), RIO-Decoupled and Explicit Congestion Notification (ECN)
  • Provides support for defined PHBs standards: Class Selector (CS) PHB, Assured Forwarding (AF) PHB, Expedited Forwarding (EF) PHB and Default (Best Effort).
