Multi-Link Frame Relay Features
Supports provide Multi-link and Fragmentation services.
- Fragmentation services allow real-time and non-real time
data to co-exist on Frame Relay links.
- Multi-link services allow aggregating the
bandwidth of several links into one virtual link.
- Fragmentation may be enabled End-to-End,
UNI/NNI, or both
- Multi-link may be enabled End-to-End,
UNI/NNI, or both
- Fragment size set by configurable constants.
- Both services may be used in ISDN or
non-ISDN environments
Services are individually enabled to allow use in a
mixed interface environment
- Permanent Virtual Circuits (PVCs) &
Switched Virtual Circuits (SVCs) per FRF4
- DTE (User) Side + DCE (Network) Side (PVC only)
- Dynamic run-time configuration with Forum Local
Management Interface (LMI)
- Network Management Interfaces conform with
ITU-T Primitive Interfaces
- Q.933 Annex A and T1.617 Annex D PVC
- Modular structure easy to customize using
defined constants
- Higher-layer independence allows transparent
transport of other protocols, including:
- TCP/IP ,SNA, X.25/X.75 & ISDN
- Supports testing both sides of the network
- Layer 2 DL-CORE Module
- DTE & DCE Side implementation of Data Link -
CORE and LMI functions
- Functions supported include:
- Congestion Control and Explicit Congestion
Notification (ECN)
- Data Link Connection ID (DLCI), up to
922 users
- Multicast-configurable to network
needs
- Discard Eligibility bit
- Heartbeat Process to verify physical
link integrity
- 1024 PVC DLCIs for support of up to 255 active
connections
