DC-LDP
An introduction to LDP and its uses
Label Distribution Protocol (LDP) is one
of the label distribution protocols supported by DC-MPLS.
DC-LDP provides a complete, scalable, and fault-tolerant
source code implementation of LDP.
DC-LDP is designed for OEMs building MSPPs, Carrier Ethernet, enterprise switches,
routers, mobile backhaul, or packet – optical transport devices, and provides
a wide range of protocol extensions for VPN,
VPWS and VPLS,
including RFC2547 BGP/MPLS VPNs
and PWE3 (Martini).
LDP Protocol Function
The DC-LDP software product includes the following LDP protocol
function.
- RFC 3036
- IPv4 and IPv6 support
- Unnumbered interface
- Support for all combinations of label management modes
- Downstream Unsolicited and Downstream on
Demand Label Advertisement
- Liberal and Conservative Label Retention
- Ordered and Independent Label Distribution
- Targeted adjacencies
- Loop Detection using both Hop Count and Path Vector
- Layer 2 VPNs
- PWE3 architecture (RFC 3985)
- VPWS (Martini) (RFC 4447)
- VPLS (RFC 4762)
- Layer 3 VPNs
- LSP Ping
- Extensible for OEM specific requirements
- Support for private objects and TLVs
- Proprietary data transferred across external interfaces for OEM processing
- Support for proprietary MIB extensions
- Support for OEM specific authentication
Management and Integration
- Fully MIB manageable
- LSR MIB
- LDP MIB
- Product management MIBs for consistent management interface
- Easily integrated with SNMP, CORBA, CMIP, CLI, Web or other management paradigms
- Pre-integrated CLI, XML/Web and SNMP management interfaces
available through MINDLink(Metaswitch), an embeddedMIND™
product from our partner GoAhead Software.
- High availability and fault tolerance in management of configuration information when
used with Configuration Safe Store
Carrier Class Design
- Scalability
- Optimized mainline for very fast LSP establishment
- Binary trees ensure scaling of O(ln(N)) with number of LSPs supported
- No hard-coded limits to number of interfaces or LSPs supported
- Designed to handle thousands of interfaces and millions of LSPs
- Distribution of components onto multiple cards
- Carrier class availability
- Interoperability
- Major vendors: interoperates with all major implementations, including Cisco
and Juniper
- UNH-IOL: successful testing of all aspects of DC-MPLS at UNH Interoperability Lab.
See http://www.ioh.unh.edu/consortiums/mplsServices/
for details.
- We assist customers in their own testing, either in their labs or at
customer field trials
- Guarantee: interoperability problems are treated as problems and fixed
within the same schedules.
