DC-RSVP

More information

ReSerVation Protocol with Traffic Engineering (RSVP-TE) is one of the label distribution protocols supported by DC-MPLS. DC-RSVP provides a complete, scalable, and fault-tolerant source code implementation of RSVP-TE.

DC-RSVP is designed for OEMs building a wide range of devices including MSPPs, routers, Carrier Ethernet, enterprise switches, mobile backhaul, packet – optical transport, ROADMs, or WDM devices. It includes a wide range of protocol extensions for both packet and optical networks, including advanced features such as diffserv, GMPLS, MPLS-TP, G.709 OTN, OIF-UNI and OIF-E-NNI.

DC-RSVP is also available as a pre-integrated MPLS control plane with Metaswitch's IP Routing software providing a fully Integrated Control Plane for packet and optical devices.

Management and Integration

Fully MIB manageable
- LSR MIB
- MPLS TE MIB
- Product management MIBs for consistent management interface
Easily integrated with SNMP, CORBA, CMIP, CLI, Web or other management paradigms, including Metaswitch's Configuration Safe Store
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 Metaswitch's Configuration Safe Store

Carrier Class Design

Scalability
- Optimized mainline for very fast LSP establishment and refresh processing
- 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
- High availability through replication of config and state data for backup control plane
- Hot software upgrade
- Control plane restart with LSP survival
- Protection switching and fast re-route (includes e2e recovery)
- Availability and fault tolerance in management of configuration information possible with Configuration Safe Store
- See High Availability for more details
Interoperability
- Major vendors: interoperates with all major implementations
- 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.
