Path Computation Element (PCE)
Defined by the IETF, PCEs provide operators of MPLS/GMPLS networks an evolutionary path to Software Defined Networking (SDN) enabling seamless inter-domain routing, flexible/customizable path computation, improved price/performance, and simplified operations.
Metaswitch DC-PCE
Metaswitch provides a complete PCE solution for OEMs. For more information see
our DC-PCE product page.
- PCE Client Solution
- DC-PCE provides a PCE Protocol stack for PCE clients
- It is pre-integrated with Metaswitch’s DC-RSVP
product to allow PCE queries for MPLS-TE tunnels
- Simple for users of Metaswitch Integrated Control Plane to take advantage of PCE Client function
- PCE Server Solution
- DC-PCE provides a PCE Protocol stack for PCE Server
- Autodiscovery via OSPF and IS-IS
- DC-PCE is pre-integrated with Metaswitch’s DC-OSPF
and DC-ISIS products
- This allows PCE Clients to automatically discover the location of PCE Servers
in the network
- Facilitates providing backup PCEs and PCE upgrade
PCE Applications
DC-PCE has been designed from the outset to support every PCE application in the most
demanding scenarios
- Different server and client architectures
- PCE server function can be added to an existing MPLS switch, located
on a standalone server or in a server cloud
- PCE client function can be located on an MPLS switch or in a
network management application
- PCE server and client function embedded in a network element
- Stand alone PCE server in the cloud
- PCE client and/or PCE server embedded in a third party OSS
- Software Defined Networking (SDN)
- End-to-end inter-domain routing
- Backwards recursive computations (BRPC)
- Path key encryption
- Many network types
- WDM / DWDM networks
- G.709 OTN
- SONET/SDH
- Ethernet (1G/10G/40G/100G)
- MPLS-TP
- Multi-layer
