  • Page 11: Configuring Service Placement

    C H A P T E R Configuring Service Placement In Cisco NPS, the Service Resolution Engine (SRE) performs service placement recommendations. In other words, this is the selection of a data center from a number of data centers that support a requested service.
  • Page 12: Service Resolution Engine Ranking Requirements

    A user can select a combination of different performance attributes and assign different ranking priorities to them. Service Resolution Engine Configuration Perform this configuration on a provider edge router (PE) to enable the service resolution engine (SRE). Cisco recommends running the SRE on a DCE-facing PE in your network. SUMMARY STEPS 1.

  • Page 25: Configuring The Routing Protocols Used For Network Proximity

    How to Configure Routing Protocols, page 21 Information About Network Routing Proximity The proximity engine (PXE) in Cisco NPS uses network routing proximity to select a data center based on its topological distance and path distance from the client. The PXE gathers topology and path information from both IGP (IS-IS, OSPF) and EGP (BGP).
  • Page 26: Pxe Data Elements

    • PTL—Proximity Target List. This is a collection (ranked or unranked) of PTAs. The conventional value for a PSA or PTA is an IP address/mask combination. Cisco NPS, PXE is expected to process IP addresses; therefore, outside of PXE, any other form of identifier must be converted to an IP address/mask.
  • Page 27: How To Configure Routing Protocols

    BGP is the de-facto EGP standard and the basic algorithm for BGP proximity relies on the AS_PATH attribute. The computation is very similar to the IGP version, except that path costs are used rather than link costs. Cisco NPS does not support inter-AS topologies for proximity calculations.

    Configuring BGP for Proximity Calculations Use this task to configure the Border Gateway Protocol (BGP) routing process for proximity calculations performed by the proximity engine. Cisco Network Positioning System Configuration Guide for the Cisco ASR 1000 Router, Release 1.0 OL-25794-01...
