Overview

• Simple ID to specify new code points for DS-TE
  support
• DS-TE identified as a requirement in inter-area
  TE and inter-AS TE requirements (RFC4105 and
  RFC4216)

3
Specifics

• Path computation for a DS-TE LSP must take into
  account the class-type (CT) bandwidth constraints
• A PCE needs to know the CT of a path computation
  request it receives

4
Purpose of the draft

• Defines an optional CLASSTYPE object for PCEP
  (matching that of RFC4124)
• The CLASSTYPE object is carried in the PCReq
  message and specifies the CT to be used for the
  path computation

5
Changes from version 0 to 1

• Proposed class type and error type are 18 and 15
  respectively
• Described the significance of CT

6
Next Step

• Adopt as a WG document ?
