Integrated Services policies

Integrated Services (RSVP) policies are used to set limits on certain parameters requested by RSVP applications. These applications interact with the RSVP Agent to establish resource reservations along a network path, using the RSVP API (RAPI). The reservation requests are in the form of an entity known as a Traffic Specification, or Tspec, which consists of the following values:
  • Token bucket mean rate (r)
  • Token bucket depth (b)
  • Peak rate (p)
  • Minimum policed unit (m)
  • Maximum packet size (M)

RSVP policies can be used to limit the values requested for (r) and (b), as well as limiting the total number of RSVP reserved flows. The RSVP service attributes are enforced by the RSVP agent which gets RSVP policies from the Policy Agent. For additional information on the enforcement, see z/OS Communications Server: IP Configuration Reference or RFC 1363.
