SailFin Tips : Advanced Configuration

  Lots of fixes have gone into SailFin 2.0, some of these fixes are related to functionality whereas others are to improve performance. The changes sometimes required creation of new user configurable properties in order to extract the optimal-performance/desired-behavior depending on the users deployment. This article tries to explain some of the properties/attributes that were introduced in SailFin 2.0 to address specific issues. Note : Not all these properties have been tested and certified.  Hence use them at your own risk. Please refer to the product documentation if you are using a supported version. Configuration related to DNS failover functionality : DNS failover is implemented in SailFin as per RFC 3263, it ensures that if the SIP message cannot be sent to the first host obtained from a DNS lookup then the next in the list has to be used to send the message. In case of UDP, to detect a message delivery failure at the network layer, we rely on the fact that an ICMP error response was received for the host that is not reachable. If for some reason (firewall or other) the ICMP error responses do no arrive , then we have to fall-back to the mechanism based on Timer B/F (defaults to 32) expiry to perform the retry. For sake of brevity lets call the former as fail-fast and the later as fail-safe. To implement the fail-fast solution, SailFin maintains a list of hosts for which a ICMP eror was received, and before se...
