Choosing a Transport Method


This chapter describes the methods for transporting packets between replicas. The method you choose depends on connectivity between replicas. If your replicas do not have IP connectivity, you must use a file-based method. If your replicas have connectivity, you can use the store-and-forward facility of Rational ClearCase MultiSite.

Table 13 lists the recommended methods for various situations.
