This illustration depicts a sample session tree with five nodes and their associated commit point strengths (in parentheses). The illustration also describes determination of the commit point site. The five nodes and their associated commit point strengths are SALES.ACME.COM (45), WAREHOUSE.ACME.COM (140), HQ.ACME.COM (165), FINANCE.ACME.COM (45), and HR.ACME.COM (45). HQ.ACME.COM is determined as the commit point site because it has the highest commit point strength.
