1. Consider a CORBA-based modeling of the interface table that uses two approaches—a single
method that returns all the interfaces similar to a SNMPGetBulk and separate methods for each
interface similar to SNMPGet (a one–one mapping from SMI to IDLs).
(a) Which of the approaches is more suitable?
(b) Explain why it is more suitable
2. In a Management system at a Service Provider, it is required to query a device for SysUptime,
tcpActiveOpens, tcpPassiveOpens, and tcpAttempts. A designer Anil wants to use SNMP for this
while Bina wants to use CORBA (1 method call for SysUptime, 1 for the remaining 3 parameters).
Which of their approaches uses less bandwidth? Why?
This NMS also has to retrieve the ipRouteTable, which has about 10,000 rows. Anil suggests
SNMPv2 GetBulk command, while Bina prefers CORBA (1 method to fetch the table). Whose
approach results in less bandwidth being used? Why?
