PROJECT EXPERIENCE:
Project #01 Cisco Service Control Engine - Subscriber Manager Dev test
Duration:(Sep 2010 to till date)
The Cisco service control solution is delivered through a combination of
hardware and specific software solutions that address various service
control challenges. The Cisco Service Control Engine is a Deep Packet
Inspection (DPI) solution that deals with L2 to L7 layers and protocols. It
is a network element specifically designed for carrier-grade deployments
requiring high-capacity stateful application and session-based
classification and control of application-level IP traffic per subscriber.
The SCE platform is powered by the SCOS SW that enables the loading and
execution of service control applications .It allows to identify the
content transported on any protocol (L4 to L7 protocols) and prioritize the
sessions in real time. It also provides quota and bandwidth management.
The module given for testing is called Subscriber manager which basically
stores all subscriber information including quota information. These
records will be processed by the service provider in order to generate
billing for the customer and also for generating graphs and trends for
Business intelligence. My work involves in manual testing, Bench mark
Testing, Regression testing of 3.6.5 release and also for testing the
various new features in 3.7.0 release.
My Job responsibilities are shown below:
. Apply DPI in L4 to L7 and test the behaviour, working and correctness
of the product from end-end with DPI and major Networking protocols
involved. Primary task also
. Testing SM which manages the subscriber details (name, net id and
policy) and Provide the information to SCE device simultaneously or
based on SCE request.
. Regression testing in various platforms and in cluster setups.
. Performance testing across various platforms for 3.6.5 and 3.7.0 SM
release.
. Developing test plans for testing the new features of 3.7.0 release.
. Automation of the cases in java and manual testing .
. Manual and automation testing of the SCE box with SM module by pumping
real traffic by using Ixia, sesame and various tools like gulliver.
. Setup the topology and execute the test cases manually.
. Finding bugs and tracking them till they are resolved to fixed status
and also scripting case to verify them.
. System -BM Testing and System - Regression Testing.
. Communicating with Dev and Prod Team
. Guided escalation team for Severity one customer issues make it
solved.
. Building up the test setups and recreate the Customer found defects
