This two-day course provides students with advanced class-of-service (CoS) knowledge and configuration examples. The course begins with an overview of CoS before going into classification, policing, scheduling, and rewriting. The course then covers class-based forwarding and finishes with a case study. This course is based on the Junos operating system Release 12.3R3.4.
Through demonstrations and hands-on labs, students will gain experience in configuring and verifying Junos CoS features.

Junos Class of Service is an advanced level course.
