Service providers, enterprises, and operators have been suffering a lot to maintain, operate, expand, integrate, and migrate their out-of-dated infrastructure with legacy products such as Cisco CPT (Carrier Packet Transport) devices. Adding to the complexity is that most of the products have exceeded its intended lifespan. They’re receiving manufacturing notices such as the end of manufacturing, end of service, and end of life. This aging infrastructure, combined with the need to act, is creating both business and technical challenges for their engineering operations teams to keep such infrastructure operating effectively.
