cly traded companies, buying software and hardware while older equipment is on their books lowers their net income. This may result in lower stock prices and shareholder discontent, dampening telecom companies' incentives for costly upgrades. One strategy that telephone companies use to implement Central Office Re-architected as a Data Center (CORD) is to add CORD data center elements within their traditional central office. In this way, the functions in traditional central offices can be gradually transitioned to CORD equipment and virtualized servers. www.TechnicalPDF.com Telephone companies are additionally merging mobile central office functions (the core in mobile networks) and their landline central office functions in CORD data centers. During the transitions clashes between the two types of staff may occur. However, the end result is lower costs to operate networks. The type of staff required to manage and program SDNs, CORD, and NFV are software engineers able to design, develop, test, and upload software compatible with the cloud environments where CORD offices are located. They additionally are required to understand ways to interface and integrate older network technologies with SDN and NFV via application programming interfaces (APIs). Staff that monitored network conditions from traditional central offices needed to monitor large telephone networks. In CORD, central offices cloud development (DevOps) skills are required to manage new central offices that are essentially large data centers. Session Routing-On Virtual Routers Burlington, Massachusetts start-up 128 Technology was founded in 2014 by staff at former networking company Acme Packet. According to founder Andy Ory, networks have gotten overly complex and costly, and are not suitable for today's traffic patterns. Current networks were designed to connect computers or remote access devices for brief information look-ups, not present-day network transactions, which are predominately session based. www.TechnicalPDF.com During sessions, people ty
