 The challange of NG-SDH
X Growth in broadband and multimedia data services
X Carriers and Service Providers aim to
• maintain high margin revenues from legacy services
• generate additional revenues from new services in a cost-effective
way (Ethernet, SAN, 3GMobile)
X Many carriers are basing their network evolution strategy on
NG-SDH Multi Service Provisioning Platforms (MSPP)
X MSPP trend to account around 40% of global metro market in
2005-2007 (IDC, RHK, Dell’Oro, Alcatel 2003)
X MSPPs economical benefits for Carriers:
• Savings on Capex and Opex, as existing legacy transport
infrastucture is leveraged and revenues on legacy services
protected
• New revenue generation by enabling new broadband services
• Smooth evolution path to network convergence
