Advanced Services in Converged Networks - Are
they Really Manageable?
The explosive growth of Internet and telecommunication
services, fast proliferation of advanced network devices and integration
of different technologies and applications in a rather complex network
have created a unique challenge for the network management community.
New ways of strategic thinking must be incorporated in future management
products and services to ensure a smooth transition towards the
future networked society. Enormous change in the telecommunications
industry is being driven by the convergence of the traditional Public
Switched Telephone Network (PSTN) with the Internet. With this change,
we are also seeing the convergence of data services with voice and
perhaps ultimately with video and other rich services. Not surprisingly,
increased complexity is attendant to these changes, and this complexity
implies new and daunting challenges for the management and operations
community. Will the network management and Operational Support Systems
(OSS) be able to keep pace as the next generation services are rolled
out? What are the long-term prospects for comprehensive management
of these functionally expansive telecommunication systems? What
might the consequences be if management and operational systems
were to remain fragmented and isolated? How great is the risk if
the converged networks end up in a brittle network, due to limitations
of their management systems? What needs be done to keep the Converged
Network manageable? Are the management issues getting the needed
attention? These are some key questions that will be addressed.
- Many networks today are constructed from
some combination of DWDM, SONET, ATM, and IP. Peering across the
layers is already difficult. Will integration of voice and advanced
services exacerbate this problem?
- Traditional PSTN voice and Voice over
IP (VoIP) will not only coexist Š they will likely need to interoperate
extensively! This will potentially introduce not only complexity,
but also significant scaling issues.
- SNMP-based management in the Internet
world has succeeded brilliantly at the Element Management Level
(EML), and on the Fault and Performance aspects of FCAPS. How
readily can existing Internet management methodologies be extended,
or new methodologies be developed, to support a broader range
of management functions? How quickly will tools emerge to manage
comprehensively at the Network Management Level (NML) or Service
Management Level (SML)?
- There has been much interest in recent
years in policy-based management of Internet functions, essentially
as a means of moving the provisioning of DiffServ, MPLS and IPSEC
services to the NML or possibly the SML. What are the prospects
for these efforts in terms of standardization, implementation
- What new functions might be needed at
the Business Management Level (BML)?
