As
enterprises grow and expand their operation, the need for a better and improved
connectivity services with assurance quality of services is becoming the order
of the day. The enterprises are
becoming more demanding. Also, the kind of SLAs, which they are asking from
service provider, has undergone a tremendous change over the years. Today the
connectivity options to the enterprise customers are multifold, offering their
unique benefits. Enterprises have different strategies for their core network
and their distribution network. Core network is the backbone of any
organization. There is a serious shift from TDM and leased line systems to other
technologies like MPLS. Cost is the biggest factor.
Most enterprises are not comfortable moving out of a private to a public
network. The responsibility of providing quality service in VPN rests primarily
with service providers.

With convergence and shift from TDM to IP, the concept of single network
providing all services is gaining ground and so the concept of connectivity
services is catching up. Earlier, service providers used to offer services as
per the license agreements, eg basic service providers used to offer basic
telephony and ISDN services whereas NLD operators used to offer leased line
services. But large operators now opt for all types of licenses (basic,
cellular, ILD, DLD, ISP, VSAT, international connectivity services such as ATM,
frame relay, IP-VPN, and MPLS-based IP-VPN). Initially, all the operators were
busy with infrastructure deployment but with majority of the deployments
complete in large cities, the concept of integrated service became the order of
the day. However, enterprises are also going for the services from specialised
service providers like VSAT operators.
With integrated service provider such as BSNL, Bharti, Tata, and Reliance
coming into the picture, service providers are offering the complete bouquet of
services for enterprises. This is beneficial for both service providers as well
enterprise users. Connectivity services not only look at providing
communications services but also includes: Design, integration, security, and
network management-all as a complete package. Even if integrated service
providers provide connectivity services, all the services apart from
communications services can be taken care of.
So, in some cases, the integrators might compete with and in some cases
they may even collaborate with the telecom service providers. So, the
integrators in some cases manage on behalf of the telcos and in other they
manage the telcos-when they are the system integrators for the corporations.
Here, integrators have had an advantage over telcos as they understand SLAs
better.
Service providers have restructured their organization structure as they
feel that it is better to go with complete solution rather then focusing on
individual services marketed by different individuals in the same organization.
All the integrated service providers provide all kinds of services such as
wireless or wire line, TDM or IP, and voice or data. For example Tata Indicom
Enterprise Business Unit (TIEBU) is the enterprise division of Tata Teleservices
and provides services from Tata Teleservices, VSNL, and others. Reliance
Infocomm also has an enterprise division and so does Bharti's enterprise
division called Airtel Enterprise Services. Even, the incumbent operator is not
planning to be left behind and has formed an enterprise division.
Presently, incumbent operators, BSNL and MTNL have a large market share
and all private operators are targeting the creamy customers of incumbent
operators. The coming of private operators has increased the quality of service
from BSNL and MTNL. And the incumbents have become more responsive. In terms of
reach, private operators still have a long way to go in comparison to the
incumbent operators.
