Chinese telecom giant Huawei is leading the overall SDP market and is most likely to displace Ericsson and Oracle from their leadership positions in 2011, says market research firm Infonetics Research.

The service delivery platform (SDP) market is growing rapidly around the world, and the analyst firm predicts the worldwide SDP software and services market may reach $5.2 billion in 2015.

As of today, according to the research firm, Ericsson (News - Alert) holds onto the No. 1 spot as far as SDP services revenue is concerned, and Oracle is racing ahead in SDP software segment.

According to the researcher, momentum around the cloud services opportunity will generate interest in using an SDP to support the on-demand, and real-time service requirements associated with a cloud offering SDP markets are growing in developing regions in Asia Pacific, Central and Latin America (CALA), and the Middle East, where operators' SDP deployments have begun to pick up steam.

 "Interest in API exposure continues to fuel momentum in the SDP market, as do operators' app store strategies, although operators are increasingly regarding these initiatives as ways to differentiate their offerings in competitive markets as opposed to significant revenue opportunities,” said Shira Levine, Infonetics Research's (News - Alert) directing analyst for next gen OSS and policy.

The report titled Service Delivery Platform Software and Services tracks fixed-line and wireless SDP software and services that operators use to create and deliver services to their subscribers.

“While consumer services continue to be a primary driver behind SDP market growth, we see an emerging opportunity in the B2B space, including using SDPs to support machine-to-machine (M2M) applications and cloud-based application delivery to the enterprise and SMB market," Shira Levine adds.

The report tracks revenue for consulting, integration and hosted SDP services, and the 5 main SDP software components: network and subscriber abstraction, SDP framework, service creation environment, service orchestration, and Web services environment.
