Beware Systems Integrator Lock-In, Open Source Dependency
Telcos are worried that systems integrators and open source will replace giant equipment vendors as a form of lock-in.
AMSTERDAM -- Broadband World Forum 2019 -- Kings can be tyrants, but at least they give you an easy target to punch when something goes wrong and revolution follows. Telcos in a perpetual huff about the ruling trio of Ericsson, Huawei and Nokia could be in for a more slippery autocracy with the emergence of systems integrators, a cabal of tiny vendors and some unwieldy open source platforms.
Operators are worried, too. "Yes," said BT's Simon Fisher when asked during a panel session here if there is a danger of going from one form of lock-in to another. "You are squeezing complexity and cost into the software side of the business."
Fear has grown as operators lurch toward their vision of a more open network built and managed by a multitude of hardware and software companies -- rather than one big player. This dramatic shift is designed partly to ensure telcos investing in new technologies are less reliant on a small number of industry giants. The trouble is that piecing together components provided by so many different suppliers is like trying to build a Tesla with random parts, using a team of ageing mechanics.
Challenged on the skills front, many operators are dumping the hard work on systems integrators. India's Tech Mahindra, a familiar face in this market, has a unifying role in the project by Japan's Rakuten to build a "greenfield" mobile network based on the latest cloud and software-based technologies. More unfamiliar names are also popping up. Reply, an Italian company, has the honor of being the systems integrator for Deutsche Telekom's Access 4.0 initiative, which aims to replace the proprietary boxes used in central offices with commodity gear and open source code.
The danger BT's Fisher evidently sees is that one overlord replaces another, as the mighty systems integrator usurps the vendor. Instead of Nokia, the operator could find itself bound to a Tech Mahindra or Reply. Worse, this systems integrator, by definition, would be managing a collection of tools that did not come from its own workshop. At least in today's networks, Ericsson or Huawei are directly responsible for any problems.
Equally bad might be the emergence of colossal open source platforms promising magic solutions. While Fisher and his peers were deliberating the systems integrator lock-in, Mansoor Hanif, the chief technology officer of UK regulatory authority Ofcom (and a former telco executive), was issuing a similar warning about "over dependency on any single automation platform" in a clear reference to ONAP, the open source management platform backed by the increasingly powerful Linux Foundation.
Speaking on a panel during the SDN NFV World Congress, just down the road in The Hague, Hanif urged caution for security reasons. "If you can actually get control of the whole network and reconfigure it, obviously that's the danger of a programmable network that's non-secure," he said, according to Heavy Reading Senior Analyst James Crawshaw, who posted comments about the event on his LinkedIn page.
"I guess the fear is that because ONAP is open source it will be easier for bad actors to explore (than a commercial solution) and, if widely adopted, worthwhile trying to hack," noted Crawshaw.

For operators, the alternative is to get their hands dirty and do more of the systems integration and technology development themselves. But many, including some of the biggest players, lack the requisite skills. "I think we can [succeed] but when you have to take a big legacy network with you and legacy behavior, that is a complex challenge," said BT's Fisher.
Indeed, France's Orange last year estimated that around 50,000 employees, equaling about one third of its entire global workforce, would need "reskilling" to prevent the company from dropping far behind cloud providers such as Amazon Web Services and Microsoft Azure. Spain's Telefónica recently announced plans to retrain about 6,000 employees in areas such as security, robotization, analytics, web development, IT and -- believe it or not -- "agile methodology capabilities."
None of it will come cheap. Telefónica has estimated that staff training, and a related early retirement initiative, will cost about €1.6 billion ($1.8 billion). And even if it can shrink the bill for capital expenditure, the shift to open source technologies and multivendor networks could bring all manner of other expenses, too. "We should not forget about looking at operational expenditure and energy consumption and update management and TCO [total cost of ownership] considerations," said Gerhard Kadel, a senior architect at Germany's Deutsche Telekom, speaking here in Amsterdam. "In that environment, it really is a challenge."
