Big Data: What’s the Network Impact?

Network Instruments - Big Data: What's the network impact

According to Gartner® 42 percent of IT management has either already invested in big data technology or plan to do so in the next year. But given the overuse of the term by everyone from media pundits to IT vendors, will it really impact the network? The short answer is yes.

Within the next two to four years it will drive every aspect of IT, from infrastructure design to network and application management. In this article, we define big data, assess its impact, and provide advice on how network teams can best prepare.

The key factor behind big data is cheap storage to house the data-crunching results of applications that generate huge volumes of unstructured data. This data can include everything from high-definition video streaming to oil and gas exploration metrics to results from genome mapping and pharmaceutical research. For companies involved in these efforts, these activities require vast amounts of compute power and storage, real-time delivery of research, and well-defined access and security protocols. For network operations teams, this demands effective management of capacity, latency, access, and security.

Challenge Key Considerations Network Team Takeaways
Where do we store all this stuff?
Handling petabytes of information requires scalable infrastructure with the ability to quickly add or subtract capacity in a manner that’s transparent to users. The most common methods for achieving this are via public Infrastructure-as-a-Service cloud platforms or private cloud with automated resource provisioning. Tracking big data performance requires visibility into cloud storage, and benchmarking component performance and response time.

Also, confirm that your monitoring solution can track high-speed link performance without dropping packets.

How fast can I have it?
Real-time delivery of results is key to big data. When serving up custom content to users, instant results are needed. Regardless of web content or number crunching, late delivery directly impacts the bottom line. To identify bottlenecks means having a performance platform capable of providing integrated views of your overall big data services. Upon pinpointing choke points, infrastructure can either be optimized or upgraded.
Who needs the data? Are there database compatibility issues that prevent comparisons between data sets?
Big data often draws new parties into the data sharing loop. First determine who needs authorization to run queries or processes. The new consideration is whether data sets held on multiple backend storage platforms can be compared and correlated. To address this, the storage team will deploy some type of global file system. Utilize retrospective analysis to validate on-time resource access by authorized users and to track performance and potential breakdowns between database systems.
How do regulations impact data handling and storage?
First, privacy and security regulations impact how financial, medical, and government information can be housed and accessed. The co-mingling and comparison of sensitive data sets will create new headaches for IT managers who will need to track how this new intelligence is shared and utilized. And as data becomes largely created or housed externally, security policies will need to be drafted to take this into account. Stream-to-disk technologies like GigaStor complement existing security tools by acting as a network surveillance camera. Applying stream reconstruction and network forensics to relevant time periods allow you to investigate, verify, and document malicious or accidental security breaches.

Fongo bid a sandwich short of a picnic, scoffs Wind

Canadian mobile VoIP provider Fongo has announced that it plans to table a bid to take over cellular network operator Globalive Wireless (Wind Mobile), although the proposed offer – a token one dollar purchase price plus a 49% stake in Fongo’s business – has been dismissed as a publicity stunt by industry analysts quoted in the media, while a Wind spokesperson appeared to pour scorn on the idea. Simon Lockie, Wind’s chief regulatory officer, took to Twitter to comment: ‘I hereby publicly offer to buy Fongo for a dollar and half my sandwich. Hopefully the story gets picked up before I get too hungry to deliver.’

Fongo offers cheap VoIP calls and messaging via mobile users’ existing 3G/4G data plans and over Wi-Fi connections, including calls to mobiles, landlines and other Fongo phone numbers; its Fongo-to-Fongo free calling network covers over 85% of Canada including 30 of the largest metropolitan areas in all ten provinces. Users may also port an existing mobile or landline phone number to Fongo for a CAD25 (USD24.60) one-time fee. Fongo said its takeover plan involves migrating Wind subscribers to Fongo’s IP calling services ‘within a year’. It claims that over the last twelve months more than a quarter of a million users in Canada have signed up for its VoIP services, accessible via a mobile app. The Financial Post writes that Fongo has publicly disclosed CAD1.7 million in venture capital investment from Tech Capital Partners and angel investors and also received a repayable loan of up to CAD850,000 from FedDev Ontario in November 2012 for research and development of the next phase of its mobile service. However, the supposed takeover target Wind is estimated to be valued at roughly CAD750 million, with its 2100MHz wireless spectrum alone costing CAD442 million in 2008, while it has over 600,000 subscribers.

It was recently reported that Wind’s parent group Vimpelcom is putting the cellco up for sale while it waits for approval of a deal to take overall control of its shares; Wind’s Canadian founder Anthony Lacavera and original financial backer Naguib Sawiris are tipped to buy back the company

Rogers expanding LTE to 44 new markets this spring, including 2600MHz coverage

Rogers Communications has announced that it will expand its 4G LTE mobile network to 44 additional markets this spring, and it intends to reach a total of 95 markets by the end of the year. Rogers also stated that it will make 2600MHz LTE coverage available in all areas covered, augmenting its 2100MHz-based services, while 34 of the 44 new LTE markets will be capable of maximum theoretical network speeds of up to 150Mbps.

Among the 44 LTE markets launching this spring will be Saint John, New Brunswick; Medicine Hat, Alberta; Sault Ste. Marie, Ontario; Guelph, Ontario; Muskoka, Ontario; Collingwood, Ontario; and multiple cities in Quebec, while Rogers said that these rollouts will give over a million Canadians in Atlantic Canada, Alberta, Ontario and Quebec access to its 2600MHz 4G services.

Current Rogers ‘exclusive’ 2600MHz-enabled devices include the LG Optimus G 2600, the Rocket Stick modem, Rocket Hub and Rocket Mobile Hotspot, while it says it will announce more 2600MHz-enabled smartphones in the coming months.
