California-based provider of network analytics solutions Saisei has helped Malaysia's Sunway Group to ensure fair and equal network service access for users, as well as improve security and performance, which included cutting costs by US$80,000.
"One of the big challenges we faced was that the first and largest group of users accessing our network consumed most of the bandwidth, compromising performance for other users and high-priority applications," said Daniel Soh, assistant general manager, Sunway Digital Wave (SDW), which is the managed services provider to property construction conglomerate - the Sunway Group.
"We started to get complaints about network performance from customers frustrated by slow applications and Internet access," said Soh, who added that SDW managed services and Internet access to a large and varied community of APAC users.
The Sunway Group operates in 50 locations worldwide and SDW must also bring new applications and next-gen devices onto the network as well as ensure fair and equal access to network services and high quality of experience (QoE) to all subscribers, he said.
Soh said that SDW has also been building out the Sunway Group's Software Defined Network (SDN) to support business expansion to new regions and new residential and commercial customers outside the Sunway groups as well.
He said SDW had been using Exinda's Network Orchestrator, and had evaluated other WAN optimisation and DPI solutions but none provided fair usage and the deeper, real-time network analytics and control they needed.
"We implemented Saisei's FlowCommand software because it was the only solution we found that could provide fair usage to all users," said Soh. "Customers get what they pay for and we can deliver the bandwidth needed for a high-quality, reliable user experience. Customers are much happier with the network performance, we get fair fewer complaints these days."
He said SDW has deployed FlowCommand at "the heart of their SDN network, and all Internet traffic goes through it."
Saisei's solution has a patented flow-control technology, which guaranteed equal access to each user or host regardless of how many users were on the network or what applications they were running, said Soh.
"Fair usage was the biggest requirement for us, but FlowCommand has provided a number of other great benefits in terms of much more advanced and instantaneous visibility, analytics and control," he said.
"The control of our bandwidth is markedly better across the board," Soh said. "We've improved bandwidth utilisation by more than 30 percent, which has translated into a more than US$80,000 bandwidth cost savings and delayed capex on upgrades for more than 6 months."
He said the solution identified, monitored and controlled every single flow on a critical broadband link - up to millions of concurrent data, voice and video sessions - in real time without any impact on network performance.
Aggressive applications -- including P2P applications, high volumes of YouTube traffic or file transfers, which grab huge percentages of link bandwidth and crash other users, get the same percentage of a link's bandwidth as every other user on the network with the usage of FlowCommand's metadata analytics.
"A good example of this is when FlowCommand helped us to see that traffic from student hostels and dormitories at Sunway University typically peaked between 4 p.m. and 1 a.m., so we'd need more bandwidth then and could allocate it to the hostel," said Soh.
"With time-based policy control, we can now share the daily and historical usage reports with the university and show changing usage trends and how we're conserving resources and managing available bandwidth strategically," he said.
FlowCommand has also helped augment SDW's security posture, said Soh. The solution will help identify problems early and mitigate them rapidly.
"This granular, real-time network visibility and control has also helped the service provider troubleshoot and resolve network issues more quickly," he said. "FlowCommand's ease-of-use and intuitive interface are also really appreciated by our operations staff."
