From packet inspectors to WAN optimizers, network add-ons are all the rage
These days, it seems like a dozen new network “extras” – including traffic monitors, packet inspection technologies and management products, to name just a few – are launched every week, all advertising large-scale gains in performance, security and ease of use.

But why is this glut of network-centric add-ons happening now?
The rapid swelling in the number of ancillary products designed to make modern business networks work more efficiently may be, in large part, a consequence of a major shift in the way companies use those networks.
“Traffic flows, especially in the data center, have shifted fairly dramatically over the last five to seven years,” says Abner Germano,w Juniper Networks’ director of enterprise marketing.
The continuing transition away from the client-server model of computing, in the business world, means that the existing tree-like architectures used to service complex networks are increasingly inefficient, he says.
“The networking industry has been growing extremely rapidly for the last 20 years. But in the enterprise, the time from 2000 to 2009, a lot of people standardized on Cisco. In many ways, that was the right decision to make at the time,” Germanow says.
His colleague, senior product marketing director Dhritiman Dasgupta, says that shifting traffic patterns have made parts of the consequent network structure redundant, however.
Paving the way for the flat network
So-called “flatter” networks, unburdened by the older multi-tiered model, “are at the heart of cloud computing,” he states. The rapid growth in Ethernet speeds – from 100Mb to 1Gb to 10Gbps and so on – also helped to create new capabilities, while simultaneously exacerbating architectural concerns.
Past a certain point, however, simply adding fatter pipes in order to boost performance becomes vastly less economical than restructuring the way the network handles traffic.
According to Germanow, this changing value proposition is substantially disruptive to the market. Therefore, many seek to apply existing technology to new problems, often without a thorough understanding of what they’re doing.
“There are a lot of people running around with hammers going ‘that’s a nail,'” he says.
Confusion
Rick Tinsley, CEO of WAN optimization provider Silver Peak, says a lot of the new network products are focused on web traffic and cloud technology.
“These areas often get confused. And, frankly, a lot of the analysts in the early days predicted that the [application delivery controller] market … and the WAN optimization market would ultimately merge. That absolutely has not happened,” he asserts.
