How Should You Be Thinking About Your WAN?

For a twenty year period that began in the mid-1980s the enterprise WAN went through a series of transitions, starting with Time Division Multiplexing (TDM) based on T1 access and then moving on to Frame Relay, ATM, and finally to MPLS. Unfortunately, over the last decade there hasn’t been a new transmission service introduced into […]

Internet Connections Can Be Used For More Than Best Effort Traffic

The topic of WAN transformation is certainly nothing new, but the shift to mobile and cloud computing is making the evolution of the WAN something businesses must make a priority. Prior to being an analyst I ran some fairly large WANs, and for as long as I can remember there has been talk of trying […]

Riverbed Admits Scaling Limitations

Riverbed and Silver Peak don’t usually agree when it comes to matters of WAN optimization scalability and for good reason. We’ve offered it; Riverbed hasn’t. But now in a recent blog, Riverbed has decided to tell us why its products don’t scale. Apparently, it’s because they’re like lattes. Let me explain. There’s been this misconception […]

Net Neutrality: Don’t Bet Your Business Against It

Net Neutrality: A Force To Be Reckoned With OTT (Over-the-Top) content (notably video) on the public Internet continues to tie up yet more of the public Internet capacity. Infrastructure providers, however, are wary of investing heavily in new infrastructure capacity since with net neutrality they have little chance of monetizing these investments. On their side, […]

The Global Continuity Network

Business continuity is the new Holy Grail. Where once people used to look to ‘rapid’ backup and restore capabilities to recover from a disaster, this is no longer good enough in many cases. Backup windows are commonly insufficiently long to carry out the required actions of moving large data sets from one place to another, […]

Wake Up Your Redundant WAN Link

Many enterprises I speak with are looking to leverage low-cost, Internet lines for backup or even to offload traffic from more expensive MPLS connections. The Hybrid WAN, as this approach is called, is too complex to be built with conventional routing. Here are the three steps you can follow to build a Hybrid WAN in […]

Extending VMware vSphere 6 Replication over the WAN

Data protection is essential for business continuity and disaster recovery, and that includes the protection of virtual machines (VMs). Today at VMware Partner Exchange 2015, Silver Peak announced that our WAN optimization software has tested and pre-validated the new VMware vSphere® 6 Replication solution to accelerate remote replication. VMware vSphere 6 Replication provides an efficient […]

MPLS or SD-WAN: A Systems Engineering Analysis

Southernitman, a self-identified IT manager on Reddit, recently posted his dilemma on choosing between MPLS or an SD-WAN solution, commonly referred to as WAN Virtualization. Here’s how I thought he and anyone else considering MPLS should analyze the technology. THE QUESTION Southernitman said on the Reddit forum that he was looking at upgrading the connectivity […]

The Software-Defined WAN and WAN Optimization: Networking’s Dynamic Duo

Today’s WANs have become remarkably complex. What used to be relatively straightforward point-to-point links have multiplied, meshed, and hybridized, as well as gaining layers of management and optimization to overcome the inherent weaknesses of telco connections and wring more capacity from them. At the same time, more and more users and services are moving off […]

Speeding up Network Provisioning

You probably know the problem already. The business is opening up a new office; has acquired a new company or wants to move a group of people from Place A to Place B. They have finally got around to letting IT know that it will happen – and they want you to wave your magic […]
