Our 2013 IT Impact Survey highlighted the importance of collaboration between business leaders and IT as trends like BYOD, data center consolidation and Cloud applications put more pressure on the network. Why collaborate? The survey highlighted that 34% of application roll outs over the prior 12 months were delayed because of not enough budget. You would think that if applications were a priority IT would be given sufficient budget to make sure the network was ready to handle the extra traffic. Unfortunately, according to Nemertes, most organizations’ WAN budgets will remain flat or decline in 2015, meaning that adding bandwidth is often not an option for IT. So how can you do more with less?
Network customers have always bought networks for one and only one reason: to run their applications over them. Yet for most of that time, those networks have been largely oblivious to the composition of the network traffic they carried. Traditional network tools could tell you whether your network was having a lot of errors, or whether a given link or interface was congested, but they couldn’t tell you what was congesting your network, beyond the limited granularity of a few well-known ports. Finding out that you’ve got a lot of HTTP or HTTPS is not very helpful in finding out whether you’re swamped by personal traffic that needs to be controlled, or by legitimate business traffic that requires an increase in effective bandwidth.
These are just a few of the many questions that were asked on the webinar ‘How to Deliver Uncompromising Branch Application Performance‘:
- Would DMVPN also allow me to easily integrate networks using multiple MPLS providers?
- Is there a specific router model, IOS required for a PfRv3 branch controller and master controller?
- Can you explain how the direct spoke-to-spoke routing is accomplished when using DMVPN?
- Is using BGP with DMVPN scalable? Wouldn’t we have to define each neighbor?
Over the past few weeks I’ve had the chance to come up from my rabbit hole of deployment projects and catch up on the tech news. In particular, the announcement at Interop New York where Cisco announced the new ISR 4400 family of routers along with a few other articles got me to thinking about how far branch office connectivity has come in the past decade or so and to a question: is one method of branch connectivity better than another?
In the Beginning…
In the past decade or so we have seen substantial change in how we connect to the internet and how fast we do so. Early on (circa early 2000s) the internet was fairly flat. Real time voice and video were still a thing of science fiction. In the enterprise we connected remote offices back to the central office via leased lines over a frame relay network. T1s were considered good and if you had a DS-3 link you must have been in a big IT shop. Compute services were limited to corporate email (Outlook/Exchange were the new kids on the block) and client/server based systems. Read More »
If you have been following Cisco Blogs, attending CiscoLive, or reading industry publications like Network World, you’ve probably heard about Cisco’s Intelligent WAN or IWAN solution. For those of you that haven’t been in the loop, have more questions, or are just plain curious about the Intelligent WAN, we have a short webinar series kicking off on the 6th of November at 10am PST. We will cover the important building blocks for architecting your hybrid WAN infrastructure including:
- Defining the Hybrid WAN
- In-depth technical analysis of Cisco’s Hybrid WAN Solution: IWAN
- How IWAN can help to lower your IT costs
If you belong to an IT organization that is centralizing applications in the public or private cloud to gain efficiencies or are migrating the Internet edge in your branch offices to take advantage of software as a service (SaaS) applications, then make sure you attend this live 60-minute webcast, the first of a four-part series. We will show you how a hybrid WAN architecture can help you deliver a consistently high-quality end-user experience while actually reducing your WAN operating costs.
Still not sure if IWAN is for you? Consider these other trends that might be happening in your enterprise network today that could end up causing many sleepless nights in the future:
- Mobile devices continue to proliferate, and high-bandwidth applications such as video are becoming more and more commonplace, putting pressure on the WAN.
- According to Nemertes, most organizations’ WAN budgets will remain flat or decline in 2015, meaning that adding bandwidth is often not an option.
