Overcoming SD-WAN Adoption Challenges and Deployment Issues

Due to developments such as ever-increasing numbers of business applications competing for network resources, growing network traffic demands and enhanced network flexibility requirements, the networking needs of organisations both public and private are becoming more and more complex. In particular, the problems organisations are facing with digital transformation and migration of critical applications to the cloud cannot be solved with legacy enterprise WAN solutions. SD-WAN has evolved to address those challenges. Most organisations are by now aware of the benefits that SD WAN delivers but as it is a new and rapidly evolving technology and often outside many organisations’ expertise, the practicalities often put deploying a solution on hold. The SD-WAN concept is simple in principle, i.e. deliver the optimum connectivity experience to sites, users and devices in accessing network resources and services unconstrained by access mode or location. However, successful SD-WAN project implementation throws up many challenges and gives rise to several considerations in deciding which products and service delivery models are best suited to an individual organisation’s business needs. SD-WAN Adoption While not universally applicable, SD-WAN can meet the changing requirement of most enterprise organisations as demands on the network grow. Key to a decision to adopt SD-WAN is a review of the business considerations that are driving the change and the focus should be on what problems and business outcomes is the SD-WAN platform expected to address. Considerations include: What is the organisation structure and footprint – are there several branch offices, sites and remote users accessing network resources? Is the business on or about to embark on a digital transformation? Are business critical applications and... read more

Features and Benefits of SD-WAN

In the first post in this series we looked at the various drivers for SD-WAN adoption and the factors that are influencing decisions that companies are taking as they move to take advantage of this new technology. But how exactly does SD-WAN address some of the requirements that we highlighted previously, what are the key features and ultimately what are the main benefits that an organisation adopting SD-WAN should expect to see? To begin with, we should acknowledge that there are many different SD-WAN solutions available in the market and while sometimes differing in terms of focus and terminology used, they are all aiming to address essentially the same demands from companies at the various stages of  digital transformation. While differences exist, there are a core set of capabilities and related benefits that leading SD-WAN solutions comprise as follows: Centralised Control At the core of an SD-WAN is a centralised control or Orchestration platform which provides the configuration and management of the SD-WAN. Centralised control is key in terms of realising the SDN principle of separation of the control and data planes, effectively abstracting the underlying connectivity regardless of type (fixed or wireless), removing any related dependencies that would otherwise exist and providing the freedom and flexibility to architect a set of virtual overlay connections in the manner best suited to business needs. It is these overlay connections or tunnels that then allow the SD-WAN to provide the required flexibility and visibility needed in modern networks. Packet Recognition and Steering The ability to recognise traffic on a per packet basis and to then steer this traffic across the preferred... read more

SD-WAN Drivers

This is the first of our new series of posts focussed on addressing the main questions we receive from customers about SD-WAN. Over the coming weeks we will address the most important reasons for choosing SD-WAN and the main considerations for deployment based on our own and customer experiences. To begin with, we look at what is motivating companies to choose SD-WAN. One of the main drivers for SD-WAN adoption today is the move to take advantage of cloud based services, both Software and Infrastructure as a service. Many companies both large and small have or are about to embark on a digital transformation journey and for most that means a very significant shift to cloud hosted applications and workload. What that also means however is that the traditional wide area network, commonly architected on a hub and spoke basis, is no longer  capable of dealing with the demands being placed on it. Failure to address this issue can result in poor application performance and ultimately, a poor user experience. The traditional network was designed to carry traffic from remote or branch locations back to a central site, a data centre or HQ, where applications were hosted or from where traffic could be safely forwarded. Modern environments place both applications and workload in many different locations meaning that the traditional network is no longer optimised to deal with the demand. Compounding this, the volume of applications in use is growing continuously and the requirement to optimise the network on a per application basis is therefore critical to meet the need of the modern enterprise. These fundamental changes mean that... read more

Supporting a remote workforce with SD-WAN

With the move to working from home and the growing expectation that in many cases this is likely to remain a reality for many employees for the foreseeable future, more and more companies are looking at ways to improve connectivity issues and in turn ensure security for remote workers. In recent weeks many of our customers have started expanding existing SD-WAN deployments or adding SD-WAN as a secure and reliable way to improve the experience for both customers and employees when communicating from a home office environment. Traditionally remote office environments don’t have any quality of service and cannot offer priority to those applications that need it. Congestion mitigation is typically not available and in many cases the performance of consumer broadband can be very variable. SD-WAN can solve these issues, even when only a single link is available and can provide reliable cloud connections and the ability to apply policies and in turn assure application performance. Critical services such as the use of SaaS and IaaS based applications, video conferencing and the increased use of VoIP, in particular for customer facing staff, require more than standard VPN, they require SD-WAN. At Iricent, we are working with partners and with customers to help with this transition to remote working and are happy to offer free trials combined with professional services support to allow customers to learn for themselves the benefits of SD-WAN for remote working. If this sounds interesting, contact us at remote-working@iricent.com to schedule a call or a... read more

Iricent Launches Managed SD-WAN Services

Iricent recently launched a cloud based Managed SD-WAN Service targeted at Service Providers who wish to have access to a white label services platform. Software Defined WAN (SD-WAN) is a specific software-defined networking (SDN) technology use case applied to WAN connections which is rapidly gaining interest and seeing increased adoption in enterprise networks as it offers many advantages over traditional, fixed Wide Area Networks. SD-WAN architecture uses SDN principles to separate the data plane from the control plane in the WAN. It abstracts the underlying transport networks (MPLS, broadband internet, wireless, satellite) and shifts control intelligence from customer premises equipment (CPE) or edge devices to a centralized controller and in turn delivers many benefits including: All-in-one solution (WAN optimization, policy based control, application prioritisation, …) Lower cost for VPNs Access flexibility and redundancy Works over a variety of media (MPLS, Broadband Internet, LTE, satellite) Dynamic path selection and load sharing across WAN connections Simplifies the branch network making it easier to manage with increased network agility ZTP – Zero Touch Provisioning For service providers, SD WAN provides a unique opportunity to broaden the existing service offerings independently of existing reach and without the need for additional. Barriers to entry for new SD WAN services are significantly lower as SD WAN is an OTT offering and a service provider can offer customised SD WAN services that are tailored to specific use cases such as real time traffic or are further enhanced with cost effective WAN Optimisation for example. Iricent SD WAN At Iricent, our platforms are designed and delivered to allow providers to offer SD WAN services as cost effectively as possible... read more

Iricent at Mobile World Congress 2018

  Less than one week to go now to MWC 2018 in Barcelona and along with catching up with customers, partners and even friends, we’re looking forward to catching up with all that’s new in the telecoms world. Expect to hear lots of 5G announcements and plently of IoT, artificial intelligence and machine learning details over the week from 26th February – 1St March, all of which we expect will drive an even more accelerated rate of innovation across all walks of industry and life in general over the coming years. Of course central to all of this, and to the congress itself, is the network and at Iricent that’s the part that we are mostly interested in. Over the course of next week, we will be particularly interested to learn about new network developments being introduced both in relation to platforms and services, almost all of which take advantage of the increasing adoption of both SDN and NFV technologies as these become increasingly central to network and services deployments.
