Virtualized Evolved Packet Core (vEPC) is a major breakthrough in network function virtualization (NFV). When
asked where they have deployed NFV in production networks, communication service providers (CSPs) consistently name vEPC as one of the top answers. Why is that?
In order to maximize their processing capacity, CSPs virtualize a subset of their network applications, including
mobile edge computing (MEC), base stations (small/macro
cells) and the mobile core, because these systems use a
The mobile packet core builds the foundation of the core
network on which mobile CSPs offer IP-based services to
their customers. Implementing vEPC solutions can help
CSPs obtain the scale necessary to accommodate growing
numbers of subscribers and large amounts of traffic or
connections while controlling costs and improving on quality of experience (QoE). In the past, evolved packet core
(EPC) solutions were deployed on purpose-built hardware.
NFV enables operators to deploy EPC c
At a projected market of over $4B by 2010 (Goldman Sachs), virtualizationhas firmly established itself as one of the most importanttrends in Information Technology. Virtualization is expectedto have a broad influence on the way IT manages infrastructure.Major areas of impact include capital expenditure and ongoingcosts, application deployment, green computing, and storage.
The idea of load balancing is well defined in the IT world: A network device accepts traffic on behalf ofa group of servers, and distributes that traffic according to load balancing algorithms and the availabilityof the services that the servers provide. From network administrators to server administrators to applicationdevelopers, this is a generally well understood concept.

This white paper reveals how Cisco’s Threat-Centric Security Solutions for Service Providers delivers consistent security policy across physical, virtual, and cloud environments by combining the power of open and programmable networks with deep integration of Cisco and third-party security services.
Edison has followed the development and use of Cisco’s Application Centric Infrastructure (ACI) over the past five years. Cisco ACI delivers an intent-based networking framework to enable agility in the datacenter. It captures higher-level business and user intent in the form of a policy and translates this intent into the network constructs necessary to dynamically provision the network, security, and infrastructure services.
Enterprises are looking to innovations like big data, cloud-based services and mobile apps to improve decision making and accelerate business results. But legacy IT implementations—independent compute, storage and networking platforms, veneered with a hypervisor— often can’t deliver on the increased agility, scalability and price performance demands of this new era of IT.

Cisco engaged Miercom to conduct a competitive analysis of its Catalyst 2960-X switch versus two comparable Hewlett-Packard switches from the 2920 and 5120 product families. Miercom executed comprehensive hands-on testing and evaluated the performance of some widely deployed features that are critical for reliable functioning of enterprise networks. The test methodology focused on specific areas in which Cisco believed there were key competitive differentiators between the products. Test results validated include throughput, latency, energy efficiency, stacking, LACP load balancing and Quality of Services (QoS) performance. Miercom found that the Cisco Catalyst 2960-X demonstrated superior performances against the competitive switches in the tests featured in this report.

We have now strengthened the scope of our Unified Computing System by expanding our data centre management capabilities. Download your free white paper and learn how we have become the key supplier of converged technology and services in this space.
A related recent development in the data center is converged infrastructure (CI). Instead of the traditional silo deployment approach to storage, compute, and network resources, all infrastructure elements are delivered and managed in a single environment, providing virtualized access to business services in an efficient manner. This is particularly suitable for cloud-based delivery models. However, since CI achieves lower costs through optimization of data center resources, it can be effective for all IT organizations, regardless of the way in which the services are managed or presented.
There are a number of factors contributing to the growing popularity of streaming live events or offering content on demand, from anywhere, any time, on any device. Live streaming major sporting events such as the Superbowl or the Olympics is now a viable alternative to broadcast TV. And as Limelight’s 2017 State of Online Video report reveals, the average number of online viewing hours is almost six per week. However, as viewer expectations continue to rise, keeping audiences happy and engaged isn’t easy.
In this white paper we discuss current trends and what to expect in 2018. We examine the role Content Delivery Networks (CDN) can play in optimizing the delivery of online video content at global scale, and the technologies available to ensure the lowest latency delivery possible.

Most organizations are in the midst of some form of digital transformation (DX),
transforming how they bring products and services to the market—and ultimately
deliver value to their customers. But DX initiatives also bring complexity for the
network operations team. With business-critical services distributed across
multiple clouds, this leads to potential performance issues, especially at
Given these realities, it is no wonder that software-defined wide-area network
(SD-WAN) technology is rapidly going mainstream. Unfortunately, SD-WAN is an
example of the paradox of DX: transformative technology can potentially move the
business to the next level, but the expanded attack surface it creates can expose
the organization to significant risk. That is why an SD-WAN deployment, like every
other DX effort, should be accompanied by a security transformation (SX) that
rethinks outdated principles, broadens protection beyond the data center, and
integrates the security archit

organizations to look elsewhere for a more effective
network solution to address distributed traffic across
remote sites and branch offices.
Some of the specific issues organizations face with
their traditional WANs include:
- High total cost of ownership (TCO)
- Lengthy provisioning cycles
- Performance degradation with the growth of cloud
- Inadequate redundancy and resiliency
- Lack of application-aware connectivity
To better manage WAN investments, enterprises are
adopting a new approach for their distributed branch
office networks. Software-defined WAN (SD-WAN)
offers improved performance, agility, and operational
flexibility plus significant cost savings. But not all SDWAN
solutions are created equal.
When it comes to securing all the parts of a modern distributed network, endpoints remain
the most vulnerable outlier. Mobility has brought a flood of different devices that cross in and
out of enterprise networks on a daily basis. This public exposure, combined with inadequate
traditional endpoint security and a high degree of user autonomy, makes these devices
prime targets for malware infections and other forms of sophisticated attack that seek to
exploit the broader organization. And threat actors are finding enormous success along
To stay competitive, most organizations are currently embracing digital transformation
(DX)—including cloud services, smart Internet of Things (IoT) devices, and greater mobility.
These adaptations provide organizations with faster and more seamless access to critical
information, regardless of the device being used to access it. However, as distributed
networks expand and become more difficult to manage, the endpoint remains a weak link i
The cloud is a network of servers housing data, software, and services. Cloud services are commonly accessed via the Internet, instead of locally in a data center. Businesses are increasingly relying on the cloud for cybersecurity for two key reasons: 1. Due to a changing threat landscape, there’s a need for more scale, accuracy, experience, and collective intelligence. These resources are out of reach internally for most organizations. 2. There are fundamental limits with on-premises hardware mitigation appliances and enterprise data centers for Distributed Denial of Service (DDoS) and web attack protection.
