This paper  examines the big picture when it comes to Multiprotocol Label Switching (MPLS), and what happens when a data packet traverses an MPLS cloud. 

MPLS is a foundational technology that allows service providers and enterprise architects to offer state-of-the art networking to their customers. 

In this transcript, senior enterprise IT architect Nelson Ruest breaks down the seven different layers of the server virtualization architecture, and explains the role the hypervisor plays in the success of that infrastructure. 

Is your data safe in the cloud? Explore this resource to compare public, private and hybrid cloud computing approaches, and discover the 4 layers of cloud security that ensures that your data is protected from unauthorized access. Learn what critical security features you should look for in a cloud provider. 

In this white paper, we'll take a look at access control lists, often referred to as access lists or ACLs (sometimes pronounced "ackels"). 

For many years network administrators have expected security breaches to come from outside an organization or at the upper layers of the OSI model. This paper will focus on securing layer 2 switching at the access layer through port security and preventing denial of service (DoS) attacks at layer 2. 

Data abstraction overcomes data structure incompatibility by transforming data from its native structure and syntax into reusable views and data services. But some data abstraction approaches work better than others. Composite data virtualization is an optimal way to implement an abstraction layer at enterprise scale. 

Any virtualization layer or hypervisor introduces a new set of demands to a server or blade environment. This e-book explains the process of virtualizing the I/O layer, how to manage it and what challenges remain for this disruptive technology. 

How does WAN Op work to maximize bandwidth, overcome congestion, autocorrect for out-of-order packets, reduce application and protocol chattiness, and, most magical of all, mitigate the negative impact of latency caused by the sheer physics of distance? 

This paper outlines the things you must consider when thinking about the feasibility of replacing a WAN provider’s provider (P) and provider edge (PE) devices with routers. This paper examines these considerations in greater detail, to see where any potential problems might arise.
