IP is a network layer protocol in the internet protocol suite and is encapsulated in a data link layer protocol (e.g., Ethernet). As a lower layer protocol, IP provides the service of communicable unique global addressing amongst computers. This implies that the data link layer need not provide this service.
The Digital Security and Surveillance eZine is about channel partners extending their expertise in Internet Protocol to a whole new arena. For these partners, security goes well beyond software, firewalls, VPNs and other security offerings commonly discussed in the industry. These partners are combining networks, storage, cameras and similar technologies into full solutions designed to help protect the customer.
Whether you are starting a new business or expanding your existing business, you will need to choose a business phone system that meets your organisation’s requirements. This guide provides you with essential information and tools so you can understand your options, and make the decision that meets the needs - and ambitions - of your business.
As the digital universe evolves in both volume and scope, companies must be diligent about protecting their content. Fortunately, companies can easily leverage IP information to protect themselves. This paper explores the best practices of using IP intelligence for digital rights management to reduce risk to online content.
To enable always-on application access and business connectivity, you need a rock-solid network foundation. The increasingly complex, dynamic and fluid relationship between networks and devices requires a new approach to IP Address Management (IPAM) – one that unifies mobile security, address management, automation and self-service to provide actionable network intelligence and a broad span of control. This paper discusses the critical role of IPAM in providing a smarter way to connect mobile devices, applications, virtual environments and clouds.
"VM performance is ultimately determined by the underlying physical hardware and the hypervisor that serves as the foundation for your virtual infrastructure. This foundation has become simpler over the years, but there are still several areas that need to be fine-tuned to maximize the VM performance for your environment.

When rack-mounted servers first appeared on the scene in the 1990s, they offered considerable advantages over the behemoth boxes they replaced. Their small, standardized footprint went a long way toward making data centers easier to manage. In the ensuing decades, form factor size and compute power have had an inverse relationship.
Their universal standardization earned them the nickname “pizza box” servers, and it was a key driver of the scale-out computing model popular in the early 2000s. Populating a rack of eight servers and either clustering them or implementing failover from one to the other was far easier than previously possible.
Virtualization was supposed to be the disruptive technology that saved IT. The cost savings from consolidation and the ease at which applications can be deployed promised to vastly improve delivery of IT services, free up IT staff to work on other projects, and not strain budgets.
Unfortunately, lack of insight into IT resource status in highly virtualized environments and the complexity of the interactions between server, storage, and network elements have added to IT staff manual workloads and led most companies to dedicate too much time to operations and not enough time to innovation. This basically negates the major benefits of virtualization.
