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.

Hospitals and health systems around the globe are looking at everything from tighter supply controls to energy efficiency initiatives as ways to cut costs and save money. Another avenue being evaluated more closely is communications.
This paper illustrates how Cisco Open Network architecture for service providers supports the software-driven applications, cloud capabilities, and business models that help you seize opportunities and get ahead.
Interconnecting three or more sites across a metro or wide area network has traditionally been accomplished via a hub and spoke network topology using Private Lines, Frame Relay or IP VPNs over the Internet. Ethernet services support hub and spoke topologies but also support an “any-to-any” network topology similar to a LAN but delivered over a wide area. This latter capability is unique to Ethernet services and cannot be cost effectively delivered using legacy point-to-point technologies such as Frame Relay or IP VPNs.
This paper discusses two options for multi-site connectivity using Ethernet services. One option discusses the classical hub and spoke topology using Ethernet Virtual Private Lines (EVPL). The other option discusses the “any-to-any” topology using an Ethernet Private LAN (EP-LAN) service. Through examples, the paper illustrates the capabilities of the two approaches and their benefits.

Data connectivity has long been a necessity for enterprises big and small, as has the need to use that connectivity to extend enterprise Local Area Network (LAN) across networks. But the process of building an enterprise Wide Area Network (WAN) is anything but easy.
Examine the three broad challenges that Financial Services Institutions (FSIs) face today: compliance and risk management,
consolidation and innovation. To address these effectively, FSIs require an Information and Communication Technology (ICT) infrastructure that offers both the security and reliability of their legacy communications systems as well as the flexibility and scalability that new generation networks provide, in order to adapt and innovate in the highly competitive financial services environment.
There are now a variety of alternatives when it comes to connecting multiple sites with WAN links. Multi Protocol Label Switching is fast gaining popularity for many businesses as their preferred choice when it comes to creating a Virtual Private Network (VPN) over WAN. This paper will discuss the differences between MPLS and IPSec, and the benefits achieved from migrating to MPLS.
The process of subnetting is both a mathematical process and a network design process. Mathematics drives how subnets are calculated, identified, and assigned. The network design and requirements of the organization drive how many subnets are needed and how many hosts an individual subnet needs to support.
IT departments are jazzed about cloud services, which promise fast deployments and major cost savings. But is the cloud actually delivering on these promises? Now that more enterprises have cloud experience under their belts, IDG Research Services decided to find out.
