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. 

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. 

This resource explores an innovative, market leading mobile security solution that mitigates the risks associated with deploying IP-based services. 

Check out this white paper to learn about two network protocol models, TCP/IP and OSI. 

Forward error correction (FEC) technology protects against network packet loss. Content delivery solutions using FEC have numerous user experience and cost advantages. This paper provides a technical overview of RaptorQ, the best available application-layer FEC technology. 

Gain a deeper understanding of current networking issues and how they are related to the evolution of computer networks. In particular, examine how administrators have dealt with switching bandwidth from WAN to LAN with FabricPath. 

Typical IT departments feature islands of isolated infrastructure, leading to inefficient use of servers. The "application grid" concept allows data centres to run more efficiently, using less hardware and less software. This paper explains. 

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. 

Overlay transport virtualization (OTV) can help solve many of the challenges in today's increasingly virtualized and geographically dispersed data centers. Access this paper for a high-level overview of this technology and how it differs from the alternatives. 

A new approach to Business Process Management (BPM) is the use of BPM and SOA together in a layering strategy. This white paper explores the BPM layered concept and offers a case study of how ABN AMRO, one of the world's largest financial institutions, has benefited from its deployment. 

This paper documents the file storage challenges users face and how the HP StorageWorks X9000 systems help organizations address and overcome storage performance, density, management, cost, and deployment issues. 

Cloud infrastructure platforms like VMware vSphere 4.0 can benefit from load balancers that connect users to the most suitable datacenter. This white paper outlines how the Riverbed Stingray Traffic Manager Virtual Appliance (VA) improves traffic performance compared to a Linux install. 

Read this white paper and trace the steps to a successful converged network infrastructure. By identifying today's most important IT trend - virtualization - you'll be on your way to implementing HP supported technologies to enhance your virtualized computer networks.
