WHITE PAPER - With IP there are two Link-State protocols in use OSPF (Open Shortest Path First) and IS-IS (Intermediate System to Intermediate System). Both work in much the same way, but OSPF is more commonly used. This white paper examines OSPF synchronization.

WHITE PAPER - 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.

WHITE PAPER - Every routing protocol has some pros and cons and its own metric considerations. In this white paper, we will discuss Enhanced Interior Gateway Routing Protocol (EIGRP), a Cisco-proprietary routing protocol.

WHITE PAPER - 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.

WHITE PAPER - Border Gateway Protocol (BGP) is a very complex routing protocol where the administrator can influence the route choice in more ways than with an interior gateway protocol. This white paper will provide you with a high level overview of interdomain routing with BGP.

WHITE PAPER - In this white paper, we are going to discuss the application of QoS to networks with media flows installed within them, such as voice and video. We'll see that it is very unnatural for voice to even exist on a data network, because it was never designed to do so.
