The Remote Access Conundrum Part 2: Tunneling at Layer Two

Overview To offer a successful remote access VPN service, an ISP must master many challenges, ranging from trouble-free client software installation to back-end user database integration. L2TP is a standard method for tunneling PPP across the Internet or any intervening IP or non-IP network. Unlike IPsec, L2TP was designed specifically to support traditional remote access. L2TP creates a "virtual modem connection" from a dial-up client to an enterprise network. Physically, an L2TP access concentrator at the provider’s POP terminates the client’s call.

Convergence: lower costs and extra flexibility - the IP VPN promise

An SSL session can therefore be set up from a PC anywhere, much more cheaply then an IPSec IP VPN, in a hotel room, an internet café or from a wireless hotspot. So do the remote access market arguments for SSL and IPSec IP VPNs stand up in the MPLS...

What are IP VPNs good for?

While acknowledging IPSec's role in supporting users at satellite offices, BT's Logan says the bulk of big corporate network users are plumping for an MPLS IP VPN, perhaps because it handles voice so well thanks to its prioritisation capabilities.

High Level Best Practices in Software Configuration Management

When deploying new software configuration management (SCM) tools, implementers sometimes focus on perfecting fine-grained activities, while unwittingly carrying forward poor, large-scale practices from their previous jobs or tools. The result is a well-executed blunder. This paper promotes some high-level best practices that reflect the authors' experiences in deploying SCM.
