Hierarchical Provisioning Algorithm for Virtual Private Networks Using the Hose Model

Tags:
infrastructure management

Overview Virtual Private Networks (VPN) provides a secure and reliable communication between customer sites over a shared network. Two models were proposed for the service provisioning in VPNs. The "Hose model" for VPNs alleviates the scalability problem of the "Pipe model" by reserving bandwidths for aggregate ingress and egress requirements instead of between every pair of VPN endpoints. In this work, VPN endpoints are connected using a tree structure and the algorithm optimizes the total bandwidth reserved on edges of the VPN tree. This paper introduces a fast and efficient algorithm in finding the shared VPN tree to reduce the total provisioning cost.

MPLS: The icing on the networking cake?

There are three main functions of MPLS, quality of service, traffic engineering - which includes a unique ability to re-route traffic very quickly in case of network failure - and enabling virtual private networks (VPNs).

Managing convergence - the key points every company should know about

Traffic on virtual private networks (VPNs) is commonly encrypted for transmission between sites but companies have to be aware that the QoS offered by a VPN often will not match up to the QoS support offered by the LAN switch.

IP over everything?

Granted, this sort of approach is unlikely to offer the same rapid basic service provisioning and bandwidth upgrade times as the sort of service Neos Networks offers. We've already launched our IP VPN QoS network and that is connected using SDH...

What's the bottom line value of IP?

In theory, swapping out old 64k Frame Relay leased lines for new IP connections offers greater bandwidth flexibility at cheaper underlying prices, as well as a host of new services such as IP VPNs, IP storage and videoconferencing.

Secure remote access - the way to go

While SSL may prove more flexible and cheaper to deploy than IPsec VPNs - which typically require a company to own the laptop so they can manage the VPN client - they are by no means cheap. Acknowledging the incessant march of SSL VPNs - which use...

Live Webcast: Telecoms 2.0 - Where is telecoms heading?

In this webcast, our panel of experts will review where we are with next generation telecoms in the UK, working through the concept of 'Telecoms 2.0': - Realising the potential of Next Generation Networks - why it isn't just about the technology? - What attributes should firms be looking for in their telco partner? - Is the relationship between telco provider and customer changing? - What things need to happen to make next generation services a reality? - You say you want the supplier to change. Do you want to change too? - What is Telecoms 2.0?

Telecom 2.0: Mind over matter

ntl:Telewest Business believes that the role of the telco is evolving. Gone are the days when it was enough to simply focus on circuits and minutes, customers now need a far higher degree of interaction and look for suppliers who will talk business solutions with them.
