DVPN

Cloudvpn 1 Cloudvpn is an open-source, mesh- networking capable communication tool. It differentiates itself from other VPNs by serving as a generic transport layer for any packet-based data traffic, which can include traditional VPN purposes, but is easily extensible to any other kind of traffic.

Cloudvpn - Capabilities 1 Cloudvpn tries to establish a decentralized transport network, routing through which is done using an optimized DVR-like algorithm. This gives the "cloud" of nodes a great potential, allowing simple failover of connections and traffic route optimalization.

Cloudvpn - Capabilities 1 Cloudvpn is designed as a set of tools. Every node runs a 'cloud' program, which provides an encrypted connection and mesh routing capabilities, and then attaches various other 'mesh clients', that communicate using the pre-created network. For example, 'ether' tool creates a virtual Ethernet interface and routes its traffic through the mesh, giving the transport Ethernet-VPN capabilities.

Portable Network Graphics - DEFLATE optimization 1 However, advpng doesn't have an option to apply filters and always use filter 0 globally(i.e. unfiltered), therefore it should not be used where the image benefits a lot from the filtering. advdef from the same package, on the opposite, doesn't deal with PNG structure and acts only as a re- deflater, virtually keeping the filter settings.

Portable Network Graphics - DEFLATE optimization 1 advpng doesn't have an option to apply filters and always uses filter 0 globally (leaving the image data unfiltered); therefore it should not be used where the image benefits significantly from filtering. By contrast, advdef from the same package doesn't deal with PNG structure and acts only as a re-deflater, retaining any existing filter settings.

Portable Network Graphics - Wrapper tools 1 An open source Windows program called [ hp?page=FileOptimizer FileOptimizer] losslessly optimizes many filetypes, including PNG. It runs multiple PNG optimization programs: advpng, apngopt, optipng, PngOptimizer, pngout, pngrewrite, and pngwolf.
