PPP

Purchasing Power Parity

The theory stating that, in an efficient market, the exchange rate of two currencies results in equal purchasing power. That is, if one pound is worth two dollars, one pound in England should buy the same amount in goods and services that two dollars can buy in the United States. Fixed exchange rates, taxes, and other inefficiencies are thought to disrupt purchasing power parity. Some theorists believe the idea holds most true when comparing countries or regions with similar standards of living.

Cabletron also announced significant VPN enhancements to its current line of SSR 100, 200 and 500 SOHO and branch office routers to support secure VPN tunneling based on IPSec and L2TP. Cabletron is unique in the industry in that its products can deliver VPN solutions over all major "last mile" access technologies, including cable, xDSL, PPP, Frame Relay, ISDN and wireless connections.
SSR 100/200 VPN software: IPSec & L2TP with DES $195 Sep.
Caracteristicas: Estandares 802.11 b/g y 802.11 draft n; velocidad de hasta 300 Mbps, switch de cuatro puertos 10/100/1000 Mbps LAN; soporte de protocolos PPTP, L2TP e IPSec; tecnologia MIMO, firewall, puerto DMZ, seguridad NAT y para Syslog (SPI o Stateful Packet Inspection), DoS, IDS yWDS; servidor de impresion multifuncion e interfaz de gestion a traves de Internet
However, vendors have combined PPTP with a similar protocol, Cisco Systems' Layer 2 forwarding protocol, to create L2TP, which supports multiple, simultaneous tunnels for a single client.
The Interworking Function within its Total Control access platform now supports the L2TP and PPTP tunneling protocols, extending the reach of wired VPNs to mobile workers.
Caracteristicas: Estandares 802.11 n Draft 2.0 y 802.11g; un puerto WAN y cuatro Ethernet 10/100 Mbps; tecnologia de multiples entradas y multiples salidas (MIMO), con 2TX/2 RX; protocolos paraADSL PPPoE, PPTP y L2TP; soporta WPA-PS K, WPA2-PSK, WPAy WPA2; incluye dos antenas inteligentes internas.
L2TP con IPSec, cliente DCHP y PPoE, servidor DHCP, alta disponibilidad 60 zonas de seguridad virtuales, 8 ruteadores virtuales, hasta 150 VLANs.
The leading tunneling protocols are: SOCKSv5, Point-to-Point Tunneling Protocol (PPTP), Layer 2 Transport Protocol (L2TP), and Internet Protocol Security (IPSec).
SEGURIDAD: Inspeccion de paquetes, VPN L2TP, IPSec con encriptacion, soporte de autenticacion RADIUS, proteccion contra DoS, listas de control de accesos, NAT, NAT transversal
However, vendors have combined PPTP with a similar protocol, Cisco Systems' Layer 2 Forwarding Protocol, to create L2TP, which they hope to present to the IETF for consideration as a standard.
Cada ruteador incluye un servidor integrado VPN, un cliente VPN para soportar multiples conexiones usando protocolos como IPSec, PPTP y L2TP; ademas, un puerto WAN 10/100Mbps para ser usado con conexiones de Internet de alta velocidad y un puerto COM, para el uso con una conexion telefonica externa por medio de un modem ISDN.
The Internet Engineering Task Force has approved a method called L2TP, which combines Microsoft's Point to Point Tunneling Protocol with Cisco's Layer 2 Forwarding tunneling scheme.
