Verizon offers both clientless and client-server Web optimization services, which it says can improve effective performance by two to three times the raw throughput rate. If you combine that with Verizon's EV-DO network, which offers average throughput of 300 Kbps to 500 Kbps, Verizon can lay legitimate claim to best broadband performance, at least in the limited markets where EV-DO is available. Only Nextel's Flash OFDM trial network in North Carolina is faster.
Verizon offers multiple wireless e-mail and messaging services. Its VZEmail system, which is based on technology from Intellisync, is targeted for Microsoft and PalmOS smartphone platforms and provides wireless e-mail and PIM sync between mobile devices and desktop computers. RIM BlackBerry also is supported.
Verizon supports both direct integration with enterprise networks using frame relay and T1, and a network-to-network VPN option. All IP addresses on Verizon's system are public, and the company supports both public and private options. Verizon does not support private addresses, and the company did not provide any information about reserved address blocks or mapping of enterprise IP addresses into its system. Unfortunately, the company did not honor our request for a follow-up interview, nor did it respond to a follow-up e-mail inquiry.
