Abstract: A method and system for email sender verification. A tag is included in an email that contains an identity datum for the sender that is associated with their email address in a server. The email is sent via a network, thus associating a sender address with the email. At least the identity datum, taken from the tag, is then provided to the server, to retrieve the email address. The email address and the sender address are then compared, verifying that the email came from the sender if these match.

Abstract: A dynamic private network (DNP)(100) for use in a tele or other communications infrastructure (102) to communicate between customer premises equipment CPE (30) via a network matrix (26). A DPN router (104) connects logical networks (106) having the CPE (30) to a datapath node (152).

Abstract: A bandwidth transfer switching system constructed of access concentrators, remote concentrators, relay nodes and at least one transfer switch. The access concentrators accept signals from various customer communications devices using switched signals and packet signals, including local area networks. The remote concentrators are optional, to group signals from multiple access concentrators. The relay nodes are also optional, to provided to increase signal distance. The transfer switch or switches receive the signals and route them onward to other customer devices located elsewhere. The transfer switches are located in a telco central office, or may be part of a private network constructed of access concentrators, remote concentrators, relay nodes and at least one transfer switch, or may be in a combination wherein a private network connects to a telco local loop.
