Abstract: A distributed subscriber management system and method that controls access to a network preventing unauthorized traffic through the access network and providing centralized access control between user networks are disclosed. The controlled access is provided through the use of one of several technologies including user authentication, using PAP, CHAP, RADIUS, TACACS+. The method includes the steps of receiving a connection request from a user located on one of the User Networks; interrogating the user for userid and password information; encrypting the userid and password information; transmitting the encrypted information, via the access network, to an authentication server attached to one of a plurality of external networks; decrypting the information at the authentication server; and transmitting an authentication message from the authentication server of the external network to the access control node via the access network.

Abstract: A method of transmitting interleaved real-time and non-real-time data on a packet based network so as to provide voice Quality of Service comparable to the Time Division Multiplexing realm of traditional telephony. The method reduces packet jitter and delay by employing separate queues for the different types of data as well as through the use of jitter buffers. The interleaving method consists of a number of discrete concepts and mechanisms that when used together in the manner disclosed herein provides consistent high-quality transmission of real-time data over packet/frame/cell-based networks. The elements required for this method include time-slot co-ordination, a dynamic MTU algorithm, and a Multiple queue egress traffic management system.

Abstract: A method and device are provided for an improved system and method of labeling data units with a domain field that is fast, scalable and simple to implement in domain switching applications without adding to the protocol overhead. The system and method are also suitable for point-to-multipoint configurations.
