A system and method for conducting a voice communication through a hybrid network which includes a packet internetwork, such as the Internet, connected to a circuit switched telephone network. The packet internetwork is connected to the switched telephone network through a static filter device, a packet switch, and a telephone network controlled gateway. A control processor is connected to the packet switch and to the filter device. The filter device generates a real time copy of call set up signaling dialog between the party requesting connection and the gateway which passes through or to the filter device. This duplicate of set up signaling is delivered from the filter device through the packet switch to the control processor. The control processor generates therefrom a filter device control signal which specifies the filter parameters derived from the set-up signaling dialog. This filter device control signal is delivered to the filter device and reconfigures the filter device to set filter parameters which are customized to the specific communication.

Offering vertical services to subscribers and service providers is an avenue to immediately improve the competitiveness of digital subscriber line access service, for example of the type offered by a local exchange carrier. To deliver high-quality vertical services, however, the underlying ADSL Data Network (ADN) or the like needs to establish Quality of Service (QoS) as a core characteristic and offer an efficient mechanism for insertion of the vertical services. The inventive network architecture introduces QoS into the ADN, in a manner that enables the delivery of sophisticated and demanding IP-based services to subscribers, does not affect existing Internet tiers of service, and is cost-effective in terms of initial costs, build-out, and ongoing operations. The architecture utilizes a switch capable of examining and selectively forwarding packets or frames based on higher layer information in the protocol stack, that is to say on information that is encapsulated in the layer- information utilized to define normal connectivity through the network. The switch enables segregation of upstream traffic by type and downstream aggregation of Internet traffic together with traffic from a local vertical services domain.

There is provided a protocol separator having a processor with an input port and output ports, and data links connected to the input port and to the output ports, with the data link to the input port carrying packetized data including packets of different protocols, the data link to one of the output ports carrying packets of a first protocol removed from the stream by the processor, and with the data link connected to the other output port carrying the remainder of the packets which were delivered to the input port. The protocol separator operates by determining at least part of a byte in the selected protocol packets which characterizes that protocol, monitoring the stream to detect the occurrence of that part of a byte, and diverting packets containing the part of a byte from the stream to one of the outputs. The remainder of the stream is fed to the second output.

Aggregating physical connections from customers for presentation to an access router and de-aggregating traffic from a shared link(s) from the access router. Ports of an aggregation unit may be configured such that each has a unique identifier in the place of information (e. g. , the layer address) originally in the layer header. The layer (e. g. , MAC) address of the customer device connected with the port can be associated with, and therefore determined from, the IP address of the attached device. When a packet is received from a customer, information in the layer header is changed to a unique identifier assigned to a logical port or interface associated with the physical port. When a packet is received from the access router, it is placed on the port assigned to the logical port associated with the destination layer address (or associated with other bits of the unique bit string and at least some of those bits are replaced with the destination layer address of the device associated with the port.

The switch enables segregation of upstream traffic by type and downstream aggregation of Internet traffic together with traffic from a local vertical services domain.

Limiting or controlling access to various services thereby performing a firewall function. An access router may permit or deny a packet based on at least a portion of a unique bit string (or context information) which replaced layer header information (e. g. , the layer (e. g. , MAC) address). Further, a particular quality of service may be indicated by at least a part of the unique bit string (or context information). The service provided to a group of customers, that group of customers being defined by at least a portion of the unique bit string (or context information), may be monitored. Multicast groups may be supported by checking at least a part of the unique bit string (or context information) to determine whether or not a customer associated with that port is permitted to join the multicast group.
