A system for protocol processing in a computer network has an intelligent network interface card (INIC) or communication processing device (CPD) associated with a host computer. The INIC provides a fast-path that avoids protocol processing for most large multipacket messages, greatly accelerating data communication. The INIC also assists the host for those message packets that are chosen for processing by host software layers. A communication control block for a message is defined that allows DMA controllers of the INIC to move data, free of headers, directly to or from a destination or source in the host. The context is stored in the INIC as a communication control block (CCB) that can be passed back to the host for message processing by the host. The INIC contains specialized hardware circuits that are much faster at their specific tasks than a general purpose CPU. A preferred embodiment includes a trio of pipelined processors with separate processors devoted to transmit, receive and management processing, with full duplex communication for four fast Ethernet nodes.

Methods and systems for routing call signaling messages are disclosed. One such method is performed in a session router. The method includes: maintaining a telephony route information base (TRIB) stored in the session router as a result of participation of the session router in telephony routing over internet protocol (TRIP). The TRIB allows multiple routes to the same destination. The method further comprises: using the TRIB to route the received call signaling messages to another session router. One such system includes memory and a processor. The processor is configured by instructions retrieved from the memory to: build and maintain, as a result of participation of the router in telephony routing over internet protocol (TRIP), a telephony route information base (TRIB) that allows multiple routes to the same destination; and use the TRIB to route a received call signaling message to another router.
摘要:
A network for coupling at least one telephone service signal to at least one telephone device over a wiring. The network includes: a wiring having at least two conductors for carrying multiple time-domain multiplexed digitized voice channels; an exchange side device coupled to the wiring and operative to couple at least one telephone service signal to at least one digitized voice channel; and at least one subscriber side device coupled to the wiring and operative to couple the at least one telephone device to at least one digitized voice channel.

A communications network is disclosed and includes a broadband communication line having a first derived voice channel and a second derived voice channel, wherein the first and second derived voice channels are established as a function of an available bandwidth associated with the broadband communication line. The communication network further includes a residential gateway in communication with the broadband communication line. The residential gateway includes a switch, a network interface device in communication with the switch, and wherein the switch is configured to select at least one of the first or second derived voice channels for voice communication over the broadband communication line as a function of the available bandwidth.

摘要:
A new architecture capable of utilizing the existing twisted pair interface between customer premises equipment and an associated serving local switching office is used to provide a vast array of new services to customers. Using an intelligent services director (ISD) at the customer services equipment as an interface for the equipment to an existing twisted cable pair and a facilities management platform (FMP) at the serving local switching office as an interface to various networks and service opportunities, new services such as simultaneous, multiple calls (voice analog or digital), facsimile, Internet traffic and other data can be transmitted and received over the twisted cable pair by using digital subscriber loop transmission schemes. The new services include but are not limited to videophone, utility meter reading and monitoring, broadcasting and multicasting. The architecture provides for fault-tolerant, transparent interaction of components and services and supports a variety of standards for each level of the open systems interconnection layers and layers of TCP/IP. The FMP connects electronically or optically to the public switched telephone network, Internet backbone, a private Intranet as well as other possible network connections.
摘要:
An integrated access system and method and an integrated access module are provided. The system includes a broadband service interface module (310), a narrowband service interface module (320), and a main control switching interface module (10). The main control switching module (10) includes a broadband service switching module (110) providing a broadband uplink interface and a narrowband service processing module (120) providing a narrowband uplink interface and performing narrowband service data process. The broadband service switching module (110) is connected to the broadband service interface module (310) and the narrowband service interface module (320) though broadband buses (21), so as to collect and switch the narrowband service data. The broad band service switching module (110) is connected with network though the broadband uplink interface, and the narrowband service processing module (120) is connected with network though the narrowband uplink interface. Thus, the broadband service and the narrowband service can be accessed simultaneously.
