    摘要： Processing of a signal received at a node in a network is described in which effects on the signal caused by applying an action to a first part of the signal are quantified based on characteristics of the first part of the signal and effects on the signal caused by not applying the action to the first part of the signal are quantified based on characteristics of a second, subsequent part of the signal. The action may then be selectively applied either to the first part of the signal or to the second part of the signal based upon the quantifications. In some embodiments, the action is applied to a portion of the signal for which the effects on at least one measure of the signal quality are less detrimental.

    摘要： Methods and systems are provided for hardware-accelerated packet multicasting in a virtual routing system. According to one embodiment, a multicast packet is received at an ingress system of a packet-forwarding engine (PFE). The ingress system identifies flow classification indices for the multicast packet. Then, for each instance of multicasting, the ingress system sends a single copy of the multicast packet and the flow classification indices to an egress system of the PFE. The single copy of the multicast packet is buffered in a memory accessible by the egress system. The egress system prepares the multicast packet for transmission by for each flow classification index, identifying corresponding transform control instructions based on the flow classification index, reading the single copy of the multicast packet from the memory, causing the multicast packet to be transformed in accordance with the identified transform control instructions and outputting the transformed multicast packet.

    摘要： Presently described is a system and method for switching multimedia data communications, including but not limited to Voice over IP (VoIP) telephony, cable TV, digital audio and video. The system utilizes a single, integrated device to provide all PacketCable-compliant functionality, including enhanced user privacy, compliance with CALEA, E911 and other mandated services not available in conventional distributed PacketCable systems. High speed and efficient, low cost operation are provided by means of an optimized data unit encapsulation scheme for internal switching and routing. A proprietary fiber optic backplane and removable optical connectors are used to enable lightspeed internal communications hot-swapping of components. Furthermore, the present system is extensible to all forms of digital data switching and is secure, resistant to Denial of Service attacks, and fault-resilient.
