Various exemplary embodiments are a method and related system and computer-readable medium including one or more the following: receiving a data packet; analyzing the data packet using deep packet inspection (DPI) to determine an application associated with the data packet; determining an MPLS tunnel corresponding to the application associated with the data packet; and forwarding the data packet through the MPLS tunnel. In various exemplary embodiments, the step of analyzing the data packet including examining information in layers 2 through 7 of the data packet or analyzing the data packet to match an application signature. Furthermore, in various exemplary embodiments, the method and related system and computer-readable medium also includes adding a marking to the data packet to indicate the application associated with the data packet.

Application-aware MPLS tunnel selection

A network element has one or more logical communication interfaces each of which has a data set defining parameters for the interface. A data storage medium stores a profile containing information for an interface, the profile having a profile identifier for identifying the profile. The data set associated with an interface includes a profile identifier for enabling the communication interface to access information in the profile by referring to the profile identifier. The profile may include information relating to neighbor discovery communications between one network element and another, and the same profile may be accessed by any number of interfaces.

Communication system and method of configuring a communication interface

Various exemplary embodiments relate to a system and related method for transmission of content over a telecommunications network. The system may include a deep packet inspection (DPI) device configured to perform DPI to identify an application associated with the new flow, determine an amount of bandwidth required for the application, and determine a current amount of bandwidth used by the subscriber. The DPI device may then determine a total amount of bandwidth used by the subscriber. When the total amount of bandwidth exceeds an amount of bandwidth guaranteed to the subscriber, the DPI device may perform a traffic management action on packets belonging to the new flow, such that the total amount of bandwidth used by the subscriber does not exceed the amount of bandwidth guaranteed to the subscriber.

Application-specific management of high-bandwidth transfers

A system and method for interface association between an ATM interface and a GigE/IP interface of a routing switch platform (RSP) to enable network management of a redundant pair of RSPs which serve as an interface between GigE/IP and ATM are provided.

System and method of interface association for interface operational status event monitoring

A method and apparatus for emulating VPLS within an ATM network. Provider Edge devices are configured for VPLS connections. For each pair of provider edge devices supporting the same VPLS ID, one device establishes a virtual circuit between the pair. Thus, a full mesh of virtual circuits is established between provider edge devices, and a VPLS-like service can be offered to users without having to implement MPLS. Establishing the virtual circuits within a PNNI hierarchy maybe facilitated by each provider edge device propagating through the hierarchy an information group containing an association between the ATM address of the device and a VPLS ID, so that each provider edge device learns all ATM addresses to be associated with each VPLS ID. The method of advertising ATM addresses can be applied to other services requiring a number of interconnections between provider edge devices, such as Virtual Private Networks.

Providing VPLS-like service over native ATM networks

A system and method of translating a set of transmission parameters related to a first transmission protocol from said first transmission protocol to a second transmission protocol for a data element being sent on a connection from a first communication network utilizing the first transmission protocol to a second communication network utilizing the second transmission protocol is provided. The method includes mapping a first parameter from the set of transmission parameters to a class of service value for the connection and mapping the class of service value and a second parameter from the set of transmission parameters to another parameter for the second transmission protocol.

System and method for mapping quality of service levels between MPLS and ATM connections in a network element

A method and apparatus for sending packets from traffic flows to queues in a network element is provided. Each traffic flow has a packet size parameter indicating a sizing constraint for its packets. The method includes the step of grouping the traffic flows into groups utilizing the packet size parameter of each traffic flow. The method further includes the step of sending packets only from traffic flows of one group to at least one designated queue. Traffic flows of the one group are identified utilizing the packet size parameter of each traffic flow.

System and method for reassembling packets in a network element

A method for recognizing tones in a signal in a telecommunication transmission uses samples of the signal to determine whether a tone of an expected frequency and wave shape is contained in the signal. If the method accurately predicts the value of the next sample, then a tone of the expected frequency and wave shape has been detected. Another method may be used to recognize sequences of tones comprising intervals with particular frequencies and durations. The method may be applied to the detection of initiation sequences for fax and modem transmissions, for example the ITU-T recommendation T.30 V.21 fax initiation sequence and the ITU-T recommendation V.25 modem transmission preamble. The method may be incorporated in a device for detecting modem or fax transmissions on a line and routing such modem and fax transmissions to a modem/fax relay. Thus the invention can be used with devices which provide voice compression by ensuring that fax and modem transmissions are not corrupted by being passed through the voice compressors.
