20090103448 | APPARATUS, METHOD AND COMPUTER-READABLE STORAGE MEDIUM FOR CALCULATING THROUGHPUT REQUIREMENTS OF A NETWORK - An apparatus, method and computer-readable storage medium are provided for calculating an estimated throughput requirement of a network, such as to facilitate selecting the minimum bandwidth, maximum bandwidth or some other appropriate bandwidth for providing network services to a customer accessing that network. In this regard, a method of calculating a throughput requirement of a network includes receiving a bandwidth requirement. The method also includes calculating a data link-layer frame rate requirement based on the bandwidth requirement and a frame size, where the calculated frame rate requirement is limited by a line rate for transmission of data packets across a core network. In addition, the method includes calculating a data link-layer throughput requirement based on the calculated frame rate requirement and the frame size. | 04-23-2009 |
20090129289 | SYSTEM, METHOD AND COMPUTER-READABLE STORAGE MEDIUM FOR CALCULATING ADDRESSING AND BANDWIDTH REQUIREMENTS OF A NETWORK - Apparatuses, methods and computer-readable storage mediums are provided for calculating estimated addressing and bandwidth requirements of a customer domain, such as to facilitate designing the respective domain. A method includes selecting customer premises equipment (CPE) of a domain including a plurality of CPEs, where each CPE includes one or more devices, and one of the one or more devices include an interface with which the domain communicates with the respective CPE. The method also includes determining if the interface of the selected CPE comprises a router, and calculating an addressing requirement of the selected CPE, where the addressing requirement includes a number of device addresses for the selected CPE. The method may additionally or alternatively include analyzing traffic patterns of the selected CPE with respect to one or more other CPEs, and based on the analysis, calculating a bandwidth requirement of the selected CPE. | 05-21-2009 |

20140056126 | METHOD AND SYSTEM FOR PROVIDING FAULT ISOLATION FOR A SERVICE PATH IN AN ETHERNET-BASED NETWORK - An approach for providing fault isolation for a service path in an Ethernet-based network is described. A service path within an Ethernet-based network and associated with a plurality of management levels is determined. A plurality of management points that are along the service path and that correspond to the management levels are monitored. An occurrence of a fault at one of the management points associated with the service path is identified based on the monitoring. | 02-27-2014 |
20140068106 | METHOD AND SYSTEM FOR PROVIDING LATENCY DETECTION BASED ON AUTOMATED LATENCY MEASUREMENTS OF COMMUNICATION NETWORK PATHS - An approach for providing latency measurements for a communication path of a transmission network is described. Measurement of latency associated with one or more communication paths of a transmission network is initiated. An increase in the latency within the transmission network is detected based on the latency measurement. One or more secondary communication paths of the transmission network are determined to address the latency increase. One of the secondary communication paths is selected according to a latency threshold. | 03-06-2014 |

20100040206 | SYSTEM AND METHOD FOR CONTROLLING COMMUNICATION FLOW RATES - A system and method are provided for providing access communications between customer locations and a core network service edge. Access flows are handled as carrier-tagged flows through a packet switched network comprising network elements that interpret and manipulate carrier tag values associated with traffic-bearing data frames. In accordance with a preferred embodiment, a discard eligibility indication may be provided with the data frames. | 02-18-2010 |
20100182914 | APPARATUS AND METHOD FOR TESTING AND FAULT ISOLATION IN A COMMUNICATION NETWORK - An apparatus and method for performing automated testing and trouble isolation of a communications link in an access network is described. Communications link testing may occur without taking the communications link out of service for the duration of the test. | 07-22-2010 |
20110075560 | METHOD AND APPARATUS FOR PROCESSING LABELED FLOWS IN A COMMUNICATIONS ACCESS NETWORK - A system and method is provided for managing access communications between the service edge of a communications service provider and a customer. Access communications are carried in the form of carrier-tagged flows, the communications traffic being appended with carrier tags having significance to handling of the traffic through access network elements. A building aggregation system is provided which couples to customer premise equipment and interfaces customer flows to carrier-tagged flows used in the access network. | 03-31-2011 |
20120307830 | SYSTEM AND METHOD FOR A COMMUNICATIONS ACCESS NETWORK - A system and method are provided for providing access communications between customer locations and a core network service edge. Access flows are handled as carrier-tagged flows through a packet switched network comprising network elements that interpret and manipulate carrier tag values associated with traffic-bearing data frames. | 12-06-2012 |
20130272161 | SYSTEM AND METHOD FOR INDICATING CLASSIFICATION OF A COMMUNICATIONS FLOW - System and method for providing a layer 2 switch in the access network that switches based upon one or more carrier tags identifying customer traffic. Customer traffic conforming to any variety of different layer 1 or layer 2 protocols may be encapsulated and identified according to carrier tag values. The layer 2 switch may determine how to handle the traffic by interpreting and manipulating the carrier tag values. The layer 2 switch may be capable of switching TDM input traffic to either TDM or packet output traffic, and switching packetized input traffic to either TDM or packet output traffic. Handling classification values may also be processed by the layer 2 switch to affect prioritization of handling of encapsulated traffic. | 10-17-2013 |
