A network device on a managed network is identified, wherein the network device is identified as a one of a list of one or more network device types supported by the managed network and included in one or more configuration files, and wherein the one or more configuration files further include a list of one or more respective SNMP variables to be monitored for each of the network device types. The respective listing of SNMP variables to be monitored and/or configured is extracted from the one or more configuration files for the identified network device type.

Abstract: An apparatus, method, and system for quality of service over dedicated local loop networks is provided. Information regarding uplink and downlink speeds, and information regarding WAN interface protocol and encapsulation mode, is received from a network device. A link throughput limit is calculated based on the uplink speed of the network device, and a link throughput limit is set based on the calculated uplink throughput limit. An uplink network protocol overhead of the network device is calculated based on the WAN interface protocol and encapsulation mode of the uplink device and is factored in upstream available bandwidth calculations. Communication data size(s) are set based on the calculated uplink network protocol overhead. The downlink throughput limit is set to match the downlink speed based on the downlink speed and WAN network protocol overhead. The WAN network protocol overhead is factored in the downstream available bandwidth calculations and communication data sizes.

Abstract: A receiver is used with third code blocks based on first code blocks, second code blocks, and a planning code block. The first code blocks are associated with a first sequence number and modulated with a first modulation scheme. The second code blocks are associated with a second sequence number and modulated with a second modulation scheme. The planning code block associates the third code blocks with the first code blocks and the second code blocks. The receiver includes a de-multiplexing portion, which includes a code block selector and a look up table, that outputs a de-multiplexed signal based on the third code blocks. The code block selector selects a code block from the third code blocks to output as the de-multiplexed signal based on entries in the look up table. The receiver also includes a recovery portion that outputs received code blocks based on the de-multiplexed signal.

Abstract: A parameterized interleaver design process is provided, which optimizes the design for interleavers of any size, and can be completely specified using only a few design parameters. According to the parameterized interleaver design process an interleaver ?(i) of a length N is generated. A number of subpermutation masks are defined, and a first intermediate interleaver permutation is partitioned into a number of subgroups, wherein the number of subgroups corresponds with the number of subpermutation masks. Each of the subgroups of the first intermediate interleaver permutation is partitioned into a number of further subgroups, and each of the subpermutation masks is applied to each of the further subgroups of a corresponding subgroup of the first intermediate interleaver permutation, resulting in a corresponding portion of a second intermediate interleaver permutation. The resulting interleaver ?(i) is generated based at least in part on the first and second intermediate interleaver permutations.

Abstract: A new pulse shape for CPM is introduced which is obtained by a linear combination of well-known RC and REC pulse shapes. The new pulse shape addresses the tradeoff between the width of the PSD main lobe and the rate of decay of the side lobe to improve the coded performance of multi-carrier systems affected by ACI. Also, a methodology is proposed to design and evaluate the performance of the new pulse shape for multi-carrier, coded systems based on the modulation constrained capacity. Furthermore, a binary convolutional code and the CPM modulator are concatenated using an S-random bit interleaver to lower the error floor. Finally, Laurent representation of the new pulse shape is suggested such that by retaining only the principal pulses at the receiver, complexity of the receiver can be reduced.

Abstract: An approach is provided for graceful shutdown and startup of spoofing when a handover procedure is performed. A handover of a performance enhancing proxy (PEP) session associated with a transport connection is detected. A shutdown procedure is initiated to stop spoofing of the transport connection in response to the detected handover. The shutdown procedure avoids teardown of the transport connection during the handover from a first link to a second link of a communication system.

Abstract: A communication system for retrieving content stored in a content server (e.g., web server) is disclosed. The system includes a client that is configured to transmit a message requesting content specifying an object from a content server. The system also includes a plurality of proxy servers that include a downstream proxy server and an upstream proxy server. The downstream proxy server is configured to communicate with the client. The upstream proxy server is configured to retrieve the content from the content server and to forward information associated with the object over a data network to the downstream proxy server prior to the client transmitting another message requesting the object. The above arrangement has particular application to a wide area network, such as a satellite network.

Abstract: A new coded continuous phase modulation (CPM) scheme is proposed to enhance physical layer performance of the current DVB-RCS standard for a satellite communication system. The proposed CPM scheme uses a phase pulse design and combination of modulation parameters to shape the power spectrum of CPM signal in order to improve resilience to adjacent channel interference (ACI). Additionally, it improves error rate performance at both high and low frame error rates using low complexity binary convolutional codes and S-random bit interleaving. Phase response using the proposed CPM scheme is a weighted average of the conventional rectangular and raised-cosine responses and provides optimum response to minimize frame error rate for a given data rate.

Abstract: An approach is provided for shaping traffic of a communication system. Resource usage of a network element of the communication system is determined. The usage is compared with thresholds that are established according to loading of the communication system; these thresholds correspond to various transmission states that limit usage of the resources of the communication system (e.g., bandwidth). Further, based on the comparison, the resource usage of the network element is controlled according to a particular transmission state, thereby ensuring fair access. This approach as particular applicability to shared capacity systems, such as a satellite communication system.
