  • Patent number: 9893826
    Abstract: Network elements within a network are configured to retain clock traceability over an asynchronous interface. The network elements can generate and process multi-frames that include two different types of traffic, each synchronized to a different respective clock source. Each of the multi-frames is synchronized to the clock source of one of the traffic types and further includes a timestamp to enable the original clock signal of the other traffic type to be reconstructed at the receiving network element.
    Type: Grant

  • Patent number: 9774458
    Abstract: Network elements within a network are configured to transport Ethernet traffic and non-Ethernet traffic over a same medium. The network elements can generate and process multi-frames that include the Ethernet traffic and non-Ethernet traffic. Each of the plurality of group slots includes a first set of bytes allocated to carry the non-Ethernet traffic and a second set of bytes allocated to carry the Ethernet traffic. At least one group slot of the plurality of group slots includes a timestamp, and the network elements are further configured to use the timestamp to reconstruct the original spacing between packets of the Ethernet traffic.

  • Patent number: 9647782
    Abstract: We disclose an interface device configured to inter-convert CPRI data frames and Optical Transport Units (OTUs). The interface device acquires frame synchronization by temporarily storing data in a buffer bank such that translated sync characters are placed at respective predetermined locations within the buffer bank. Each translated sync character represents, in the corresponding OTU, a respective sync character of a CPRI hyperframe. The interface device is configured to distinguish translated sync characters from payload-data words of identical value based on predetermined alignment, in the buffer bank, of data temporarily stored therein for conversion into the CPRI data format. The interface device advantageously enables multiplexing of a plurality of CPRI links and aggregation and encapsulation of the multiplexed CPRI data into a stream of OTUs for transmission to the intended destination over an Optical Transport Network.

  • Patent number: 7653068
    Abstract: A method and apparatus for providing call admission control in a packet network such as an internet protocol (IP) network are provided. More particularly, a terminating endpoint of a logical connection on a packet network, e.g. an IP network, is provided with the ability to make a decision on whether to accept or reject an incoming call based on quality of service (QoS) indicator based on QoS metrics. These metrics indicate quality of service levels for specific logical connections and are accumulated over specified time periods.
