An apparatus and method for managing and characterizing clock domains in multi-domain networks are disclosed. A process of clock domain management is capable of receiving a data packet or data stream traveling across CES circuit. Upon obtaining a clock domain hierarchy stored in a storage location, the process identifies a clock frequency in the clock domain hierarchy in accordance with the CES circuit. The clock domain hierarchy, in one embodiment, is a searchable database containing information relating to clock domains. The clock frequency is subsequently assigned to a packet processing unit for data processing.

Methods and apparatus for characterizing adaptive clocking domains in multi-domain networks

An apparatus and method for managing clock domain(s) crossing several communication networks are disclosed. In one embodiment, a process capable of managing clock domains receives a data stream over a circuit emulation service ('CES'). Upon storing the data stream in a traffic buffer, the process selects a first clock domain for processing the data stream in the traffic buffer. For example, the process is capable of using the first clock domain to process and/or empty a jitter buffer, which stores CES data packets. The traffic buffer is monitored and the first clock domain can be replaced with a second clock domain if the storage capacity of the traffic buffer indicates that a different clock domain is needed.
