Communication traffic isolation and control systems and methods are disclosed. Communication traffic streams are received and either passed or filtered by respective controllable filtering modules. The operation of the filtering modules is controlled on a per-module and thus a per-stream basis, responsive to congestion of filtered communication traffic streams at a communication traffic processing element to which the filtering modules are connected. Per-stream filtering provides traffic control for each communication traffic stream, and maintains isolation between the streams. Statistics associated with communication traffic filtered out of each stream may be collected, and possibly aggregated.

A method of detecting missing fragments and idle links in a link bundle for a multilink protocol, and devices provisioned with program instructions for performing the method, employs a plurality of masks to track the links in the bundle that are active. Idle links are excluded from a determination about whether buffer cleanup should be run in order to reduce unnecessary buffer usage caused by orphaned fragments.

A method of collecting consistent flow statistics through multiple congestion points within a multi-service switch/router is enabled by computing a payload length of each traffic unit received from a fabric of the switch/router. A PHY-level header containing the payload length, a class of service and a service ID is appended to the switch-internal encapsulated payload. Information associated with the PHY-level header is used at physical level congestion points to collect consistent flow statistics.

Electronic device configuration management systems and methods are disclosed. Configuration information for configuring at least one component of an electronic device is stored in a memory. A determination is made as to whether further configuration information capable of configuring the at least one component is available at the electronic device. Based on the determination, one of the configuration information and the further configuration information is loaded to configure the at least one component. The determination may be made, for example, by accessing compatibility information which is associated with the configuration information. Data structures supporting configuration management functions are also disclosed.
