A fiber optic cable includes a core and a binder film surrounding the core. The light shield comprises a structure formed above a point between a photo-sensitive element and adjacent circuitry. As an alternative, vertical movement may be effected via a second drive mechanism that may be actuated by the operator using a foot pedal. Such a context table may be dynamically reconfigured in order to group connections for buffer monitoring operations related to congestion detection, traffic shaping, and data admission with respect to buffering. Thus, public-keys of users, such as email recipients, can be searched and retrieved over the internet based on a unique identifier of the user, facilitating secure communication between users in different network domains and organizations.
