A connectivity manager (CM) of a provider network establishes a plurality of ERGs (edge resource groups), each comprising at least an edge router and a network marker translation agent (NMTA). The CM selects a particular ERG to be used for network traffic between a first set of resources of a virtual computing service of the provider network and a second set of resources outside the provider network. To enable connectivity between the first and second set of resources, the CM initiate propagation of (a) routing metadata to an edge router of the particular ERG and/or (b) a network marker mapping entry to an NMTA of the particular ERG.

Grouping routing resources for isolated virtual network traffic management

The invention relates to a method for monitoring a detachable fiber-optic connection, especially in a fiber-optic transmission device or system, comprising the steps of transmitting a wanted optical transmission signal carrying information data to be transmitted to at least one fiber-optic connection, a predetermined portion of the power of said optical transmission signal being reflected at the at least one fiber-optic connection depending on the status and properties of the at least one fiber-optic connection, creating a detection signal by detecting said reflected predetermined portion of the power of said optical transmission signal, monitoring and evaluating the detection signal as a function of time and creating a 'DETECT' signal if the detection signal or a signal derived from the detection signal reveals a characteristic change in its course in time. Further, the invention relates to a corresponding device adapted to realize this method.

A method for proving the validity of a digital document digitally signed using a digital key that corresponds to a digital certificate in a chain of digital certificates issued by certification authorities within a hierarchy of certification authorities. At least one secure digital time stamp is applied to at least one record comprising the digital document, the digital signature, certificate chain data, and information relating to the revocation of certificates by certification authorities within the certificate chain. If, at some later time, one or more digital certificates either expire or are revoked, the timestamp serves as evidence of the integrity of the signed digital document.
