A plurality of computing devices are provisioned configured to communicate on a mobile communications network operated, in part, by an edge computing network. The edge computing network is associated with a customer of a computing service provider. The edge computing network comprises computing and storage devices configured to extend computing resources of the computing service provider to the customer of the computing service provider. A selection is received of a SIM provider and a quantity of SIM profiles for enabling the plurality of computing devices to access the mobile communications network. SIM data corresponding to the quantity of SIM profiles is received. The SIM data is encrypted and received over an encrypted channel.

Encrypted flow of SIM data between regions and edge networks

In operation, packets traverse the packet processing data structure, and the network processing represented by each object in the data structure is applied to each packet. From time to time, the packet processing data structure may need to be updated. Embodiments of the present disclosure provide for lock-free updating of a packet processing data structure by means of epoch-based garbage collection. In embodiments, a particular past packet processing epoch is considered to be no longer referenced by any cores when the sequence numbers recorded in each said memory location are different to the sequence number of that particular past packet processing epoch. The deletion thread checks both whether a past epoch is being referenced by any packets and whether it is being reference by any cores. Thus memory is safely freed without having any impact on any packet processing which may be occurring in parallel to the deletion thread.
