Embodiment Construction

[0026] Currently, telecommunication applications such as Gateway GPRS Support Node (GGSN), Serving Gateway (SGW), Packet Data Network Gateway (PGW), Trusted WLAN Access Gateway / Trusted WLAN Access Agent ( TWAG / TWAP) and Evolved Packet Data Gateway (ePDG)). These mechanisms generally result in important dynamic information concerning the current state of a specific protocol defined during its subscriber or data stream processing by 3GPP, IETF, ETSI or other bodies, which is stored in at least two locations within the distributed system , such as 2 processes on 2 compute instances (eg, virtual machines (VMs), 2 containers, or on 2 bare metal servers). As used herein, embodiments describing virtual machines are equally applicable to containers and bare metal servers. Such dynamic states include call states such as (such as mobile location) and billing states (eg usage counters). Dynamic states can change extremely quickly. For example, the billing status may be updated on ever...

Abstract

A method includes receiving network element data from a first computing instance hosting a network element instance. The network element data includes identification and status information associated with the network element instance. The method includes creating a key based on network element data including a network element identifier and a classified table identifier of state information. A network element identifier is associated with identifying information. The method includes storing keys and state information in a database and determining a failure of the first computing instance. The method includes determining a key associated with the network element identifier of the network element instance and sending activation data to the second computing instance. The activation data is associated with instructions for retrieving a record including state information associated with a key, the key being associated with the first network identifier, to recreate the first network element instance.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Provisional Application No. 62 / 279,240, entitled "Database Based Redundancy in a Telecommunications Network," filed January 15, 2016, which is incorporated by reference Incorporated into this article. technical field [0003] This disclosure relates to the field of telecommunications, and more particularly to techniques for using databases for redundancy in telecommunications networks. Background technique [0004] In a conventional approach for achieving very highly available and redundant telecommunication applications, to allow state synchronization from primary to secondary computing instances, the number of computing elements (e.g., virtual machines (VMs) or hosts) is at least N+1 and sometimes 2N. The total memory required is 2N, since every important state has to be replicated in memory at the second location. To complete this scenario, code must be written and tested ...
