Generic Network Location Service provides a Location Service system based on DHT technology, which is storing device location records in nodes within a Chord DHT. Location records are consisting of network device identification keys as attributes, which are used to create replicas of additional location records through established hashing mechanisms. Specifically, we first discuss the design of an alternative approach to address translations based on DHT usage then report how fault-tolerance can be ensured through replication strategies namely proactive and reactive. As a result, we show how the record is stored in more copies and each copy provides access to others, allowing us to create efficient update and recovery mechanisms. Storing collections of network device identifications has some advantages: straightforward implementation of all possible translations at the same time (provides efficient discovery mechanisms for location services which are unavailable in current systems), and fault-tolerance to DHT's node and network failures due to inherent replication of identification records.

This work presents the Generic Network Location Service based on the Chord implementation utilizing data structures called distributed hash tables (DHT) or structured overlay networks, which are used to build scalable self-managing distributed systems. The provided algorithms guarantee resilience in the presence of dynamism: they guarantee consistent lookup results in the presence of nodes failing and leaving. Generic Network Location Service provides a Location Service system based on DHT technology, which is storing device location records in nodes within a Chord DHT. Location records are consisting of network device identification keys as attributes, which are used to create replicas of additional location records through established Chord hashing mechanisms. Storing device location records, in places address-able (using the DHT lookup) by individual location record keys provides a simple way of implementing transla¬tion functions similar to well¬ known network services (e.g. ARP, DNS, ENUM). The generic network location ser¬vice presented in the paper is not supposed to be a substitu¬tion of the existing translation techniques (e.g. ARP, DNS, ENUM), but it is considered as an overlay service that uses data available in existing systems and provides some translations currently unavailable.

Networking technologies use several addressing/ identification schemata (MAC addresses, IP addresses, DNS names, SIP URIs and E.164 numbers, GSM BTS identifications), efficient and reliable translations among them influence networking service. Older translation schemata are using tables and their hierarchies formed statically and dynamically (e.g. ARP, DNS, ENUM). Schemata for recent networking services (e.g. SIP which provides SIP URLs to IP addresses translation) are proposed on the basis of Distributed Hash Tables (DHTs).Our paper describes an alternative approach to address translations based on DHT usage. Identification record is formed of all identifications that the network device has, and all these identifications are used to create keys for storing the record to a DHT. As a result, the record is stored in more copies and each copy provides access to others, allowing us to create efficient update and recovery mechanisms. Storing collections of network identifications has some advantages: straightforward implementation of all possible translations at the same time (provides a way to location services which are unavailable in current systems), and fault-tolerance to DHT's node and network failures due to inherent replication of identification records.

Agile user requirements are typically givens as user stories written using natural language and they come in different forms. The most complex form of stories to work with are epics. If epics are poorly understood, they can contribute to threats regarding the sprints or projects becoming behind schedule. It can be attributed to the epic's complexity. The research aimed to explore and attempt the use of Stanza from the Stanford NLP group in the decomposition of epics by creating a text generative model. We have also utilised the chunking technique to formulate the tasks from the generated user stories by identifying the linguistic structure through the aid of a POS tagger. The obtained results illustrate that the stanza can be utilised in the requirements engineering domain such as Sprint backlog grooming. The benefits of this research work are enormous considering that sprint backlog grooming takes considerable time and is always in iterative mode. Agile teams will also benefit from this work by efficiently using sprint timeboxes with minimal sprint planning effort. This will enable agile teams to spend more time delivering the right solutions with reduced sprint planning time and effort.
