Telecom strategies for service discovery in microservice environments

In order to communicate with another service, a service needs to know the address of other services. This knowledge can be acquired by a process called service discovery (SD). In a microservice architecture (MSA), unlike SOA, a service discovery framework has not been provided out of the box. In a telecom environment additional requirements may arise, besides the basic one of discoverability. In this paper we shortly present the state of the art in service discovery with reflections on the specific needs of MSA and in particular in the context of telecom applications. In this context open source frameworks are investigated and compared.

Multidimensional Resource Allocation in NFV Cloud

  • Goldstein M.
  • Raz D.
  • Segall I.

Network Function Virtualization (NFV) is a new networking paradigm in which network functionality is implemented on top of virtual infrastructure deployed over COTS servers. One of the main motivations for the shift of telco operators into this paradigm is cost reduction, thus the efficient use of resources is an important ...

Network Function Virtualization (NFV) is a novel paradigm allowing flexible and scalable implementation of network services on cloud infrastructure. An important enabler for the NFV paradigm is software switching, which needs to satisfy rigid network requirements such as high throughput and low latency. Despite recent research activities in the field ...

Coexistence-aware dynamic channel allocation for 3.5 GHz shared spectrum systems

The paradigm of shared spectrum allows secondary devices to opportunistically access spectrum bands underutilized by primary owners. As the first step, the FCC targeted sharing the 3.5 GHz (3550–3700 MHz) federal spectrum with commercial systems. The proposed rules require a Spectrum Access System to implement a three-tiered spectrum management framework, ...
