With the advances in cloud computing, the telecom operators are moving towards virtualization and cloud model. The future mobile networks are going to be deployed in the cloud with the help of Software Defined Networks (SDN) and Network Functions Virtualization (NFV) technologies. This thesis discusses various aspects related to prototyping and orchestration of slicing in LTE and 5G core networks using open-source technologies. The network slices are created in the user plane of the core network for differentiating the user traffic in terms of their QoS requirements. The Service Based Architecture (SBA) of 5G core is realized with the help of Google Remote Procedure Call (gRPC) as Service Based Interface (SBI) and Consul as Network Function Repository Function. On top of the setup created, the concept of Look-aside Load Balancing is used, to suit the 5G SBA and efficiently handle the incoming traffic load. With the Access and Mobility Management Function as a use case for load balancing, it is concluded that carefully chosen load balancing algorithms can significantly lessen the control plane latency when compared to simple random or round-robin schemes.
