Edge-Based Evolved Packet Core (EPC) Refactoring for High Speed Mobility

NEC Virtualized Evolved Packet Core – vEPC

Signalling Effort Evaluation of Mobility Protocols within Evolved Packet Core Network

The Evolved Packet Core (EPC), IP based, as defined by 3GPP, is the core network for the 4th generation networks. Within the EPC there are two mobility protocols defined to use on the S5/S8 interface between the Serving Gateway (SGW) and the Packet Data Network Gateway (PGW). The architecture and functionalities of the two involved gateways are different either of GPRS Tunnelling Protocol (GTP)...

Hash-Based Techniques for High-Speed Packet Processing

Hashing is an extremely useful technique for a variety of high-speed packet-processing applications in routers. In this chapter, we survey much of the recent work in this area, paying particular attention to the interaction between theoretical and applied research. We assume very little background in either the theory or applications of hashing, reviewing the fundamentals as necessary.

Network Path and Quality Validation in the Evolved Packet Core

The Internet nowadays plays an imperative role in critical domains such as finance, health, security, entertainment and military where real-time services with guaranteed resources become necessary. Services residing within the application layer in today’s fixed and mobile network environments are abstracting from the underlying network layer, and therefore, assuming pure IP connectivity without...

Proactive Vertical Handover Optimizations in the 3GPP Evolved Packet Core

Mobility in a wireless heterogeneous scenario in which the mobile devices are able to connect to more than one access technology available in their vicinity requires a re-consideration of the access network reselection mechanisms as to ensure seamless handovers for real deployments. This paper describes and evaluates a new proactive vertical handover optimization which enables a fast reselectio...
