Title
A scalable header compression scheme to improve bandwidth utilization in 5G networks.
Abstract
The low efficiency of bandwidth utilization is a serious problem facing current 5G networks. Header compression and Software Defined Networking (SDN) are two key technologies that can greatly improve the efficiency of bandwidth utilization. With the usage of these technologies, current solutions perform packet routing on the basis of context identifier (CID) in 5G core networks. However, these solutions have a limited invariant capacity to compress data flows simultaneously. In addition, the invalidation in the aggregation of flow table entries leads to a serious routing scalability problem. To solve the capacity and routing scalability problems, we propose a novel end-to-end header compression scheme for 5G networks. The basic idea of our scheme is to set short tags in layer 2 or 2.5 protocol stack to stand for the location of compressors, forwarding devices route the packets based on these tags, allowing CIDs that have an identical value to coexist in the same network. In this paper, we describe the system model of our scheme and analyze its performance in comparison with current solutions. We also performed some evaluation experiments, and the results show that our scheme allows a huge amount of data flows to be compressed and improves the efficiency of bandwidth utilization effectively.
