Efficient Multipath Service Function Chaining in Inter-Data Center Networks
Mārtiņš Mihaeljans, Andris Skrastiņš · 2023
This paper is complimentary research to our previous paper [1] on Service Function Chaining (SFC) symmetries effect on network function (NF) such as firewall (FW) application successfulness. This studies focus is on service function (SF) usability improvements in inter-data center networks. We introduce a method of network traffic simultaneous steering through multiple SFs in SFC domain stretching over two data centers (DCs), resulting in resource sharing among both DCs. We tested such methods efficiency via conducting a series of simulations in GNS3. Results indicate an overall increase in successful available bandwidth utilization (from 0.3 to 0.65) measuring AVG throughput.
