Abstract:
In this document, we use SF classification of 1)indispensible SF for
packet delivery, allegedly mandatory SFs, such as NAT and 2)optional
SFs that a packet can be delivered without them, such as Firewall and
IDS.
The nodes of SFC-enabled domain can be various. Different vendors
make different types of equipments, and this causes performance
issues. Considering this diversity, the kind of SFs can be in myriad
form. Thus, we should distinguish some mandatory SFs from not
mandatory SFs and treat distinctively. Mandatory SFs should be
matched with higher-performance SFF to achieve high availability as
well as lower the probability of failure. Above all, whether each SF
is mandatory or optional should be registered in advance. Mandatory
SFs are to allocated to relatively higher-performance, larger
capacity, more stable SFFs. SFC constructed using this way of
allocation becomes the path for packets and packets are transferred
to classifier through C1 interface, and to SFF through C2 interface,
respectively.
