Hi Group,
SR compression design team have submitted a new version of compression
requirement draft.
Main changes as follows:
- added 3 items about scalibility with agreement within the design team
- added an appendix including 3 items without without unanimous
consensus within the design team
Hi all,
the the appendix A of latest draft version includes three items that
should be taken into consideration, in particular:
Requirement A.2.1. SRv6 Based
Requirement A.2.2. SRv6 Functionality
"A solution to compress SRv6 SID Lists SHOULD be based on the SRv6
architecture, control plane and data plane" and "A solution to compress
an SRv6 SID list MUST support the functionality of SRv6"
I've been working in the last 4 years on the open source ecosystem
supporting SRv6, including the support of SRv6 in the Linux kernel
(see https://netgroup.github.io/rose/)
a lot of effort has been spent in this ecosystem that now offers a
feature set comparable to vendors' implementation of SRv6
it is very important for the research community to have such ecosystem
and it will be painful to rebuild the support for a new solution outside
of the current SRv6 architecture... one of the problem of the MPLS
architecture (from the research comunity point of wiew) was that the
support in Linux has never been comparable to vendors's solution (e.g.
for the control plane), for this reason the research work diverged a lot
from production solutions, I really would like to avoid such gap again
Requirement A.2.3. Heterogeneous SID lists
"The compression proposal SHOULD support a combination of compressed and
non-compressed segments in a single path."
We have been working a lot on Service Function Chaining supported by
SRv6, and we have use cases that require non-compressed segments to
include arbitrary functions in the chain and provide them the needed
information. It is very important to have the possibility to combine SFC
with other features (e.g. traffic engineered paths) requiring compressed
segments in a single "end-to-end" perspective. This would support
end-to-end scenarios combining for example IoT at the edge, 5G access,
metro/wan interconnection, SFC in the metro/wan, SFC in datacenter. This
is only possible if compressed and non-compressed segments are combined.
ciao
Stefano
- some minor text issue fixed
Please review it and let us know your comments.
BTW: We will have 1-hour session for the design team topic on Friday and
welcome to join us.

Weiqiang on behalf of design team
