Re: [ovs-discuss] Query on DEC_ttl action implementation in datapath

I think it was considered cleaner from an ABI perspective, since it doesn't require another action, since "set" was already supported. In practice, I don't think it's a problem, since usually a TTL decrement is associated with a routing decision, and TTLs tend to be fairly static between two

Re: [ovs-discuss] OFPACT_DEC_TTL in kernel space

We try to implement the minimum interface that we can in the kernel. Usually the TTL doesn't change across a flow, so matching on a particular TTL value and setting a new value isn't a problem. Plus, it allows us flexibility to stack multiple OpenFlow decrements (useful for logical routers,

Re: [ovs-discuss] Throughput losses with HP Switch

I don't think this is the right forum for this question, since it doesn't seem related to OVS. However, if I were to speculate, my guess is that the forwarding ASIC doesn't support modifying the ToS bits, so the packets are being forwarded to the management CPU to handle these packets. You

Re: [ovs-discuss] MPLS issue in OVS

I know very little about the MPLS integration, but I have one thing that might be worth checking. Are you using the OVS kernel module that came with OVS 2.6.1 or the one that comes with Linux 4.2? Linux 4.2 came out a year before OVS 2.6, and 2.6 introduced MPLS TTL. It looks like the kernel

Re: [ovs-discuss] how does tos/dscp mechanism work on ovs?

OVS doesn't automatically do anything with those fields itself. If you want to do that, you can configure queues and then write flows that match on those fields and output to a particular queue. --Justin > On Mar 18, 2017, at 6:21 AM, Big Strong wrote: > > TOS/DSCP is
