[vpp-dev] BondedInterface and memif interface for raw packet #memif #BondedInterface #plugin

[Edited Message Follows] Hi Experts, We implemented a PLUGIN, this plugin reads packets from physical interface and sends to memif. We implemented this approach to get RAW packets to our application. The memif other end is our application, it takes necessary action. The packet flow would be Devi

[vpp-dev] Buffer chains and pre-data area

Dear vpp-dev, I'm trying to do some IPv6 in IPv6 encapsulation with no tunnel configuration. The objective is to encapsulate the received packet in an other IPv6 packet that will also "contain" a Hop-by-hop extension header. In summary, the structure of the final packet will look like this :

Re: [vpp-dev] MPLS protection

Thanks Neale for responding. “HA LSP” – I was referring to primary LSP (Label Switching Path) and backup LSP. There can be two or more label encaps configured as a group for each label-level in the packet header. In that configuration group, one label will refer to primary next-hop and others w

[vpp-dev] HQOS in latest VPP

Hi, It looks like Hierarchical Queuing support is not supported in the latest VPP release. The last release I see is 20.01. Any plans to support it again in the future VPP? I don't see the config commands or nor hqos code in the latest VPP release. Thanks, Satish K Amara -=-=-=-=-=-=-=-=-=

Caveat note :) Number of the latency graphs in report show excessive numbers O(sec) across frame sizes w/o and with load for both VPP and DPDK. Few of us in CSIT are working on the resolution, stay tuned. For now please ignore those numbers. Cheers, Maciek > On 15 Jul 2021, at 13:03, Maciek K

Hi Damjan, +1. This proposal completely aligns with our thought process. i.e - Data structure alignment to 128B cache line and separate macro for prefetching which can be 64B or 128B depending on underlying SoC It also allow us to have single AARCH64 binary in distros for any cloud deploymen
