[vpp-dev] LACP bonding with VPP and SR-IOV

Hi, Has anyone any experience of using LACP bonding with VPP in a bifurcated setup via SR-IOV? I'm using VPP 19.08. My environment uses Mellanox ConnectX-4 25Gbps NICs in a single bond which carries data and control plane traffic via separate VLANs. It is not possible to have control plane tra

Hi Guruprasad, SCTP plugin has not been maintained in a long time and in vpp 20.05 we’ve actually removed the code. Regards, Florin > On Feb 16, 2020, at 10:25 PM, Guru Prasad wrote: > > Hi, > > Could anyone please help me on below queries: > > i)VPP_ECHO client and server application sup

[vpp-dev] CLIB_VEC64

Folks, Is anyone actually using 64-bit length vectors, controlled by #ifdef CLIB_VEC64 in vppinfra? I tend to doubt it... The original reason for this feature was to allow the vpp main heap to exceed 4gb. Since we deprecated the memory allocator responsible for the 4gb heap size limitation, I

[vpp-dev] 128k sequential read / write (fio) performance with spdk+vpp is not as good as the one with "kernel TCP"

  Hello, I'm working on  SPDK library + VPP, because some report said that VPP reduces the overhead of network. When I test with VPP (with mlx5 poll mode driver) and null device with spdk, 4k performance with VPP is much better than the default(kTCP). But, 128k write performance with VP

[vpp-dev] Regarding SCTP support in VPP host stack

Hi, Could anyone please help me on below queries: i)VPP_ECHO client and server application supports testing of SCTP stack? ii) How stable SCTP stack in vpp1908. iii) Is VPP SCTP stack RFC compliant? iv) What is the current performance numbers with VPP SCTP stack. Thanks in Advance, Guruprasad T

[vpp-dev] RFC: FD.io Summit (Userspace), September, Bordeaux France

Hi folks, A 2020 FD.io event is something that has been discussed a number of times recently at the FD.io TSC. With the possibility of co-locating such an event with DPDK Userspace, in Bordeaux, in September. Clearly, we are incredibly eager to make sure that such an event would be a success.
