[vpp-dev] a bug at jvppgen @ stable18.10, java enum type's ordinal <-> value

Hi all, The Flags show (0 1 2 3 4) by printf at 'vl_api_bridge_flags_t_handler' when calling java api(bridgeFlags). It seems to be that the ordinal of the java enum type was passed into the c function('vl_api_bridge_flags_t_handler'), not the value of the java enum type(1 2 4 8 16) . I c

Thanks Damjan for the quick response. In fact, delighted to see a response from you ( all these days, I was watching your videos ). We have a non-VPP-App which acts as a control plane entity. This will  send  session installation onto data-plane-VPP. For this communication, if we use plain UDS c

CSIT is measuring roughly 12mpps on HSW. When I measure with an equivalent system I get 10.5mpps on HSW. What I am finding is that DPDK is more efficient on CSIT HSW. CSIT Graph Node Clocks/Vector dpdk-input 6.07e1 TenGigabitEtherneta/0/0-tx 4.09e1

Hi, I'm trying to set up a multi-thread vpp middlebox with 2 NICs, dpdk+RSS. I allocated 14 worker threads and defined 7 rx-queues per interface. I see them with #show threads, and in $top, but how can i be sure that they are placed correctly on my interfaces/queues as it looks that # sh dpd

Re: [vpp-dev] Regarding IP Fragmentation

Hi, Ole Is there a general rule to set the MTU in overlay networks to avoid fragmentation? Currently I saw the interface's MTU is 9000 in VPP by default. So can we assume the intermedia router/switch to the tunnel end point can handle the jumbo frame correctly? Thus even the mtu of tunnel end

Re: [vpp-dev] Regarding IP Fragmentation

Thanks Ole. Imagine a usecase where I am getting IP packets on my graph node. I encapsulate them into an outer IP and send them out. So let's say in my example, I get IP1 and IP2. IP1 is max mtu size and IP2 is a shorter one. Perhaps they themselves are part of a fragmented flow. I now encapsulate

it's shared memory, unless vpp dies there is no reason for the connection to go down. if required, I would suggest you send periodic control pings. Quoting wangchuan...@163.com (2018-11-14 02:12:07) >worried that the connection might break. > >-

Re: [vpp-dev] ip4-load-balance

Hi Ray, By way of explanation.. without the interface the route is recursive, i.e. 20.20.20.20/24 is sent via 1.1.1.2. So the forwarding can be thought of as happening in two stages, firstly the lookup for the packet’s destination that matches 20.20.20.20/24 then the ‘lookup’ on the result of 1

Re: [vpp-dev] ipsec support for chained buffers.

Chained buffers are used when packet size is bigger than buffer size (2K). Also in some cases chained buffers may be used when packets are replicated to avoid copy of the whole payload -- Damjan > On 14 Nov 2018, at 02:24, Xuekun wrote: > > What is the chained buffer used for? For IP frag

What kind of communication exactly you need? Memif is universal packet shared memory interface, and can be used with non-vpp applications. we have lightweight library doing exactly that. See extras/libmemif in vpp repo -- Damjan > On 13 Nov 2018, at 11:52, satish.gu...@gmail.com wrote: >
