<p>Szia,</p>
<p>Az Intelesek nem adtak semmilyen feedbacket. Esetleg fel lehetne
nekik vetni, hogy csütörtökön beszéljünk 14-15 vagy 15-16 között,
ha neked is jó Gergő? Utóbbi lehet, hogy jobb, mert akkor előtte
mi is tudunk beszélni.</p>
<p>Üdv.<br>

lehet a sima counter-eknél profibb dolgokat beletenni a
vswitch-be, még egy kicsit ajánlgattam nekik az ERFS API-t
is, ahol tudnak saját kódot betenni a pipeline-ba, és azt
experimenter action-nel konfigolni, de aztán eddig már nem
jutottunk el. Érdekes felvetés az, amit ír, szerintem a P4
extern az kb. épp jó is lenne nekik, bár nyilván meg kéne
pontosabban érteni, hogy mit csinálnának, pl. ha sok gépidőt
igényel az algoritmusuk, akkor lehet, praktikus külön szálra
tenni, és queue-kon keresztül kommunikálni, és/vagy sorsolni
x% packet-et, és csak azokra meghívni az ő rutinjukat (de
itt ugye vigyázni a reorder-re…)<o:p></o:p></span></p>

(<a class="moz-txt-link-freetext" href="http://connect.linaro.org/">http://connect.linaro.org/</a>), amire meghívtak előadni.
Elsősorban a P4/ODP-n volt a fókusz (ez érdekelte őket), de
egyértelműen beemeltem a P4/DPDK eredményeket is, illetve
tettem utalást a Freescale-es munkájára Petinek. Csatolom a
prezit. Egyik hozzászólót (ha jól emlékszem, Freescale-es
arc) különösen érdekelték a komplexebb use case-ek,
olyannyira, hogy kérdezte, lehet-e csatlakozni a projekthez.
Említettem neki az EIT kezdeményezést. Többen mondták, hogy
nagyon szívesen segítenek pl. a performance tuningolásban.
Én meglepődtem, mennyire jó fogadtatása volt a prezinek, de
persze majd meglátjuk, hogy az ígéretek tettekben is
realizálódnak-e.<o:p></o:p></span></p>

<p class="MsoNormal">One of the main challenges towards
programmable networks is related to scalable monitoring or
network observability. Current OF mechanisms and switches
do not allow for local deployment of observability points
(or monitoring processes) which severely limits the
granularity and usefulness of the monitoring information,
among other things. Another challenge regards effective
deployment mechanisms and implementation of observability
capabilities in a switch with low processing overhead to
avoid bottlenecks caused by monitoring.<o:p></o:p></p>

<div>
<p class="MsoNormal">So far we have developed the concept of
observability points in terms of a light-weight
low-complexity model for predicting persistent congestion
episodes at buffer fill time, using only two data plane
counters. The offer and interest in a potential
collaboration is to take this concept further into
implementing relevant mechanisms needed for enabling and
supporting observability of programmable networks by
flexible deployment of monitoring mechanisms. Being able
to define and deploy observability points by the use of P4
and a compiler without modifying the switch kernel could
be an interesting case and a step further.<o:p></o:p></p>
