+ | 1. NSH_SFC 17.07 released last week after feature test for both VxLAN-GPE and Eth transports. | ||
+ | 2. NSH patch is merged to the OVS-DPDK mainline to hit OVS 2.8 release. Thanks Jan Scheurich (Ericsson) and Yi Yang(Intel) | ||
+ | and several others for excellent collaboration to make it an acceptable solution in OVS community. We believe this could | ||
+ | accelerate the industry to embrace NSH based SFC solution via open source community projects (e.g. OVS, VPP, OpenDaylight, | ||
+ | OPNFV, ONAP). Yi Yang is working on the NSH patch for net-next now. | ||
+ | |||
+ | 17.10 new features | ||
+ | 1. NSH_SFC performance automation test enablement | ||
+ | 2. NSH TTL field and manipulation introduced in recent NSH draft | ||
+ | 3. Offload NSH traffic steering to NSH-aware NIC (stretch goal) | ||

+ | 1) NSH_SFC presentation on FD.io mini-summit and Nirvana day at Openstack summit. | ||
+ | 1.1) Slides uploaded at https://wiki.fd.io/view/File:NSH_SFC_Openstack_Fdio_Minisummit_widescreen_v3.pdf which contains | ||
+ | the NSH_SFC internals as well performance data which clearly suggests that VxLAN-GPE impacts 1C1T performance, and | ||
+ | vhost_user impacts end-to-end SFC throughput as it does not scale for supporting massive EW traffics even more cores | ||
+ | are assigned. | ||

+ | 1) NSH_SFC integration with VPP 17.04 | ||
+ | 1.1) Fix two bugs for NSH_SFC 17.04-RC2 | ||
+ | 1.1.1) https://gerrit.fd.io/r/#/c/6358/ Remove unsed parameter | ||
+ | from fib_table_entry_special_add(). | ||
+ | 1.1.2) https://gerrit.fd.io/r/#/c/6359/ Fix dual-loop issue of NSH-SNAT. | ||
+ | 1.2) A recent VPP bug fix of “MAC address check” cause the failure of NSH-aware SNAT feature in NSH_SFC plugin. Hongjun raised this to VPP community for a solution. | ||
+ | |||
+ | 2) NSH_SFC 17.04 release | ||
+ | 2.1) Will ask test team to perform functional testing using VPP 17.04 using NSH_SFC RC2, once the above incomparability issue is fixed | ||
+ | 2.2) Target release date is April 28, 2017. | ||
+ | |||
+ | 3) NSH_SFC 17.07 feature development plan | ||
+ | 3.1) Support Geneve and Eth as NSH transports, for compliance with IETF approved next generation tunneling protocol as well as high performance transport respectively | ||
+ | 3.2) Performance automation test integration to VNF, by leveraging Trex | ||
+ | 3.3) Performance optimization of NSH_SFC for end-to-end throughput as well as reduce maximum latency. | ||
+ | 3.4) Real NSH-aware VNF by enabling NSH_SFC plugin to pass per-packet metadata to real SF (stretch goal) | ||

+ | 1) Open | ||
+ | |||
+ | HC API freeze tomorrow, Hongjun will submit a patch that contains a Yang model for new | ||
+ | APIs supporting MD Type 2 before API freeze. | ||
+ | |||
+ | 2) How to enable iOAM based on initial MD Type 2 support patch? | ||
+ | MD Type 2 patches are merged, after tests cases of using iOAM initial patches from Prasad passed. | ||
+ | Rely on Prasad to submit patches to enable iOAM over NSH, the handler for push/pop/swap/traces | ||
+ | are already supported. | ||
+ | |||
+ | 3) Status and plan for NSH-aware VNF by collocating Proxy and SF. | ||
+ | Ingress packets after NSH and VxLAN de-capsulation could be processed by SNAT, after VPP fixed | ||
+ | a issue. Now blocked by the packets cannot be routed back to the NSH_SFC plugin for re-encapsulation. | ||
+ | Hongjun figured out a solution to use install a forwarding rule into the IPv4 lookup graph node to | ||
+ | forward packets to a virtual port connecting to the NSH_SFC. | ||
+ | Since there is no changes to the SNAT module so it could easily scale for other SFs in the VPP. | ||
+ | Initial patches will be developed and submitted this week, and it should have no blocking issue to | ||
+ | hit 17.04 release. | ||
+ | |||
+ | 4) NSH_SFC performance data review and CSIT enabling plan CSIT team has measured performance of the | ||
+ | NSH_SFC, the single core and core scaling performance are pretty good, but the maximum latency is | ||
+ | unusually much bigger than VPP, WIP root-causing the issue. | ||

+ | 1) Open | ||
+ | |||
+ | - OpenDaylight patches for enabling NSH_SFC based classifier has been merged, after reporting several HC issues which are fixed recently. | ||
+ | Testing the existing ODL code for NSH_SFC based Proxy is ongoing. Basically, goal to enable ODL Carbon to support NSH_SFC based SFF, Classifier | ||
+ | and Proxy is in good shape. | ||
+ | |||
+ | 2) Status of 17.04 development | ||
+ | |||
+ | - Initial MD Type 2 support: v10 patch submitted, Prasad has comments to it and Hongjun is working on consolidating comments. | ||
+ | |||
+ | - NSH-aware VNF: no progress yet, will be working on it this week. | ||
+ | |||
+ | 3) NHS_SFC 17.01 performance measurement | ||
+ | |||
+ | - Single core performance for NSH_SFC based SFF, Classifier and Proxy ongoing, Classifier performance is about 2x then SFF and Proxy due to | ||
+ | only 1 encapsulation operation, and SFF and Proxy needs at least 2 de-capsulation/re-encapsulation. | ||
+ | |||
+ | - Core scaling testing does not show linear scaling due to test configuration problem, issue root caused and re-testing ongoing. | ||

+ | |||
+ | 1.1) Two issues (missing next node and hton endian) founded during integration tests, so it is very important to enable CSIT automation | ||

+ | |||
+ | 2.1) Co-locate NSH_SFC and VPP in a same box, blocked on a issue on handling packets returned from SNAT node to NSH_SFC plugin, prefer solution is to connect them to a L2 bridge instead of SNAT directly transmit the packet to wire. Hongjun is working on this | ||
+ | |||
+ | 2.2) Plan for the MD type 2 support and iOAM support based on discussion between Hongjun and Prasad | ||
+ | |||
+ | 2.2.1) Generic TLV routines in NSH_SFC, initial patches to send out for review this week | ||
+ | |||
+ | 2.2.2) iOAM plugin by Prasad to reuse those routines for NSH based iOAM implementation | ||
+ | |||

+ | 1) A small patch https://gerrit.fd.io/r/#/c/4745/ applied to NSH_SFC RC1, hence NSH_SFC RC2 tag is created. NSH_SFC RC2 integration test with VPP 17.01 and Honeycomb RC2 (https://gerrit.fd.io/r/#/c/4781/) is ongoing, blocked on environment configuration. Expect to release NSH_SFC 17.01 by Jan 27th , once integration test passed, and Honeycomb 17.01 depends on NSH_SFC 17.01. | ||
+ | |||
+ | 2) Shared preliminary NSH_SFC performance using RC2 to cover SFF, Proxy and Classifier use cases by feeding small packets. See details at https://wiki.fd.io/view/NSH_SFC/Docs/Performance | ||
+ | |||
+ | a) The comprehensive performance report will be shared once CSIT team fully integrate it to CSIT automation test environment. | ||
+ | |||
+ | b) NSH Proxy (1core, 1thread) performance drops from 16.09’ 5.8Mpps to 4.25Mpps for 128B small packet, might due to decoupling of VxLAN-GPE and NSH, will be analyzing it further post 17.04 release after MD Type 2 is supported. | ||
+ | |||
+ | c) 2 to 3 dedicated cores could achieve 10G line rate for small packet for all NSH_SFC use cases, assuming performance scales linearly. | ||

+ | 1) NSH_SFC build failure tracked by https://jira.fd.io/browse/NSHSFC-18, which caused by recent | ||
+ | build infrastructure change. Hongjun is working with Damjan to resolve this, seems it only need | ||
+ | to add the missed file to the file src/vpp-api/java/Makefile.am. Nobody knows how to publish | ||
+ | NSH_SFC artifacts for NSH_SFC rc1. | ||
+ | |||
+ | AR: Danny to drop email to help desk to ask how to publish NSH_SFC artifacts. | ||
+ | |||
+ | 2) 0.5 dedicated resource is working on including NSH_SFC to the FD.io CSIT tests to cover both | ||
+ | feature and performance automation tests. Goals are: | ||
+ | * Can configure the NSH_SFC to act as SFF/Classifier/Proxy via Postman | ||
+ | * Enable a Jeinkins job that drives TREX to send traffics in different size to NSH_SFC and | ||
+ | measure/report the NSH_SFC performance when it acts different roles. | ||
+ | |||
+ | Test plan is underdeveloped, and the initial version is supposedly to be ready by the end of this | ||
+ | week. Target is that the CSIT infrastructure for NSH_SFC to hit 17.04 release. All the new patches | ||
+ | to be submitted in the future will benefit from this automation performance tests, to understand | ||
+ | the performance impact the patch will be introducing. | ||
+ | |||
+ | 3) A separated meeting is schedule with Prasad to discuss the TLV support for NSH MD Type 2. Prasad | ||
+ | and his team is doing the in-band IOAM for VxLAN-GPE at this point which enables a framework to handle | ||
+ | TLV. Target is to ensure common TLV parser in VPP could be used by various VPP plugin for different | ||
+ | purpose. Keith is going to raise this in the VPP weekly meeting. | ||
