Release v1.0.8 (2017-11-21)

Compatibility

VPP version v18.01-rc0-309-g70bfcaf

Major Themes

  • [cn-infra]
    • updated to version 1.0.7

New Features

  • ifplugin
    • ability to configure STN rules. See respective readme in interface plugin for more details.
    • rx-mode settings can be set on interface. Ethernet-type interface can be set to POLLING mode, other types of interfaces supports also INTERRUPT and ADAPTIVE. Fields to set QueueID/QueueIDValid are also available
  • l4plugin
    • added new l4 plugin to the VPP plugins. It can be used to enable/disable L4 features and configure application namespaces. See respective readme in L4 plugin for more details.
    • support for VPP plugins/l3plugin ARP configuration. The configurator can perform the basic CRUD operation with ARP config.

Defaultplugins

  • ifplugin
    • added possibility to add interface to any VRF table.
  • resync
    • resync error propagation improved. If any resynced configuration fails, rest of the resync completes and will not be interrupted. All errors which appears during resync are logged after.
  • added defaultpligins API.
  • API contains new Method DisableResync(keyPrefix ...string). One or more ETCD key prefixes can be used as a parameter to disable resync for that specific key(s).

Linuxplugin

  • l3plugin
    • route configuration do not return error if required interface is missing. Instead, the route data are internally stored and configured when the interface appears.

GOVPP

  • delay flag removed from GoVPP plugin

Documentation

  • improved in multiple vpp-agent packages

Minor fixes/improvements

  • removed deadlinks from README files

Release v1.0.7 (2017-10-30)

Compatibility

VPP version v18.01-rc0~154-gfc1c612

Major Themes

  • [cn-infra]

    • updated to version 1.0.6

  • Default VPP plugin

    • added resync strategies. Resync of VPP plugins (defaultplugins) can be set using defaultpluigns config file; Resync can be set to full (always resync everything) or dependent on VPP configuration (if there is none, skip resync). Resync can be also forced to skip using parameter. See appropriate changelog in Defaultplugins for details.

New Features

  • Linuxplugins L3Plugin
    • added support for basic CRUD operations with static Address resolution protocol entries and static Routes.

Release v1.0.6 (2017-10-17)

Major Themes

  • [cn-infra]
    • updated to version 1.0.5
  • LinuxPlugin
    • Configuration of vEth interfaces modified. Veth configuration defines two names: symbolic used internally and the one used in host OS. HostIfName field is optional. If it is not defined, the name in the host OS will be the same as the symbolic one - defined by Name field.

Release v1.0.5 (2017-9-26)

Compatibility

VPP version v17.10-rc0~334-gce41a5c

Major Themes

  • [cn-infra]
    • updated to version 1.0.4
  • GoVppMux
    • configuration file for govpp added
  • Kafka Partitions
    • Changes in offset handling, only automatically partitioned messages (hash, random) have their offset marked. Manually partitioned messages are not marked.
    • Implemented post-init consumer (for manual partitioner only) which allows to start consuming after kafka-plugin Init()
    • Minimalistic examples & documentation for Kafka API will be improved in a later release.

Release v1.0.4 (2017-09-08)

Major Themes

  • Kafka Partitions
    • Implemented new methods that allow to specificy partitions & offset parameters:
      • publish: Mux.NewSyncPublisherToPartition() & Mux.NewAsyncPublisherToPartition()
      • watch: ProtoWatcher.WatchPartition()
    • Minimalistic examples & documentation for Kafka API will be improved in a later release.
  • Flavors
  • [goVpp]
    • updated version waits until vpp is ready to accept a new connection

Release v1.0.3 (2017-09-05)

Major Themes

Enabled support for wathing data store OfDifferentAgent() - see:

Preview of new Kafka client API methods that allows to fill also partition and offset argument. New methods implementation ignores these new parameters for now (fallbacking to existing implementation based on github.com/bsm/sarama-cluster and github.com/Shopify/sarama).

Compatibility

VPP version v17.10-rc0~265-g809bc74 (upgraded because of VPP MEMIF fixes).

Release v1.0.2 (2017-08-28)

Major Themes

Algorithms for applying northbound configuration (stored in ETCD key value data store) to VPP in the proper order of VPP binary API calls implemented in Default VPP plugin:

  • network interfaces, especially:
    • MEMIFs (optimized dataplane network interface tailored for a container to container network connectivity)
    • VETHs (standard Linux Virtual Ethernet network interface)
    • AF_Packets (for accessing VETHs and similar type of interface)
    • VXLANs, Physical Network Interfaces, loopbacks ...
  • L2 BD & X-Connects
  • L3 IP Routes & VRFs
  • ACL (Access Control List)

Support for Linux VETH northbound configuration implemented in Linux Plugin applied in proper order with VPP AF_Packet configuration.

Data Synchronization during startup for network interfaces & L2 BD (support for situation when ETCD contain configuration before VPP Agent starts).

Data replication and events:

  • Updating operational data in ETCD (VPP indexes such as sw_if_index) and statistics (port counters).
  • Updating statistics in Redis (optional once redis.conf available - see flags).
  • Publishing link up/down events to Kafka message bus.

Miscellaneous:

  • Examples
  • Tools:
    • agentctl CLI tool that show state & configuration of VPP agents
    • docker: container-based development environment for the VPP agent
  • other features inherited from cn-infra:
    • health: status check & k8s HTTP/REST probes
    • logging: changing log level at runtime

Extensibility & integration

Ability to extend the behavior of the VPP Agent by creating new plugins on top of VPP Agent flavor. New plugins can access API for configured: VPP Network interfaces, Bridge domains and VETHs based on idxvpp threadsafe map tailored for VPP data with advanced features (multiple watchers, secondary indexes).

VPP Agent is embeddable in different software projects and with different systems by using Local Flavor to reuse VPP Agent algorithms. For doing this there is VPP Agent client version 1:

  • local client - for embedded VPP Agent (communication inside one operating system process, VPP Agent effectively used as a library)
  • remote client - for remote configuration of VPP Agent (while integrating for example with control plane)

Known Issues

A rarely occurring problem during startup with binary API connectivity. VPP rejects binary API connectivity when VPP Agent tries to connect too early (plan fix this behavior in next release).

Compatibility

VPP version v17.10-rc0~203
