Feature Details:

ACL Based Forwarding

Maintainer: Neale Ranns nranns@cisco.com

  • Policy Based Routing

  • ACLs match traffic to be forwarded

  • Each rule in the ACL has an associated ‘path’ which determines how the traffic will be forwarded. This path is described as a FIB path, so anything possible with basic L3 forwarding is possible with ABF (with the exception of output MPLS labels)

  • ACLs are grouped into a policy

  • ACL priorities within the policy determine which traffic is preferentially matched

  • Policies are attached to interfaces.

  • ABF runs as an input feature in the L3 path

Feature maturity level: production
Supports: API CLI MULTITHREAD
Source Code: https://github.com/FDio/vpp/blob/master/src/plugins/abf

ACLs for Security Groups

Maintainer: Andrew Yourtchenko ayourtch@gmail.com

The ACL plugin allows to implement access control policies at the levels of IP address ownership (by locking down the IP-MAC associations by MACIP ACLs), and by using network and transport level policies in inbound and outbound ACLs. For non-initial fragments the matching is done on network layer only. The session state in stateful ACLs is maintained per-interface (e.g. outbound interface ACL creates the session while inbound ACL matches it), which simplifies the design and operation. For TCP handling, the session processing tracks “established” (seen both SYN segments and seen ACKs for them), and “transient” (all the other TCP states) sessions.

  • Inbound MACIP ACLs

    • filter the source IP:MAC address statically configured bindings

  • Stateless inbound and outbound ACLs

    • permit/deny packets based on their L3/L4 info

  • Stateful inbound and outbound ACLs

    • create inbound sessions based on outbound traffic and vice versa

Adjacency

Maintainer: Neale Ranns nranns@cisco.com

Adjacencies represent the next-hop information required to reach a directly connected neighbour.

  • An adjacency represents how to send different traffic types to a peer

  • The principles properties of an adjacency are the interface and rewrite. The rewrite will be prepended to the packet as it is forward through the interface.

  • The rewrite is provided either by the interface type. It can be constructed either from fixed interface properties (i.e. src,dst IP address on a P2P tunnel) or from a resolution protocol (like ARP on an Ethernet link).

  • An Adjacency is said to be complete when the rewrite is present and incomplete when it is not,

  • An adjacency that is a leaf in the DPO graph is terminal/normal (i.e on a physical interface). When not terminal it is termed a midchain (i.e. one on a virtual interface, e.g. GRE tunnel). Midchain adjacencies can be stacked/joined onto the the DPO graph that described subsequent forwarding (i.e. how to send the the GRE tunnel’s destination address).

  • Glean adjacencies describe how to broadcast packets onto a subnet

Linux Control Plane (integration)

Maintainer: Neale Ranns neale@grahpiant.com

This plugin provides the beginnings of an integration with the Linux network stack. The plugin provides the capability to ‘mirror’ VPP interfaces in the Linux kernel. This means that for any interface in VPP the user can create a corresponding TAP or TUN device in the Linux kernel and have VPP plumb them together. The plumbing mechanics is different in each direction. In the RX direction, all packets received on a given VPP interface that are punted (i.e. are not dropped or forwarded) are transmitted on its mirror interface (this includes for example ARP, ND etc, so the recommendation is to disable ARP, ND, ping plugin). In the TX direction, packets received by VPP an the mirror Tap/Tun are cross-connected to the VPP interfaces. For IP packets, IP output features are applied. This is the beginnings of integration, because there needs to be an external agent that will configure (and synchronize) the IP configuration of the paired interfaces.

Policy 1:1 NAT

Maintainer: Ole Troan ot@cisco.com

Match packet against rule and translate according to given instructions. Rules are kept in a flow cache bihash. Instructions in a pool of translation entries. For a given interface/direction all rules must use the same lookup mask. E.g. SA + SP. A dynamic NAT would punt to slow path on a miss in the flow cache, in this case the miss behaviour is configurable. Default behaviour is pass packet along unchanged.

Session Layer

Maintainer: Florin Coras fcoras@cisco.com

The session layer facilitates the interaction between northbound applications and southbound transport protocols. To this end, northbound, through the app-interface sub layer, the session layer exposes APIs for applications to interact with abstract units of communication, i.e., sessions. And southbound, through the transport protocol interface, it exposes APIs that allow transport protocols to exchange data and events (ctrl and io) with applications, without actually being aware of how that communication is carried out.

  • Manages allocation and tracking of sessions (6-tuple lookup tables)

  • App namespaces that constrain application access to network resources

  • Conveys data and notifications (ctrl and io) between transport protocols and apps

  • Transport protocol interface

    • Provides generic transport protocol template

    • Converts between transport and application representation of data

    • Schedules sessions/connections for sending

  • Application interface

    • Maintains per application state

    • Manages allocation of shared memory resources used for exchanging data between applications and transports

    • Exposes a native C and a binary api for builtin and external apps respectively
