MANDATORY REQUIREMENTS |
|||
| Interface fibs | We need fib (VRF, really) to be applied to any interface. This simplifies CE-PE implementation (ipfw setfib is not needed) and enables AToM. ether_input(), vlan_ether_input() and all other related L2 input routines (e.g. tun/tap/gif/gre/ng_iface/etc..) will be affected. Kernel interface and interface flag is also needed. This will probably be done with ifconfig | wiki | 100% |
| In-kernel label storage (lfib) | We need the possibility to get/set MPLS lfib information (add/remove/assign label) | wiki | 80% |
| Simple hash for AF_MPLS instead of RADIX | Hash table and very simple hash function should improve label switching performace | wiki | 10% |
| MPLS unicast input/output | We need PE router implementation (e.g. pass packets to/from MPLS cloud) plus simple MPLS forwarding | wiki | 30% |
| Routing socket | kern/134931 and ABI keeping are showstoppers. We need FIB and MPLS info in routing messages | wiki | 60% |
| Reasonable amount of fibs | At the moment, only 16 fibs can be used | x | 10% |
| MPLS traceroute | Normal network diagnosting tools will not work (as expected) in MPLS domain. We should implement RFC 4379 (Detecting Multi-Protocol Label Switched (MPLS) Data Plane Failures) and? RFC 4950 (ICMP Extensions for Multiprotocol Label Switching) |
x | 0% |
| Netgraph: ng_mpls | Pass AF_MPLS mbufs to netgraph nodes based on local label | wiki | 55% |
| Netgraph: ng_setfib | Just for testing and binding | wiki | 95% |
| bird: LDP | Implement LDP RFC 5036 protocol in BIRD routing software | wiki | 80% |
| bird: multiprotocol core | Implement general support for abstact address tables (MPLS, VPNvX) | wiki | 100% |
Layer 3 VPNS |
|||
| Kernel: L3VPNs | Permit L3 VPN label popping without routing lookup | wiki | 30% |
| Netgraph: ng_netflow | VRF-aware traffic accounting | wiki | 99% |
| bird: BGP L3 VPNS (VPNv4) | Implement VPN extensions described in RFC 4364 | x | 80% |
| bird: BGP L3 VPNS (VPNv6) | Implement VPN extensions described in RFC 4364 | x | 10% |
| bird: L3VPN protocol | Implement l3vpn protocol for VPNvX routes convertation | x | 80% |
| bird: protocols interaction | Implement protocols interaction (request LDP labels for prefixes) | x | 99% |
AToM / VPLS |
|||
| Netgraph: ng_eompls | Node popping/pushing tunnel label and EoMPLS header | wiki | 10% |
MPLS QoS |
|||
| Netgraph: ng_car | Implement packet color marking via mbuf tags | wiki | 10% |
| Netgraph: ng_qc | Qos classifier (IP ToS, IP DSCP, MPLS TC -> DSCP mbuf) | wiki | 10% |
| Netgraph: ng_qa | Apply Traffic class policy found in mbuf_tag | wiki | 10% |
Traffic Engineering |
|||
| Netgraph: ng_te | Netgraph-base TE interfaces | wiki | 0% |
OTHER |
|||
| MPLS multicast input/output | We have to implement it some day.. | x | 0% |
| IPv6 fib support | We definitely needs this | x | 99% |
