Flexible traffic control for EVPN
Systems and methods include receiving one or more Ethernet Virtual Private Network (EVPN) advertisements from one or more peer nodes with information including any of traffic characterization information and traffic control information; and providing traffic to the EVPN and to the corresponding one or more peer nodes based on the information from the corresponding one or more peer nodes. The one or more EVPN advertisements can be in an EVPN Network Layer Reachability Information (NLRI) advertisement, and the EVPN NLRI can have Route Type 1 for the information to apply to an EVPN Instance (EVI) and the EVPN NLRI can have Route Type 2 for the information to apply to a specific customer node based on a Media Access Control (MAC).
1. A node comprising:
a plurality of ports connected to one or more customer nodes and to one or more peer nodes;
a switching fabric configured to switch traffic between the plurality of ports; and
a controller configured to
obtain one or more Ethernet Virtual Private Network (EVPN) advertisements from the one or more peer nodes for an EVPN with information including traffic characterization information and traffic control information that includes Traffic Class and Drop Precedence, and
cause transmission of the traffic to the EVPN and to the corresponding one or more peer nodes based on the information from the corresponding one or more peer nodes,
wherein the one or more EVPN advertisements are in an EVPN Network Layer Reachability Information (NLRI) advertisement, and wherein the EVPN NLRI has Route Type 1 for the information to apply to an EVPN Instance (EVI) and the EVPN NLRI has Route Type 2 for the information to apply to a specific customer node based on a Media Access Control (MAC), and
wherein the information is used for policing and shaping on any of a EVI basis and a per MAC and per EVI basis.
2. The node of claim 1 , wherein the one or more EVPN advertisements are in an optional Border Gateway Protocol (BGP) attribute.
3. The node of claim 1 , wherein the traffic characterization information includes any of Committed Information Rate (CIR), Excess Information Rate (EIR), and Committed Burst Size (CBS).
4. A non-transitory computer-readable medium having instructions stored thereon for programming one or more processors in a node to perform steps of:
receiving one or more Ethernet Virtual Private Network (EVPN) advertisements from one or more peer nodes for an EVPN with information including traffic characterization information and traffic control information that includes Traffic Class and Drop Precedence; and
providing traffic to the EVPN and to the corresponding one or more peer nodes based on the information from the corresponding one or more peer nodes,
wherein the one or more EVPN advertisements are in an EVPN Network Layer Reachability Information (NLRI) advertisement, and wherein the EVPN NLRI has Route Type 1 for the information to apply to an EVPN Instance (EVI) and the EVPN NLRI has Route Type 2 for the information to apply to a specific customer node based on a Media Access Control (MAC), and
wherein the information is used for policing and shaping on any of a EVI basis and a per MAC and per EVI basis.
5. The non-transitory computer-readable medium of claim 4 , wherein the one or more EVPN advertisements are in an optional Border Gateway Protocol (BGP) attribute.
6. The non-transitory computer-readable medium of claim 4 , wherein the traffic characterization information includes any of Committed Information Rate (CIR), Excess Information Rate (EIR), and Committed Burst Size (CBS).
7. A method comprising:
receiving one or more Ethernet Virtual Private Network (EVPN) advertisements for an EVPN from one or more peer nodes with information including traffic characterization information and traffic control information that includes Traffic Class and Drop Precedence; and
providing traffic to the EVPN and to the corresponding one or more peer nodes based on the information from the corresponding one or more peer nodes
wherein the one or more EVPN advertisements are in an EVPN Network Layer Reachability Information (NLRI) advertisement, and wherein the EVPN NLRI has Route Type 1 for the information to apply to an EVPN Instance (EVI) and the EVPN NLRI has Route Type 2 for the information to apply to a specific customer node based on a Media Access Control (MAC), and
wherein the information is used for policing and shaping on any of a EVI basis and a per MAC and per EVI basis.
8. The method of claim 7 , wherein the one or more EVPN advertisements are in an optional Border Gateway Protocol (BGP) attribute.
9. The method of claim 7 , wherein the traffic characterization information includes any of Committed Information Rate (CIR), Excess Information Rate (EIR), and Committed Burst Size (CBS).
