Abstract: A mechanism for adaptively performing in-band network telemetry (INT) by a network controller is disclosed. The mechanism includes receiving one or more congestion indicators from a collector. An adjusted sampling rate is generated. The adjusted sampling rate is a specified rate of insertion of instruction headers for INT and is generated based on the congestion indicators. The adjusted sampling rate is transmitted to a head node, which is configured to perform INT via instruction header insertion into user packets.

Abstract: Embodiments of this application provide a performance measurement method and apparatus, and a system. In the method, a bit forwarding ingress router BFIR obtains a first packet, where the first packet includes an identifier of the BFIR, a bit string, and a first parameter that is used for performance measurement, the bit string is used to identify one or more bit forwarding egress routers BFERs, and the first packet is not used to transmit multicast data; and the BFIR sends the first packet to the one or more BFERs based on the bit string included in the first packet.

Abstract: A method for determining a processing capability includes: a first node sends a message to a second node. The message includes extension header processing capability information, and the extension header processing capability information is used to indicate a processing capability of the first node for an Internet Protocol (IP) version 6 (IPv6) extension header. After receiving the message, the second node obtains, based on the extension header processing capability information, the processing capability of the first node for the IPv6 extension header to determine whether the first node needs to forward or receive a packet.

Abstract: Described herein are methods and devices (e.g., routers) that add in-network services to a multiprotocol label switching (MPLS) network. A method can include a router of the MPLS network receiving a packet and modifying the packet by adding one or more MPLS extension headers, adding a header of the extension header(s), and adding an indication within an MPLS label stack that one or more MPLS extension headers have been added to the packet. The method can also include the router forwarding the packet as modified to another router of the MPLS network. In certain embodiments, an extension header label (EHL) within a label value field of a label stack entry indicates that one or more MPLS extension headers have been added to the packet. In other embodiments, a forward equivalent class (FEC) indicates that one or more MPLS extension headers follow the MPLS label stack.

Abstract: A device is disclosed for operating according to a client-server communication protocol in a communication network. The device is configured to send to or receive from another device in the communication network, a message comprising a header. The header comprises an option that includes a first Performance Measurement (PM) bit. The first PM bit indicates a first performance parameter and a second performance parameter. Further, an on-path observer entity is disclosed for a constrained application (CoAP) protocol. The on-path observer entity is configured to receive a CoAP message comprising a header from a device. The header comprises an option that includes a first PM bit. The first PM bit indicates a first performance parameter and a second performance parameter.

Abstract: A method for configuring performance measurement indication information and a related device. The method includes: a control node determines performance measurement indication information and sends a first advertisement packet in the communication network based on the BGP, where the first advertisement packet carries the performance measurement indication information, so that a plurality of forwarding nodes configure the performance measurement indication information on the plurality of forwarding nodes. In this way, when a data flow on which performance measurement is to be performed is transmitted between a plurality of different ASs, each forwarding node in the different ASs may obtain the performance measurement indication information from the first advertisement packet.
