    Abstract: Described herein are methods and devices (e.g., routers) for performing segment routing over a multiprotocol label switching (MPLS) network. A method can include a router of the MPLS network receiving a packet, and the router modifying the packet by adding a segment routing header (SRH) type MPLS extension header. The SRH type MPLS extension header includes one or more segment identifiers (SIDs) that collectively provide a SID list for use in segment routing. The method further comprises the router copying one of the one or more SIDs in the SRH type MPLS extension header to a top of an MPLS label stack, and the router forwarding the packet as modified to another router of the MPLS network based on the one of the one or more SIDs included in a label stack entry at the top of the MPLS label stack.

    Abstract: In a memory scheduling method, a memory controller writes a first group of first row strobe commands (ACTs) into a first memory. The first group of first ACTs includes multiple first ACTs and a periodic interval exists between two adjacent first ACTs written by the memory controller into the first memory. The memory controller writes operation commands that correspond to the first group of first ACTs into the first memory after writing the first group of first ACTs into the first memory. The memory controller writes second ACTs into a second memory in periodic intervals for writing the first group of first ACTs into the first memory and/or in periodic intervals for writing the operation commands that correspond to the first group of first ACTs. The memory controller writes operation commands that correspond to the second ACTs into the second memory.

    Abstract: A DNS server comprises: a receiver configured to receive a registration request comprising a domain name, a local address, and a scope, the registration request requests registration of the domain name; a processor coupled to the receiver and configured to execute computer instructions that cause the processor to: assign an address to the domain name based on the local address and the scope, and generate a registration response comprising the address; and a transmitter coupled to the processor and configured to transmit the registration response towards an endpoint. The processor may be further configured to cache a correspondence among the domain name, the address, and the scope.

    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: A mixed Multiprotocol Label Switching (MPLS) network includes both extension header capable (EH capable) nodes and EH non-capable nodes. A first EH capable node receives advertised capabilities of a downstream node. These advertised capabilities indicate whether the downstream node is EH capable. The first EH capable node receives a packet to be transmitted to the downstream node via the MPLS network, and determines whether the packet includes an extension header (EH). The node inserts an EH label into an MPLS label stack of the packet after determining the advertised capabilities of the downstream node indicate that the downstream node is EH capable, and after determining the packet does not include the EH.

    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.
