Abstract: An interworking network device receives from a first other network device associated with an MPLS domain, a route that includes a label, a prefix, and a next-hop identifier that indicates the first other network device. The interworking network device thereby generates a prefix SID attribute that includes a SID value and information indicating a structure of the SID value, wherein a LOC portion of the SID value identifies the interworking network device, and a first sub-portion of a FUNCT portion of the SID value identifies an endpoint behavior of the interworking network device in association with the first other network device. The interworking network device modifies the route to cause the next-hop identifier to indicate the interworking network device, and to cause the route to include the prefix SID attribute. The interworking network device thereby sends the route to a second other network device associated with an SRv6 domain.

Abstract: The subject technology obtains a read timestamp of a first transaction. The subject technology performs a first read operation on a parent table associated with the first transaction to determine a set of committed versions of the parent table. The subject technology determines whether a key exists in the parent table based on the first transaction. The subject technology, in response to the key existing in the parent table, performs a first write operation on a child table. The subject technology determines whether a duplicate key exists in the child table. The subject technology, in response to determining that there is no duplicate key in the child table, determines whether there is a conflict with the key. The subject technology, in response to determining that there is no conflict with the key, performs a second write operation on a secondary index table of the child table.

Abstract: The subject technology determines that a first visible version of a key is not one of a N number of newest versions of the key based on searching for the key in a regular space to locate the first visible version of the key. The subject technology performs a search of an undo space to locate a second visible version of the key. The subject technology determines whether the first visible version or the second visible version of the key is newer. The subject technology provides a newer version of the key between the first visible version and the second visible version of the key.

Abstract: Techniques are described for using route target constraint to filter routes advertised to a node in a seamless Multiprotocol Label Switching (MPLS) network. For example, a first router of a first network may generate a first border gateway protocol (BGP) message to advertise routing information for a first node of the first network, the first BGP message indicating a transport class and specifying an address-specific route target, the transport class comprising one or more tunnels to the first node that share common characteristics. In response to receiving a second BGP message originated by second node of a second network, the second BGP message comprising the address-specific route target, the first router sends the first BGP message to a second router of the second network for sending to the second node to cause the second node to import the routing information.

Abstract: A network device may receive a non-Internet protocol (non-IP) frame with a particular size and may compare the particular size to a maximum transmission unit (MTU) associated with a path between the network device and another network device. The network device may divide the non-IP frame into fragments, based on the particular size being greater than the MTU and may prepend generic fragmentation headers to the fragments to generate fragments with headers, based on the particular size being greater than the MTU. The network device may add generic fragmentation header labels and transport labels to the fragments with the headers to generate fragments with headers and labels, based on the particular size being greater than the MTU. The network device may transmit the fragments with the headers and the labels to the other network device, via the path, based on the particular size being greater than the MTU.

Abstract: In general, techniques are described for extending Mobile User Plane-Gateway architecture Border Gateway Protocol (BGP) signaling to an integrated Access Network-User Plane (ANUP) function in mobile networks. In an example, a method comprises receiving, by a computing system, a routing protocol message comprising second tunnel information for a packet data unit (PDU) session for a User Equipment (UE) and comprising data indicating a routing instance or a UE address for the User Equipment; by the computing system, based on matching the second tunnel information with first tunnel information sent or received on an interface with a mobile network control plane function, generating forwarding information to map the UE address to the PDU session or to map the PDU session to the routing instance; and based on the forwarding information, outputting, by the computing system, a packet associated with the PDU session.

Abstract: BIER architecture currently does not support anycast, in that each BIER Forwarding Router (BFR) has its own unique BFR-prefix and BFR-ID. BIER signaling protocols also check if there are duplicate BFR-IDs advertised. Anycast support with BIER is described. The description updates (e.g., relaxes and/or removes some requirements of) RFC 8279, RFC 8401, and RFC 8444.

Abstract: A router on a multicast tree, may: (a) receive a control plane message (including a label and a tree identifier identifying the multicast tree) from a downstream router on the multicast tree; (b) construct an SRv6 SID in a LOC:FUNCT:ARG form, wherein the LOC part is a locator of the downstream router and the FUNCT part is the label included in the control plane message received; and (c) create an entry in its forwarding table so that the router replicates received traffic of this multicast tree to the downstream node using the SRv6 SID. A router on a multicast tree may construct an SRv6 SID in a LOC:FUNCT:ARG form for the multicast tree, wherein the LOC is a locator of the router and the FUNCT is to be signaled to an upstream router as a label.

Abstract: The subject technology receives a query, the query including a set of statements, the set of statements including a first statement comprising a first data manipulation language operation. The subject technology determines that the set of statements includes at least one statement defining a first constraint, and a second statement indicating that the first constraint is statement deferrable for performing validation of the first constraint. The subject technology generates a key value constraint check operator as a node in a query plan. The subject technology generates a key value DML operator as a second node in the query plan, the key value DML operator corresponding to the first DML operation. The subject technology performs, using the key value constraint check operator, a validation process of the first constraint based at least in part on a set of violating keys of each DML operation from the set of statements.

Abstract: The subject technology receives a query, the query including a statement for performing a join operation on a first table and a second table. The subject technology executes, by an execution node using a generated query plan, the query. The subject technology performs, during execution of the query by the execution node, a runtime range pruning process. The subject technology determines a set of range sets for pruning, each range set including a set of columns from the first table, the set of columns being removed from undergoing a read operation as part of executing the query. The subject technology determines, based on a range bloom vector, a set of rows in a particular range set of the first table to avoid scanning in connection with the read operation. The subject technology performs the read operation based a remaining set of rows.

Abstract: A first network device may receive a first advertisement of a network destination from a second network device and may detect multihoming with the second network device. The second network device may detect the multihoming with the first network device. The first network device and the second network may enable egress protection for the multihoming. The first network device may allocate, from a first pool, a protection group identifier for a group of multihomed network devices and may allocate, from a second pool, a network destination identifier for the network destination. The first network device may provide, to a network and the second network device, a second advertisement that includes the protection group identifier and the network destination identifier. The protection group identifier and the network destination identifier may cause the network to direct traffic for the network destination, via the group of multihomed network devices.
