Examples may include techniques to control an insertion ratio or rate for a cache. Examples include comparing cache miss ratios for different time intervals or windows for a cache to determine whether to adjust a cache insertion ratio that is based on a ratio of cache misses to cache insertions.

A system that includes a routing device and a proxy server in a private network. The routing device configures itself to route data traffic for a network device within a private network using private links. The routing device forwards an access request requesting access to a destination address in a public network from the network device to the proxy server. The proxy server determines whether the access request satisfies a set of access rules and generates an access request response. The routing device forwards the access request response from the proxy server to the network device. The routing device configures itself to route data traffic between the network device and the destination address using public links in response to receiving an access approval message. The routing device communicates data traffic between the network device and the destination address using public links.

A first map request message is sent from a source network device to a mapping network device to determine a destination network device associated with a destination endpoint device and a security association between the source network device and the destination network device. A first response message is received at the source network device that includes data indicating a mapping between the destination network device and the destination endpoint device and data indicating a security association between the source network device and the destination network device. The data is stored at the source network device. A second map request message is sent from the source network device to the mapping network device to update the data indicative of the mapping or the security association. A second response message is received at the source network device from the mapping network device.

Systems and methods are described to enable the load-balanced use of globalized network addresses, addressable throughout a network to access a network-accessible service. A set of global access points are provided, which advertise availability of the globalized network addresses. On receiving a request to access a network-accessible service, a global access point can select an endpoint for the service from among a number of data centers, based on a desired distribution of traffic among the data centers. The access point then forwards the traffic to the selected endpoint. In one embodiment, the access point applies network address translation to enable the traffic to be routed to the endpoint without terminating a connection at the endpoint. The access point may use a variety of techniques to ensure resiliency of the network and knowledge of available endpoints.

A network element includes multiple ports, a memory, multiple processors and cache-flushing circuitry. The multiple ports are configured to serve as ingress and egress ports for receiving and transmitting packets from and to a network. The memory is configured to store a forwarding table including rules that specify forwarding of the packets from the ingress ports to the egress ports. The multiple processors are configured to process the packets in accordance with the rules. The two or more cache memories are each configured to cache a respective copy of one or more of the rules, for use by the multiple processors. The cache-flushing circuitry is configured to trigger flushing operations of copies of rules in the cache memories in response to changes in the forwarding table, and to reduce a likelihood of simultaneous accesses to the forwarding table for updating multiple cache memories, by de-correlating or diluting the flushing operations.

Methods and apparatus for software-defined coherent caching of pooled memory. The pooled memory is implemented in an environment having a disaggregated architecture where compute resources such as compute platforms are connected to disaggregated memory via a network or fabric. Software-defined caching policies are implemented in hardware in a processor SoC or discrete device such as a Network Interface Controller (NIC) by programming logic in an FPGA or accelerator on the SoC or discrete device. The programmed logic is configured to implement software-defined caching policies in hardware for effecting disaggregated memory (DM) caching in an associated DM cache of at least a portion of an address space allocated for the software application in the disaggregated memory. In connection with DM cache operations, such as cache lines evicted from a CPU, logic implemented in hardware determines whether a cache line in a DM cache is to be convicted and implements the software-defined caching policy for the DM cache including associated memory coherency operations.

The following description is directed to managing routing resources of a communication network. In one example, a method can include determining an amount of routing capacity from a network device and toward a routing prefix. An attribute associated with the routing prefix can be modified based on the amount of routing capacity toward the routing prefix. The modified attribute associated with the routing prefix can be announced to a peer of the network device.

A system, process, and computer-readable medium for updating an application cache using a stream listening service is described. A stream listening service may monitor one or more data streams for content relating to a user. The stream listening service may forward the content along with time-to-live values to an application cache. A user may use an application to obtain information regarding the user's account, where the application obtains information from a data store and/or cached information from the application cache. The stream listening service, by forwarding current account information, obtained from listening to one or more streams, to the application cache, reduces traffic at the data store by providing current information from the data stream to the application cache.

The embodiments of the present disclosure provide a data packet processing method and apparatus, a storage medium and an electronic device. The method includes that: a Bit Index Explicit Replication (BIER) Multicast Identifier (BMID) information of a data packet is set, wherein the BMID information is used for indicating a multicast channel to which the data packet belongs; and the BMID information is sent to a Bit-Forwarding Ingress Router (BFIR). Through the solution in the embodiments of the present disclosure, the technical problem in the related art that a node receives duplicate data packets is solved, duplicate data packets may be prevented, and data transmission efficiency is improved.

A data or packet processing device such as a network interface controller may include cache control logic that is configured to obtain a set of memory descriptors associated with a queue from the memory. The set of descriptors can be stored in the cache. When a request for processing a data packet associated with the queue is received, the cache control logic can determine that the cache is storing memory descriptors for processing the data packet, and provide the memory descriptors used for processing the packet.
