A packet processing method includes: receiving, by a load balancing apparatus, a data packet sent by a UE; when the data packet includes historical association information, selecting, by the load balancing apparatus based on the historical association information, a service instance used to process the data packet; and sending, by the load balancing apparatus, the data packet to the selected service instance.

Systems, methods, and apparatus are disclosed for providing instant rebates before a transaction is completed. This involves ingest of customer and rebate data from two or more utilities, where the data is parsed and normalized into a standard format across all of the utilities. The customer data is then stored in an accounts database, while the rebate data is further processed along with utility rebate rules to determine a set of rebate eligibilities for a variety of scenarios. The resulting rebate profiles can be stored in a rebates database and linked to corresponding customer account data in the accounts database. Third-party frontends can then request rebate eligibility based on a customer identifier and retail channel, and various services can work in tandem to query the rebated database and return a set of eligibilities with so little latency that the eligibility check appears instant from a customer's standpoint.

A multicore electronic device is provided. The multicore electronic device includes a multicore including a plurality of cores, each core being configured to process packets in a driver core layer, a network processing core layer, and an application core layer, and a memory configured to store executions instructions for causing a first core of the plurality of cores to, when the packets are received, identify a location of a driver core for delivering the packets to an operating system domain, a location of an application core for processing the packets in a user domain, and a processing amount, determine a location of a network processing core for processing the packets based on at least one of the location of the driver core, the location of the application core, and the processing amount of the session, and control the network processing core to perform network stack processing on the packets.

Implementations of a routing tier for highly-available applications on a multi-tenant Platform-as-a-Service (PaaS) system are disclosed. A system includes a processing device to determine that, for an application running on the multi-tenant PaaS system and utilizing a first load balancer gear, a second load balancer gear is to be created for the application, and cause the second load balancer gear to be created. The processing device further to update the routing table to include information corresponding to the second load balancer gear and transmit the information associated with the second load balancer gear to a routing component of the multi-tenant PaaS system, the routing component to route traffic to the application via the first and second load balancer gears.

Some embodiments of the invention provide a novel network architecture for advertising routes in an availability zone (AZ). The novel network architecture includes a set of route servers for receiving advertisements of network addresses as being available in the AZ from different routers in the AZ. The novel network architecture also includes multiple host computers that each execute a router that (i) identifies network addresses available on the host computer, (ii) sends advertisements of the identified network addresses to the set of route servers, and (iii) receives advertisements from the set of route servers regarding network addresses available on other host computers. The identified network addresses, in some embodiments, include at least one of network addresses associated with data compute nodes (DCNs) and network addresses associated with services available at the host computer. The route servers advertise the received network addresses to other routers in the AZ.

A system is provided that includes: a first load balancing device cluster, the first load balancing device cluster includes a first load balancing device pool and a second load balancing device pool; at least one first switch respectively coupled with each load balancing device in the first load balancing device pool via a routing protocol link; and at least one second switch respectively coupled with each load balancing device in the second load balancing device pool via a routing protocol link, the at least one first switch and the at least one second switch are configured to be able to be connected with the Internet; and one of the first load balancing device pool and the second load balancing device pool is configured as a standby load balancing device pool of the other.
