Abstract: A two-level main memory in which both volatile memory and persistent memory are exposed to the operating system in a flat manner and data movement and management is performed in cache line granularity is provided. The operating system can allocate pages in the two-level main memory randomly across the first level main memory and the second level main memory in a memory-type agnostic manner, or, in a more intelligent manner by allocating predicted hot pages in first level main memory and predicted cold pages in second level main memory. The cache line granularity movement is performed in a “swap” manner, that is, a hot cache line in the second level main memory is swapped with a cold cache line in first level main memory because data is stored in either first level main memory or second level main memory not in both first level main memory and second level main memory.

Abstract: Symmetric networking techniques disclosed herein can be applied by gateway routers in cloud networks. The techniques can ensure that both outbound traffic received at a cloud from a branch device and return traffic directed from the cloud back to the branch device are processed by a same gateway router. The gateway router can use network address translation to insert IP addresses from an inside pool and an outside pool assigned to the router.

Abstract: A logical routing element (LRE) having multiple designated instances for routing packets from physical hosts (PH) to a logical network is provided. A PH in a network segment with multiple designated instances can choose among the multiple designated instances for sending network traffic to other network nodes in the logical network according to a load balancing algorithm. Each logical interface (LIF) of an LRE is defined to be addressable by multiple identifiers or addresses, and each LIF identifier or address is assigned to a different designated instance.

Abstract: According to certain embodiments, a method by a network device includes receiving a handshake message for a traffic flow from a Software-Defined Wide-Area Network (SDWAN) and determining, from a traffic policy, whether the traffic flow should be symmetrical. In response to determining from the traffic policy that the traffic flow should be symmetrical, the method further includes performing a flow lookup on the traffic flow to determine if the network device originated the traffic flow. In response to determining that the network device did not originate the traffic flow, the method further includes determining a second network device that originated the traffic flow and sending the handshake message for the traffic flow to the second network device in order to maintain symmetry for the traffic flow.
