A system is configured to: transmit requests to a first device and a second device; receive a first reply from the first device in response to one of the requests; determine an address of the first device based on the first reply; assign a first port to a first network when the first device is a first one of one or more devices that replied to the requests and have a same address as the first device; receive a second reply from the second device in response to another one of the requests; assign a second port to a second network when the address of the second device is the same as the address of the first device; and reassign the second port, from the second network, to the first network when a failure of the first device occurs.

In general, the invention is directed to techniques for identifying memory overruns. For example, as described herein, a device includes a main memory that enables an addressable memory space for the device. A plurality of memory pages each comprises a separate, contiguous block of addressable memory locations within the addressable memory space. The device also includes a memory manager comprising a secure pool allocator that assigns a secure pool size value to a first one of the plurality of memory pages. The secure pool size value defines a plurality of protected memory spaces in the first memory page that partition the first memory page into a plurality of secure objects. The device also includes a memory management unit comprising secure pool logic that determines, based on the secure pool size value, whether a memory address is an address of one of the protected memory spaces in the first memory page.

Secure pool memory management

A call handling system receives an asynchronous call request, from a call requester, requesting performance of an operation, where the call request includes a delay parameter specified by the call requester. The call handling system performs the requested operation, and sends a callback to the call requester, which includes partial results from performance of the requested operation, at selected intervals determined by the delay parameter.
