A method for tracking virtual machine usage includes deploying, by a client machine with a client Internet Protocol (IP) address, an instance of a virtual machine. The client machine generates an identification for the instance of the virtual machine and requests a domain name system (DNS) lookup for a domain name string from a tracker server specified by a tracker IP address, where the domain name string comprises the identification. The tracker server receives the DNS lookup from the client machine and records the identification and the client IP address.

Method of tracking usage of virtual machines

In one embodiment, a method and a system for reducing synchronization of data in a network is disclosed. The method includes generating a string based on the configuration in a first network device. Thereafter, the generated string is hashed to form a first integer. The first integer is used to identify an object. Subsequently, the identified object is utilized for synchronization between the first network device and a second network device. As a result, the need for synchronization of the data is reduced.

Method and system for reducing synchronization of data in a network

Disclosed are systems and methods for persisting management information indexes across multiple network elements. In particular, methods of detecting and curing potential collisions among a peer group of network elements by use of a hashing function can be provided in accordance with embodiments. For example, a method for maintaining persistence across network elements can include: (i) configuring one of the network elements, and providing a configuration string therefrom; (ii) performing a hashing algorithm on the configuration string to provide a hash value; (iii) determining if any collisions exists between the hash value and corresponding values from among a peer group of network elements; and (iv) assigning the hash value as a management table index when no collision is found, or assigning a new value for the management table index when a collision is found.
