International Classification:

H04J 3/06

US Classification:

370503, 709223

Abstract:

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.

Abstract:

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.
