    摘要: Methods and apparatus for identifying a best path from a plurality of equal cost paths while accounting for service level agreement (SLA) metrics are disclosed. According to one aspect of the present invention, a method for routing a packet that has a payload using a node includes obtaining the packet, and adding an address of the node to the payload. Adding the address of the node to the payload creates an augmented packet. The method also includes identifying at least one element to which the augmented packet is to be routed, and providing the augmented packet to that element. In one embodiment, the method also includes storing ingress and egress timestamps associated with the node.

The template may be needed to decode the information included in an associated data record. The first template is sent on a first stream of a multi-stream protocol in an ordered fashion, such as SCTP. The one or more first data records are also sent on the first stream in an ordered fashion and include first flow information for data sent through a network device. A second template is sent on a second stream using the multi-stream protocol in an ordered fashion. One or more second data records are sent on the second stream including second flow information for data sent through the network device.

    摘要: 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.
