A method for optimizing network device resources , comprising:receiving, by an optimizer, first resource utilization data, the first resource utilization data comprises a utilization rate of at least one resource of the network device;determining that an optimization process is active;determining, based on the first resource utilization data, that resource utilization of the at least one resource is above a lower threshold;identifying a resource optimization entry of a resource class optimization queue;initiating optimization of a resource fragment specified by the resource optimization entry;{'claim-text': ['receiving second resource utilization data;', 'determining, based on the second resource utilization data, that the resource utilization is below the lower threshold; and', 'halting, based on the resource utilization being below the lower threshold, the optimization process.'], '#text': 'after initiating optimization of the resource fragment:'}22. The method of claim 21 , wherein prior to initiating the optimization of the resource fragment claim 21 , the optimization process further comprises: ...

Method and system for supporting distributed relay control protocol (drcp) operations upon misconfiguration

A method supporting a distributed resilient network interconnect (DRNI) in a link aggregation group at a network device is disclosed. The method starts with receiving a distributed relay control protocol data unit (DRCPDU), where the DRCPDU includes neighbor network device's state information and configuration information, wherein the configuration information includes its operational aggregation key, gateway digest, port digest. The method continue with determine whether or not the received configuration information is different from the one of the network device and how, and causing the next DRCPDU to be transmitted to the neighbor network device to include or not include certain information accordingly.

System, Method and Device for Forwarding Packet

Provided are a system, a method and a device for forwarding a packet. The system comprises: an LCC comprising a first LCC's control ether switch unit and a second LCC's control ether switch unit, a first CFC comprising a first CFC's control ether switch unit, and a second CFC comprising a second CFC's control ether switch unit, wherein a control message channel and a protocol packet channel are separately arranged between the first and the second LCC's control ether switch units and the first and the second CFC's control ether switch units. Through the disclosure, the problem that the reliability and security of the cluster-based router may be reduced if the control message and the protocol packet are transmitted in the same channel in the related arts is solved, so as to achieve the effects of forwarding the control message and the protocol packet in a cluster-based router separately and enhancing the reliability and the security of the cluster-based router. 1. A system for forwarding a packet , comprising:a Line Card Chassis (LCC) comprising a first LCC's control ether switch unit and a second LCC's control ether switch unit;a first Central Fabric Chassis (CFC) comprising a first CFC's control ether switch unit; anda second CFC comprising a second CFC's control ether switch unit, whereina control message channel and a protocol packet channel are separately arranged between the first and the second LCC's control ether switch units and the first and the second CFC's control ether switch units.2. The system according to claim 1 , wherein separately arranging the control message channel and the protocol packet channel between the first and the second LCC's control ether switch units and the first and the second CFC's control ether switch units comprises:a link between the first LCC's control ether switch unit and the first CFC's control ether switch unit serving as a control message channel, and a link between the second LCC's control ether switch unit and the second ...
