A method for managing port bandwidth in network devices. The method includes determining a first and a second ingress bandwidth of a first and a second network chip, respectively, determining an egress bandwidth of an egress port of a third network chip, determining a first and a second weight for the first and the second network chip, respectively, where the first and the second weight are determined based on a bandwidth including the first and second ingress bandwidth, processing a first data packet, received by a first ingress port administrated by the first network chip, based on the first weight and the egress bandwidth, and processing a second data packet, received by a second ingress port administrated by the second network chip, based on the second weight, and the egress bandwidth, where the destination of the first and the second data packet is the egress port.

Method and system for managing port bandwidth in network devices

A method for configuring network devices. The method includes selecting a first hash function to use to process packets using Equal-Cost Multi-Path (ECMP) on a network device, where the first hash function is selected from a set of hash functions using a second hash function, a network chip ID of the network chip in the network device, a network device media access control (MAC) address, and an ECMP flag. The method further includes selecting a third hash function to use to process packets using a Link Aggregation Group (LAG), where the third hash function is selected from the set of hash functions using a fourth hash function, the network chip ID of the network chip in the network device, the network device MAC address, and the LAG flag. The method further includes processing a packet received by the network device using the first hash function or the third hash function.

Method and system for preventing polarization in a network

A method for distributing time information in network devices. The method includes sending a first clock signal from a first system control device (SCD) to a PLL chip, sending a first time of day (TOD) from the first SCD to a line card system control device (LC-SCD), sending a second clock signal from a second SCD to the PLL chip and sending a second TOD from the second SCD to the LC-SCD. The method further includes synchronizing a third clock signal, generated by the PLL chip, to the first clock signal, if the first SCD is operational. The method further includes sending the third clock signal to a network chip, deriving, using the third clock signal, a first network-chip-internal clock signal and applying the first network-chip-internal clock signal to increment a network-chip-internal TOD to obtain a third TOD. The method further includes synchronizing the third TOD to the first TOD.
