Data forwarding method and device

A data forwarding device, comprising a first logical ingress port, a first logical egress port, and a processor;

• wherein:
• the first logical ingress port is configured to obtain a first data unit sequence stream by using at least one timeslot of at least one physical ingress interface, wherein the first data unit sequence stream comprises at least one first data unit, wherein the first data unit sequence stream comprises an idle unit, wherein the idle unit is a 64B/66B idle block;
• the processor is configured to:
• determine, according to a preconfigured mapping relationship between at least one logical ingress port and at least one logical egress port, the first logical egress port corresponding to the first logical ingress port, wherein the at least one logical ingress port comprises the first logical ingress port;
• and
• increase or decrease a quantity of idle units in the first data unit sequence stream, so that a rate of an adjusted first data unit sequence stream matches a rate of the first logical egress port;
• and
• the first logical egress port is configured to send the adjusted first data unit sequence stream by using at least one timeslot of at least one physical egress interface.

A non-transitory computer readable medium storing program code thereon for data forwarding, the program code comprising instructions for executing a method that comprises:

• obtaining a first data unit sequence stream by using at least one timeslot of at least one physical ingress interface corresponding to a first logical ingress port, wherein the first data unit sequence stream comprises at least one first data unit, wherein the first data unit sequence stream comprises an idle unit, wherein the idle unit is a 64B/66B idle block;
• determining, according to a preconfigured mapping relationship between at least one logical ingress port and at least one logical egress port, a first logical egress port corresponding to the first logical ingress port, wherein the at least one logical ingress port comprises the first logical ingress port;
• increasing or decreasing a quantity of idle units in the first data unit sequence stream, so that a rate of an adjusted first data unit sequence stream matches a rate of the first logical egress port;
• and
• sending the adjusted first data unit sequence stream by using at least one timeslot of at least one physical egress interface corresponding to the first logical egress port.
