Abstract

Embodiments of the present disclosure disclose a service sending method and apparatus, a service receiving method and apparatus, and a network system. The service sending method includes: obtaining, by a transmit-end device, an original data flow; inserting an increment tag p in the original data flow, to generate a first data flow, where the increment tag p is used to identify a quantity of changed idle units of the first data flow relative to the original data flow; and sending the first data flow. In the embodiments of the present disclosure, transparent transport of clock frequency and time phase information of a service is implemented.

First claim

What is claimed is:

1 . A service sending method, wherein the method comprises:
obtaining, by a transmit-end device, an original data flow; inserting an increment tag p in the original data flow, to generate a first data flow, wherein the increment tag p identifies a quantity of changed idle units of the first data flow relative to the original data flow; and sending the first data flow.

2 . The method according to claim 1 , wherein the inserting the increment tag p in the original data flow comprises:
obtaining a first segment data flow from the original data flow; determining a quantity of changed idle units of the first segment data flow relative to the original data flow; and inserting an increment tag p at a first location in the first segment data flow, wherein the first location is a location of a data unit that carries the increment tag p, and the increment tag p identifies the quantity of changed idle units of the first segment data flow relative to the original data flow.

3 . The method according to claim 2 , wherein the obtaining the first segment data flow from the original data flow comprises:
identifying a start unit of the original data flow; and determining a location of the start unit as the first location.

4 . The method according to claim 2 , wherein the obtaining the first segment data flow from the original data flow comprises:
setting a threshold of the increment tag p; identifying a first idle unit of the original data flow when the quantity of changed idle units of the first segment data flow relative to the original data flow is greater than or equal to the threshold; and determining a location of the first idle unit as the first location.

5 . The method according to claim 1 , wherein before the inserting the increment tag p in the original data flow, the method further comprises:
inserting or deleting n idle units in the original data flow; and determining the increment tag p according to the n idle units, wherein
p is equal to n when the n idle units are inserted; or
p is equal to −n when the n idle units are deleted.

6 . A service receiving method, wherein the method comprises:
receiving, by a receive-end device, a first data flow; extracting an increment tag p from the first data flow, wherein the increment tag p identifies a quantity of changed idle units of the first data flow relative to an original data flow; and restoring the first data flow to the original data flow according to the increment tag p.

7 . The method according to claim 6 , wherein the extracting an increment tag p from the first data flow comprises:
obtaining a first segment data flow from the first data flow; determining a first location in the first segment data flow; and extracting an increment tag p from the first location, wherein the first location is a location of a data unit carries the increment tag p, and the increment tag p identifies a quantity of changed idle units of the first segment data flow relative to the original data flow.

8 . The method according to claim 6 , wherein the restoring the first data flow to the original data flow comprises:
inserting p idle units in the first data flow when the increment tag p is greater than 0; or reducing idle units, whose quantity is an absolute value of p, from the first data flow when the increment tag p is less than 0.

9 . The method according to claim 7 , wherein the first location is a location of a start unit or a location of a first idle unit.

10 . The method according to claim 6 , wherein the method further comprises:
obtaining a clock frequency of the original data flow.

11 . A service sending apparatus, wherein the apparatus comprises:
a non-transitory memory storage comprising instructions; and one or more hardware processors in communication with the non-transitory memory storage, wherein the one or more hardware processors execute the instructions to:
obtain an original data flow;
insert an increment tag p in the original data flow, to generate a first data flow, wherein the increment tag p identifies a quantity of changed idle units of the first data flow relative to the original data flow; and
send the first data flow.

12 . The apparatus according to claim 11 , wherein the one or more hardware processors execute the instructions to:
obtain a first segment data flow from the original data flow; determine a quantity of changed idle units of the first segment data flow relative to the original data flow; and insert an increment tag p at a first location in the first segment data flow, wherein the first location is a location of a data unit that carries the increment tag p, and the increment tag p identifies the quantity of changed idle units of the first segment data flow relative to the original data flow.

13 . The apparatus according to claim 12 , wherein the one or more hardware processors execute the instructions to:
identify a start unit of the original data flow; and determine a location of the start unit as the first location.

14 . The apparatus according to claim 12 , wherein the one or more hardware processors execute the instructions to:
set a threshold of the increment tag p; identify a first idle unit of the original data flow when the quantity of changed idle units of the first segment data flow relative to the original data flow is greater than or equal to the threshold; and determine a location of the first idle unit as the first location.

15 . The apparatus according to claim 11 , wherein the one or more hardware processors execute the instructions to:
insert or delete n idle units in the original data flow; and determine the increment tag p according to the n idle units, wherein
p is equal to n when the n idle units are inserted; or
p is equal to −n when the n idle units are deleted.
