Link aggregation using digests
View Patent ↗Methods, systems and computer readable media for link aggregation using digests are described. In some implementations, the method can include obtaining information about each port in a group of one or more ports. The method can also include computing a digest corresponding to each port in the group of one or more ports, the digest being based on the information about the corresponding port. The method can further include determining whether each port in the group of one or more ports is suitable for aggregation in a link aggregation group by comparing the digest corresponding to each port with a digest of a port in the link aggregation group.
1. A method for utilizing link aggregation in a shortest path bridging network, the method comprising:
obtaining, using one or more processors, one or more port configuration strings representing port settings of one or more corresponding ports;
computing, using the one or more processors, a digest of port settings for each of the one or more corresponding ports, wherein each digest includes 16 bytes and each of the port configuration strings has a number of bits greater than a number of bits in the digest; and
determining, using the one or more processors, whether one of the ports is suitable for aggregation in a link aggregation group by comparing the digest corresponding to the one port with a digest of another port in the link aggregation group.
2. The method of claim 1 , further comprising aggregating the port with the link aggregation group based on the determining.
3. The method of claim 2 , wherein the aggregating occurs according to a protocol.
4. The method of claim 3 , wherein the protocol is a link aggregation control protocol.
5. The method of claim 1 , wherein the configuration information includes an ISID and a VLAN identification.
6. The method of claim 1 , wherein the digest includes a value based on one or more of an ISID and a VLAN identification.
7. The method of claim 1 , wherein the digest includes a UNI configuration digest.
8. The method of claim 1 , wherein the obtaining is performed during startup of the one or more computing devices and is subsequently performed for a port when configuration of that port changes.
9. A system comprising:
one or more hardware processors;
a nontransitory computer readable medium coupled to the one or more hardware processors and having stored thereon instructions that, when executed by the one or more hardware processors, cause the one or more hardware processors to perform operations including:
obtaining one or more port configuration strings representing port settings of one or more corresponding ports;
computing a digest of port settings for each of the one or more corresponding ports, wherein each digest includes 16 bytes and each of the port configuration strings has a number of bits greater than a number of bits in the digest; and
determining whether one of the ports port is suitable for aggregation in a link aggregation group by comparing the digest of the one port with a digest of another port in the link aggregation group.
10. The system of claim 9 , wherein the operations further include aggregating the port with the link aggregation group based on the determining.
11. The system of claim 10 , wherein the aggregating occurs according to a protocol.
12. The system of claim 11 , wherein the protocol is a link aggregation control protocol.
13. The system of claim 9 , wherein the information includes an ISID and a VLAN identification.
14. The system of claim 9 , wherein the digest includes a value based on one or more of an ISID and a VLAN identification.
15. A nontransitory computer readable medium having stored thereon software instructions that, when executed by a processor, cause the processor to perform operations including:
obtaining one or more port configuration strings representing port settings of one or more corresponding ports;
computing a digest of port settings for each of the one or more corresponding ports, wherein each digest includes 16 bytes and each of the port configuration strings has a number of bits greater than a number of bits in the digest;
determining whether one of the ports port is suitable for aggregation in a link aggregation group by comparing the digest of the one port with a digest of another port in the link aggregation group; and
aggregating the one port with the link aggregation group based on the determining.
16. The nontransitory computer readable medium of claim 15 , wherein the configuration information includes an ISID and a VLAN identification.
17. The nontransitory computer readable medium of claim 15 , wherein the digest includes a value based on one or more of an ISID and a VLAN identification.
18. The nontransitory computer readable medium of claim 15 , wherein the digest includes a UNI configuration digest.
19. The nontransitory computer readable medium of claim 15 , wherein the obtaining is performed during startup of the one or more computing devices and is subsequently performed for a port when configuration of that port changes.
20. The nontransitory computer readable medium of claim 15 , wherein the aggregating occurs according to a protocol.
