Method for moving logical resources without explicit negotiations in a high availability, active-active service router cluster

One or more non-transitory computer-readable storage media storing one or more computer instructions which, when executed by one or more processors, cause the one or more processors to perform:

• determining, by an active service router (“SR”) from a plurality of service routers (“SRs”) implemented in an active-active SR cluster, that a particular SR has failed;
• obtaining, by the active SR, a plurality of hash values computed for the particular SR;
• wherein the plurality of hash values comprises a hash value determined for the active SR;
• determining, by the active SR, a maximum hash value of the plurality of hash values;
• determining, by the active SR, whether the maximum hash value corresponds to the hash value determined for the active SR;
• in response to determining that the maximum hash value corresponds to the hash value determined for the active SR:
• determining, by the active SR, whether the maximum hash value corresponds only to the hash value determined for the active SR;
• and
• in response to determining that the maximum hash value corresponds only to the hash value determined for the active SR, configuring, by the active SR, a port IP address of the particular SR on the active SR.

A service router implemented in a computer appliance node, the service router comprising:

• one or more processors;
• one or more memory units;
• and
• one or more non-transitory computer-readable storage media storing one or more computer instructions which, when executed by the one or more processors, cause the one or more processors to perform:
• determining, by an active service router (“SR”) from a plurality of service routers (“SRs”) implemented in an active-active SR cluster, that a particular SR has failed;
• obtaining, by the active SR, a plurality of hash values computed for the particular SR;
• wherein the plurality of hash values comprises a hash value determined for the active SR;
• determining, by the active SR, a maximum hash value of the plurality of hash values;
• determining, by the active SR, whether the maximum hash value corresponds to the hash value determined for the active SR;
• in response to determining that the maximum hash value corresponds to the hash value determined for the active SR:
• determining, by the active SR, whether the maximum hash value corresponds only to the hash value determined for the active SR;
• and
• in response to determining that the maximum hash value corresponds only to the hash value determined for the active SR, configuring, by the active SR, a port IP address of the particular SR on the active SR.
