Capacities for calls in DMCC applications

The number of simultaneous active calls that Device, Media, and Call Control (DMCC) applications can expect to handle depends on many factors.

Compare the DMCC capacities listed in Table 1 and Table 2 with the Communication Manager resources and capacities described in capacities for DMCC to make sure that you have adequate Communication Manager resources for a given DMCC implementation.

Table 1. Non-server media (client media, telecommuter, and no-media)
Session and H323 Signaling Encryption Profile AE Server Capacity Traffic Rate for Applications
None 8,000 endpoints and a 36,000 BHCC on the following Avaya Common Servers:
  • All AE Services versions: Dell R610, Dell R620, HP DL360 G7, HP DL360p G8, Dell R630 and HP DL360 G9, or equivalent customer-provided server.

AE Services and Communication Manager can support up to 20 outstanding registration requests by an application at any time

If multiple CLANs are used, the client must distribute 20 outstanding registration requests evenly among allocated CLANs. If signaling encryption is used, the number of outstanding registration requests must not exceed 10.

PIN-EKE 3,200 endpoints and a 28,800 BHCC on the following Avaya Common Servers
  • All AE Services versions: Dell R610, Dell R620, HP DL360 G7, HP DL360p G8, or equivalent customer-provided server.

  • AE Services Release 7.1.2 onwards only: In addition to the above server list, Dell R630 and HP DL360 G9.

AE Services and Communication Manager can support up to 20 maximum registration requests by an application in a 10-second interval. Based on a recommendation of 5 registrations per CLAN, this can be reached by having 4 CLANs, which are able to process 5 encrypted registrations each. Note that the same limit of 20 registrations in a 10-second limit applies for Processor Ethernet also.

Developers need to consider this limit when designing applications (that is, a gap of 10 seconds is required between each set of 20 registrations if 4 CLANs are being utilized; a gap of 10 seconds is required between each set of 15 registrations if 3 CLANs are being utilized; a gap of 10 seconds is required between each set of 20 registrations if 10 CLANs are being utilitzed with 4 registrations per CLAN; and so forth).

H323TLS 2,000 endpoints and a 18,000 BHCC on the following Avaya Common Servers
  • All AE Services versions: Dell R610, Dell R620, HP DL360 G7, HP DL360p G8, Dell R630 and HP DL360 G9, or equivalent customer-provided server.

For more information see, Additional AE Services Restrictions.

AE Services and Communication Manager can support up to 20 registration, when sent by an application, in a 10-second interval. Avaya recommends 5 registrations per CLAN. 4 CLANs can fulfill the capacity for 20 registrations.
noteNote

The 20 registrations in a 10-second limit applies for Processor Ethernet as well.

Table 2. Server media
  Code Type AE Server Capacity Traffic Rate for Applications
No signaling and media encryption G729 120 endpoints AE Services and Communication Manager can support up to 100 maximum simultaneous registration requests by an application in a 10-second interval. Based on a recommendation of 20 registrations per CLAN, this can be reached by having 10 CLANs, which are able to process 20 unencrypted registrations each per 10-second interval. Note that the same limit of 100 registrations in a 10-second interval applies for Processor Ethernet also.

Developers need to consider this limit when designing applications (that is, a gap of 10 seconds is required between each set of 100 registrations if 10 CLANs are being utilized; a gap of 10 seconds is required between each set of 80 registrations if 4 CLANs are being utilized; and so forth).

G711 75 endpoints AE Services and Communication Manager can support up to 75 maximum simultaneous registration requests by an application in a 10-second interval. Based on a recommendation of 20 registrations per CLAN, this can be reached by having 4 CLANs, which are able to process 20 unencrypted registrations each per 10-second interval. Note that the same limit of 75 registrations in a 10-second interval applies for Processor Ethernet also.

Developers need to consider this limit when designing applications (that is, a gap of 10 seconds is required between each set of 75 registrations if 4 CLANs are being utilized; a gap of 10 seconds is required between each set of 60 registrations if 3 CLANs are being utilized; and so forth).

Signaling and media encryption G729 96 endpoints AE Services and Communication Manager can support up to 96 maximum registration requests by an application in a 10-second interval. Based on a recommendation of 5 registrations per CLAN, this can be reached by having 20 CLANs, which are able to process 5 encrypted registrations each. Note that the same limit of 96 registrations in a 10-second limit applies for Processor Ethernet also.

Developers need to consider this limit when designing applications (that is, a gap of 10 seconds is required between each set of 20 registrations if 4 CLANs are being utilized; a gap of 10 seconds is required between each set of 15 registrations if 3 CLANs are being utilized; a gap of 10 seconds is required between each set of 20 registrations if 10 CLANs are being utilitzed with 4 registrations per CLAN; and so forth).

G711 60 endpoints AE Services and Communication Manager can support up to 60 maximum registration requests by an application in a 10-second interval. Based on a recommendation of 5 registrations per CLAN, this can be reached by having 12 CLANs, which are able to process 5 encrypted registrations each. Note that the same limit of 60 registrations in a 10-second limit applies for Processor Ethernet also.

Developers need to consider this limit when designing applications (that is, a gap of 10 seconds is required between each set of 20 registrations if 4 CLANs are being utilized; a gap of 10 seconds is required between each set of 15 registrations if 3 CLANs are being utilized; a gap of 10 seconds is required between each set of 20 registrations if 10 CLANs are being utilitzed with 4 registrations per CLAN; and so forth).

noteNote

Traffic rate for applications is a gap of 10 seconds between each set of 100 registrations.
