Covergence Session Manager SBC Feature Overview |

Overview of Covergence SBC Feature Set
The Covergence Session Manager combines traditional session border controller features with comprehensive security features and management tool to deliver the complete solution for the access edge. Its SBC features include:
| SBC Feature |
Description |
| SIP-aware NAT traversal |
Ensure that media can safely traverse near-end and far-end firewalls |
| Network topology hiding |
Prevents access from unauthenticated, malicious users |
| Authentication and access control |
Validates the identities of users and domains cryptographically to prevent unauthorized users from gaining access to network resources and corporate assets. Integrates with existing authentication and credentialing systems via standard protocols (RADIUS, PKI, DIAMETER, etc). |
| Denial of service (DOS) attack protection |
Detects abnormal signaling patterns and denies resources to sessions that match attack profiles to prevent the loss or degradation of service from brute force and precision denial of service attacks |
| Signaling validation |
Performs syntactic and semantic validation of signaling streams to prevent attacks based on the injection of malicious, invalid signaling information (e.g. buffer overflow attacks). |
| Media validation |
Ensures that media sessions between SIP user agents are the same as those negotiated during the session set-up. Prevents attacks that exploit the independence of SIP signaling and media channels. Prevents unauthorized consumption or theft of network resources (bandwidth). |
| Session admission control |
Limits calling activity based on administratively defined thresholds for session count, total bandwidth and/or observed quality of service (QOS) metrics. Session admission control policies can be defined on logical and/or physical network interfaces |
| Call detail recording |
Enables accounting and billing |
| Quality of Service (QoS) Control |
Helps minimize latency, jitter and packet loss for media sessions through application of layer-2 and/or layer-3 QoS marking and priority queuing policies to real-time signaling and/or media streams. |
