The Eclipse Session Border Controller supports both IPv4 (RFC 791) and IPv6 (RFC 2460) applications and devices and it also provides IPv4 to IPv6 interworking. The Eclipse IPv4 to IPv6 interworking capability allows organizations to simultaneously support IPv4 and IPv6 devices and applications and to control their IPv4 to IPv6 migration.

IPv6 Benefits

IPv6 addresses many of the existing IPv4 limitations, as well as provides a wide range of new operational benefits and enhanced support for rich, multi-media applications.

• Large Address Space: IPv6 will ensure that the Internet can support a growing user base and the increasing demand for rich, interactive capabilities.


• More Efficient Routing: IPv6 delivers a new, more efficient routing infrastructure with smaller routing tables.


• Increased Security: IPv6 delivers a standards–based IPSEC solution for network security with assured interoperability between different IPv6 implementations.


• Enhanced Mobility: Mobile IPv6 allows an IPv6 node to arbitrarily change its location on an IPv6 network and still maintain existing connections.


• Better Management: IPv6’s auto-configuration makes it unnecessary for network managers or end users to configure IPv6 devices when they are connected to a network.


• Better Quality of Service (QoS): IPv6 headers allows routers to provide special handling for packets belonging to a flow (a series of packets between a source and destination).

Eclipse IPv4 to IPv6 Interworking

Eclipse is located where user SIP traffic first enters the network, Eclipse efficiently terminates, secures, controls and manages large numbers of SIP connections. To support service migration to IPv6 Eclipse supports IPv4 to IPv6 Interworking for SIP-based applications and devices. This capability makes it possible for organizations to begin incorporating IPv6 applications, services or devices into use as required. Eclipse IPv4/IPv6 Interworking enables:

• IPv4 (RFC 791) to IPv6 (RFC 2460) Interworking


• Coexistence between the protocols


• Service providers can roll out new IPv6-based services


• And migrate from IPv4 to IPv6 at their own pace

Eclipse at the access edge of any VoIP or real-time service deployment enables organizations to predictably scale, secure, control and manage user access to VoIP, IM, presence, or any other SIP service. And it does it equally across IPv4 and IPv6.
