Queuing of packets and encryption/decryption processing in routers add enough delay that plain encapsulation of legacy protocols
usually fails to work over these high latency transports.
Skilled programmers adept at legacy protocols
are difficult to find in today's marketplace since most recent college graduates receive limited exposure to SNA, X.
To meet these challenges, NCR and Simpact have formed a strategic alliance that leverages NCR's worldwide presence and IP networking preeminence with Simpact's leadership in legacy protocols
and IP migration solutions.
They continue to rely on SNA and other legacy protocols
typically found in mission-critical networks, while simultaneously adding newer applications such as remote access for small offices and telecommuters.
Protocol spoofing of SNA/SDLC, BSC, ALC and other legacy protocols
protects against dropped sessions, eliminates unnecessary traffic and improves throughput and response time, while further lowering overall network expense.
NodeX1[TM] is compliant with legacy protocols
and can be easily configured on subnets with multiple protocols.
The security envelope is easily extended so organizations can integrate legacy protocols
and devices onto a common network infrastructure alongside new IIoT devices.
Given its enhanced reliability, scalability, security and flexibility over legacy protocols
, Diameter has been chosen as the de-facto signalling protocol in all next generation fixed and mobile IP-based networks, such as IMS and the LTE Evolved Packet Core (EPC) network.
Similarly, the new multi- core LLP enables the transport of multiple legacy protocols
across wireline packet networks.
The Cisco software and hardware solution needed to address interoperability with multiple legacy protocols
and interfaces from third party equipment, with the solution customised, designed and implemented by Cisco Gold Certified Partner Datanet Systems.
All legacy protocols
(DS0, DS1, E1, ATM, and IMA) may be tunneled concurrently within up to 128 pseudowire connections over PSN networks.
SIP offers several advantages over legacy protocols
as it assists equipment vendors and service providers in creating innovative solutions for next-generation networks.
As large networks utilise legacy protocols
, SIP will need to co-exist with them to gain greater acceptance.
