In the area of Networking, Sarce covers various sectors with services which range from consultancy for network management to design and creation of highly reliable systems, from services for optimising performance to the definition of recovery strategies, from end-user training to network administrator to help desk.

Design of local area networks (LAN) and wide area networks (WAN):
Development of Wireless networks with connections protected by means of VPN, IPSEC and Microsoft authentication;
Development of extended networks (complex) with traffic optimisation using Vlan, Spanning Tree and Bridging techniques;
Development of Gigabit or FastEthernet type LANs;
Development of WANs with router connections on H/ADSL, Frame Relay, VPN and IPSEC;
Configuration of backbones for communications between remote sites via leased lines, packet switching, virtual networks over internet (PVN) with routers or RAS gateways;
Design of networks with connection of the company LAN to the Internet using high levels of security (Firewalls, Proxies, NAT);
Analysis and monitoring of traffic capacity for LANs and WANs.

Advanced Clustering (High Availability systems for Mission Critical applications):
Clusters under Windows 2003, Windows 2000 for providing continuity of service for company applications such as e-mail, file and printer sharing, database servers and third party applications;
Terminal Server service arrays for replacing company PCs with ThinClients (networkstation), to eliminate the maintenance of systems on the network and increase the stability of all the software;
Checkpoint or ISAServer firewall clusters to guarantee continuity of communications with sites having critical applications.

Activation of sites with SSL protected access using private and public keys;
Control of VPN access to the network through proprietary keys or SmartCards;
Control of access to the local network through SmartCards;
Encryption of data on the local network and in transit to the Internet;
Signatures and encryption of e-mail to guarantee the integrity and ownership of data transmitted via e-mail.

Connectivity with iSeries (AS/400) and mainframes (integration of networks with central systems):
Design of connectivity with IBM mainframe and AS/400 systems through direct connections or SNA Server gateways;
Remote configuration of connectivity between LANs and IBM mainframes or AS/400 systems;
